How can I export a VTK screenshot to a PDF or a vectorized image?

I wrote a python script to render a VTK object and save its figure as PNG using the vtkPNGWriter() functions. Is there a way to save it as a PDF or a svg file?

Solution

  • It is possible to export a PDF image of the render window using the function vtk.vtkGL2PSExporter(). Here a working snippet of code:

    pdfExporter = vtk.vtkGL2PSExporter()
pdfExporter.SetRenderWindow(render_window)


outputFilename = "file_name"

pdfExporter.SetFileFormatToPDF()  #save as pdf
pdfExporter.SetFilePrefix(outputFilename)
pdfExporter.Write()
