Chapter 25 About rasterization 1048
Note: Text can be rasterized independently of the group in which it resides, and that
rasterization affects how the text interacts with objects in its own group. For example, applying
a Circle Blur filter to text that exists in 3D space (such as text on a path) causes the text to no
longer intersect with other objects in the same group. The same operations that cause a 3D
group to rasterize cause 3D text to rasterize. In some situations, selecting the Flatten checkbox in
the Layout pane of the Text Inspector can minimize this effect.
The following example shows the nonrasterized 2D group (Group 1) containing text. The text
interacts with the image beneath it in the layer stack because the text is set to the Soft Light
blend mode. (Notice the texture in the words “big cats” created by the image beneath it.)
In the next example, the 2D group that contains the text is rasterized—triggered in this case by
selecting the Crop checkbox in the group’s Properties Inspector. The text’s Soft Light blend mode
no longer interacts with the object beneath it (the tiger image) in the layer stack. In the Layers
list, a rasterization frame now appears around the Group 1 icon.
For more information on rasterization with 2D and 3D groups, see Groups and rasterization on
page 1045.
Shapes and rasterization
When a group becomes rasterized, all masks, shapes, and paint strokes in that group are affected
and may no longer interact with other layers and groups as expected. Because paint strokes are
rendered in a plane, they are always rasterized (independent of other objects in the same group).
This affects how the dabs that comprise a paint stroke interact with objects in the same group.
Note: Because a paint stroke is always rasterized, no rasterization indicator appears around the
paint stroke icon.
