split_skeleton_region — Split lines represented by one pixel wide, non-branching regions.
split_skeleton_region splits lines represented by one pixel wide, non-branching regions into shorter lines based on their curvature. A line is split if the maximum distance of a point on the line to the line segment connecting its end points is larger than MaxDistance (split & merge algorithm). However, not the approximating lines are returned, but rather the original lines split into several output regions.
The input regions must represent non-branching lines, that is single branches of the skeleton.
Input lines (represented by 1 pixel wide, non-branching regions).
Maximum distance of the line points to the line segment connecting both end points.
Default value: 3
Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Typical range of values: 1 ≤ MaxDistance ≤ 500 (lin)
Minimum increment: 1
Recommended increment: 1

split_skeleton_region always returns the value 2 (H_MSG_TRUE). The behavior in case of empty input (no regions given) can be set via set_system('no_object_result',<Result>), the behavior in case of an empty input region via set_system('empty_region_result',<Result>), and the behavior in case of an empty result region via set_system('store_empty_region',<'true'/'false'>). If necessary, an exception is raised.
