Related to this, I would love to have a function that would enable me to create a layer mask from alpha channel or apply it to the existing mask. That way it would be possible to increase opacity with a layer mask by first applying the alpha channel to the mask and then 'darkening' the layer mask. To me this is a missing link between alpha channel and mask. We already have similar function when working with selections/channels. cheers -- Jakub Steiner <[EMAIL PROTECTED]> Ximian, Inc.
