gen_cross_contour_xld — Generate one XLD contour in the shape of a cross for each input point.
gen_cross_contour_xld generates an XLD contour in the shape of a cross for each input point (Row,Col). Conceptually, the contour consists of two lines of length Size, which intersect exactly in the input point. Their orientation is determined by Angle. The cross is returned in Cross. If there are multiple points to be processed, their coordinates must be passed as tuples.
Generated XLD contours.
Row coordinates of the input points.
Column coordinates of the input points.
Restriction: number(Col) == number(Row)
Length of the cross bars.
Default value: 6.0
Suggested values: 4.0, 6.0, 8.0, 10.0
Restriction: 0.0 <= Size
Orientation of the crosses.
Default value: 0.785398
Suggested values: 0.0, 0.785398
gen_cross_contour_xld returns 2 (H_MSG_TRUE) if all parameters are correct and no error occurs during execution.
