Description
Method; returns a HalfEdge object
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;
{
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();
