clip_contours

clip_contours_xld ( Contours : ClippedContours : Row1, Column1, Row2, Column2 : )

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 to be clipped.

`ClippedContours` (output_object)	xld_cont(-array) `->` object
Clipped contours.

`Row1` (input_control)	rectangle.origin.y `->` integer
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 `->` integer
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 `->` integer
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 `->` integer
