When a group object is selected, changing the opacity applies to the
group as a whole. Objects that were opaque do not become transpar-
ent to other objects in the group if you reduce the opacity of the group
object.
If you ungroup an object, the group opacity setting is removed and
the opacity of each separate object is restored.
Consider a group of three objects whose opacities are 30%, 60%, and
100%. If you set the opacity of the group object to 50%, the opacities
of the individual objects will appear to be 15%, 30%, and 50% rela-
tive to the background. If you ungroup the objects, their opacities will
be restored to 30%, 60%, and 100%.
Controlling the scope of transparency effects
All vector objects have scope settings that control what parts of the
objects are affected by transparency.
The scope setting can limit transparency to an objects fill ink only.
Or, it can apply transparency to the fill ink and the pen ink on the
objects stroke.
The scope setting controls all transparency effects applied to vector
objects, including opacity, channel masks, vector masks, and transfer
modes.
Each vector object has a scope setting. Scope settings do not affect
text objects, paint objects, or group objects.
You can change the scope setting of a selected vector object using the
Transparency palette. An objects scope setting remains the same
unless you use the Transparency palette to change it. See Using the
Transparency palette on page 20.355.
The scope setting can affect the time needed to print an object. When
an object has a reduced opacity setting (but no other transparency
effects) and the scope is Fill, Canvas can print the object on Post-
Script printers without rendering. If the scope is Fill & Stroke, Can-
vas renders the object and prints it as an image. An image usually
contains more data than a vector object, so this can increase the time
required to print an object.
