HXLDCont HXLDDistTrans.ApplyDistanceTransformXld(HXLDCont contour)

Description

The operator apply_distance_transform_xldapply_distance_transform_xldApplyDistanceTransformXldApplyDistanceTransformXldApplyDistanceTransformXld determines for each point in ContourContourContourContourcontour the minimal distance to the reference contour using its XLD distance transform DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformID. The returned contour ContourOutContourOutContourOutContourOutcontourOut consists of ContourContourContourContourcontour with the attribute 'distance'"distance""distance""distance""distance" containing the calculated distances. They can be accessed by querying the attribute 'distance'"distance""distance""distance""distance" with get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldGetContourAttribXld.

Note that the distances depend on the parameters of create_distance_transform_xldcreate_distance_transform_xldCreateDistanceTransformXldCreateDistanceTransformXldCreateDistanceTransformXld: The distances are clipped to the maximum distance specified by the parameter MaxDistance. The parameter Mode determines whether the distances are calculated 'point_to_point'"point_to_point""point_to_point""point_to_point""point_to_point" or 'point_to_segment'"point_to_segment""point_to_segment""point_to_segment""point_to_segment".

Execution Information

Parameters

ContourContourContourContourcontour (input_object)  xld_cont(-array) objectHXLDContHXLDContHobject

Contour(s) for whose points the distances are calculated.

ContourOutContourOutContourOutContourOutcontourOut (output_object)  xld_cont(-array) objectHXLDContHXLDContHobject *

Copy of ContourContourContourContourcontour containing the distances as an attribute.

DistanceTransformIDDistanceTransformIDDistanceTransformIDDistanceTransformIDdistanceTransformID (input_control)  xld_dist_trans HXLDDistTrans, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Result

If all parameters are correct, the operator returns the value 2 (H_MSG_TRUE). Otherwise, an exception is raised.
