This version runs faster, has more color quantization options (median-cut, adaptive spatial subdivision, and neuquant), supports dithering*, prescales the image for better quality, makes available several of potrace's options, and can use an external palette instead of color quantizing. Edit: I don't know what happens to Inkscape users on Windows who redefine the global %PATH% variable to point to a system-wide custom Python 3.x installation (AFAIK untested with Inkscape 0.48.x, which includes its own python 2.6.5 executable as well as the modules lxml 2.2.4 and numpy 1.4.1). (Note: Inkscape's extensions haven't been migrated to fully support Python 3.x - whoever (on linux) changes the system-wide default python version to 3 without taking care that Inkscape still spawns python-2.x for the bundled extensions, might have issues with failing extensions (input/output as well as effects)).

You won't offer a version compatible with Python 2.7? I would have been interested in testing the script on OS X 10.7.2 - even wrote a MacPorts portfile for pngnq - only to realize later-on that it would force me to install a (potientally conflicting) Python version. You need to install Python 3.2 or later, and also the lxml library for that version of Python. Ukurereh wrote:Here it is, a Python script to trace a whole directory of color images at once.
