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 object’s fill ink only. Or, it can apply transparency to the fill ink and the pen ink on the object’s 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 object’s 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.
