Re: Problem with shadow render opengl

[Daniele C. <dca...@in...>]

Start with a drawcontext create from window and all is ok
I want create a bitmap of view  so I create  pixmap drawcontext (I can 
create a image with large dimension).
My masterDrawContext  is the drawcontext obtain with 
Q3View_GetDrawContext from window view.
I make the render into pixmap drawcontext
I create a windows bitmap, for this I get drawcontext  with 
Q3View_GetDrawContext obtain from  pixmap drawcontext and get pixmap.
When I have my  windows bitmap I return to drawcontext create from window
