[vtk-developers] Bug in offscreen rendering

[Daniel Aguilera]

Hi all,

In the class vtkXOpenGlRenderWindow the method SetSize (int x,int y) begins
with

   if ((this->Size[0] != x)|| (this->Size[1] != y))
      {
      this->Modified();
      this->Size[0] = x;
      this->Size[1] = y;
      }

And then
   if(this->OffScreenRendering)
      {
      this->ResizeOffscreenWindow(x,y)
      }

But the method ResizeOffscreenWindow(x,y) begins with a test always true:
   ...
   if ((this->Size[0] != x)|| (this->Size[1] != y))
      {
      return;
      }

So I suggest to suppress this test : this works very well for my
application.

Best regards,
Daniel Aguilera
