Image Compression (GIF/TIFF/PCX)
The picture resolution. This is defined by the number of pixels in the x-and y-directions.
The number of colors per pixel. If N bits are used for the bit color then the total number of displayable colors will be 2 N . For example an 8-bit color field defines 256 colors, a 24-bit color field gives 224 or 16.7M colors. Many new computer systems allow for 32-bit color which gives over 4 billion colors.
Palette size. Some systems reduce the number of bits used to display a color by reducing the number of displayable colors for a given palette size.
