            Bug ID: 50636
           Summary: Reading indexed bitmap wrongly returns 32bit instead
                    of 8bit
           Product: Wine
           Version: 6.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: eri0onpm(a)gmail.com
      Distribution: ---

When using C# and .NET 4.5, the Image.GetPixelFormatSize method returns 32 for
an indexed bitmap that should return 8

https://docs.microsoft.com/en-us/dotnet/api/system.drawing.image.getpixelfor...

I think this should have been fixed by commit
ee6dd81e922145ca7b70cb1de01a8795119b824b from Dmitry Timoshkov but I am unsure
if this commit is on Wine 6.

And a lot of the handling of the Bitmap class of dot net seems to go to
wine/dlls/gdiplus/image.c , are there known issues there with indexed bitmaps?

Using Wine built from the current source, I can't reproduce the error anymore,
so my guess is this got fixed somewhere between Wine 6.0 and now.
