[osg-users] Copy a region of an image x,y,w,h / s,t,r

[Julien Valentin]

Hi Steal,
http://forum.openscenegraph.org/viewtopic.php?t=7810&highlight=GLU
All image manipulation methods are GLU based, which require a proper GL context to be created and made current.
Perhaps popping a dummy osgViewer before calling these methods should do the trick...
Cheers
