I'm trying to draw vector graphics on a canvas using Python's Tkinter and I was excited when I noticed that canvases have a postscript() method that can save the contents of the canvas to a Postscript file and it's fairly trivial to losslessly convert SVG to EPS.
My question is this: can it do the reverse?  Can I take a postscript file from the disk and unpack it onto the canvas?  Is Tk a powerful enough graphics toolkit for that?
or would I be better off just rendering the svg down to a GIF image (or parsing the EPS file using PIL and converting it to a pixel array that way) and displaying that?
Can a Tk canvas import a postscript file and display it?

No, it cannot.
