Irrlicht Engine

I'm trying to capture the screen with createScreenShot ,
On the simulator I get incorrect color of the texture and in the device I don't get anything.
please help,
any idea how to patch it ?
thanks

I Found a solution, in displayInitialize of CIrrDeviceiOS I added

color.getBlue() * inv, color ...

Thanks, I'll try to crop and scale the texture.
Maybe I can change irrlicht code not to clear the background image of the view.

I tried this code on the Hello world sample but still I don't see the texture.

Thanks
