			Un composant est un objet qui peut être ajouté à une <a href="Image.html">Image</a>. Les composants sont indépendants les uns des autres. La classe <a href="Component.html">Component</a> est une classe abstraite, dont doivent dériver tous les objets qui vont pouvoir être ajoutés sur une image.

			Sur un composant, l'axe des abscisses rejoint l'axe des ordonnées sur le coin haut-gauche. Le coin haut-gauche du composant a donc pour coordonnées (0, 0) et le coin bas-droite (largeur, hauteur). Par exemple, sur une image de largeur 100 et de hauteur 50, un point à 50 sur l'axe des abscisses et 25 sur l'axe des ordonnées sera au centre de l'image.
