[Paraview] Re:Still Problem with Offscreen

[Young Fan]

The compile problem has been solved ,thanks.
  But now I met another problem still about offscreen.
  The offscreen function act up well in C/S mode, but failed with pvbatch.
  The Rendering Image still was sent to a RenderWindow, the saved into a Image file.
  I analyzed the sourcecode about method "setoffscreenrendering" in class "vtkXOpenGLRenderwindow". 
  In my opinion, it is caused by a evaluation failure of two variables :"PixmapContextId" and "PbufferContextId" when running pvbatch.
  There is the sourcecode involved:  
  _________________________
  this->vtkRenderWindow::SetOffScreenRendering(i);
      if(i)
        {
        this->Internal->ScreenDoubleBuffer = this->DoubleBuffer;    
        this->DoubleBuffer = 0;
        this->Internal->ScreenMapped = this->Mapped;
        this->Mapped = 0;
        if(!this->Internal->PixmapContextId || !this->Internal->PbufferContextId)
          {
          this->WindowInitialize();
          }
        }

  I wonder if it is a bug, or just a function that havent been done because of no use and ? How to get rid of the pop-up rendering window when running paraview in pvbatch???
   
  Thanks!

  If you are compiling ParaView 2.4 yourself, then 
just check out the ParaView-2-4 branch from 
CVS.  The change in vtkXOpenGLRenderWindow.cxx 
for mangled mesa has been added to that branch.
