potracer 0.0.4

Python Potrace

Python Potrace

Pure Python Port of Potrace. This is a python port of Peter Selinger's Potrace (based on 1.16 code).

This port is needed because many python hooks to the original code such as pypotrace have installation issues and compilation problems with some OSes. This potrace is written in pure python and will be compatible with basically anything.

Installing

To install or use as a requirement:

• pip install potracer

Potrace-CLI

If you wish to use the Command Line Interface that is stored in a sister project potrace-cli (https://github.com/tatarize/potrace-cli). This can be installed with:

• pip install potracer[cli]

or:

• pip install potrace-cli

The cli project contains valid console script entrypoints for potrace. If you install the command-line package it will add potracer to your console scripts. Note the -r suffix so that it does not interfere with potrace that may be otherwise installed.

Requirements

• numpy: for bitmap structures.

Speed

Being written in python this code may be about 500x slower than the pure-c potrace. It is however fast enough for general use.

Parallel Projects

This project intentionally duplicates a considerable amount of the API of pypotrace such that this library can be used as a drop-in replacement.

This library offers CLI potrace as an optional package, to permit performing potrace commands from the commandline.
