New file
0,0 → 1,1700
30 May 2003 JpGraph 1.12.2
==========================
* [me & A. Tang] Added support for Chinese font and character handling.
This requires you to install the "simhei.ttf" Chinese font.
 
* [J Sweat] Fix bug [#124] Make step line style ignore NULL values in data
 
* [J Sweat] Fix bug [#123] Divide by zero for line length of zero for dashed lines
 
* [me] Fix bug [#109]. Problem with pie color when a supplied color array
contains more colors than data. For anti-aliased images that meant that
the last n colors was used and not the first n colors.
 
* [me] For plotmarks that use the ALT string the wrong value was in due
to the recent addition of both Y and X value to control the plot callback.
This has now been fixed so that it will work as before and that previous
code that assumes one parameter in their ALT srting will see the Y-value at
the plotmar. New is also that the X-value is given as a second
parameter. This means that the ALT string can display both the Y and X value
for a specific point.
* [me] Make it possible to disable individual plot legends through the method
Plot::HideLegend()
 
* [me] Fixed problem with SetTextTickInterval() together with grouped bars
(bug #116)
 
* [me] Fixed a problem with shadows on accumulated bar plots (bug #111)
 
* [me] Fixed Legend::SetMarkAbsSize()
 
* [me] Add error check for the case that the server (Windows)
doesn't support SystemRoot and TEMP server variables.
 
* [me] Fix short-open-tags bug that made it's way into 1.12.1 (bug #121)
 
* [me] Make sure we only pass integers into GD when positioning texts.
 
* [me] Always treat "" (empty string) as NULL for bar plots
 
* [me] Allow links from vertical position 0 on gantt charts
 
 
12 Apr 2003 JpGraph 1.12.1
==========================
 
* [me] Added Legend::SetLineSpacing() to control the vertical line
distcance (in pixels) between legend texts.
 
* [me] Compensate for bug in imagecopyresampled() in GD 2.01.
This made clipping unusable with GD 2.01
 
* [me] Added LinePlot::SetFillFromYMin() to make the fill start from
the bottom of a Y-scale with negative values rather than the 0-value
which is now the case.
 
* [me] Fix a problem with legend box layout in the case of TTF fonts
and different lengths of individual texts. The layout engine now
work out each column individually. This will also give the legend
box the minimum possible size.
 
* [me] Compensate for possible bug in strtok() when parsing color
specification as a string with adjustment factors.
 
 
06 Apr 2003 JpGraph 1.12
========================
* [me] Added possibility to specify the position of the legend box
with absolute pixels coordinates not only as fractinos as before.
 
* [me] Improved legend layout. It is now possible to specify
the number of columns in the legend box. The preferred way of
specifyin the layout is now Legend::SetColumns(). The oild
way with SetLayout() is still available for backwards compatibility
reasons. The old vertical layout corresponds to a 1 column
layout (SetColumns(1) which is also the default).
 
* [me] Added possibility to specify text string position
using scale coordinates onto the plot by adding
Text::SetScalePos(). The autoscaling has been modifyied to
be aware of the text scale positions.
 
* [me] Added builtin images for plotmarks. This also meant a
refactoring exercise for the PlotMark class and it has now been
split in sevaral files.
 
* [me] Added footer capability to Radar, Pie and Gantt charts
 
* [me] Improved upon rounding problem with GD2 and pie slices
(defect #88)
 
* [me] Take shadow color as specified with Graph::SetShadow() into account.
 
* [me] Don't rotate the footer if the graph is rotated.
 
* [me] Added Axis::HideLabels()
 
* [me] Adjusted of the automatic margin calculation so that it is
aware of when the x-axis have been hidden.
 
* [me] Added PlotMark::SetCallbackYX(), This allows for the
specification of a callback function which is given both X and Y
coordinates. Also extended the returned values from the callback so
that image in a marker can be dynamically modified both size and
actual image file used. This will enable the use of advanced
"push-pin" graphs. For example adding markers to a background image
map of certain size and type.
 
For backwards compatibility any callback specified with
PlotMark::SetCallback() will not be given the extra parameter. So
old code does not need to be changed.
 
* [me] Fixed handling of PHP array URL parameters with CSIM. [Bug #82]
 
* [me] Added Legend::SetFrameWeight() which adjusts the frame around
the legend. Legend::SetLineWeight() now works as documented and sets
the line weight for the markers instead.
 
* [me] Autoscaling will now also take the value of added lines into account.
 
* [me] Fixed problem with horizontal legend box becomming too small
for many legends.
 
* [me] Radar plot. SetColor() always sets a fill color. Fixed (Bug #83)
 
* [me] Added SetWidth() for tab-title. The tab can now easily extend
over the entire plot width. Added SetPos() as synonym in tab title
for SetTabAlign().
 
* [me] Gradient bar plots now show a gradient mark in the legend
 
* [me] PiePlot3D::SetSliceColors() now more correctly specifies the
color anti-clockwise. The same order that slices are drawn.
 
* [me] Pie position can now also be specified in absolute pixels
in PiePlot::SetCenter()
 
* [me] Added Bevel frame for entire graph
 
* [me] Added possibility for some more advanced Graph title
formatting through the Graph::SetTitleBackground() method.
 
* [me] Type safe comparison in auto-detection of GD version
 
* [me] Added Graph::SetCanvasColor() to specify the background color
the canvas is initialized with.
 
* [me] Fine tuned label positiong for pie labels and made 3D pies
take the specified labels into account.
 
* [me] Added Anti-aliasing to Pie charts. Looks good but it really
slows down the pie generation. Enable by acalling
PieGraph::SetAntiAliasing()
 
* [me] Ignore NULL values in Stock and bar plots
 
* [me] Some minor internal adjustments for rounding in log scales.
 
 
2 Feb 2003 JpGraph 1.11
=======================
* [Martijn] Compensate for GD 2.x bug in filledarc() which doesn't
like negative angles.
 
* [me] Added Graph::SetBackgroundGradient() . This allows
a gradient to be used as a background. The gradient can either fill
the whole frame, only the margin or just the plot area. See the
class reference or the manual for details regarding this method.
 
* [me] Modified adjustment factor for colors so that it now
is linear between dark and light, i.e. a factor of 1 is the original
color, a factor of 0 is black and a factor of 2 is white.
 
* [me] Added two new gradient style GRAD_LEFT_REFLECTION and
GRAD_RIGHT_REFLECTION
 
* [me] Some fine tuning of text layout in legend box
 
* [me] Radar plots can now have a background image and multiple
titles (sub-title, and subsub title).
Added RadarGraph::SetPos() as alias for
RadarGraph::SetCenter().
 
* [me] Fixed a small pre-read-loop error which could casue the
X-gridline to be outside the right edge of the plotarea if the
X-scale was indented.
 
* [me] Added possibility to use (scaled) images as markers by
introductin the new mark type MARK_IMG.
 
* [me] Added tab titles for graphs. See class reference and Example
tabtitleex1.php.
 
* [me] Added filled grids by adding method Grid::SetFill(). This new
feature is illustrated in example filledgridex1.php. Documented in
section 6.2.11 in the manual.
 
* [me] Improved automatic margins so they adapt to one or more title
lines automatically.
 
* [me] Fixed a class hierachy bug. RotImage::DashedLine() should not be
implemented but rather rely on the Image::DashedLine() since the
rotation will happen in the RotImage::Line() which gets called in
Image::DashedLine() by any istance of RotImage().
You could see the ffect of this by trying to create a 90 degrees
rotated graph with dashed gridlines, they would appear not to be
rotated at all where in fact they were rotated twice.
 
* [me] Added automatic default margins when using Set90AndMargin()
 
* [me] Added Box plots which is a variant of Stock charts with the
possibility to add the median as a horizontal line in the box.
 
* [me] Added Stock charts, (aka candle-bars) as new class StockPlot().
added example stockplotex1.php in the Example directory.
 
* [me] Added two new axis styles AXSTYLE_YBOXOUT, AXSTYLE_BOXIN which
suplicates the Y-axis on both sides but not the X-axis.
 
* [me] Set90AndMargin() now also adjusts the label alignment on the
axis to suit the rotation.
 
* [me] Added class LineErrorPlot which alolows a line plot to
have error bars (+/- delta error).
 
* [me] Added Ticks::SetSize()
 
* [me] Modified size for plot mark circle so it will have the
specified width as radius and not as diameter.
 
* [me] Added Ticks::SetSize() to be able to set the absolute size
in pixels of the tick marks.
 
* [me] Default directories for Fonts and Cache now gets set
automatically.
 
 
13-Jan 2003 JpGraph 1.10.1
==========================
 
* [me] Fix bug in Band pattern Left diagonal and Right Diagonal where
the drawing was incorrect when width < height
 
* [me] Take the border on/off switch into account for line AddArea()
 
* [me] Added color parameter to Axis::SetTickLabels() to make it
possible to set individual colors on labels.
 
* [me] Fixed PiePlot::SetSliceColor() so that colors are now specified
in the same order as slices.
 
* [me] Gantt, Radar and Canvas graph now also considers the special file
_IMG_HANDLER (returns the actual image handler and doesn't stream
picture back)
 
* [Christian Reiser] Pie graphs can now also return the IMG_HANDLER
 
* [Richard Black] Removed case sensitivity for extension of
background images. Added support for handling file names with
multiple '.' characters in the path for background images.
 
* [me] Added error check for imagettfbbox() since it can give
a file not found error even though both file_exists() and
is_readable() reports that the file exists and is readable
in the case when PHP basedir restriction is in place.
 
* [me] Corrected CSIM handling in Gantt for non-file based
Gantt charts.
 
* [me] Note to self: 1.10p
 
* [me] Gracefully handle the abnormal case where no valid data points
is included in the Y-data array when creating a line plot.
 
16-Dec 2002 JpGraph 1.10
========================
* [me] Added GanttGraph::CreateSimple() whihc is a utility method to
help create simple gantt charts with a minimum of code.
 
* [me] Added new plot (FieldPlot) type which handles field plots. This is
basically a variant of scatter plots where each point is represented
as an arrow which a specific direction (0-360 degrees).
 
* [me] Added Graph::SetY2OrderBack() to control of plots on Y2 should
be under (in z-order) te plots on Y. By default they are on top.
 
* [me] Avoided a potential 1-pixel off rounding problem if a user
supplies a non integer canvas width and height in the Graph() call.
 
* [me] Added two new formats for week scale in Gantt
charts. WEEKSTYLE_FIRSTDAYWNBR, WEEKSTYLE_FIRSTDAY2WNBR These
formats adds the weeknumber as well to displaying the date of the
start of the week. Also tweaked the auto-sizing of the Gantt charts
to adjust for the size of the text in the week scale.
 
* [me] Fixed wrong define in jpgraph_gantt.php for WEEKSTYLE_DAY2
(Bug #45)
 
* [me] Improvements on manual scaling. If a manual scale is specifed
(in the Graph::SetScale()) you are now longer required to specify a
major and minior tick interval (but of course you can still do it
with a call to Ticks::Set() ).
A suitable intervall will be automatically
caclulated in the same way as for autoscaling. By default the exact
limits for the scale as specified will be used. This means that
depending on the scale and tick intervall chosen the max value of
the scale may or may not fall on a major tick mark. If you want that
behaviour you need to call Scale::SetAutoTicks(). By using this call
you give the algorithm permission to slightly adjust the specified
min and max values (if needed) so that they wil fall on a even
major step.
 
* [me] Added error check if user tries to use SetTextLabelStart()
with a logarithmic scale (where it is undefined).
 
* [me] Default marker for scatter plots are now a filled square
 
* [me] Adjusted the x-axis labelling for a 1-pixel off limit. Which
sometimes (depending on the image size and scale) could cause a
linear scale's last label not to be shown.
 
* [me] Fixed bug report #40
 
* [me] Fixed positioning of caption for full odometers. (Bug #34)
 
* [me] Fixed spelling mistake in jpgraph_odo.php which casued
Odometer::SetLabelPos() to have no affect. (Bug #33)
 
* [me] Fixed an overzeoulous optimization which skipped both rotation
and translation for angle=0. Addresses (Bug #36)
 
* [me] Colors can now include an alpha channel specification as well.
The alpha channel is specified in the text string separated by a
a '@' , for example "red@0.5". The alphachannel is specified as a
fraction between 0.0 and 1.0.
 
* [me] Improved filled line plots so they now handle negative values
in a more standard way.
 
* [me] Added automatic detection of what version of GD is installed.
 
* [me] Aligned the order of legends and slices for pie and 3D pies so
that they now follow the more common order of clockwise slices with
legends from top to bottom.
 
* [me] Changed call to deprecated function SetLinePos() to SetLineSide()
 
* [me] Added clipping to generated plots. This means that if you have
plots (for example lines) which extends outside the scale range it
will be clipped. This might come in handy in for example balloon
plots. Clipping is enabled by default but can be controlled by a
call to Graph::SetClipping()
* [me] Fixed a problem with circles and filled circles when they were
rotated twice in a rotated graph. (Bugtraq #26)
 
* [me] Added Graph::Set90AndMargin() which helps for doing a 90
degrees rotation and getting the margins right. (Otherwise you have
to adjust them manually since height becomes width and width becomes
height when you rotate 90 degrees)
Changed the horizbar* examples to use the Set90AndMargin()
 
* [me] Changed the behaviour of plot marks in legends. The possible
format callback is no longer called. Instead the plotmarks are
set to a default size.
 
* [me] Added three more plotmarks MARK_LEFTTRIANGLE,
MARK_RIGHTTRIANGLE, MARK_FLASH. These new types are primarily meant
to be used with GanttCharts.
 
* [me] Added constrain lines to GanttCharts. It is now possible to
illustrate start-end, start-start, end-start and end-end
constrains. This is illustrated by adding lines with arrows,
Use GanttPlotObject::SetConstrain()
 
* [me] Added Image map support for Gantt chart. Bar and titles can now
have associated image map targets. Use GanttBar::SetCSIMTarget()
GanttBar::SetCSIMAlt() and for titles use
GanttBar::title::SetCSIMTarget() and GanttBar::title::SetCSIMAlt()
 
* [me] Fix problem in Gantt graph whereby the progress bar indicator
could extend over the end date if an explicit date scale was set.
 
* [me] By default logarithmic scale now print the labels as 10^3
instead of 1000. You can change the behaviour with the new
method for logarithmic ticks, SetLabelLogType().
Also added the possibility to have a callback for log scales
 
* NOTE TO SELF 1.9p
 
* [me] Added the possibility to specify a value > 1 as the position
for labels in PieGraph::SetLabel() to increase the margin between
the label and the edge of the pie.
* [Olaf Kandel] Fixed subtle bug in the printing of the month scale for the
case where the start and end month hjave the same number but
are on different year. This would cause the width for the
first month to be wrong.
 
 
Jpgraph 1.9.1
=============
* [me] Fixed defects #20 and #21 (spelling mistake and and one
overzelous last minute error check I added). I have to eat a lot
of humble pie over these ones. Sorry to all who have been affected.
What can I say? Human error........
 
JpGraph 1.9
===========
* [me] Changed the way TTF fonts are handled. The font files are no
longer distributed with JpGraph due to potential copyright problem.
This change also has the advantage that it is now very
straigthforward to install new fonts whatever their naming
conventions are.
 
1. If you are running on a standard Windows system just point the
TTF directory to your standard font directory and use the available
fonts in windows.
 
2. If you are on a Unix system you can download the MS Core TTF
files from http://corefonts.sourceforge.net/. The old MS EULA allows
distribution of the fonts in unaltered form (Win EXE) and this
project exercises this right and provide tools to download and
install the fonts on a UNIX system.
 
* [me] Renamed this release from 1.8.1 to 1.9 due to the big
change in the handling of TTF fonts which breaks backward
compatibility due to the copyright problem with TTF fonts.
 
* [me] Improved the TTF pargagraph layout engine for consistency
in handling "\n\r" vs "\n". It is now always sufficient to
use just "\n".
 
* [me] Adjusted the text positioning for StrokeBoxedText()
to use the new GetBBoxHeigh() and GetBBoxWidth().
 
* [me] Added Image::GetBBoxHeight(), Image::getBBoxWidth()
 
* [me] Once and for all fixed the handling of rotated TTF text by
adding Image::GetBBoxTTF() which returns the bounding rectangle
(which is not the same as the bounding box except for angle==0)
 
* [me] Added argument to Legend::SetColor() to make it possible
to specify both frame and font color.
 
* [me] Cosmetic adjustment of markers in legend so that they are
positioned exactly in the middle of the text string.
 
* [me] Corrected the positioning of TTF fonts when defining the
hotspot as 'bottom'. It could be up to 4 pixel off when using
texts that contained character that extended below the TTF
baseline e.g. '('.
 
* [me] Added possibility to use a cache system with CSIM images
as well. The cache system is used slightly, slightly different
and require a call to the new method Graph::CheckCSIMCache()
This is unfortunately unavoidable due to the nature of CSIM in
HTML. The documentation is updated to deal with this. This also
added two more defines CSIMCACHE_DIR and CSIMCACHE_HTTP_DIR
 
* [me] Added CSIM (Client Side Image Maps) to legends, added
target and alt arguments to all Plot::SetLegend()
 
* [me] Added functionlity to pass on any URL arguments when using
StrokeCSIM() (Bug: #006)
 
* [me] Fixed so that Gantt charts can again have just the width
specified and have the height automtically sized. (This was a
regression introduced in 1.8) (Bug #005)
 
* [me] Added error check for return value from imaagecolorsforindex()
in Anti-aliased lines. In combination with GD2, no-true-color, a
true color background (ala JPG) this can fail since it gets a color
which doesn't exist (since it uses imagecolorat()).
 
* [me] Improved edges support in 3D Pies.
 
* [me] Changed Image::Polygon() so i now draws an open polygon and not
a closed one.
 
* [me] Legends for scatter plots no displays the mark used for
each scatter plot and not just a square with the correct
color.
 
* [me] Fixed a small cosmetic problem in that horizontal legend
box was sometimes not wide enough and made a small adjustment
of the positioning of marks in the legend box for better
apperance. (Bug #0017)
 
* [me] Improved manual by adding linked TOC.
 
* [me] Added Bezier curve to canvas Shape class. Added Bezier canvas
example canvasbezierex1.php
 
* [me] Added Paragraph Alignment setting in Text::Align() as well to
avoid seprate call to Text::SetParagraphAlign()
 
* [me] Added Image::SetExpired() . By default the image now sends
back a couple of variants of "no-cache" headers to force the browser
to reload.
 
* [me] Some serious speed improvments for 3D Pie plots. It can now be
up to 6000% faster (yes that's right 6000%!). This is the way I had
planned on doing it but for time reasons were pushed out of 1.8.
I have completely changed the algorithm that handles the individual
slices on the expense of a slightly more complicated implementation.
This means that there is no performance difference between 2D and
3D Pie Plots.
 
* [me] Fix bug for rotation of paragraphs (multi-line) texts.
A limitation for now is that rotated pargraphs always gets
paragraphs align "left". (Bug: #008)
 
* NOTE TO SELF: 1.8p
 
* [me] Fixed a typo that had the strange affect that paragraph strings
which started with a number would have larger distance between the
individual lines since that number would be interpretated as the
angle for the text!
 
* [me] Fixed a problem with marks getting out of sync if NULL values
are present in the line plot. (Bug #0018)
 
* [me] Scatterplot no skips NULL values instead of treating them
as zero.
 
* [me] Added LinearScale::SetAutoMax() as complement to SetAutoMin()
 
* [me] Added LinearScale::SetAutoTicks() this makes it possible to
manually set a scale but still have the tick marks automatically
determined. By default this feature is off to keep old code
behave exactly the same as before. If this is enabled any
Ticks::Set() calls are ignored.
 
* [me] Added possibility to adjust the position of the displayed
value for bars via the BarPlot::SetValuePos() method. Added new
example example20.5 to demonstrate this.
 
* [me] Bugfix: Fixed color themes for 3D pie plot. The color array
was not wrapped around in the case where more slices (data points)
than colors is used. (Bug: #001)
 
* [me] Documentation is now 100% pure HTML and does not require
any PHP. Previously a PHP script was used to generate the
highlighted source used in the image/source frames. All this
is now pre-generated in the docs.
 
* [me] Position the values in a scatter plot in the center of the
plot mark by default (Setting align to 'center','center' and margin=0
 
* [me] Added LinePlot::SetBarCenter to make it possible to center the
line on the bars when combining a plot with both bars and lines.
The new example 'ceneterdlinebarex1.php' demonstrates this.
 
 
 
[19-Sep-2002] JpGraph 1.8
=========================
* [me] Added Text::SetPos() as alias for Text::Pos() to harmonize with
other setting methods.
 
* [me] Made Graph::Add() polymorphic. You can now use Graph::Add() to
add all plot objects and you don't longer have to use AddText(),
AddLine(), AddBand() and so on.
 
* [me] Added PiePlot::SetLabelPos(), added some more Pie examples.
 
* [me] Improved the API for class Text by adding SetShadow() to make
it more like the other objects. Extended Text::SetBox() with shadow
width and corner radius.
 
* [me] Added the possibility for Text object to use the new rounded
rectangles as the filled background.
 
* [me] Added possibility to add arbitrary labels inside the pie plot
 
* [me] Added special filename __IMG_HANDLER to make it possible to
have Graph::Stroke() return the image handler instead of stroking
the image to file (or stream it back).
 
* [me] Improve FilledCircle() to avoid moire-patterns in circle.
 
* [me] Added middle type pie plot
 
* [me] User specified values for the band position is truncated to the
min and max values of the axis.
 
* [me] Added possibility to use Text::SetMargin() for all the titles
in a graph
 
* [me] Added SetSize() as synonym for SetWidth() for plot marks.
 
* [me] Updated some of the examples with more comments.
 
* [me] Fixed problem with with jpg background images wrongly being
loaded with imagecreatefromjpg instad of imagecreatefromjpeg
 
* [me] Corrected the positioning of individual titles for 3D
plots.
 
* [me] Added Text::SetMargin() to make it easy to have context
sensitive margins.
 
* [me] Added capability to have background images on Pie and 3D
Pie plots
 
* [me] Added method Axis::HideLine() which hides the axis line but
nothing else.
 
* [me] Fixed bug in Stroke::Text() where negative coordinates
wasn't properly handled. We must allow negative absolute
coordinates since these might be rotated/translated into
"real" screen coordinates. This fixes the bug, for example
in bar_csimex1.php where the first value of the bar wasn't
displayed.
 
* [me] More adjustment of how the rounding takes place with
coordinates. This should now avoid all potential difference
between different graphic objects.
 
* [me] When you use automatic labelling on text scale it now starts
at 1 and not at 0. This makes more sense since most people (except
mathematicians) start counting from 1.
 
* [me] Example directory:
- Added more advanced canvas examples
- Updated all CSIM examples
- ~60 new example script which are used in the new documentation
 
* [me] Compensate for bug in imagettfbox() which return to small size for
large fonts.
 
* [me] Added jpgraph_canvtools.php which contain some utility classes for
use with canvas graphs.
 
* [me] DOCUMENTATION: The class reference is now included in the release.
 
* [me] DOCUMENTATION: Completely rewritten the original
Word-introduction to JpGraph to pure HTML. This will be a living
document that will be updated as time moves on. This is currently
considered "Beta" and more chapters need to be added but this is
a good start!!
 
* [me] Added full support for multiline legends. (See for example
nullvalueex01.php. Also improved the way lineplot with marks
are illustrated in the legend by adding the line underneth the
plotmark.
 
* [me] Added some utility classes to be able to draw DB schema for
DDDA. This is tailored for my DB abstraction layer (jpdb.php)
in DDDA but is generic enough to work in other circumstances as well.
The classes can be found in utils/misc/imgdbschema.inc
Please see (run) dbschema_ddda.php which shows how it looks
in a real life example.
 
* [me] Tweaked the positioning of TTF fonts and how the width and
height are determined. Making more carefull assumptions about
how the baseline is handled for individual lines of text.
 
* [me] Added class RectangleText() which makes it easier to work
with text inside a rectangle with rounded corner.
 
* [me] Added support for multi-line TTF paragraphs with paragraph
formatting. This was previously only supported for the builtin
fonts. All text object should now support fully formatted paragraphs
of text.
 
* [me] Added Image::RoundedRectangle() and
Image::FilledRoundedRectangle()
 
* [me] Added format callback to plot marks. This makes it
possible to individually adjust the plot marks depending
on it's specific data value. See balloonex1.php
 
* [me] Added some initial support for super script used for
scientific numbering, i.e properly print for example 10^2
where the 2 is in superscript. This is all handled by the
new class SuperScriptText(). Not yet used in the actual
labels drawing but will be added shortly.
 
* [me] Added a small tool mkgrad.php in the utils directory to
make it a breeze to create gradient squares which may be
used as background images.
 
* [me] Added footer class to graph. This makes it easy to have
left,center and right footers in your graphs.
 
* [me] Added subsubtitle to graphs
 
* [me] Improved/Changed the way you work with CSIM. This new method
makes it possible to generate CSIM without having to create an
intermediate image on disk.
Added Graph::StrokeCSIM(). Added new chapter in the docs on how to
work with CSIM
 
* [me] Changed naming of Spider* to Radar* since SpiderGraph is a
copyrighted name.
 
* [me] Modified the automatic suppression of the first value of the
X-axis when the Y-axis have negative value so it don't happen
in the case where the X-axis is positioned at the minimum of
the Y-axis.
 
* [me] Fixed spelling error of BK* instead of the correct BG*
for the default settings of background image style.
 
* [me] Some internal code changes to RGB() class to make it easier
to use directly for external scripts.
 
* [me] Changed the behaviour of filled line plot so that they
don't go down to 0 for null values in the plot but instead
behaves like '-' for non-filed plots, just ignore them and
connect the previous and next point instead.
 
* [me] Fixed problem in integer scaling where it certain scale
combinations could generate floating point labels! Ooops..
(Affects IntCalcTicks())
 
 
[5-July-2002] JpGraph 1.7
==========================
* [me] Removed the APACHE_CACHE_DIRECTORY define since it is
not used.
 
* [me] Added Image map functionlity for rotated bar graphs,
also added new example for this (bar_csimex3.php)
 
* [me] Made Ticks::SetPrecision() deprecated. Use SetFormatString()
instead
 
* [me] Fixed problem with incorrect string being returned from
ToCyrillic()
 
* [me] Allow Y2 axis to use "int" scale
 
* [me] Fixed problem with wrongly names framework function for
patterns
 
* [me] Fixed small problems with margins being slightly off for
roated images.
 
* [me] Changed name of PlotMark::SetMarkColor() to PlotMark::SetColor()
for consistency
 
* [me] Added example with "hidden" Y-axis.
 
[17-June-2002] JpGraph 1.7-BETA
===============================
* [me] Added DisplayValue::SetFormatCallback() to make it possible to use
a user specified formatting callback routine.
(Note:: Yes, this is very nono-OO but the proper OO way, by forcing the
user to define a subclass of the plot class where the formatting method
is overridden will probably not fly with to many non-OO PHP peoples since
a callback is conceptually simpler.)
 
* [me] Added DisplayValue::HideZero(). Makes it possible to hide zero values
in labels, for example zero slices in pie's, (e.g. $pieplot->value->HideZero())
 
* [me] Added manual scaling to Gantt graphs, added example to illustrate
this, fixscale_gantt.php
 
* [me] Adding image maps for Y2 scale as well.
 
* [me] Fixed a small bug which made it impossible to use BRAND_TIMING with
Gantt charts. Enabling timestamping of graphs would give a "PlotArea to small"
error.
 
* [me] Made a very small change to the AutoScaling algorithm to yield tighter
boundaries, i.e with the existing algorithm, depending on rounding problems
a plot which had a maximum value of, say 4, could get a autoscaling max
value of 5. Not a big problem (or hardly a bug) but not what I wanted.
All my 111 test cases works fine with the modification but I'm still
not convinced that this (very minor) adjustment is 100% (I can distinctly
remember that I had a good reason to do it the original way, I just can't
remember what :-)
 
* [me] Graph titles may now have multiple rows. By default the lines will
be centered, but this may of course be adjusted by a call to, for
example, $graph->subtitle->ParagraphAlign('left');
 
* [me] Added class FuncGenerator() to make it easy to generate
function plots (both normal and polar). To illustrate this I have
added three new examples funcex1.php,funcex2.php,funcex3.php.
 
* [me] Added Axis::HideFirstLastLabel() to hide first and last label on
axis. This is usefull if we have a box around the plot area and we don't
want the labels to owerwrite the box (see funcex1.php)
 
* [me] Make sure GD2 variables is registred in $GLOABALS[]
 
* [me] Fixed bug in image maps for marks. Alt strings was incorrectly
indexed so it was only using values 0,2,4.. instead of 0,1,2,...
 
* [me] Added Graph::SetAxisStyle(). This makes it easy to use
a few number of preset axis setup. For example duplicating the axis
as a border around the plot. Preset axis position availabel are
AXSTYLE_SIMPLE, AXSTYLE_BOXIN, AXSTYLE_BOXOUT
 
* [me] Made Axis::SetTickLabelMargin() deprecated. Use
Axis::SetLabelMargin() instead. Name change to make it more
consistent with the other margin settings.
 
* [me] Made Ticks::SetSide() a synonym for Ticks::SetDirection()
to make it consistent with side setting for labels and values.
 
* [me] Added Axis::HideZeroLabel() as a shortcut for
axis->scale->ticks->SupressZeroLabel()
 
* [me] Internal code changed. Replace the use of FontProp in SpiderGraph
with Text() and some additoinal code cleanup.
 
* [me] Adjusted Image::Arc() so that no negative angles are
passed on to GD imagearc() since it barfs at negative angles.
 
* [me] Added PiePlot3D::SetHeight() which is used to specify the
height in pixels of the 3D pies instead of using the default
height.
* [me] Pie plots (both 2D and 3D) now displays the slice labels
by default.
 
* [me] Added two more Examples. barintex1.php shows how to use
integer scale and barscalecallbackex1.php shows how to use
a callback function for formatting the scale.
 
* [me] Modified grace calculation for Integer scale to have higher
sensitivity.
 
* [me] Restructured code so class DateLocale is now in jpgraph.php
rather than in jpgraph_gantt.php. Also added $gDateLocale as a
global instance of the class DateLocale
 
* [me] Modified integer autoscale to correctly handle very small values
(needs special handling of max==1 to avoid fraction)
 
* [me] Changed the way min value is extracted when finding the baseline
for bar plots. Now uses the function Scale::GetMinVal() instead of
reading the value directly fomr the instance variable. This makes it
work better with logscales so that the bar starts from the min value
of the log scale. Also added check in bar PreStrokeAdjust() to see if
we are using a log Y-scale to automatically adjust the Y-base.
 
* [me] Optimized Stroke() loop for LinePlot so calls to PlotMark::Stroke()
will only be done if the marks are really to be shown.
 
* [me] Added Axis::SetLabelAlign().
 
* [me] Made some internal modifiaction on how Axis title gets aligned
to make it possible to specify it manually without having it
automtically set. This makes it possible to generate nice
horizontal bar graphs.
* [me] Added three examples in the Example directory on how to make
horizontal bar graphs.
* [me] Don't always set Y-axis position automtically
 
* [me] Add Text::SetAngle() as synonym for SetOrientation()
Added SetLabelSide() as synonym for SetlabelPos()
 
* [me ]Make it possible to manually specify the alignment of the textstring
for the title position. This makes title looks nicer with horizontal
bar graphs.
 
* [me] Allow Y-axis labels to be at an angle
 
[14-May-2002] JpGraph 1.6.3
===========================
Changes/Additions:
* [me] Added functionality to make AccBarPlot::SetAbsWidth() work in
jpgraph_bar.phps
 
* [me] LinePlot::SetColor() no longer sets the color of the plotmark.
The problem that some people had was that if you set the mark color
specifically first and then unsuspecting called SetColor() for the
line the color for the plotmark circumference would also be set making
it look like the PlotMark::SetColor() didn't work.
 
* [me] Improved the functionality of GanntGraph::SetDateRange() to make
it possible to display a section of the graph.
(In previous version it was a checked error if you tried to plot
a graph where any activity bar was outside the specified area.
This is now changed to only cap the bars to the area.
This makes it more suitable to handle big gantt charts
which now can be split into several images to show different
parts of the projects)
 
* [me] Added GanttScale::SetWeekStart() to set the start of week to an
arbitrary day. For example SetWeekStart(0) will make the weeks start
on Sunday, SetWeekStart(1), Monday and so on.
 
* [me] Fixed a rounding error in Gantt chart that could cause the week
start day to off by one.
 
* [me] Modified the Min() and Max() methods for AccLineBar's to avoid
them overestimating the max value. (Basically now using the same
methods as in AccBarPlot)
 
* [me] Added missing code to do percentage calculation for 3D Pies so
they work the same way as the 2D Pies.
 
* [me] Added error check for the case where the image is so small that
the available plot area becomes to small.
 
* [me] Compensate for a PHP bug (#12474) in strtotime() which can affect
Gantt chart so that the same month name is shown twice.
See http://bugs.php.net/bug.php?id=12474
* [me] Compensate for the documented shortcomming in my
3D Pie algortitm whereby a small exploded slice close to 270 degrees
get's slighthly nagged at tha base due to the fact that the z-order
stroking algorithm is only perfect if the slices are not exploded.
 
 
[20-April-2002] JpGraph 1.6.2
=============================
Changes/Additions:
* [me] Slightly adjusted LinearTicks::Stroke() to better handle som
potential rounding problems.
 
* [Thomas George] Added LinePlot::AddArea() which makes it possible
to just fill part of a line plot (a part that is specified with a
start and end x-point)
 
* [Thomas George] Fixed bug with missing coordinate when using filled
line plot with step style.
 
* [me] Added client side image maps to scatter and line plots
 
* [me] Fixed problem with warning "IMG_ARC_CIRCLE not defined" when
running on GD 1.x
* [me] Removed test with is_null() in jpgraph.php to make JpGraph 1.6.2
work with older versions of PHP (especially 4.02).
 
[07-April-2002] JpGraph 1.6.1
=============================
Changes/Additions:
* [me] Modified autoscaling for the case where all values are equal to
make the min/max difference larger.
 
* [me] Fixed bug in 3D pies for certain data values
 
* [me] Fixed bug with images maps assuming that slices
where order anti-clockwise and the new pie algorithm did them
clockwise.
 
* [me] Added subtitle to Pie and Pie3D graphs.
 
[02-April-2002] JpGraph 1.6
===========================
Changes/Additions:
* [me] Changed license to QPL
 
* [me] Completely rewritten algorithm for 3D pies which gives MUCH better result. Will
also allow exploded 3D pies.
 
* [D. Reinbach] Better handling of filling line plot with negative
values
 
* [me] Added LinePlot::StrokeDataValue() for easy handling of plotting
data point values.
* [Gyozo Papp,me] Real locales for Gantt chart. The locales now take a
proper locale string (e.g. "en_UK", or "sv_SE") to get the real
locales from the system. Note that this breaks the sc compatibility
 
* [me] Removed jpgraph_dir.php and moved the directory settings back in
jpgraph.php due to problems in PHP with nested includes and search
paths.
 
* [me] Added possibility to show values for scatter plot by
refactoring value support back into jpgraph.php Plot() class. This
makes it easy for all subclasses that uses Plot() to add display
value support.
 
* [me] Added possibility to use X-coordinates in Error plots
 
* [me] Fixed missing LogScale::SetXLabelOffset(). This made it
impossible to use linear plots with a log x-scale !!!
 
* [me] Fixed bug so possible Y2 plots are also taken into account when auto
scaling the X-axis. This could otherwise couse plots outside the
scale when using Y and Y2 plots where Y2 plots had more data values.
* [me] **********!!SC BREAK!!**************
Aligned the way values are displayed on Bar graphs with line and
scatter plots. The values to be displayed for these plots are now
all accessed through the "value" property of the plot. For example
$myBarPlot->value->Show();
instead of the previous
$myBarPlot->ShowValue();
 
* [me] **********!!SC BREAK!!**************
Aligned the way values are displayed in Pie plots with line and
bar plots. You know use the "value" property in exactly the same way
as in bars and lines.
 
* [me] **********!!SC BREAK!!**************
Aligned the way values are displayed in 3D Pie plots with line and
bar plots. You know use the "value" property in exactly the same way
as in bars and lines.
 
* [me] Added possibility to display individual values in an
accumulated bar graph in addition to the overall accumulated
value. This is done as usual through setting the individual bars
value property to what you want (size, color, format and so on)
 
* [me] Added another default error handler which is image based to
make it easier to see error messages when images are included
in a page. This is now the default error handler.
 
* [me] Added possibility to specify the location of the X-Axis
to the top of the graph by using xaxis->SetPos("max") also
added new Example topxaxisex1.php to demonstrate this feature.
 
* [me] Added more 3D pie examples to demonstrate new functionlity.
 
[01-March-2002] JpGraph 1.5.3
=============================
Changes/Additions:
* [me] Make it possible to use JpGraph 1.5.3 with GD 1.8.x. In 1.5.2 I was
using a function only available in GD 2.x.
 
[29-Feb-2002] JpGraph 1.5.2
===========================
 
Bug fixes:
----------
* [me] Released the correct 3D pie file (By mistake I mixed the stable version with
the development branch for 2.0 in the 1.5.1 release just to prove
that I'm still human :-)
 
* [me] Fixed out of bounds error when using shadows for bar graphs
with 0 value
 
* [me] Fixed typo in DisplayValue::SetFormat()
 
* [me] Fixed potential array out of bounds error in Plot::Min() and
Plot::Max()
 
* [me] Fixed misplaced ')' in string construction in call to
JpGraph error.
 
Changes/Additions:
------------------
* [me] Added possibility to use "auto" file name when stroking
directly to a file.
 
 
* [me] Added tag 'title' to the image maps to make for better
compatibility with Mozilla.
 
* [me] Moved class LineProprty to jpgraph.php from jpgraph_gantt.php
since it can be used in other modules as well.
 
* [me]Added Text::GetTextHeight() which differs from
Text::GetFontHeight() in that it takes the total text height
(possible multiple lines) into account.
 
* [me] Added Image::FilledArc()
 
* [me] Added RotImage::SetTranslation()
Added RotImage::Circle()
Added RotImage::FilledCircle()
Added RotImage::Arc()
Added RotImage::FilledArc()
 
 
[11-Feb-2002] JpGraph 1.5.1
===========================
* [me] No longer treat a not set $y[0] value as an explicit error. Instead
silently set $y[0] to 0.
 
* [me] Changed "include" to "require" in jpgraph.php when including
jpgraph_dir.php. This seems to fix the strange problem whereby
the constants defined in jpgraph_dir.php didn't have a correct
value in jpgraph.php.
 
* [me] Fixed problem with correctly drawing of bars when all bars
are negative. (Previously the baseline wasn't correctly handled
since min/max values needs to be mirrored for negative bars)
Note: Funny this problem has gone unnoticed so long.
 
* [me] Fixed problem with doing gradient fill for negative bars.
 
* [me] Fixed problem with autoscaling when there is a very small
difference (< 0.00001) between min and max and when both min and max are
negative. This might happen if you have a single negative value.
 
* [me] Added labels for line graph. Each point my now also optionally
display it's value on a line graph. Value are controlled trough
class DisplayValue and it's instance in LinePlot.
LinePlot->value->Show(),
LinePlot->value->SetColor(),
LinePlot->value->SetFont(),
LinePlot->value->SetMargin(),
LinePlot->value->SetFormat(),
[27-Jan-2002] JpGraph 1.5
=========================
* [me] Fixed misnamed xmin variable in Min() for acc bars
 
* [me] Added possibility to specify paragraph alignment for
multi line text, i.e the text can be left,right or center aligned
within it's bounded box. The lignment is set by the new method
Text::ParagraphAlign()
 
* [me] Changed position specification for text so that if the position
is specified in range [0,1] it is interpreted as fraction of image
height width and otherwise as absolute pixels.
 
* [me] Added possibility to specify pie size (radius) both as a fraction and
absolute size in pixels.
 
* [me] Added possibility to tweak color specification by adding a
saturation percentage, i.e you can specify color as "red:0.65"
which means 65% of the red value (in other words 35% darker).
 
* [me] Tweaked the estimation of number of segments to approximate an
arc in Image::CakeSlice.
 
[17-Jan-2002] JpGraph 1.5beta2a
===============================
* [me] Fixed typo in Max() calculation for accumulated bar graphs
which caused it to return wrong value.
 
* [me] For Min() calculation for acc bars graphs take the user
specified ymin into account.
 
* [Peter Svistunov, me] Added Cyrillic unicode support through the
global define LANGUAGE_CYRILLIC. This is also the start of a
generic support for Unicode languages through the LanguageConv
class.
 
 
[15-Jan-2002] JpGraph 1.5beta2
==============================
* [me] Rewrite of the pie-chart drawing algorithm. This version
is slightly slower but avoids using GD floodfill function. This
fixes problems with small slices not being filled completely. As
an added bonus it is now possible to explode (and specify the
explode radius) for all slices. It is also possible to draw the
pie without having internal borders between the slices as well
as turning on/off the border surronding the pie.
 
* [me] Added graphic primitive CakeSlice() to the Image class.
Used to simplify pie-drawing.
 
* [me] Added more generic error handling. It is now possible to
install your own error object with
JpGraphError::Install(<name of error object>)
The default error handler will just abort execution.
 
* [me] Security whole in utility script for displaying source
and image in frames fixed.
 
* [Cedric Scheyder] Actively ignore hours in calculating Max/Min
values for dates in Gantt charts to avoid problems in autoscaling
when users specify start and end dates down to hours.
 
* [Rick Widmer] Fixed problem in calculating min/max value when first
Y-value was non-numeric.
* [me] Fixed calculation of width and height of text with multiple lines.
Multiple text lines (text blocks) should now be almost fully supported.
 
 
[16-Dec-2001] JpGraph 1.5-BETA
==============================
* Take "\n" into (some) account when calculating string height and width
Text output now supports multiple lines better.
 
* [me] Removed reference to global PHP_SELF, use HTTP_SERVER_VARS array
instead. This makes JpGraph working with 'register_globals' turned
off.
 
* [me] Added some rudimentary check that GD is enabled before trying to
run JpGraph.
 
* [me] Fixed silly cut-and-paste bug in AccBarPlot::Max() which could
cause to small max values to be returned
 
* [me] Added property 'title' to PlotMark. The title is printed in the center
of the plotmark.
 
* [DanNY (dulcis28@hotmail.com)] Added JpGraph Logo. (Thanks!)
 
* [me] Added jplintphp.php, jpgendoc.php, jplintdriver.php which are
parsing, documentation and pretty printing tools I use to help
me to documentation and find unused code.
Tthat does some simple static analysis on PHP for silly mistakes
that I do (Like using instance variables without qualifying them
with "$this->" ) The tool also warns about unused instance variables.
Since it also parses the classes and methods I use it to generate
the documentation skeleton for the reference section.
 
* [me] Added Gantt chart funcionality, jpgraph_gantt.php . See
Gantt tutorial for help on usage.
 
* [me] Added new Gantt tutorial
 
* [me] Added BKIMG_CENTER, possibility to center the background image.
 
* [me] Timeout function now also aplies when you generate an image
off-line, i.e if the imagefile exist and is within the time window
now file will be written.
* [Rasmus Lerdorf] Added patch to make background images work with GD 2.x
N.B GD 2.01 has bugs in handling TTF font with truecolor images which
are fixed in 2.02 but that has (of this writing) still not been officially
released. GD 2.x support in JpGraph is still to be considered experimental.
 
* [me] Fixed some potential rounding errors in 2D Pie plot which in some
circumstances might have caused a flood fill to escape. Also added check
to better handle very small slices so we don't try to do a fill
on the border edge.
 
* [me] Slightly changed the internal design for band patterns.
They are now created by a factory class instead. This makes it much easier
to re-use and have maximum code reuse.
 
* [me] Factored out some functionlity from Graph::Stroke() to make it possible
to re-use some code in GanttGraph::Stroke()
 
* [me] One more instance when PHP surprised me by thinking 0 == "-" aarrghhh
Now I think (knock on wood) all problems with data points=0 should be solved
 
* [me] Added '&' to the assignment in Graph::Add() This now lets you specify changes
for lines, plots even after they been added to a Graph. But I'm not sure if this
is really such a good ide because you will have problem if you write code
like
for( .... ) {
$myplot = new LinePlot(.....);
$graph->Add($myplot);
}
Since this will not work the way you think (why?) Because the same
reference to the variable $myplot will be used for all additions and
hence the graph will only have multiple instances of the last added
LinePlot(). Have to think of this and what is the best way. (I will
probably never get used to PHP references....)
 
 
[11-Nov-2001] JpGraph 1.4
==========================
Bug Fixes:
-------------------------------------------------------------------------------------
* [me] Enabled E_NOTICE warnings in my PHP installation and found a couple of
glitches (harmeless out-of-bound in two loops) which is now corrected.
* [me] Fixed problem in line plots where y-value==0 wasn't drawn. (Once again
bitten by the fact that in PHP the following is true: ""==0)
* [me] Fixed color specification for bars when initialized as an array of colors
* [me] Fixed color of bars using shadow which was advertedly set to shadow color
* [me] Fixing incorrect color specification for legends using bars with color arrays
* [me] Add check for sum=0 in pie plots to avoid divide by 0 problem
* [me] Changed the stroke orderd for FilledRectangle() so that the shadow doesn't
overwrite a line with weight > 1
* [me] Fixed incorrect calculation of font height for titles which cause the
subtitle to be to close to the title.
 
Additions:
-------------------------------------------------------------------------------------
* [me] Added depth parameter (DEPTH_FRONT, DEPTH_BACK) for gridlines
Graph::SetGridDepth()
 
* [me] Added possibility to add static horizontal and vertical band with a
pattern in the plot area. Graph::AddBand() Supports solid, diagonal,
stright line, 3D-plane crosses (both diagonal/vertical) patterns.
Graph::AddBand()
* [me] Added possibility to have static lines in the plot. This is now implemented
with new class PlotLine and two new functions Graph::AddLine(),
* [me] Added symbolic constants to specify background image types
BGIMG_COPY, BGIMG_FILLPLOT, BGIMG_FILLFRAME
 
* [me] Added extended label formatting through either
Axis::SetLabelFormatString() C-style formatting string
or
Axis::SetLabelFormatCallback() A callback function that are given the value to be displayed
and should manipulate the value as it likes
The use of the old style digit precision variable will be deprecated from next version.
 
* [me] Added error check if supplied Y-data has unspecified value at index 0 to avoid
out of bounds error when corrupted data is sent in to JpGraph.
* [me] Added possibility to specify image depth for gridlines. You can now specify
Graph::SetGridDepth() as DEPTH_FRONT or DEPTH_BACK. Depending on if you want
the gridlines at the back of in front of your plots.
 
* [me] Added possibility to specify Cache file name as "auto". In this case the
image file name will have the same name as the scriupt that generates the
image with the extension of the automtically generated graphic format.
NOTE: You will get the wrong extension using this feature at the same
time as specifying a different graphic format thne the automatically choosen
one.
 
* [me] Added some more advanced examples for impuls drawings impulsex3.php and
impulsex4.php
 
* [me] The values on top of bars can now be at an angle and the horisontal
position now account for if a shadow is present.
* [me] Added filename to Graph::Stroke() which makes it easy to output an image
directly to a file _without_ streaming it back to the browser. Usefull for
batch processing
* [me] Added new tutorial for bar graphs
 
* [me] New scale type "int". This gives a normal linear scale but restricts
ticks (and labels) to integer values. Can be used for both X and Y scales.
 
* [me] Added subtitle to graph
 
* [me] Added possibility to specify an array of X-coordinates with bar plots to
position individual bars on the X-scale. Makes it much easier to combine
bar plots with other types of plots, (line, scatter etc)
* [me] Extended utility adjimage.php to allow it to manipulate color saturation.
 
* [me] Added Image::AdjSat() to allow manipulation of the color
saturation in the image. This also makes it very easy to change the image
to greyscale (just set saturation=-1).
Extended Graph::AdjImage() and Graph::AdjBackgroundImage()
to include new parameter for saturation value.
* [me] Added BarPlot::SetAlign() which makes it possible to align
bars relative the tickmark for linear and int scale
* [me] Added possibility to absolutely set the width of bars. This will
override the automatically decided with based on the scale and tick distance
Changes:
-------------------------------------------------------------------------------------
* [me] Legend color for scatter plots now becomes the fill color of the mark
 
* [me] Impulsplots now anchors at Y-value = 0 if the y-axis contains both negative
and positive values. Otherwise it will go to the lowest value on the Y-axis.
 
* [me] Bar shadows is now connected to bars to make for a stronger 3D effect.
 
* [me] Removed all deprecated references and usage of FONT0, FONT1, FONT2. Note
You can no longer use these. Instead use FF_FONT0, FF_FONT1, FF_FONT2 etc
* [me] Text scale now starts default labelling at 0
 
* [me] All plots internally adjusted to start at default X-coordinate 0 to harmonize better
with X-scale.
 
* [me] Graph->Stroke() now just returns instead of exit()
 
* [me] Removed flag argument for BarPlot::SetShadow()
 
* [me] Bar plots are know by default filled with lightblue
unless otherwise specified.
* [me] Changed the way bars are positioned for linear and integer
scale for maximum flexibility when mixing barplot with other
plots.
* [me] The ALT strings for all image maps now uses printf() syntax to display
the actual value. If you have used this feature you must update your
ALT strings, for example "val=%v" must become "val=%d" or whatever format
you choose.
* [me] Changed the formatting of bar graphs by changing the framework
so that labels on the x-axis using a text scale is now independent
on the tick marks.
This makes it possible to have the labels centered under each bar but have
the tickmarks between the bars as most other commercial graph packages
format these typw of graphs. Introduced Axis::SetTextLabelsInterval()
Effects jpgraph.php, jpgraph_log.php and jpgraph_bar.php
* [me] Renamed Axis::SetTextTicks() to Axis::SetTextTicksInterval() to make the name
more descriptive. The old name is deprecated from this version on but will still
work until 2.0 to keep compatibility.
* [me] Cleaned up implementation of pie3d so it now inherits from pie to avoid
a lot of duplicated code and easier maintainance. (A good example of the real
life OO programming where you might not see the similarities between two classes
until you fully implement them.) File size of jpgraph_pie3d.php has shrunk by
roughly 40%
[23-Sep-2001] JpGraph 1.3.1
===========================
Additions:
* [Michael Anthon] Added client side image maps to 3D pie plots
* [me] Added possibility to better control the labeling of pie graphs with an optional
label formatting string PiePlot::SetLabelFormat(), PiePlot::SetLabelType()
This also makes it possible to have labels with the absolute value and not only the
percentage. (same with pie3d)
* [me] Added formatting capabilities for legends on pie and pie3d graphs. Can have the value
automtically included (Se Examples/pieex6.php)
* [me] Added some more examples, negbarvalueex1.php, scatterlinkex2.php, pie3d_csimex1.php
pieex6.php
 
Known bugs and omissions:
- Client side image maps does not currently handle exploded pie graphs (just
normal pie graphs.
 
Bug fixes:
* [me] Fixed problem with positioning the displayed values for negative bars
* [me] Fixed shadow for negative bars
* [me] Fixed problem in Plot::Min(), PlotMax::Max() whereby zeros where not counted
towards minimum since in PHP 0=="". This could sometimes cause strange autoscaling.
* [Vitaly E. Ashmarin] Wrong arguments to imagejpeg() for combination of specified
image quality and filename = ""
* [John Milne] BarPlot::SetFillColor() fixed glitch in loop variable
 
 
[13-Sep-2001] JpGraph 1.3
=========================
Note: I have to the best of my memory tried to give credit where
credit is due. Howevever, since ver 1.2.2 I have received over 2000 mail about
JpGraph with Questions/Suggestions/Improvments (and a few bug fixes) etc and
I might have missed some in the process of going through these mails. The
fault is completely my own and if you recognize some idea I have implemented
something which you think you should have credit for please drop me a note and
I will adjust the add you to the change notes.
 
Known bugs and omissions:
- The automatic value on bar graphs does not work well with
negative bar graphs. (Quite easy to fix though..)
- Client side image maps does not currently handle exploded pie graphs (just
normal pie graphs.
 
IMPORTANT NOTICE:
* SC (SOURCE COMPATIBILITY) BREAK !: If you want to rotate the image the parameter
is no longer supplied directly in the call to Graph() but rather as a method
call Graph::SetAngle(). I decided to make this SC break since I judged it more
natural to supply the timeout value just efter the specified cache-file name
in the Graph() call. Hopefully this will not hit to many people since my hunch is
that few people uses the rotate function and it's very easy to fix those script
that does so.
 
Bug Fixes:
* [michael@anthon.net] Corrected behviour of accumulated bar graph so it now
diffrentiate between the accumulated positive and negative values.
* [marko@fly.srk.fer.hr] Fixed Max() calculations for accumulated bar graphs
where my original code was a little bit sloppy. (I simply took the max for
each plot and added those and this might be more then the real maximum.)
* [m.purgar@extracom.de] Spotting an incorrect "jpg" in the image where it should
have been "jpeg"
* [adam.blomberg@euroseek.net,patrik.johansson@euroseek.net] 3D-Pie filling
problem for small slices due to the discrapency between GD arc() and the
JpGraphs purely mathematical definition of an ellipse.
* [delorme.maxime@free.fr] 2D-Pie Floodfill might "escape" for very small values of slices.
 
* [et.al] Improved handling of 0:s vs "" values. This was necessary since PHP treats
0 as "" the same in a number of situations and JpGraph needs to diffrentiate these
two cases. This caused 0 data values to be treated as null values and not be inluded
in (for example) autoscaling consideration.
 
Additions:
* [me] Added new global constant USE_CACHE which makes it possible to disable
writing to the cache even if a filename is supplied in th Graph::Graph() method.
 
* [me] Added LinePlot::SetStyle() to make it possible to make dashed, dotted etc
lineplots. (See example1.2). Also adjusted legend to display the same style in
the legend.
* [michael@anthon.net, me] Added client side image maps for all types of bars
and 2D pies with possibility to have the actual value shown in an ALT-tag.
* [me] Added drop shadow (or rather "right-up" shadow) to bar graphs BarPlot::SetShadow()
 
* [me] Added possibility to have the actual value of bar graphs displayed at top of graphs
via BarPlot::ShowValue(), BarPlot::SetValueFont(), SetValueMargin(), SetValueColor()
The format of the value is specified according to standard C printf() string formatting
i.e. "val=%d" will for example print a string "val=13"
* [me] Added possibility to adjust brightness and contrast for background image
via the Graph::AdjBackgroundImage() method.
* [me] Added possibility to adjust brightness and contrast in the finished image
via the Image::AdjBrightContrast() method.
* [me] Added possibility to just generate an image to a file and not stream
it directly back to the browser. Added parameter $aInline to Graph::Graph()
* [me] Added timout for cache, i.e if the image in the cache is older then
the specified number of minutes (=0 never re-generate, -1 always regenerate)
then re-generate the image. Just specify a timeout in minutes with a call:
$mygraph->cache->SetTimeOut(10)
* [me] Added possibility to use logarithmic scale for SpiderPlots. This also resulted
in a little bit of internal cleanup in jpgraph_spider.php.
* [me] Added SetWeight() method to class Ticks() for control of line thickness for ticks
 
* [me] Added SetMarkColor method to class TIcks() which lets you specify different
colors for major and minor tick marks.
* [me] Added method RelTranslate() to LinearScale() and LogScale() classes which is used
in Spider class. This makes a world to screen relative translation.
* [me] Added possibility to link data points in a scatter plot with lines
by the addition of method ScatterPlot::SetLinkPoints()
* [me,john.milne@one2one.co.uk] Added possibility to have individual colors of
bars in bar graphs by having BarPlot::SetColor() accept an array as argument.
* [sergio@alsernet.es] Make it possibly to have x-tick labels to consist of two lines
by inserting a "\n" separator in the text.
* [CK1@wwwtech.de] Adding JPEG quality setting. This is done by adding
a method SetQuality() to the img class. After creating a graph this can then
be used as $mygraph->img->SetQuality($some_qvalue).
Currently this only affects JPEG images.
* [delorme.maxime@free.fr] Possibility to use different grace value for top and bottom
of graph and not just a single value as in 1.2.2
 
Changes:
* [me] Changed group/permission handling for created files to better adjust itself
to the way the local Apache user is setup
* [me] The default for spider graphs is now NOT to be filled
 
* [me] Allow all datapoints to be 0 which will set the scale to [0,1]
 
* [me] Removed the need for a DIR_BASE variable
 
[29-Apr-2001] JpGraph 1.2.2
===========================
Bug fixes:
* Removed reference to non-existent property 'bypass' in class RotImg
* Changed to allow the last X-gridline to be drawn (comparison with limit was '<'
where it should have been '<=' )
 
Additions:
* Added possibility to use background image
* Added possibility to use approximate color through the "USE_APPROX_COLORS"
constant
* Handling of diffrent form of "null values" for line graphs. An y-value
can now be "" or "-". In the first case (a true null value) this mark
will cause a disruption in the line graph to indicate that the value
is undefined. In the other case specifying the value as "-" will cause
the value to be ignored bu the line will still be drawn between the
previous data point and the following. Neither of these cases will have
any mark drawn.
* Added a fatal warning when no more colors can be allocated for the chosen
graphic format.
 
Changes:
* "Downgraded" anti-aliasing algorithm to use fewer color levels
in the transition to avoid using up to much of the color palette
* Cleaned up some of the code to not rely on PHP default initialization
of variables. This will help those who have got warnings when they
have had all error reporting enabled in php.ini (E_ALL)
* Legends now show the plot mark (if defined) instead of just a square of
the right color.
 
Acknowledgements:
* Thanks to kevin@pricetrak.com for suggesting the treatment of
pure NULL values.
* Thanks to luca_n@hotmail.com for getting my attention to the warnings
caused by relying on PHP default initialization of variables.
(My installation had E_NOTICE disabled, hence I never got those warning myself.)
 
 
[29-Mar-2001] JpGraph 1.2.1
===========================
Bug fixes:
* When min and max values for autoscaling was equal this resulted in trying to calculate
log10(0) = INF resulting in an infinite loop in LinearTicks::Stroke()
* When autoscaling was used with only one data point it tried to calculate log10(0) = INF
resulting in an infinite loop
* fopen("xxx","r") should be fopen("xxx","rb") causes problems on windows system with IIS5
* JPG streaming function was incorrectly called "imagejpg" should be "imagejpeg" (see the difference?)
* Non existent color name in jpgraph_pie.php
* Removed all deprecated forced references in function calls
* The width of the surrunding box was not calculated correctly for internal bold font
 
Additions:
* Color themes for pie graphs
* Beta release of 3D pie graphs
* Added DIR_BASE as constant to make it possible to use one system wide copy
of JpGraph. NOTE: This must be set to the directory where JpGraph is installed.
 
Acknowledgements:
* (ck1@wwwtech.de) (and a russian guy which I unfortunately lost the name of)
for reporting the imagejpg spelling mistake
* (ales.gregor@zps.skoda-auto.cz) for finding the binary file problem with IIS
* Several people have reported the problem with autoscaling when all Y-values
were equal. Thanks to you all for acting as my privet QA team!
 
 
[18-Mar-2001] JpGraph 1.2
=========================
Additions:
----------
* Added "BRAND_TIMING" which give possibility to brand each image generated with
the time (in ms) it took to generate the image.
* Added Gradient Fill for bar graphs, The gradient fill allows 6 different styles.
* Added Anti-aliasing for lines. Note drawing anti-aliased lines is 7-10 times
slower then "normal" lines!
* Added full TTF support. this means an internal SC break (Source Code Break). Normal JpGraph
script should not be affected if you have used only publized "public" frunctions. The SC break is
to allow uniform treatment of both internal fonts and TTF. This has been achieved by changing
the parameter list for SetFont(). However, backward compatibility with the old naming conventions
for internal fonts are kepot, e.g. SetFont(FONT1_BOLD) still works but is deprecated and will not
be valid from 2.0
* Added possibility to control font for title of Spider Axis through the added
property 'title' to the axis in the spider graph.
* Added 'SetColor()' in pie graphs as a shortcut to SetMarginColor() to set the background color
* Added possibility to draw X-axis labels at arbitrary angle. Internal fonts only supports
horizontal and verical.
* Added possibility to draw boxed text at an angle
* Added possibility to have different colors for axis and the labels on the axis by the addition
of extra parameter to SetColor()
* Added 350 more named colors.
* Added canvas "fake" graph to make it easy to draw arbitrary graphics
* Added SetCenter() method for line graphs.
* Added SetGrace() for autoscaling purposes.
 
Changes:
--------
* If you use a text-scale for X-axis the default labels now start at 1 instead of 0 since this is
actually a counting scale and it makes more sense to start at 1.
* Improved handling of bar-graphs with negative values.
* Updated existing examples to use new format for SetFont()
* Made it a critical error to specify a non existant font
* Changed so that orientation for Text() is now given as an angle, i.e. SetOrientation(45). Old
style of using SetOrientation("v") (for vertical) is deprecated. But will work until V2
 
Bug fixes:
----------
* Improved handling of computational effects on small values in scaling where a rounding error might cause the
last label not to be drawn.
* The position for the title of X-axis could in some cases be slightly different in first
and second pass due to incorrectly determination of the X-axis labels font height.
* Specifying an minimum Y-value for Y-axis on bar graphs could on rare occasions (combination
of scale values and specified density of autoscaling ticks) cause a gap between the bottom of
each bar and the X-axis.
 
 
[18-Feb-2001] JpGraph 1.1
=========================
Additions/Changes:
------------------
* Added Spider graphs
* Added Pie graph
* Added Scatter (and impuls) graphs
* Added possibility to rotate plots an arbitrary angle
* Added step style rendering to lineplot
* Added Breseham circle drawing which gives better visual apperance
then the built in Arc() in GD (on the expense of CPU and performance)
* Improved Polygon and Rectangle drawing so that it will use line weight settings
* Improved the visual appearance of lines with weight>1 by correctly calculating
(angle wise) the endpoints and using a filled polygon to draw the line.
Unfortunately it would require some real improvements in the GD library to really improve
the visual appeance of lines with weight>1. This is as good as it gets without writing
a low level pixe-by-pixel correct plotting. With my method you get it to look visually
aestethic right in 90% of the cases with just 10% work.
* Added MARK_FILLEDCIRCLE as new mark type. Note that due too the poor performance of the
basic Arc() image primitive in PHP4 the circles isn't perfect circles, they tend to be a
a little bit flat at multiples on PI/2.
* Added the possibility to have a separate fill- and line- color for marks
* Moved Class PlotMark from jpgraph_line.php to base in jpgraph.php since this class is also used
with scatter plots.
* Made it a critical error to try to use Text X-scale with specified X-data points.
Previously no warning was given for this non-defined state. (Using text scale with specified
points really doesn't make sense.)
* Made it a critical error to use unknown color rather than silently replacing it with black.
* Updated documentation to reflect added capability
 
 
Bug fixes:
----------
* Fixed minor bug in Line() in which it didn't update the last point for use with
subsequent LineTo() calls (forgotten $this->)
* Eliminated assumptions in DashedLine() that x1<=x2 and y1<=y2 eliminates the
potential pixel overshoot.
* Fixed a serious bug in Line plot when used with a specified X-scale (not the normal default)
since the X-coordinate wasn't read from the correct vector!
* Fixed a serious bug whe using as specified X-scale since the maximum value for a plot
wasn't correctly passed to the autoscaling.
Note: The reason that these two bugs haven't been discovered previously is the fact
that my test specs didn't include test cases to do with specified X-axis (I almost never ever use that).
This has now been corrected and added to the test suit.
* Fixed so the possible box around the plot area correctly honours the weight specified for it.
 
 
[05-Feb-2001] JpGraph 1.0
=========================
* Initial release.

// As usual the algorithm get more complicated than I originally
// envisioned. I believe that this is as simple as it is possible
// to do it with the features I want. It's a good exercise to start
// thinking on how to do this to convince your self that all this
// is really needed for the general case.
//
// The algorithm two draw 3D pies without "real 3D" is done in
// two steps.
// First imagine the pie cut in half through a thought line between
// 12'a clock and 6'a clock. It now easy to imagine that we can plot
// the individual slices for each half by starting with the topmost
// pie slice and continue down to 6'a clock.
//
// In the algortithm this is done in three principal steps
// Step 1. Do the knife cut to ensure by splitting slices that extends
// over the cut line. This is done by splitting the original slices into
// upto 3 subslices.
// Step 2. Find the top slice for each half
// Step 3. Draw the slices from top to bottom
//
// The thing that slightly complicates this scheme with all the
// angle comparisons below is that we can have an arbitrary start
// angle so we must take into account the different equivalence classes.
// For the same reason we must walk through the angle array in a
// modulo fashion.
//
// Limitations of algorithm:
// * A small exploded slice which crosses the 270 degree point
// will get slightly nagged close to the center due to the fact that
// we print the slices in Z-order and that the slice left part
// get printed first and might get slightly nagged by a larger
// slice on the right side just before the right part of the small
// slice. Not a major problem though.

FPDF est constitué des éléments suivants :
 
- le fichier principal fpdf.php contenant la classe
- les fichiers de métrique des polices (contenus dans le répertoire font de cette archive)
 
Les fichiers de métrique sont indispensables dès que l'on veut écrire du texte dans un document.
Ils peuvent se trouver en trois endroits différents :
 
- dans le répertoire courant (celui du script en cours d'exécution)
- dans un des répertoires définis par le paramètre include_path
- dans le répertoire défini par la constante FPDF_FONTPATH
 
Voici un exemple pour le dernier cas (notez le slash final obligatoire) :
 
define('FPDF_FONTPATH','/home/www/font/');
require('fpdf.php');
 
Si ces fichiers ne sont pas accessibles, la méthode SetFont() produira l'erreur suivante :
 
FPDF error: Could not include font metric file
 
Vérifiez alors que vous avez correctement défini la constante.
 
Remarques :
 
- Vous pouvez aussi définir FPDF_FONTPATH directement au début de fpdf.php
- Seuls les fichiers correspondant aux polices effectivement utilisées sont nécessaires
 
Les tutoriels fournis dans l'archive sont prêts à être exécutés.

<H2>Historique</H2>
<B>v1.51</B> (03/08/2002)
<BLOCKQUOTE>
- Support des polices Type1.<BR>
- Ajout des encodages pour les pays baltes.<BR>
- La classe travaille maintenant en interne en points avec l'origine en bas afin d'éviter deux bugs avec Acrobat 5 :<BR>&nbsp;&nbsp;* L'épaisseur des traits était trop importante lors des impressions sous Windows 98 SE et ME.<BR>&nbsp;&nbsp;* Les polices TrueType n'apparaissaient pas immédiatement avec le plug-in, il fallait provoquer un rafraîchissement de la fenêtre pour les voir apparaître.<BR>
- Il n'est plus nécessaire que le séparateur décimal soit le point pour générer des documents valides.<BR>
- La zone cliquable dans une cellule était toujours positionnée à gauche indépendamment de l'alignement du texte.<BR>
- Les images JPEG en mode CMYK apparaissaient en couleurs inversées.<BR>
- Les images PNG transparentes en niveaux de gris ou couleurs vraies étaient incorrectement traitées.<BR>
- L'ajout de nouvelles polices fonctionne maintenant correctement même avec l'option magic_quotes_runtime à on.<BR>
</BLOCKQUOTE>
<B>v1.5</B> (28/05/2002)
<BLOCKQUOTE>
- Support des polices TrueType (AddFont()) et des encodages (Europe de l'Ouest, de l'Est, cyrillique et grec).<BR>
- Ajout de la méthode Write().<BR>
- Ajout du style souligné.<BR>
- Support des liens internes et externes (AddLink(), SetLink(), Link()).<BR>
- Gestion de la marge droite et ajout des méthodes SetRightMargin() et SetTopMargin().<BR>
- Modification de SetDisplayMode() pour sélectionner un affichage continu ou en colonnes.<BR>
- Le paramètre border de MultiCell() permet de choisir les bords à tracer comme Cell().<BR>
- Lorsqu'un document ne contient aucune page, Close() appelle maintenant AddPage() au lieu de provoquer une erreur fatale.<BR>
</BLOCKQUOTE>
<B>v1.41</B> (13/03/2002)
<BLOCKQUOTE>
- Correction de SetDisplayMode() qui ne fonctionnait plus (le visualiseur PDF utilisait l'affichage par défaut).<BR>
</BLOCKQUOTE>
<B>v1.4</B> (02/03/2002)
<BLOCKQUOTE>
- PHP3 n'est plus supporté.<BR>
- Compression des pages (SetCompression()).<BR>
- Choix du format des pages et possibilité de changer l'orientation en cours de document.<BR>
- Ajout de la méthode AcceptPageBreak().<BR>
- Ajout de la méthode SetLeftMargin().<BR>
- Possibilité d'imprimer le nombre total de pages (AliasNbPages()).<BR>
- Choix des bords des cellules à tracer.<BR>
- Nouveau mode pour la méthode Cell() : la position courante se déplace sous la cellule.<BR>
- Possibilité d'inclure une image en n'indiquant que la hauteur (la largeur est déterminée automatiquement).<BR>
- Correction d'un bug : lorsqu'une ligne justifiée provoquait un saut de page, le pied de page héritait de l'espacement inter-mot correspondant.<BR>
</BLOCKQUOTE>
<B>v1.31</B> (12/01/2002)
<BLOCKQUOTE>
- Correction d'un bug dans le tracé du cadre avec MultiCell() : la dernière ligne partait toujours de la marge gauche.<BR>
- Suppression de l'en-tête HTTP Expires (pose des problèmes dans certains cas).<BR>
- Ajout de l'en-tête HTTP Content-disposition (semble aider dans certains cas).<BR>
</BLOCKQUOTE>
<B>v1.3</B> (03/12/2001)
<BLOCKQUOTE>
- Gestion des sauts de ligne avec justification du texte (MultiCell()).<BR>
- Ajout du support de la couleur (SetDrawColor(), SetFillColor(), SetTextColor()). Possibilité de dessiner des rectangles pleins et de colorer le fond des cellules.<BR>
- Une cellule dont la largeur est déclarée nulle s'étend jusqu'à la marge droite de la page.<BR>
- L'épaisseur des traits est maintenant conservée de page en page et vaut 0,2 mm par défaut.<BR>
- Ajout de la méthode SetXY().<BR>
- Correction d'un passage par référence effectué d'une manière obsolète en PHP4.<BR>
</BLOCKQUOTE>
<B>v1.2</B> (11/11/2001)
<BLOCKQUOTE>
- Ajout des fichiers de métrique des polices et de la méthode GetStringWidth().<BR>

</BLOCKQUOTE>
<B>v1.11</B> (20/10/2001)
<BLOCKQUOTE>
- L'utilisation des PNG ne nécessite plus PHP4 et l'extension Zlib. Les données sont intégrées directement dans le document PDF sans étape de décompression/recompression.<BR>
- L'insertion d'image fonctionne maintenant correctement même avec l'option magic_quotes_runtime à on.<BR>
</BLOCKQUOTE>
<B>v1.1</B> (07/10/2001)
<BLOCKQUOTE>
- Support des images JPEG et PNG.<BR>
</BLOCKQUOTE>
<B>v1.01</B> (03/10/2001)
<BLOCKQUOTE>
- Correction d'un bug lors du saut de page : dans le cas où la méthode Header() ne spécifiait pas de police, celle de la page précédente n'était pas restaurée et produisait un document incorrect.<BR>
</BLOCKQUOTE>
<B>v1.0</B> (17/09/2001)
<BLOCKQUOTE>
- Première version.<BR>

<A NAME='1'></A><B>1.</B> <FONT CLASS='st'>Quelle est exactement la licence de FPDF ? Y a-t-il des restrictions d'utilisation ?</FONT>
<P>FPDF est Freeware (c'est indiqué au début du fichier source). Il n'y a pas de restriction
d'usage. Vous pouvez l'incorporer librement dans votre application (commerciale ou non), avec
ou sans modification.</P>
<A NAME='2'></A><B>2.</B> <FONT CLASS='st'>Lorsque j'essaie de créer un PDF, plein de caractères bizarres s'affichent à l'écran.</FONT>
<P>Ces caractères "bizarres" sont en fait le contenu réel du PDF. Ce comportement est un bug d'IE.
Lorsqu'il reçoit d'abord une page HTML, puis un PDF à partir de la même URL, il l'affiche
directement sans lancer le plug-in Acrobat. Cela arrive fréquemment en cours de développement :
à la moindre erreur de script, une page HTML est envoyée, et après correction, le PDF arrive.
<BR>
Pour résoudre le problème, il suffit de fermer IE et de le relancer. On peut aussi aller sur
une autre URL et revenir.
<BR>
Pour éviter ce genre de désagrément durant le développement, on peut générer le PDF directement
dans un fichier et l'ouvrir via l'explorateur.</P>
<A NAME='3'></A><B>3.</B> <FONT CLASS='st'>J'essaie de générer un PDF et IE m'affiche une page blanche. Que se passe-t-il ?</FONT>
<P>Tout d'abord, vérifiez que vous n'envoyez rien au navigateur après le PDF (même pas un espace
ou un retour-chariot). Vous pouvez mettre un exit juste après l'appel à la méthode Output()
pour en être sûr.
<BR>
Si ce n'est pas ça, c'est que vous êtes victime du syndrome de la "page blanche". IE utilisé
en conjonction avec le plug-in Acrobat souffre de très nombreux bugs, quelles que soient les
versions. Essayez de tester votre application avec le plus de versions d'IE possible (en tout cas
si elle est sur Internet). Le problème survient surtout lorsqu'on utilise la méthode POST, c'est
pourquoi il est fortement déconseillé de l'utiliser (d'autant qu'elle pose d'autres problèmes,
voir la question suivante). Le GET marche mieux mais peut échouer lorsque l'URL devient trop
longue : il ne faut pas dépasser 45 caractères pour la query string. Il existe cependant une
astuce pour dépasser cette limite : terminer l'URL par .pdf, ce qui trompe IE. Si vous utilisez
un formulaire, il suffit de rajouter un champ caché en dernière position :
<BR>
<BR>
<TABLE WIDTH="100%" BGCOLOR="#E0E0E0"><TR><TD>
<TT>
&lt;INPUT TYPE=&quot;HIDDEN&quot; NAME=&quot;ext&quot; VALUE=&quot;.pdf&quot;&gt;
</TT>
</TD></TR></TABLE><BR>
L'utilisation de session PHP cause également souvent des dysfonctionnements (il faut éviter
d'envoyer des en-têtes HTTP empêchant la mise en cache). Voir la question 5 pour un moyen
de résoudre le problème.
<BR>
<BR>
Pour éviter tous ces problèmes de manière fiable, il existe deux principales techniques :
<BR>
<BR>
- Désactiver le plug-in et utiliser Acrobat comme application externe. Pour cela, lancez
Acrobat ; dans le menu Fichier, Préférences, Générales, désactivez l'option "Intégrer au
navigateur Web" (pour Acrobat 5 : Edition, Préférences, Options, "Afficher dans le navigateur").
Puis, lorsque vous récupérez un PDF dans IE, ce dernier affiche la boîte "Ouvrir ce fichier" ou
"Enregistrer ce fichier". Décochez la case "Toujours demander avant d'ouvrir ce type de fichier"
et choisissez Ouvrir. Dorénavant les PDF s'ouvriront automatiquement dans une fenêtre Acrobat
indépendante.
<BR>
L'inconvénient de la méthode est qu'il faut toucher à la configuration du poste client, ce
qu'on peut faire en intranet mais pas pour Internet.
<BR>
<BR>
- Utiliser une technique de redirection. Le principe consiste à générer le PDF dans un fichier
temporaire sur le serveur et à rediriger le client dessus (en utilisant du JavaScript, pas
l'en-tête HTTP Location qui pose aussi des problèmes). Par exemple, à la fin du script, on
peut mettre :
<BR>
<BR>
<TABLE WIDTH="100%" BGCOLOR="#E0E0E0"><TR><TD>
<TT>
//D&eacute;termination d'un nom de fichier temporaire dans le r&eacute;pertoire courant<BR>
$file=basename(tempnam(getcwd(),'tmp'));<BR>
//Sauvegarde du PDF dans le fichier<BR>
$pdf-&gt;Output($file);<BR>
//Redirection JavaScript<BR>
echo &quot;&lt;HTML&gt;&lt;SCRIPT&gt;document.location='getpdf.php?f=$file';&lt;/SCRIPT&gt;&lt;/HTML&gt;&quot;;
</TT>
</TD></TR></TABLE><BR>
Puis ceci dans getpdf.php :
<BR>
<BR>
<TABLE WIDTH="100%" BGCOLOR="#E0E0E0"><TR><TD>
<TT>
&lt;?php<BR>
$f=$HTTP_GET_VARS['f'];<BR>
//Contr&ocirc;le du fichier (&agrave; ne pas oublier !)<BR>
if(substr($f,0,3)!='tmp' or strpos($f,'/') or strpos($f,'\\'))<BR>
&nbsp;&nbsp;&nbsp;&nbsp;die(&quot;Nom de fichier incorrect&quot;);<BR>
if(!file_exists($f))<BR>
&nbsp;&nbsp;&nbsp;&nbsp;die(&quot;Le fichier n'existe pas&quot;);<BR>
//Traitement de la requ&ecirc;te sp&eacute;ciale IE au cas o&ugrave;<BR>
if($HTTP_SERVER_VARS['HTTP_USER_AGENT']=='contype')<BR>
{<BR>
&nbsp;&nbsp;&nbsp;&nbsp;Header('Content-Type: application/pdf');<BR>
&nbsp;&nbsp;&nbsp;&nbsp;exit;<BR>
}<BR>
//Envoi du PDF<BR>
Header('Content-Type: application/pdf');<BR>
Header('Content-Length: '.filesize($f));<BR>
readfile($f);<BR>
//Suppression du fichier<BR>
unlink($f);<BR>
exit;<BR>
?&gt;
</TT>
</TD></TR></TABLE><BR>
Cette méthode fonctionne dans la plupart des cas, mais pose encore des problèmes avec IE6. La
méthode "ultime" consiste à rediriger directement sur le fichier temporaire. Ce dernier doit
donc avoir l'extension .pdf :
<BR>
<BR>
<TABLE WIDTH="100%" BGCOLOR="#E0E0E0"><TR><TD>
<TT>
//D&eacute;termination d'un nom de fichier temporaire dans le r&eacute;pertoire courant<BR>
$file=basename(tempnam(getcwd(),'tmp'));<BR>
rename($file,$file.'.pdf');<BR>
$file.='.pdf';<BR>
//Sauvegarde du PDF dans le fichier<BR>
$pdf-&gt;Output($file);<BR>
//Redirection JavaScript<BR>
echo &quot;&lt;HTML&gt;&lt;SCRIPT&gt;document.location='$file';&lt;/SCRIPT&gt;&lt;/HTML&gt;&quot;;
</TT>
</TD></TR></TABLE><BR>
Cette méthode transforme un PDF dynamique en PDF statique et évite ainsi tous les ennuis.
Par contre, il faut prévoir une procédure de nettoyage pour effacer les fichiers temporaires.
Par exemple :
<BR>
<BR>
<TABLE WIDTH="100%" BGCOLOR="#E0E0E0"><TR><TD>
<TT>
function CleanFiles($dir)<BR>
{<BR>
&nbsp;&nbsp;&nbsp;&nbsp;//Efface les fichiers temporaires<BR>
&nbsp;&nbsp;&nbsp;&nbsp;$t=time();<BR>
&nbsp;&nbsp;&nbsp;&nbsp;$h=opendir($dir);<BR>
&nbsp;&nbsp;&nbsp;&nbsp;while($file=readdir($h))<BR>
&nbsp;&nbsp;&nbsp;&nbsp;{<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(substr($file,0,3)=='tmp' and substr($file,-4)=='.pdf')<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$path=$dir.'/'.$file;<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if($t-filemtime($path)&gt;3600)<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@unlink($path);<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR>
&nbsp;&nbsp;&nbsp;&nbsp;}<BR>
&nbsp;&nbsp;&nbsp;&nbsp;closedir($h);<BR>
}
</TT>
</TD></TR></TABLE><BR>
Cette fonction efface tous les fichiers de la forme tmp*.pdf dans le répertoire spécifié qui
datent de plus d'une heure. Vous pouvez l'appeler où vous voulez, par exemple dans le script
qui génère le PDF.
<BR>
<BR>
Remarque : il est nécessaire d'ouvrir une nouvelle fenêtre pour le PDF, car on ne peut plus
revenir en arrière à cause de la redirection.</P>

<A NAME='18'></A><B>18.</B> <FONT CLASS='st'>Quelle est la taille limite des fichiers que je peux générer avec FPDF ?</FONT>
<P>Il n'y a pas de limite particulière. Il existe cependant certaines contraintes :
<BR>
<BR>
- La taille mémoire allouée par défaut aux scripts PHP est de 8 Mo. Pour de très gros
documents, en particulier avec des images, cette limite peut être atteinte (le fichier étant
construit en mémoire). Elle est paramétrée dans php.ini.
<BR>
<BR>
- Le temps d'exécution alloué par défaut est de 30 secondes. Cette limite peut bien entendu
être facilement dépassée. Elle est paramétrée dans php.ini et peut être éventuellement modifiée
à l'exécution par set_time_limit().
<BR>
<BR>
- Les navigateurs ont généralement un time-out de 5 minutes. Si vous envoyez le PDF directement
au navigateur et que vous dépassez cette limite, il sera perdu. Il est donc conseillé pour les
très gros documents de les générer dans un fichier, et d'envoyer des données de temps en temps
au navigateur (par exemple page 1, page 2... en utilisant flush() pour forcer l'envoi).
Lorsque le fichier est terminé, vous pouvez effectuer une redirection dessus avec JavaScript
ou bien créer un lien.
<BR>
Remarque : même lorsque le navigateur part en time-out, il est possible que le script continue
à s'exécuter sur le serveur.</P>

*Cette fonction retourne une liste alphabétique et un tableau html contenant les résultats
*d'une requête sql pour une lettre de l'alphabet donnée.
*Quand on clique sur une lettre de la liste alphabétique la page est rechargée et la
*fonction renvoie la liste et le tableau de résultat correspondant à la requête sql
*avec la lettre de l'alphabet sélectionnée.
* Elle nécéssite l'inclusion du fichier lib.form.php
*
*Le tableau associatif de formatage des lignes:
*-clé "Class_pair": contient le nom d'une classe css à utiliser pour le
* formatage des lignes de résultats paires.
*-clé "Class_impair": contient le nom d'une classe css à utiliser pour le
* formatage des lignes de résultats impaires.
*-clé "Style_pair": contient les syles à utiliser pour le
* formatage des lignes de résultats paires.
*-clé "Style_impair": contient les syles à utiliser pour le
* formatage des lignes de résultats impaires.
*-clé "Couleur_pair": la valeur héxadécimale de la couleur des lignes
* paires du tableau de résultats.
*-clé "Couleur_impair": la valeur héxadécimale de la couleur des lignes
* impaires du tableau de résultats.
* Il est conseillé d'utilser les styles ou les
* classes pour gérer la couleur.
*
*Le tableau associatif de formatage des résultats:
*Nous stockons des tableaux associatifs dans le tableau de formatage.
*Chaque ligne du tableau de formatage correspond à une colone, on doit
*les entrer dans l'orde d'affichage.
*-clé "Col_nom": chaine le nom du champ de la requête sql à afficher.
*-clé "Col_width": entier largeur de la colone
*-clé "Col_class": chaine nom de la classe css de la colone.
*-clé "Col_lien_href": chaine l'url de base pour créer un lien sur la colone.
*-clé "Col_lien_href_param": chaine nom du champ dans la requete SQL servant à compléter l'url.
*-clé "Col_lien_target": chaine la valeur de l'attribut 'target'du lien.
*-clé "Col_lien_class": chaine la valeur de l'attribut 'class'du lien.
*-clé "Col_lien_title": chaine la valeur de l'attribut 'title'du lien.

*
* @param string une chaine fournissant la base de l'url de la page où la fonction est utilisée.
* @param string la chaine correspondant aux paramètres à faire passer dans l'url.
* @param string la requete sql qui fournira le tableau pour une lettre donnée.
* @param string le code html d'ouverture du tableau entre la liste alphabétique et les lignes de résultat.
