python - Converting numpy array svg image -

i have image want save in svg format. image in form of numpy array. although, there exist many methods save array in different image formats, not find 1 says done in svg.

any pointers or python script great!

thanks

since image in raster format, best can convert vector graphics program potrace. has python bindings pypotrace.

example code:

import numpy np import potrace  # make numpy array rectangle in middle data = np.zeros((32, 32), np.uint32) data[8:32-8, 8:32-8] = 1  # create bitmap array bmp = potrace.bitmap(data)  # trace bitmap path path = bmp.trace()  # iterate on path curves curve in path:     print "start_point =", curve.start_point     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
