Class SmoothPolygonHighlighter

java.lang.Object
  jpicedt.graphic.view.highlighter.DefaultHighlighter
      jpicedt.graphic.view.highlighter.SmoothPolygonHighlighter

All Implemented Interfaces:

Highlighter

public class SmoothPolygonHighlighter
extends DefaultHighlighter

a Highlighter for SmoothPolygon. So far, it is based on AbstractCurveHighlighter, except where computing tangents is concerned, since for SmoothPolygon's, tangents are specified by polygon-point's rather than Bezier-points.

Since:

jPicEdt 1.4

Constructor Detail

SmoothPolygonHighlighter

public SmoothPolygonHighlighter(PicSmoothPolygon curve,
                                DefaultHighlighterFactory f)

construct a new Highlighter for the given smooth-polygon

Method Detail

getElement

public PicSmoothPolygon getElement()

Description copied from interface: Highlighter

returns the higlighted Element

Specified by:

getElement in interface Highlighter

Overrides:

getElement in class DefaultHighlighter

Returns:

the higlighted Element.

syncShape

protected void syncShape(double scale)

Synchronizes the highlighter's tangents with the model. This method is called from inside syncShape() only, and is overriden so as to compute tangents based on polygon's points rather than Bezier-points. Also compute the ``envelope'' polygon which is used for adding a new point (hitTest method).

Overrides:

syncShape in class DefaultHighlighter

Parameters:

scale - The current scale factor from-model-to-screen for the Graphics2D context ; this may be used to scale down line thickess, etc… so that e.g. barbells appear with the same size on the screen whatever the scale factor being set to the graphic context.
