[osg-users] Image capture in memory

[Trajce Nikolov NICK]

Hi Catalin,

I don't have build env at the moment but looking into the code, can you try
this:

osgposter.cpp, Ln: 377
just add:
viewer_camera->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);

this shouldn't open any window
