Setting the Color Depth for an Image
You can alter the color depth of an image.
Each pixel in a raster image stores color information. The amount of
information within each pixel is called depth and is measured in bits. Pixels
with more depth can store more information and therefore display more
colors. For instance, an 8-bit pixel can display one of 256 indexed colors (or,
in the case of grayscale images, shades of gray), while a 24-bit pixel can display
one of 16.7 million colors.
The following table shows the color depths supported by Raster Design and
the number of colors each depth can display.
