[vtkusers] Writing Postscript files from VTK

[Goodwin Lawlor]

Hi Carl,

If you dont have any luck with gl2ps I have a work around for writing PS
vector files from VTK under windows.

1. Use vtkCGMWriter to write a scene to file. This class is included in
vtk4.n but it is not built... so you have to add it yourself to the cmake
files and re-compile. Under windows and the borland compiler there were a
couple of small bugs. Email me if  they cause you any problems.

2. Download and install the universal postscript printer driver from adobe.

3. Insert the CGM file into a Word document. Make sure Word has the CGM
graphics importer installed

4. Print the Word page to a PS file using the PS printer driver.

5. You can fix the PS bounding box in GhostView
