Image handling, Page layout


This function must be called to prepare the image before it is used as a mask for another image. The mask image must be a grayscale image, and be either 1-bit or 8-bit. Depending on your needs you may want to call ReverseImage which will reverse the effects of the mask. A soft-mask is just a normal image, so if you have an image setup as a stencil mask and no longer want it to be a mask just change it to a soft mask image (MaskType = 2).
