Bitmap Graphics

Definitions

Bitmap image- Bitmap images are stored as a series of pixels. Pixel- A pixel is actually a very small square that is assigned a color, and then arranged in a pattern to form a bitmap image.

Color Depth

Color depth is either the number of bits used to indicate the color of a single pixel, in a bitmap image, or the number of bits used for each color component of a single pixel. This means the number of bits needed to code an image. For example an image will only need 2 bit color depth for black and white, such as the following image...

although if an image has 24 bit color depth, it can code up to 16777216 colors!
