Text and Rasterization
Because all text layers are contained in groups, rasterization affects how text interacts
with other objects within your project.
Note: Text can be rasterized independently of the group in which it lives. Doing this
affects how the text interacts with objects within 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 on the left shows the nonrasterized 2D group (“titles”) containing
text. In the illustration on the right, the text interacts with the image beneath it in the
layer stack because the text is set to the Add blend mode (notice the texture in the word
“leopard” created by the image beneath it).
In the next example, the group that contains the text and upper leopard image is
rasterized—triggered in this case by selecting the Crop checkbox in the Properties tab
of the group. The text’s Add blend mode and the leopard image’s Multiply blend mode
no longer interact with the object beneath them (the lower leopard image) in the layer
stack. Notice that the group icon for the rasterized group now appears with a frame
around the icon (the icon immediately to the left of the “Group - titles” group).
