Bug ID: 55398
           Summary: GDI+ does not support EXIF orientation information
           Product: Wine
           Version: 8.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdiplus
          Assignee: [e-mail]
          Reporter: [e-mail]
                CC: [e-mail]
      Distribution: ---

GDI+ does not support parsing EXIF orientation from JPEG images.

This seemingly leads to some apps being unable to displaying images in the
correct orientation, making the image look rotated.

What application(s)? Can you provide a reproducible example?

Affected Applications:

- (Suspected) KakaoTalk image preview ignores EXIF orientation. Thumbnails are
not affected, presumably because the image is pre-processed by the server with
the rotation applied.

The support for EXIF in gdiplus is provided by EmfPlusCompressedImage Object:
https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-emfplus/9c0...

And these objects are used by EmfPlusBitmap:
https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-emfplus/112...

It seems that EXIF support was implemented only for PNG:

Please use winetricks to install native gdiplus.

Is this issue is resolved with native gdiplus?

Actually no, which led me to believe that the actual missing facility lies in
one of the backend components (e.g., windowscodecs, which seems to emit a lot
of "unsupported" messages in channel wincodecs).  Maybe I could borrow
windowscodecs.dll from Windows too and test with it; not sure how well it will
work out though.  Thanks for reminding me of using winetricks for
feature-parity testing though.

It's still true that GDI+ does not support EXIF, directly or indirectly, so
I'll leave this issue open.  I'll submit another ticket once I identify the
missing API/codec/format, but this will take a while.

*once I identify the missing API/codec/format which is completely unrelated to
GDI+, which would be out-of-scope for this bug ticket.

Neither WIC/windowscodecs nor GDI+ currently support metadata from JPEG files. 
While I have begun working on the WIC portion, it is rather more complex than
the other formats I have worked on, and will take a little while.  I believe
the GDI+ portion is best left until the WIC portion is in decent shape.
