ABSTRACT
You might be wondering why the Grow Bounds effect is useful, especially when compared with the Collapse Transformations switch which appears to do the same thing. For starters, Collapse Transformations doesn’t help in situations like those seen in Fig. 21.4 , where the effect causes the pixels on a layer to go beyond the layer’s boundaries. The Grow Bounds effect is useful for working with individual layers not just compositions. The Pixels parameter allows you precise control over how much the layer extends beyond its boundaries. And also, Collapse Transformations also changes blend modes and other properties, which you might not want changed.
