CreateCompatibleBitmap and memory

[CodeBrain]

I am trying to create a bitmap for a DC using CreateCompatibleBitmap. But I have the problem that my bitmap can be very large. Say 6000x4000 pixel with (32bit). If I try to create such a large bitmap CreateCompatibleBitmap always fails and GetLastError returns ERROR_NOT_ENOUGH_MEMORY. OK, I have a large bitmap but I should have enough memory on my PC for such a large bitmap... So why has CreateCompatibleBitmap such problems to find enough memory? Can I split the bitmap in more junks automatically e.g. using a DIB instead of the DDB? Any response welcome. Thanks in advance

You should be able to create bitmaps of the size mentioned, even though it does require 96000000 bytes of memory (image bits only).

I recommend going to the bitmap section and see if any of those programs has the same problem. Good luck! INTP

I made some additional tests. I have found out that 6000x4000 works, but 6000x4100 does not work. :confused: I will take a look on the bitmap section, maybe I'll find something.
