![]() ![]() Raise Exception( 'Inkscape error: ' + (err or '?') )įor example, when running a particular job on my Mac OS system, out ended up being: Background RRGGBBAA: ffffff00Īrea 0:0:339:339 exported to 100 x 100 pixels (72.4584 dpi) # Maybe do something with stderr output that is in # Maybe do something with stdout output that is in Out, err = p.communicate() # Waits for process to terminate # Below, and are strings or, derived from stdout and stderr. P = subprocess.Popen( cmd_list, stdout=subprocess.PIPE, stderr=subprocess.PIPE ) Divert output that normally goes to stdout or stderr. import subprocess # May want to use subprocess32 insteadĬmd_list = [ '/full/path/to/inkscape', '-z', The output is captured in two string variables, out and err. Note that it suppresses certain crufty output that Inkscape writes to the console (specifically, stderr and stdout) during normal error-free operation. Here is an approach where Inkscape is called by Python.

Svg_surface = cairo.SVGSurface(None, width, height) Assuming your SVG is not exactly 256x256 pixels, the desired output, you can read in the SVG to a Cairo context using rsvg and then scale it and write to a PNG. Using pycairo and librsvg I was able to achieve SVG scaling and rendering to a bitmap.

This is all the code it takes: with ( blob=svg_file.read(), format="svg" ) as image: ![]()
