Save a fenicstools cross section directly to png file

Question

Is there a way to (automatically) save a 2D cross section directly to a png file?
I know I can save it to vtk, then open paraview and save a png. Is there a way to automate this process?f

Answer 1

Perhaps you can use matplotlib, see for instance :
