           Summary: Scaled-down bitmaps are always of poor quality
           Product: Mono: Class Libraries
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: libgdiplus

Created an attachment (id=234506)
 --> (https://bugzilla.novell.com/attachment.cgi?id=234506)
zip containing test case

Recipe:
=======
- unzip scaledown.zip
- gmcs scaledown.cs -r:System.Drawing
- mono scaledown.exe time.jpg time_mono.png

The attached zip already contains the resulting pngs from running the above on
mono, on ms.net and from running ImageMagicks "convert -resize 25% time.jpg
time_imagemagick.png".

The quality on Mono is far below that on .NET and when using ImageMagick.
