[osg-users] How to convert osg::Texture to osg::Image?

[michael kapelko]

Hi.
I have osg::Texture that is attached to camera, it contains a rendered
scene (deferred rendering). I want to save it to a PNG file.
I tried to use osg::Texture::getImage(), but the resulting osg::Image seems
to be invalid, because osgDB::writeImageFile() crashes with it.
What's the correct way to convert Texture to Image?
Thanks.
