Selecting a color depth
Color depth refers to the number of colors that an image contains. FotoCanvas
Lite displays images using many different color depths. You can convert an image
to any of the following color depths:
•
Black and White: This type of color depth uses a two color, black and
white palette.
• 16 Grays: This type of color depth uses a 16 color grayscale palette.
• 256 Grays: This type of color depth uses a 256 color grayscale palette.
• 16 Colors: This type of color depth uses a 16 color palette.
• 256 Colors: This type of color depth uses a 256 color palette. Images
saved using the GIF format use 256 colors by default.
• Highcolor: This type of color depth uses a 32,768 color palette.
•
Truecolor: This type of color depth uses a 16,777,216 color palette that is
composed of all colors visible to the human eye.
You cannot use certain image enhancement tools, filters, blends, and adjustment
options unless you have a Hicolor or Truecolor image. If you want to edit an image
that is not Hicolor or Truecolor, you can convert it, edit the image, and then convert
if back to its original color depth.
