for shp:= Low(TIEShape) to High(TIEShape) do begin
for i:= 0 to TIEEllipse(shp). := Low to High do begin

end;
end;

Hi Andy

There is not an easy way to do that with a TIEShapeLayer.

If you create a TIEPolyline layer and fill its points using a TIEShape:

https://www.imageen.com/help/TIEPolylineLayer.SetPoints.html

Then you can get the centroid using:

https://www.imageen.com/help/TIEPolylineLayer.CalculateCentroid.html


Otherwise you can calculate it yourself with:

IEGenerateShapePoints(); (in iexCanvasUtils.pas)
and
IECalcPolygonCentroid(); (in hyieutils.pas)

But that is unsupported.
