Store input lines as regions.
The operator gen_region_line stores the given lines (with starting point [BeginRow,BeginCol] and ending point [EndRow, EndCol]) as region.
|
RegionLines (output_object) |
region(-array) -> object |
| Created regions. | |
|
BeginRow (input_control) |
line.begin.y(-array) -> integer |
| Line coordinates of the starting points of the input lines. | |
| Default value: 100 | |
| Suggested values: 10, 50, 100, 200, 300, 400 | |
| Typical range of values: -oo <= BeginRow <= -oo (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 1 | |
|
BeginCol (input_control) |
line.begin.x(-array) -> integer |
| Column coordinates of the starting points of the input lines. | |
| Default value: 50 | |
| Suggested values: 10, 50, 100, 200, 300, 400 | |
| Typical range of values: -oo <= BeginCol <= -oo (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 1 | |
|
EndRow (input_control) |
line.end.y(-array) -> integer |
| Line coordinates of the ending points of the input lines. | |
| Default value: 150 | |
| Suggested values: 50, 100, 200, 300, 400, 500 | |
| Typical range of values: -oo <= EndRow <= -oo (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 1 | |
|
EndCol (input_control) |
line.end.x(-array) -> integer |
| Column coordinates of the ending points of the input lines. | |
| Default value: 250 | |
| Suggested values: 50, 100, 200, 300, 400, 500 | |
| Typical range of values: -oo <= EndCol <= -oo (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 1 | |
The operator gen_region_line always returns the value 2 (H_MSG_TRUE). The clipping according to the current image format is determined by the operator set_system('clip_region',<'true'/'false'>).
gen_region_line is reentrant and processed without parallelization.
