Default Scripting with trace: cameraview

Dear all,

I'm writing a script to automate some tasks when post-processing with ParaView 5.0.0. I use Tools > Start Trace to convert the mouse movements to Python code. However, the tracing does not work / does not generate code when loading a cameraview (.pvcc file) and I don't seem to be the only one who has had this problem.

Has anyone have found a workaround solution or found the code equivalent?

I forgot to post the solution that I came up with some time ago:

Code:
    # Read pvcc file
    A = []
    with open(top_path + '/' + pvccfile) as fileobject:
        A = fileobject.read()
    
    B = ''.join(A)
    C = B.replace('\n','')
    
    # CameraPosition
    match_pos = re.findall('<Property name="CameraPosition"(.*)<Property name="CameraFocalPoint"',C)
    
    xpos = re.findall('<Element index="0" value="(.*)"/>(.*)<Element index="1"',match_pos[0])
    ypos = re.findall('<Element index="1" value="(.*)"/>(.*)<Element index="2"',match_pos[0])
    zpos = re.findall('<Element index="2" value="(.*)"/>',match_pos[0])
    xpos = float(xpos[0][0])
    ypos = float(ypos[0][0])
    zpos = float(zpos[0])
    
    # CameraFocalPoint
    match_foc = re.findall('<Property name="CameraFocalPoint"(.*)<Property name="CameraViewUp"',C)
    
    xfoc = re.findall('<Element index="0" value="(.*)"/>(.*)<Element index="1"',match_foc[0])
    yfoc = re.findall('<Element index="1" value="(.*)"/>(.*)<Element index="2"',match_foc[0])
    zfoc = re.findall('<Element index="2" value="(.*)"/>',match_foc[0])
    xfoc = float(xfoc[0][0])
    yfoc = float(yfoc[0][0])
    zfoc = float(zfoc[0])
    
    # CameraViewUp
    match_up = re.findall('<Property name="CameraViewUp"(.*)<Property name="CenterOfRotation"',C)
    
    xup = re.findall('<Element index="0" value="(.*)"/>(.*)<Element index="1"',match_up[0])
    yup = re.findall('<Element index="1" value="(.*)"/>(.*)<Element index="2"',match_up[0])
    zup = re.findall('<Element index="2" value="(.*)"/>',match_up[0])
    xup = float(xup[0][0])
    yup = float(yup[0][0])
    zup = float(zup[0])
    
    # CenterOfRotation
    match_rot = re.findall('<Property name="CenterOfRotation"(.*)<Property name="RotationFactor"',C)
    
    xrot = re.findall('<Element index="0" value="(.*)"/>(.*)<Element index="1"',match_rot[0])
    yrot = re.findall('<Element index="1" value="(.*)"/>(.*)<Element index="2"',match_rot[0])
    zrot = re.findall('<Element index="2" value="(.*)"/>',match_rot[0])
    xrot = float(xrot[0][0])
    yrot = float(yrot[0][0])
    zrot = float(zrot[0])
    
    # RotationFactor
    match_fac = re.findall('<Property name="RotationFactor"(.*)<Property name="CameraViewAngle"',C)
    rotation_factor = re.findall('<Element index="0" value="(.*)"/>',match_fac[0])
    rotation_factor = float(rotation_factor[0])
    
    # CameraViewAngle
    match_ang = re.findall('<Property name="CameraViewAngle"(.*)<Property name="CameraParallelScale"',C)
    camera_ang = re.findall('<Element index="0" value="(.*)"/>',match_ang[0])
    camera_ang = float(camera_ang[0])
    
    # CameraParallelScale
    match_sca = re.findall('<Property name="CameraParallelScale"(.*)<Property name="CameraParallelProjection"',C)
    camera_sca = re.findall('<Element index="0" value="(.*)"/>',match_sca[0])
    camera_sca = float(camera_sca[0])
    
    # CameraParallelProjection
    match_prj = re.findall('<Property name="CameraParallelProjection"(.*)<Domain',C)
    camera_proj = re.findall('<Element index="0" value="(.*)"/>',match_prj[0])
    camera_proj = int(camera_proj[0])
    
    renderView1.CameraViewUp = [xup, yup, zup]
    renderView1.CameraPosition = [xpos, ypos, zpos]
    renderView1.CenterOfRotation = [xrot, yrot, zrot]
    renderView1.RotationFactor = rotation_factor
    renderView1.CameraViewAngle = camera_ang
    renderView1.CameraParallelScale = camera_sca
    renderView1.CameraParallelProjection = camera_proj
    renderView1.CameraFocalPoint = [xfoc, yfoc, zfoc]
