This format is used for storing bitmap images. It supports many different file types and compression algorithms. One Palm bitmap file can contain multiple versions of the same images with different colors. These files are used on PALM devices.
This is a color model display format that uses the three primary colors (blue, red and green) to create an image. Each color can have up to 255 gradations, allowing for color depths of up to 48 bits. RGB supports the display of 16,777,216 colors.
