background color. You can change the foreground color and turn the
transparency of the background color on and off.
Bitonal raster images are images consisting only of a foreground color and a
background color. When you attach a bitonal image, the foreground pixels
in the image inherit the current settings for color. In addition to the
modifications you make to any attached image, you can modify bitonal images
by changing the foreground color and by turning on and off the transparency
of the background.
NOTE Bitonal images and their boundaries are always the same color.
