Dear Duc,
If you read your own first mail with the code snippet you pasted:
virtual void operator () (osg::RenderInfo& renderInfo) const
{
#if !defined(OSG_GLES1_AVAILABLE) && !defined(OSG_GLES2_AVAILABLE)
glReadBuffer(_readBuffer);
#else
osg::notify(osg::NOTICE)<<"Error: GLES unable to do
glReadBuffer"<<std::endl;
#endif
I guess that's clear, right?
Cheers
Raymond

Hi,
it is hard to tell what is going wrong without further information.
For instance it is crucial to call the glReadPixel function in the
right moment. Could you provide some example that shows the problem?
Also: is the osgscreencapture or the osgviewers
screenshot-functionality working?
Cheers
Sebastian
