Serbian abstract

Da bi se slika predstavila na računaru, mora se digitalizovati - predstaviti u obliku matrice piksela. Pri tome se, u skladu sa sadržajem i namenom slike, odlučujemo koliko informacija slika treba da sadrži. Odluku o grafičkom formatu slike donosimo vodeći računa o tehnikama kompresije koje grafički format podržava. Za editovanje slika bolji su formati koji podatke ne komprimuju uopšte ili ih komprimuju bez gubitaka (PCX, TIFF, BMP, PNG-24); za prikaz slika na Webu, koriste se formati koji koriste algoritme sa visokim stepenom kompresije (GIF, JPEG, PNG). Važne osobine formata slika na Webu su i progresivni prikaz i transparentnost.
