no - as i described, it must be possible to 
create an offscreen GLContext.

then you can resize it and render into it

the code can be seen at "gl4java.swing.GLJPanel::paintComponent"

well, you do not need to show it like the swing implementation
within an BufferedImage,
in you case, you just should do your opengl rendering and then use the
"gl4java.util.textures.TGATextureGrabber" as shown in "morph3d" !

cheers, sven
