Quick Start

How do I...

contour an image?

from contourheightmap import ContourHeightmap

c = ContourHeightmap()
c.contour("path/to/heightmap.png")

Result will be in output.png and output.svg

provide an output filename?

from contourheightmap import ContourHeightmap

c = ContourHeightmap()
c.contour("path/to/heightmap.png", "path/to/output.png")

Output will also be in path/to/output.svg

output a contoured image from the command line?
