- I have a couple of questions regarding the binary format of your run
- of the mill 16 color bitmap under Windows 3.1.
-
- In the Programmers Reference, the call to CreateBitmap takes as
- parameters the number of planes in the Bitmap and the number of Bits
- per Pixel. If you are specifying a 16 color bitmap, do you need to
- specify 4 bit planes, or 4 bits/pixel?
-
- Also, once a bitmap has been drawn into a MemDC, but before being
- BitBlt-ed to the screen, can I continue to manipulate the bmBits data
- from the BitMap structure?
-
- Any help greatly appreciated,
- Tom.
