[Haskell-cafe] rotate image

Hello, I already studied the references of gtk2hs for hours, as well as searched in the web, but didn't found any working solution. The problem is to load an image, a png with alpha channel, rotate it e.g. 10 degree, and show it on the screen, basically as when it would be shown with imageNewFromFile with transparency. Thanks in advance for your help. -- Best regards H.
