There's a lot going on in this patch and the vague commit message doesn't help. I'd suggest a patch that fixes CreateIconIndirect() first and a second patch to fix CreateIcon(), then write more description commit messages.

Did you really try this on a 1 bpp display?
Huw.
Thanks for reviewing.

There's a lot going on in this patch and the vague commit message doesn't help. I'd suggest a patch that fixes CreateIconIndirect() first and a second patch to fix CreateIcon(), then write more description commit messages.
Some of the logic in CreateIconIndirect() should be in CreateIcon(), so there is no easy way of fixing CreateIconIndirect() alone without breaking CreateIcon() and the tests.
More description is a good idea.

No, because they get initialized later in CreateIconIndirect(), so I think there is no need to initialize them here.

No, I don't have a 1 bpp display to test it visually. However, I covered 1 bpp bitmap in conformance tests, tested the result image width, height, bpp.
I also tested the patch against a sample application downloaded online which creates icon with masks with CreateIconIndirect(). And after this patch, the application is visually fine.
I could add some visual tests in conformance test if necessary.
Huw.
Thanks, Zhiyi

I haven't looked hard enough, but would it be possible to do it the other way around: add the logic to CreateIcon() first and then remove the stuff in CreateIconIndirect() in a 2nd patch?
More description is a good idea.
Looking forward to it ;-)

Another thing, if you moved CreateIcon() to below stretch_blt_icon() (in fact below CreateIconIndirect() would make most sense), then you don't need this. I'd suggest making the moving patch a NOP, that doesn't do anything else.

No, because they get initialized later in CreateIconIndirect(), so I think there is no need to initialize them here.
Well CreateIconIndirect() ignores these params, but we should still probably initialize them, so set them to zero. That can be a separate patch.

My point was that 1 bpp displays don't exist. So you can replace this variable with TRUE throughout (and then simplify any relevant code).
