My VideoPost plug-in needs to render sub pictures, that's why I call RenderDocument in the method execute and then copy the result picture in VPBUFFER_RGB. It works for a normal rendering.
The problem are coming as soon as the user wants to output the Alpha Channel or some Multipass.
VPBUFFER_RGB is a MultipassBitpmat so I tried to understand its contain. As I was expecting, the layer count is 1 during a normal rendering and more if the user wants multipass (count = multipass effect +1), alpha layer count is 1 if the user wants the alpha channel.
I thoughts that maybe if I create a MultipassBitmap with the same layers in it, renderdocument would maybe render thode data too in my sub pictures, but it doesn't work.
Well I need those data in my sub pictures. I need sometime to save them. How can I get them ?
