The command merges the
layer mask with the current layer. The transparency information in the
layer mask is transferred to the alpha channel and the layer mask is
removed. If the active layer does not have a layer mask, the menu entry
is insensitive and grayed out. See the
section for more information.
Activating the Command
You can access this command from the image menubar through
→ → ,
or from the pop-up menu you get by right-clicking on the active
layer in the Layers Dialog.
