How to rotate monochrome images in GDI+
I am trying to rotate a monochrome Bitmap in GDI+ using RotateFlip method. When i try to rotate it by 90/270 I get a wrong image or the application crashes. But when I try to rotate it by 180 degrees it works fine. Hence I am now rotating all monochrome bitmaps twice through 180 and then rotating it again by the angle required.

Is this a known bug in GDI+? Any other good workarounds would be appreciated.
