Description

transpose_regiontranspose_regionTransposeRegiontranspose_regionTransposeRegionTransposeRegion reflects a region about a point. The fixed point is given by ColumnColumnColumnColumnColumncolumn and RowRowRowRowRowrow. The image P' of a point P is determined by the following requirement:

If P = S, then P' = S, i.e., the point S is the fixed point of the mapping. If , S is the center point of a line segment connecting P and P'. Therefore, the following equations result:

If RowRowRowRowRowrow and ColumnColumnColumnColumnColumncolumn are set to the origin, the in morphology often used transposition results. Hence transpose_regiontranspose_regionTransposeRegiontranspose_regionTransposeRegionTransposeRegion is often used to reflect (transpose) a structuring element.

Result

transpose_regiontranspose_regionTransposeRegiontranspose_regionTransposeRegionTransposeRegion returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:

Otherwise, an exception is raised.
