with certain texts, vtkTextActor3D generates DisplayExtent / WholeExtent ERROR
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Running the attached Python example yields the following error:
RuntimeError: ERROR: In ......\archive\VTK\Filtering\vtkStreamingDemandDrivenP ipeline.cxx, line 698 vtkStreamingDemandDrivenPipeline (017CF3C8): The update extent specified in the information for output port 0 on algorithm vtkTrivialProducer(017D2FF0) is 0 255 0 63 0 0, which is outside the whole extent 0 255 0 31 0 0.
This is with the text 'what hg'. With 'what h', there's no error.
This is strange, because in vtkTextActor3D::UpdateImageActor(), these two extents are set to equal. At the moment, I can work around the problem by setting them again after UpdateImageActor, but this is not a good fix.
