potrace Python bindings
Project description
These bindings provide an object oriented API to the potrace library.
Example usage
The bindings work with input images represented as numpy arrays:
import numpy as np import potrace # Make a numpy array with a rectangle in the middle data = np.zeros((32, 32), np.uint32) data[8:32-8, 8:32-8] = 1 # Create a bitmap from the array bmp = potrace.Bitmap(data) # Trace the bitmap to a path path = bmp.trace() # Iterate over path curves for curve in path: print "start_point =", curve.start_point for segment in curve: print segment end_point_x, end_point_y = segment.end_point if segment.is_corner: c_x, c_y = segment.c else: c1_x, c1_y = segment.c1 c2_x, c2_y = segment.c2
Installation
Make sure you have the agg and potrace development packages installed (libagg-dev and libpotrace-dev on ubuntu) and run:
python setup.py install
