#3619 closed enhancement (fixed)

Polygonize should have a connectedness parameter

Description

Currently polygonize defaults to 4-connectedness and there is no way to change that. I suggest we use the Options parameter for that. Attached is a tested diff which achieves just this.

Component: default → Algorithms
Keywords: polygonize added
Milestone: → 1.8.0
Owner: changed from warmerdam to ilucena
Version: unspecified → svn-trunk

Ivan,

please incorporate this patch and:

  • Update the GDALPolygonize() docs to mention the new parameter.
  • Update the autotest/alg/polygonize.py test to include 8-connectedness testing.

This should only be in trunk for now I think.
