INTViewer for Plugin Developers - Working with Polyline Data

Working with Polyline Data

A polyline data object is used to represent a set of 2D points.

Polyline files have the extension ".xpl" or ".txt". A polyline file can be loaded as follows:

    import com.interactive.intviewerapi.data.IData;

    import com.interactive.intviewerapi.data.polyline.IPolylineData;

    import com.interactive.intviewerapi.util.DialogManager;

...

        IData pol = null;

        try {

            pol = IData.factory.createNewInstance("/data/POLYLINE/LINE.xpl");

        } catch (Exception ex) {

            DialogManager.getDefault().showMessageDialog("Error loading Polyline file LINE.xpl.",

                    "Error Loading Polyline File", DialogManager.ERROR);

            return;

IPolylineData pol = new PolylineData("PolylineDataName", "INLINE", "XLINE");

Point2D newPoint = new Point(100, 200);

pol.addPoint(newPoint);

ArrayList<Point2D> points = pol.getPoints();
