Alfa channels in pictures
Support of transparency in pictures that have alpha channels.
I guess by "alpha channel" you really mean "alpha compositing".
An Alpha Channel sets the degree of transparency of each pixel of an image by a value between 0 and 1, and that is what HighDesign does.
If you want to exclude certain colors, like white, then you would have to create a mask, either by color or by shape, which can be used for compositing. Masked images can then be composed in different ways, like Over, In, Out, XOR, etc. In this case, you are right, image masks aren't available.
