            Bug ID: 42727
           Summary: obsolete 128MB bitmap size limit
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
          Assignee: wine-bugs at winehq.org

source code to probe supported bitmap size

The current WINE bitmap implementation has a size limit of 128MiB dating back
to 2008 with a comment about Windows XP:
https://source.winehq.org/git/wine.git/blob/39935fe5ad889d537d828cc82771bdb969cdb2d4:/dlls/gdi32/bitmap.c#l197

    197     /* XP doesn't allow creating bitmaps larger than 128 MB */
    198     if (bm.bmHeight > 128 * 1024 * 1024 / bm.bmWidthBytes)
    199     {
    200         SetLastError( ERROR_NOT_ENOUGH_MEMORY );
    201         return 0;
    202     }

However, recent versions of Windows seem to have a higher limit, of 2GiB. 
Attached source code tries to create bitmaps with increasing sizes (each just
under 2^N bytes) and prints successes and eventual failure.

The bitmap test code seems to have a test for individual maximum dimension
(width), but not for maximum total bitmap size:
https://source.winehq.org/git/wine.git/blob/39935fe5ad889d537d828cc82771bdb969cdb2d4:/dlls/gdi32/tests/bitmap.c#l1487

Thanks for testing to users at

- I'll attach their results after submitting.
