Thanks for the fast response. Actually I was trying to get the
composited "output" and manipulate that before rendering to the
screen ( to give openGl 'effects' to the whole composited 'output'
since it may be available as openGL context.)
Can you tell me how we can access the composite output and can
manipulate that before it is rendered to the screen/ pBuffer or
back to main memory .
Use the Render in Image patch if you want to do that inside the
composition itself, or render the composition to a pBuffer using a
QCRenderer if you are writing a custom application and write your own
GL code.
I got a sample code coming that shows how to do the 2nd case.
