Add the result of a hit-or-miss operation to a region (using a Golay structuring element).
::thickening_golay performs a thickening of the input regions using morphological operations and structuring elements from the Golay alphabet. The operator first applies a hit-or-miss-transformation to Region (cf.::hit_or_miss_golay), and then adds the detected points to the input region. The following structuring elements are available:
'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k'.
The rotation number Rotation determines which rotation of the element should be used. The Golay elements, together with all possible rotations, are described with the operator ::golay_elements.
Not all values of Rotation are valid for any Golay element.

| Regions to be processed. | |

GolayElement (input_control) |
string -> HTuple.char * |
| Structuring element from the Golay alphabet. | |
| Default value: 'h' | |
| List of values: 'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k' | |

Rotation (input_control) |
integer -> HTuple.long |
| Rotation of the Golay element Depending on the element, not all rotations are valid. | |
| Default value: 0 | |
| List of values: 0, 2, 4, 6, 8, 10, 12, 14, 1, 3, 5, 7, 9, 11, 13, 15 | |
Let F be the area of an input region. Then the runtime complexity for one region is:
O(6 * sqrt(F)) .
::thickening_golay returns H_MSG_TRUE if all parameters are correct. The behavior in case of empty or no input region can be set via:
a) no region: set_system('no_object_result',<RegionResult>)
b) empty region: set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
