Operators

intersection_circle_contour_xld (Operator)

Name

intersection_circle_contour_xld — Calculate the intersection points of a circle or circular arc and an XLD contour

Signature

intersection_circle_contour_xld(Contour : : CircleRow, CircleColumn, CircleRadius, CircleStartPhi, CircleEndPhi, CirclePointOrder : Row, Column)

Description

intersection_circle_contour_xld calculates the intersection points of a circle or circular arc and the XLD Contour. The circle is defined by its center (CircleRow,CircleColumn) and its radius CircleRadius. In addition to that, a circular arc is characterized by the angle of the start point CircleStartPhi, the angle of the end point CircleEndPhi, and the point order CirclePointOrder along the boundary. If CirclePointOrder is set to 'positive', the circular arc is defined counterclockwise. If CirclePointOrder is set to 'negative', the circular arc is defined clockwise. The intersection points, if any, are returned in (Row,Column).

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Processed without parallelization.

Parameters

Contour (input_object)  xld_cont object

XLD contour.

CircleRow (input_control)  circle.center.y (real / integer)

Row coordinate of the center of the circle or circular arc.

CircleColumn (input_control)  circle.center.x (real / integer)

Column coordinate of the center of the circle or circular arc.

Radius of the circle or circular arc.

CircleStartPhi (input_control)  real (real)

Angle of the start point of the circle or circular arc [rad].

Default value: 0.0

CircleEndPhi (input_control)  real (real)

Angle of the end point of the circle or circular arc [rad].

Default value: 6.28318

CirclePointOrder (input_control)  string (string)

Point order along the circle or circular arc.

Default value: 'positive'

List of values: 'negative', 'positive'

Row (output_control)  point.y(-array) (real)

Row coordinates of the intersection points.

Column (output_control)  point.x(-array) (real)

Column coordinates of the intersection points.

Result

If the parameters are valid, the operator intersection_circle_contour_xld returns the value 2 (H_MSG_TRUE).
