[Paraview-developers] Catalyst error on SaveScreenshot

Thu Oct 26 03:19:41 EDT 2017

Hi Utkarsh,

Thanks for your quick reply; I am not generating my own editions but with your fix I can easily patch the catalyze.pi and json manifest files.

Best wishes,

Menno,

Here's a fix for the catalyst edition generation code:

  https://gitlab.kitware.com/paraview/paraview/merge_requests/1989

Are you generating your own editions? Let me know if you want me to pregenerate an updated edition with this fix for you.

This is indeed a bug. I suspect the Catalyst edition is missing the proxies used to save screenshot.

I've reported an issue here: https://gitlab.kitware.com/paraview/paraview/issues/17794

I can put together a quick fix once I get to work.

Hi,

So far I have linked our co-processing interface to the full source build of paraview, which works. In a bid to reduce the memory footprint and binary size I linked to the Catalyst edition “Base/Enable-Python/Essentials/Extras/Rendering-Base/Rendering-Base-Python”. The memory footprint is indeed reduced, so it seems worthwhile to use a Catalyst edition. When I try to save an image, however, the pipeline that works fine on the executable linked to the full ParaView build gives an error on the executable linked to the Catalyst build:

  File "<string>", line 2, in <module>
  File "coproc.py", line 180, in DoCoProcessing

  File "/home/mdeij/src/Catalyst/build/lib/site-packages/paraview/coprocessing.py", line 271, in WriteImages
    magnification=view.cpMagnification, quality=quality)
  File "/home/mdeij/src/Catalyst/build/lib/site-packages/paraview/simple.py", line 1071, in SaveScreenshot
    return _SaveScreenshotLegacy(filename, view=view, **params)
  File "/home/mdeij/src/Catalyst/build/lib/site-packages/paraview/simple.py", line 997, in _SaveScreenshotLegacy
    ImageQuality=imageQuality)
  File "/home/mdeij/src/Catalyst/build/lib/site-packages/paraview/simple.py", line 1080, in SaveScreenshot
    options = servermanager.misc.SaveScreenshot()
AttributeError: 'PVModule' object has no attribute 'SaveScreenshot'

Any idea why this happens and how to fix it? Am I using the right Edition(s)?

Thanks and best wishes,
