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.

Like a grayscale image, a channel can have 256 values in it. Inverting a channel is equivalent to creating the negative of a grayscale image. For example, a pixel with 80% luminance will have 20% luminance when inverted. A pixel with 30% luminance will have 70% luminance when inverted.

The channel displays as a red overlay on the image in the Preview window of the New Channel from Color Range dialog box. You can drag in the Preview window to display other parts of the image.
