Translate a region.
::move_region translates the input regions by the vector given by (Row, Column). If necessary, the resulting regions are clipped with the current image format.
|
Region (input_object) |
region(-array) -> Hobject: HRegion(Array) |
| Region(s) to be moved. | |
|
RegionMoved (output_object) |
region(-array) -> Hobject * : HRegion(Array) |
| Translated region(s). | |
| Number of elements: RegionMoved == Region | |
|
Row (input_control) |
point.y -> HTuple.long |
| Row coordinate of the vector by which the region is to be moved. | |
| Default value: 30 | |
| Suggested values: -128, -64, -32, -16, -10, -8, -4, -2, -1, 0, 1, 2, 4, 5, 8, 10, 16, 32, 64, 128 | |
| Typical range of values: -512 <= Row <= 512 (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 10 | |
|
Column (input_control) |
point.x -> HTuple.long |
| Row coordinate of the vector by which the region is to be moved. | |
| Default value: 30 | |
| Suggested values: -128, -64, -32, -16, -10, -8, -4, -2, -1, 0, 1, 2, 4, 5, 8, 10, 16, 32, 64, 128 | |
| Typical range of values: -512 <= Column <= 512 (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 10 | |
Let F be the area of the input region. Then the runtime complexity is O(F).
::move_region always returns the value 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 handling is raised.
