Hi,
I have a custom ParaView reader plugin that I've written, which works as
expected when loaded and used through the GUI, but I'm having trouble getting
it to work with pvbatch. I have tried a couple of different approaches, with
varying degrees of success. The one that gets furthest is this..
Using the GUI I load the plugin. I'm running in client/server mode, so load
the plugin for both sides. I then load a custom data file using this plugin.
An unstructured grid is generated and rendered, this works as expected. I then
save the state.
If I relaunch ParaView and the pvserver, again load the plugin on both sides,
and load the state file that I just saved, the data is loaded and rendered. So
far, so good.
For pvbatch I try running with the following script:
------------------
try: paraview.simple
except: from paraview.simple import *
servermanager.LoadPlugin('/home/insley/libMyCustomReader.so')
servermanager.LoadState("/home/insley/my_state_flle.pvsm")
curView = GetRenderView()
SetActiveView(curView)
curView.ViewSize = [1920, 1080]
curView.StillRender()
WriteImage("/home/insley/test_image.png")
-----------------
I call DebugOn() in the constructor of my class, and see lots of output from
pvbatch so it seems that the plugin is getting loaded correctly. I see output
from the RequestInformation() in my reader class, but I do not see anything
from the RequestData() method. So it appears that RequestData() is never
called, and the actual data is not being read from disk. Is there something
additional that I need to do to cause that to be invoked?
After the RequestInformation() output I see a number of printouts about my
class being Registered and UnRegistered by other classes
(vtkClientServerInterpreter, vtkCompositeDataPipeline, etc) and the output from
my class' destructor.
A black image (of resolution 1920x1080) is saved to /home/insley/test_image.png
Any insight that folks could provide would be much appreciated.
Thanks,
joe.
