Approx Vector
This layer (approx_vector
) approximates vector figures: lines and polygons.
The operation decreases number of vertices with Douglas-Peucker algorithm.
Example:
{ "action": "approx_vector", "src": [ "$sample1" ], "dst": "$sample2", "settings": { "classes": [ "my_line", "interesting_poly" ], "epsilon": 3 } }
Settings¶
classes
— list of classes to apply transformation. Only classes with shape "line" or "polygon" are allowed.epsilon
— approximation accuracy (maximum distance between the original curve and its approximation).
