Saving masks and alpha channels

Since only one mask can be active in an image, each new mask you create replaces the current mask. However, before you create a mask, you can save the current mask to an alpha channel in the image so that it can be reused. When you save an image to a file format that supports mask information, such as Corel PHOTO-PAINT (CPT) or TIFF, the current mask and all alpha channels are saved with the image.

You can also save the current mask or an alpha channel to disk as a separate file. Saving a mask or an alpha channel lets you use masks in other images. This is especially useful if you want to save an image to a file format that doesn’t support mask information but you want to keep copies of the masks used to edit that image. A color mask can also be saved to disk as a separate file. For more information about color masks, see Defining editable areas by using color information.
