Here you see the outline of a letter, the cap H, which is the thin black line, the contour, which is how it is stored in memory, superimposed on the bitmap, which is the grey area, which is how it's displayed on the screen.
Ovdje vidite obris slova, velikog H, tanku crnu liniju, konturu, ono što se pohranjuje u memoriji, stavljenu preko bitmape, to je ovo sivo područje, što pak predstavlja ono što se prikazuje na zaslonu.
