Herror ::clip_contours_xld ( Hobject Contours, Hobject *ClippedContours, const HTuple &Row1, const HTuple &Column1, const HTuple &Row2, const HTuple &Column2 ) HXLDContArray HXLDContArray::ClipContoursXld ( const HTuple &Row1, const HTuple &Column1, const HTuple &Row2, const HTuple &Column2 ) const

Clip an XLD contour.

::clip_contours_xld clips all XLD contours given in Contours, i.e., only contour points contained in the rectangle given by Row1, Column1, Row2, and Column2 are returned on output. If necessary, coutours are split, and several new contours are produced. The resulting contours are returned in ClippedContours.

Parameters

`Contours` (input_object)	xld_cont-array `->` Hobject: HXLDContArray
Contours to be clipped.

`ClippedContours` (output_object)	xld_cont(-array) `->` Hobject : HXLDCont(Array)*
Clipped contours.

`Row1` (input_control)	rectangle.origin.y `->` HTuple.long
Row coordinate of the upper left corner of the clip rectangle.
Default value: 0
Suggested values: 0, 500, 1000, 1500, 2000

`Column1` (input_control)	rectangle.origin.x `->` HTuple.long
Column coordinate of the upper left corner of the clip rectangle.
Default value: 0
Suggested values: 0, 500, 1000, 1500, 2000

`Row2` (input_control)	rectangle.corner.y `->` HTuple.long
Row coordinate of the lower right corner of the clip rectangle.
Default value: 512
Suggested values: 512, 1024, 1536, 2048

`Column2` (input_control)	rectangle.corner.x `->` HTuple.long
Column coordinate of the lower right corner of the clip rectangle.
Default value: 512
Suggested values: 512, 1024, 1536, 2048
