Name
test_region_pointtest_region_pointTestRegionPointtest_region_pointTestRegionPointTestRegionPoint — Test if the region contains a given point.
If an array of regions and one test point is provided,
test_region_pointtest_region_pointTestRegionPointtest_region_pointTestRegionPointTestRegionPoint tests if at least one input region of
RegionsRegionsRegionsRegionsRegionsregions contains the single test point given in
(RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn). If this is the case, IsInsideIsInsideIsInsideIsInsideIsInsideisInside is
set to TRUE, else to FALSE. Alternatively, if a single region and several
test points are provided, test_region_pointtest_region_pointTestRegionPointtest_region_pointTestRegionPointTestRegionPoint tests if at least
one of the test points (given in RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn) is contained
in the input region given in RegionsRegionsRegionsRegionsRegionsregions.
If this is the case, IsInsideIsInsideIsInsideIsInsideIsInsideisInside is set to TRUE, otherwise it is set
to FALSE. If (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn) are real-valued, rounding is
performed internally since regions are pixel precise.
The test pixel is not contained in an empty region
(no pixel of the region corresponds to the pixel).
If all regions are empty IsInsideIsInsideIsInsideIsInsideIsInsideisInside is set to
FALSE.
In case of an empty input object (empty tuple) RegionsRegionsRegionsRegionsRegionsregions and
set_system('no_object_result','true')set_system("no_object_result","true")SetSystem("no_object_result","true")set_system("no_object_result","true")SetSystem("no_object_result","true")SetSystem("no_object_result","true"), an empty tuple is
returned in IsInsideIsInsideIsInsideIsInsideIsInsideisInside. If
set_system('no_object_result','false')set_system("no_object_result","false")SetSystem("no_object_result","false")set_system("no_object_result","false")SetSystem("no_object_result","false")SetSystem("no_object_result","false") was set, an exception is
raised.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Region(s) to be examined.

Row index of the test pixel(s).
Default value: 100
Column index of the test pixel(s).
Number of elements: Row == Column
Default value: 100
If F is the area of one region, N is the number of regions, and M is
the number of test points, the runtime complexity is
O(ln(sqrt(F)) * N) in the case of one test point and several regions and
O(ln(sqrt(F)) * M) in the case of one region and several test points.
The operator test_region_pointtest_region_pointTestRegionPointtest_region_pointTestRegionPointTestRegionPoint returns the value 2 (H_MSG_TRUE)
if the parameters are correct.
The behavior in case of an empty object is
set via the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
If necessary, an exception is raised.
