I was asking about "painting with transparency" because that is what you do in Canvas. There, you are always working with the image on a page -- like the Document mode in PL32. In Canvas, you click once on an image to select it so that you can do stuff like moving it around on the page, applying Curves, duplicating the image to make a mask, cropping the image, etc. -- kind of global stuff. You double click it to put it into "edit" mode so you can use your paint tools, brushes, erasers, etc. on the image. If you Alt/Option-double click on the image, you can paint or erase with transparency. Unlike PL32, Canvas does not create a separate layer for every image action. Their notion of what a layer is, is quite different from that of PL32.
As I understand it, in PL32 when you go menu bar | layer | layer properties and check "Use transparency", it creates a mask layer. This is in keeping with PL32's technology, where everything is a layer. gYou can't "paint" with transparency -- only erase to transparency, but since you can apply any brush shape or parameter to the eraser (as Canvas can do too), the result is exactly the same.
Am I getting it right?
