Pictures in HighDesign can be set to any alpha value: Select the image and choose Edit > Properties > Image or open the contextual menu and choose Edit Properties.

If you were referring to imported images, then I believe PNG and Tiff alpha channels are supported too.

Hey M-Rick,

Are you using that to dress you r images the way people sometimes do in Photoshop?

Just curious. If so I wouldn't mind seeing the results.

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.
