Notes 
•
You can create layer masks based on 
transparency for pixel-based layers only. 
Other layers must first be converted to 
default layers.
•
Earlier versions of Corel Painter used 
layer visibility masks. If you have a file 
with a modified visibility mask that was 
created with an earlier version of Corel 
Painter, use this procedure to load the 
visibility mask to a layer mask.
To copy a channel to a layer mask:
1 Align the layer with the portion of 
the channel you want. 
2 Select the layer on the Layers 
palette.
3 Click the Create Layer Mask 
button.
A blank layer mask is created.
4 On the Channels palette, select the 
channel you want to copy.
5 Click the palette menu arrow, and

box, choose the layer mask from 
the Destination pop-up menu. 
Corel Painter copies to the layer 
mask the portion of the channel 
that coincides with the layer 
content.
Selecting and Viewing Layer 
Masks
Before you work with a layer mask, 
you must select it. You can also view a 
layer mask as a grayscale image.

are distinct operations—you can select 
a layer mask without viewing it.

layer that has a layer mask.
The layer mask is displayed on the 
Channels palette.

• On the Channels palette, click 
the layer mask.
• On the Layers palette, click the 
layer mask icon   next to the 
layer name.
To view a layer mask:
1 Select a layer with a layer mask.
2 On the Channels palette, click the 
layer mask. 
In this mode, the RGB image is 
hidden.

mask item to close the eye.
