Add color LookupTable to a image print by vtkSMViewProxy->WriteImage
I'm using paraview proxy code to generate a slice of a cfd field, now it can set viewsize, show annotation by vtkSMProprttyHelper,and print an image by vtkSMViewProxy->WriteImage. But there is no color lookuptable in this image. In paraview application, when I choose a attribute data，the color lookupTable will be shown immediately. I don't know how to add a color LUT to the image.
