En haut à gauche : les images pixellisées perdent en détail lorsqu’elles sont agrandies. En bas à gauche : les images vectorielles restent nettes une fois agrandies. À droite : cette image se compose d’éléments pixellisés (radis, bois) et vectoriels (logo de la ferme). Si elle est enregistrée dans un format d’image pixellisé, les pixels apparaîtront lorsqu’elle sera agrandie.
Images pixellisées
Les images pixellisées (BMP, JPEG, PICT, PNG, PSD ou TIFF) se composent d’une grille de pixels, comme dans une photographie numérique, et perdent en détail lorsqu’elles sont agrandies.
Images vectorielles
Les images vectorielles se composent de lignes, de formes et d’autres éléments graphiques stockés dans un format qui utilise des formules géométriques. Lorsqu’elles sont agrandies, les contours restent parfaitement nets.
