gen_region_contour_xldgen_region_contour_xldGenRegionContourXldgen_region_contour_xldGenRegionContourXldGenRegionContourXld — Create a region from an XLD contour.
Herror gen_region_contour_xld(const Hobject Contour, Hobject* Region, const char* Mode)
Herror T_gen_region_contour_xld(const Hobject Contour, Hobject* Region, const Htuple Mode)
gen_region_contour_xldgen_region_contour_xldGenRegionContourXldgen_region_contour_xldGenRegionContourXldGenRegionContourXld creates a region RegionRegionRegionRegionRegionregion from a
subpixel XLD contour ContourContourContourContourContourcontour. The contour is sampled
according to the Bresenham algorithm and influenced by the parameter
'neighborhood'"neighborhood""neighborhood""neighborhood""neighborhood""neighborhood" of the operator set_systemset_systemSetSystemset_systemSetSystemSetSystem. Open contours
are closed before converting them to regions. Finally, the parameter
ModeModeModeModeModemode defines whether the region is filled up ('filled'"filled""filled""filled""filled""filled")
or returned by its contour ('margin'"margin""margin""margin""margin""margin").
Please note that the coordinates of the contour points are rounded
to their nearest integer pixel coordinates during the conversion.
This may lead to unexpected results when passing the contour
obtained by the operator gen_contour_region_xldgen_contour_region_xldGenContourRegionXldgen_contour_region_xldGenContourRegionXldGenContourRegionXld to
gen_region_contour_xldgen_region_contour_xldGenRegionContourXldgen_region_contour_xldGenRegionContourXldGenRegionContourXld: When setting ModeModeModeModeModemode of
gen_contour_region_xldgen_contour_region_xldGenContourRegionXldgen_contour_region_xldGenContourRegionXldGenContourRegionXld to 'border'"border""border""border""border""border", the input region
of gen_contour_region_xldgen_contour_region_xldGenContourRegionXldgen_contour_region_xldGenContourRegionXldGenContourRegionXld and the output region of
gen_region_contour_xldgen_region_contour_xldGenRegionContourXldgen_region_contour_xldGenRegionContourXldGenRegionContourXld differ. For example, let us assume
that the input region of gen_contour_region_xldgen_contour_region_xldGenContourRegionXldgen_contour_region_xldGenContourRegionXldGenContourRegionXld consists of
the single pixel (1,1). Then, the resulting contour that is
obtained when calling gen_contour_region_xldgen_contour_region_xldGenContourRegionXldgen_contour_region_xldGenContourRegionXldGenContourRegionXld with
ModeModeModeModeModemode set to 'border'"border""border""border""border""border" consists of the five points
(0.5,0.5), (0.5,1.5), (1.5,1.5), (1.5,0.5), and (0.5,0.5).
Consequently, when passing this contour again to
gen_region_contour_xldgen_region_contour_xldGenRegionContourXldgen_region_contour_xldGenRegionContourXldGenRegionContourXld, the resulting region consists of the
points (1,1), (1,2), (2,2), and (2,1).
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
