ConvertToArcPolyline

Description

Convert, within a tolerance, the input polyline into an polyline that uses arcs for the curves.

FUNCTION ConvertToArcPolyline(
				hPolygon : HANDLE;
				dFuzz    : REAL): HANDLE;
def vs.ConvertToArcPolyline(hPolygon, dFuzz):
    return HANDLE

Parameters

Name Type Description
hPolygon HANDLE
dFuzz REAL

Remarks

(c, 2022.02.02) This routine must be updated, it still doesn't recognize Radius vertexes.

As of VW 2022 the routine behaves on vertexes as such:

  • corner: preserved
  • arc: preserved only on dFuzz = 0, otherwise they turn into corner, which is truly strange, since the purpose IS to create arc vertexes
  • radius: ignored, turn into corner
  • cubic: turn into arc
  • bezier: turn into arc

Examples

VectorScript

PROCEDURE Test;
VAR
    polyObj, newPolyObj : HANDLE;
	
BEGIN
    { select a polyline }
    polyObj := FSActLayer;
    IF polyObj <> NIL THEN BEGIN
        newPolyObj := ConvertToArcPolyline(polyObj, 0);
        SetDSelect(polyObj);
    END;
END;
Run(Test);

Python

# select a polyline
polyObj = vs.FSActLayer()
if polyObj != vs.Handle( 0 ):
	newPolyObj = vs.ConvertToArcPolyline(polyObj, 0)
	vs.SetDSelect(polyObj)
