[MonoTouch] CGImageSource from file

[Rolf Bjarne Kvinge]

Hi Jason,

You found a bug in MonoTouch (
https://bugzilla.xamarin.com/show_bug.cgi?id=3717).

You can quite easily work around it by passing a CGImageOptions:

CGImageSource.FromData (data, new CGImageSourceOptions ());

I hope this helps,
Rolf
