<p class="MsoNormal" style="margin-bottom:12.0pt">I'm attaching a couple of files that you can use to test if you have the proper fix for your branch. Run the python script with "mpirun -np 8 bin/pvbatch -sym parallelpythontest.py". If you get the same results
then you don't have the fix yet for the image issue. Note that parallelpythontest2.png isn't getting colored properly while parallelpythontest.png is.<br>

<br>
There were a couple of issues when saving images. One was for saving charts and maybe 2d views. The other one was for when some processes didn't have any points or cells. Looking at your stack traces I don't think it's the latter since that would fail in
the python script and give a warning in there. Any chance you could test with the paraview's current master branch?<br>
<br>
Are you using a python script to drive the coprocessing? If yes, can you share it?<br>

<br>
There was a problem with the SaveImageOnProcess Zero which caused exactly this some time ago. I'm using a branch of mine derived from the v3.12.0 tag, but I cherry picked Andy's patch from kitware/master or wherever that was mentioned a few days ago -are there
othe fixes on master/next that I might beneeding?<br>
<br>
Any ideas. The pipeline is a contour of some image data on N processes. Pretty Simple.<br>
<br>
Any help appreciated.<br>
<br>
thanks<br>
