To turn off the transparency preview: Press the Asterisk (*)
key, or choose Hide Transparency Preview in the context menu.
To restore the transparency preview: Choose Show Transpar-
ency Preview in the context menu. If you dont choose the command,
Canvas restores the preview setting each time you leave edit mode.
To set the Transparency preview: Choose Canvas > Prefer-
ences (Mac) or File > Preferences (Windows). Click the Display tab
in the Preferences dialog box and select an option in the Transpar-
ency area. Click Background Preview to preview background objects
only. Click Total Preview to preview background and foreground
objects. Click No Preview to display transparent objects against a
checkerboard pattern for editing.
Note: If you select the No Preview preference, you cant use the con-
text menu to change the preview while you edit an object.
The preview preference affects what you see when you paint in a
transparent paint object or edit any paint object. If objects are in front
of the paint object, you can see the objects while editing if you select
Total Preview. If you select Background Preview or No Preview,
foreground objects are not displayed when you edit a paint object or a
channel mask.
Channel masks
A channel mask is a special channel that defines transparency in an
object. While channels are typically associated with paint objects,
you can apply a channel mask to any type of object.
