Win32s Device-Independent Bitmap Limit (115084)

SUMMARY

Under versions of Win32s prior to 1.25, a device-independent bitmap (DIB) is limited to a size of 2.3 MB. This size was chosen to accomodate a bitmap of 1024 by 768 pixels at 24 bits per pixel.

In Win32s 1.25a, this limit was increased to 1280 by 1024 pixels at 24 bits per pixel.

This limit can cause a variety of problems to occur, such as painting problems with SetDIBitstoDevice() if a larger bitmap is used.
