I need some direction from someone more familiar with the particulars of using BitBlt.
In my current project there are 3 forms: srcForm dstForm maskForm of which scrForm and dstForm are 32-bit depth and the maskForm is 1-bit depth. The maskForm contains black pixels in a non-rectangular shape.
I want to copy pixels from the scrForm onto the dstForm using the maskForm for inclusion. The srcForm is smaller in extent than the dstForm. The maskForm is the same size as the dstForm. I've tried a number of things, and frankly went into this believing it would be very simple, but ended up implementing pixel copies. There must be a smarter way.
