Oben links: Beim Vergrößern von Rasterbildern gehen Details verloren. Unten links: Beim Vergrößern von Vektorbildern bleiben Details erhalten. Rechts: Das Bild enthält Raster- (rote Beete, Holz) und Vektorgrafiken (Logo). Wird es als Rasterbild gespeichert, sieht es beim Vergrößern verpixelt aus.
Rastergrafiken.
Bitmap- oder Rasterbilder (BMP, JPEG, PICT, PNG, PSD oder TIFF) bestehen wie digitale Fotos aus einem Pixel-Raster. Wenn sie vergrößert werden, gehen Details verloren.
Vektorgrafiken.
Vektorbilder bestehen aus Linien, Formen und anderen Grafikkomponenten, die in einem auf geometrischen Formeln basierenden Format gespeichert werden. Beim Vergrößern bleiben die Kanten sauber und scharf.
