vtk_print help

[Troy Henderson]

I'm using Octave version 2.1.72 and Octaviz version 0.4.5 on Gentoo Linux.  I have successfully created a nice VTK figure in Octave with the following commands:

> x=rand(1,1000);
> y=rand(1,1000);
> z=sin(pi*x).*sin(pi*y);
> T=delaunay(x,y);
> vtk_trisurf(T,x,y,z);

I would like to print this figure, but when I do

> vtk_print('foo.jpg','-djpeg')

I get a garbled image in that it doesn't take a "snapshot" of the VTK window.  Furthermore, I'm more interested in having a EPS/PDF graphic.  I try to do this by:

> vtk_print('foo.eps')

I get the following error(s):

error: `vtkGL2PSExporter' undefined near line 110 column 9
error: evaluating assignment expression near line 110, column 7
error: evaluating if command near line 109, column 3
error: called from `vtk_print' in file `/usr/share/octave/2.1.72/site/m/octaviz/vtk_print.m'

Can anyone shed some insight into this problem, and more importantly, offer a solution.

Thanks!

Hi Troy,

can you make the images available (build logs might be necessary as well)? 

Do you have a file
  vtkGL2PSExporter.oct
in your Octaviz build?

I figured out what the problem was.  I didn't have GL2PS built into VTK.  Adding

-DVTK_USE_GL2PS:BOOL=ON

to CMAK_VARIABLES in VTK did the trick.  Once I added that and recompiled VTK, I had to recompile Ocativz.
