Generating channels automatically
Corel Painter can automatically generate a channel based on the light and dark areas of a number of
sources, including paper, pattern, and clone source. For example, you can create a channel based on the
luminance values of a clone. You can also create a channel based on a range of colors. These methods are
similar to automatically generating pixel-based selections. For more information, see “Creating pixel-based
selections” on page 583.
