Description bugzilla.xamarin.com 2013-08-15 09:17:30 UTC
The function FromFile in System.Drawing.Image accepts a filename, uses File.Exists to check it exists then calls GDIPlus.GdipLoadImageFromFile

File.Exists operates within Mono.IO portability framework but GDIPlus.GdipLoadImageFromFile doesn't.

This means that a file that was checked with File.Exists can fail to load when passed to GDIPlus.

I think either GDIPlus needs to interpret filenames via the mono portability framework, or System.Drawing.Image needs to convert the filename if necessary before passing it on to GDIPlus.
