Thanks Burlen! Obviously, my ParaView Python fu is weak. I tried to merge this code into Python created by the trace recorder, but couldn't. Say a person does the following (which is sort of what my customer is doing) :
* Trace recorder on. * Wavelet. Apply. Surface. RTData. * Color Editor/ Presets/ Blue to Red Rainbow. * Trace Recorder off. The line setting Blue to Red Rainbow doesn't get recorded. What code would I paste in there? Here is the incorrect trace: #### import the simple module from the paraview from paraview.simple import * #### disable automatic camera reset on 'Show' paraview.simple._DisableFirstRenderCameraReset() # create a new 'Wavelet' wavelet1 = Wavelet() # get active view renderView1 = GetActiveViewOrCreate('RenderView') # uncomment following to set a specific view size # renderView1.ViewSize = [856, 797] # show data in view wavelet1Display = Show(wavelet1, renderView1) # trace defaults for the display properties. wavelet1Display.Representation = 'Outline' wavelet1Display.ColorArrayName = ['POINTS', ''] wavelet1Display.ScalarOpacityUnitDistance = 1.7320508075688779 wavelet1Display.Slice = 10 # reset view to fit data renderView1.ResetCamera() # change representation type wavelet1Display.SetRepresentationType('Surface') # set scalar coloring ColorBy(wavelet1Display, ('POINTS', 'RTData')) # rescale color and/or opacity maps used to include current data range wavelet1Display.RescaleTransferFunctionToDataRange(True) # show color bar/color legend wavelet1Display.SetScalarBarVisibility(renderView1, True) # get color transfer function/color map for 'RTData' rTDataLUT = GetColorTransferFunction('RTData') rTDataLUT.RGBPoints = [37.35310363769531, 0.231373, 0.298039, 0.752941, 112.04112243652344, 0.865003, 0.865003, 0.865003, 186.72914123535156, 0.705882, 0.0156863, 0.14902] rTDataLUT.ScalarRangeInitialized = 1.0 # get opacity transfer function/opacity map for 'RTData' rTDataPWF = GetOpacityTransferFunction('RTData') rTDataPWF.Points = [37.35310363769531, 0.0, 0.5, 0.0, 186.72914123535156, 1.0, 0.5, 0.0] rTDataPWF.ScalarRangeInitialized = 1 #### saving camera placements for all active views # current camera placement for renderView1 renderView1.CameraPosition = [0.0, 0.0, 66.92130429902464] renderView1.CameraParallelScale = 17.320508075688775 #### uncomment the following to render all views # RenderAllViews() # alternatively, if you want to write images, you can use SaveScreenshot(...).

For example see code between # marks below. There are a few other conveniences for working with the builtin tables as well, see this recipe<http://www.paraview.org/Wiki/ParaView/Python/Lookup_tables> w = Wavelet() w_rep = Show(w) w_rep.Representation = 'Surface' # w_rep.ColorArrayName = 'RTData' w_arr = w.PointData.GetArray('RTData') w_rep.LookupTable = AssignLookupTable(w_arr, 'Rainbow Blended White') # Render().ResetCamera() Burlen On 03/16/2015 03:14 PM, Scott, W Alan wrote: I have a user that needs to change the ParaView preset from default (cool to warm) to another ParaView preset (Blue to Red Rainbow). He wants to do this in a python trace. So, he used the trace recorder to record his steps. Unfortunately, changing presets is not recorded with the trace recorder. I have written this issue up as bug number http://www.paraview.org/Bug/view.php?id=15116, but need to give the user the code that would have/ should have been produced. Does anyone have the python code that changes presets? Thanks all!
