Code Issues Projects Releases Packages Wiki Activity

- Moved SelectBitmap/Font to their proper places.

Browse source 
- Correct CreateCompatibleBitmap issues, finding more bugs and noted them.
- DibObj.c is a work in progress, needing more love. Managing SEH in a proper manner, fixing the SEH abuse.
- Wine gdi bitmap cross tests looking better, 16 bpp down to 50 faults.
- Need full spectrum testing, I exhausted my test suite so anything will do.

MSDN Note: When a memory device context is created, it initially

device context is used in CreateCompatibleBitmap, the bitmap that
is created is a monochrome bitmap. To create a color bitmap, use
the hDC that was used to create the memory device context, as
