I looking for the right command in c# to do this:
previewImg.Bitmap.ConvertTo(corel.cdrImageType.cdrGrayscaleImage);
Remo,
I do not think Bitmap Mask is currently support via VBA or C#.

Looking at the example image above I thought that a transparency mask may also be a nice solution (just clone the image and adjust so the brightness becomes a mask), but turns out that is also not available via macros. Strange how these things are with CorelDRAW.
