To apply transparency effects to the entire object, select Fill
& Stroke.
To apply transparency effects to the objects fill ink only,
select Fill.
Transparency masks
Transparency masks let you create complex transparency effects.
You can use transparency masks with vector, paint, text, and group
objects.
Channel masks and vector masks are the two types of transparency
masks available. You can apply either mask type to vector, text,
paint, and group objects. An object can have only one mask, but it
can have a mask along with other effects such as opacity and transfer
mode.
A channel mask creates transparency based on a grayscale image. A
channel mask is part of an object, the same way an image channel is
part of a paint object. You can use painting tools and image-editing
techniques in a channel mask. For example, you can make a vignette
by painting an oval in a channel mask.
A vector mask creates transparency based on a vector gradient or the
colors of a vector object. Vector masks can produce gradual transpar-
ency changes the same way that gradient inks produce gradual color
changes. You can drag a tool to create radial, linear, elliptical, and
rectangular vector masks, or you can use an object as a vector mask.
The following sections describe methods for using channel masks
and vector masks.
Changing the transparency preview
When you edit paint objects or channel masks, Canvas previews
transparency effects according to a preference setting. You can tem-
porarily change the preview when you are in channel mask edit
mode.
When you edit a channel mask with no preview, a checkerboard pat-
tern lets you focus on the transparent object. The checkerboard hides
objects behind the transparent object, while showing the transparent
areas in the object you are editing.
Note: In Total Preview mode, Canvas shows objects that are in front
and in back of a paint object or channel mask you are editing.
