Description

clip_contours_xldclip_contours_xldClipContoursXldClipContoursXldClipContoursXld clips all XLD contours given in ContoursContoursContoursContourscontours, i.e., only contour points contained in the rectangle given by Row1Row1Row1Row1row1, Column1Column1Column1Column1column1, Row2Row2Row2Row2row2, and Column2Column2Column2Column2column2 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 ClippedContoursClippedContoursClippedContoursClippedContoursclippedContours.
