Bitmap

Bitmap Image

Most images you see on your computer are composed of bitmaps. A bitmap is a map of dots, or bits (hence the name), that looks like a picture as long you are sitting a reasonable distance away from the screen.

Common bitmap filetypes include BMP (the raw bitmap format), as well as JPEG, GIF, PICT, PCX, and TIFF. Because bitmap images are made up of a bunch of dots, if you zoom in on a bitmap, it appears to be very blocky. Vector graphics (created in programs such as Freehand, Illustrator, or CorelDraw) can scale larger without getting blocky.

File extension: .BMP
