I tried using the commands from the previous post:
xwd | xpr -device ps > foo.ps<http://foo.ps>

That worked fine for me when I made movies this way. I'm not sure what else to recommend.

But the output was bizarre: reversed and had some artifacts.

I can certainly use the mac screen capture tools, but I am needing an automated capability to capture the structure of several matrices (~1000) during a run.

Hello,

I am trying to save the matrix structure visualization from (-mat_view_draw) to a file (jpeg, ps, or anything else).
I saw the post: "help in capturing matrix patterns to files,"

The easiest thing to do is use screen capture for that window.

    Matt

but adding the options did not work for me:
 –mat_view_draw –draw_type ps

I have been trying to do this with the example file: ksp/examples/tutorials/ex1.c

I included "petscdraw.h"

$ mpiexec ex1 -mat_view_draw -draw_type ps
