Corel Painter 257
If you’ve finished working with a layer
mask, you can delete it. You can also
clear a layer mask without deleting it,
leaving you with a blank mask.
The layer mask is a grayscale image.
By inverting it, you can make dark
pixels light, and light pixels dark.
You can disable a layer mask, which
lets you view the entire layer. The
layer mask can be re-enabled at any
time.
If you like the result of a layer mask,
you can apply it. This permanently
removes the hidden parts of the layer
and deletes the layer mask.
Although a layer mask does not
protect areas of a layer from being
edited, you can load a layer mask to a
selection. The selection provides
protection to the hidden parts of the
layer. For more information about
selections, refer to “Working with
Selections” on page203.
The name of a layer mask on the
Channels palette reflects the name of
the layer (Layer Name Layer Mask).
Although you cannot change the
name of a layer mask, it automatically
updates if you change the layer name.
When you move a layer, Corel Painter
also moves the layer mask to maintain
the pixel correspondence.
