[vtkusers] How to set the resolution when I save vtkRenderWindow to jpeg?

[Helend]

Thank you very much!

but your method can not set the size of vtkRenderWindow was bigger than the
screen size.

I use the class vtkRenderLargeImage can solve my problem.

This is the sample Tcl link and codes:

vtkRenderLargeImage renderLarge
renderLarge SetInput ren
renderLarge SetMagnification 4

vtkTIFFWriter writer
writer SetInputConnection [renderLarge GetOutputPort]
writer SetFileName largeImage.tif
writer Write
