clip_contours_xldclip_contours_xldClipContoursXldClipContoursXldclip_contours_xld (Operator)
Name
clip_contours_xldclip_contours_xldClipContoursXldClipContoursXldclip_contours_xld — Clip an XLD contour.
Signature
Herror clip_contours_xld(const Hobject Contours, Hobject* ClippedContours, const Hlong Row1, const Hlong Column1, const Hlong Row2, const Hlong Column2)
Herror T_clip_contours_xld(const Hobject Contours, Hobject* ClippedContours, const Htuple Row1, const Htuple Column1, const Htuple Row2, const Htuple Column2)
Description
clip_contours_xldclip_contours_xldClipContoursXldClipContoursXldClipContoursXldclip_contours_xld clips all XLD contours given in
ContoursContoursContoursContourscontourscontours, i.e., only contour points contained in the
rectangle given by Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2,
and Column2Column2Column2Column2column2column_2 are returned on output. Note, that the rectangle
behaves like a region, i.e., the rectangle encloses the pixels completely.
If necessary, contours
are split, and several new contours are produced. The resulting
contours are returned in ClippedContoursClippedContoursClippedContoursClippedContoursclippedContoursclipped_contours.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
