Description

Method; returns a HalfEdge object on the contour of the selection.

Example

This example traverses all the contours of a selected shape and shows the coordinates of the

vertices in the Output panel:

// with a shape selected

var elt = fl.getDocumentDOM().selection[0];

elt.beginEdit();

var contourArray = elt.contours;

var contourCount = 0;

for (i=0; i<contourArray.length; i++)

{

var contour = contourArray[i];

contourCount++;

var he = contour.getHalfEdge();

var iStart = he.id;

var id = 0;

while (id != iStart)

{

// get the next vertex.

var vrt = he.getVertex();

var x = vrt.x;

var y = vrt.y;

fl.trace("vrt: " + x + ", " + y);

he = he.getNext();

id = he.id;

}

elt.endEdit();
