Transfor the shape of a region.
shape_trans transforms the shape of the input regions depending on the parameter Type:
'convex' Convex hull. 'ellipse' Ellipse with the same moments and area as the input region. 'outer_circle' Smallest enclosing circle. 'inner_circle' Largest circle fitting into the region. 'rectangle1' Smallest enclosing rectangle parallel to the coordinate axes. 'rectangle2' Smallest enclosing rectangle. 'inner_center' The point on the skeleton of the input region having the smallest distance to the center of gravity of the input region.
Region (input_object) |
region(-array) -> object |
Regions to be transformed. |
RegionTrans (output_object) |
region(-array) -> object |
Transformed regions. |
Type (input_control) |
string -> string |
Type of transformation. | |
Default value: 'convex' | |
List of values: 'convex', 'ellipse', 'outer_circle', 'inner_circle', 'rectangle1', 'rectangle2', 'inner_center' |
Let F be the area of the input region. Then the runtime complexity is O(F).
shape_trans returns TRUE if all parameters are correct. The behavior in case of empty input (no regions given) can be set via set_system(::'no_object_result',<Result>:). If necessary, an exception is raised.
