Test, ob eine Region einen gegebenen Punkt enthält.
inside_region2 prüft, ob mindestens eine Eingaberegion aus Regions den Testpunkt (Row,Column) enthält.
In case of empty input (= no region) and set_system(::'no_object_result','true':) FALSE is returned (no region contains the pixel). The test pixel is not contained in an empty region (no pixel of the region corresponds to the pixel). If all regions are empty FALSE is also returned, i.e. an empty region behaves as if it did not exist.
Regions (input_object) |
region(-array) -> object |
Region(s) to be examined. |
Row (input_control) |
point.y -> integer |
Line index of the test pixel. | |
Default value: 100 | |
Range of values: 0 <= Row <= 512 (lin) | |
Minimum increment: 1 | |
Recommended increment: 1 |
Column (input_control) |
point.x -> integer |
Column index of the test pixel. | |
Default value: 100 | |
Range of values: 0 <= Column <= 512 (lin) | |
Minimum increment: 1 | |
Recommended increment: 1 |
Sei F die Fläche einer Region und N die Anzahl der Regionen, dann beträgt die mittlere Laufzeitkomplexität O(F) * N).
The operator inside_region2 returns the value TRUE if a region contains the test pixel. If this is not the case inside_region2 returns FALSE. The behavior in case of empty input (no input regions available) is set via the operator set_system(::'no_object_result',<Result>:). If necessary an exception is raised.
