            Bug ID: 51834
           Summary: EMF DC emits invalid EMF when calling StretchDiBits
                    with info->bmiHeader.biSizeImage = 0
           Product: Wine
           Version: 6.18
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
          Assignee: wine-bugs(a)winehq.org
          Reporter: jinoh.kang.kr(a)gmail.com
                CC: jacek(a)codeweavers.com, zzhang(a)codeweavers.com
      Distribution: ---

BITMAPINFOHEADER allows setting biSizeImage to zero when biCompression is
BI_RGB.

However, the Wine EMF DC does not handle this case and takes the biSizeImage
value as-is.

This results in an invalid Enhanced Metafile output.
