Creating masks

You can create a mask from an image by loading the image file from disk. When you use an image as a mask for another image, Corel PaintShop Pro applies the mask as a grayscale image. The source image is not altered. You can also create a mask by customizing one of the sample masks included with Corel PaintShop Pro.

An example of an image used as a mask

You can use a selection to create a mask that shows or hides the selection. You can use this mask as a starting point for creating artistic effects.

You can also create a mask from a channel by first splitting an image into its RGB, HSL, or CMYK channels. Corel PaintShop Pro creates a grayscale image for each channel. You can use one of these channel images to create a mask for the original image or for another image.
