Field Details

backgroundColor

protected Color backgroundColor

Stored costructor parameter

rectMap

protected SyntaxGraph.RectMap rectMap

Visitor result register: the map from areas to Strings, for clickability.

refPainter

protected SyntaxGraph.RefPainter refPainter

The object used to paint references.

normalStroke

public Painter()

Method Details

paintIt

public SyntaxGraph.RectMap paintIt(Expression expr,
 @Opt
 @Opt SyntaxGraph.RefPainter refPainter,
 Color backgroundColor)

Central Service Access: Paint the complete expression tree. Initial coordinate system is the image to create.
All compound expressions update the affine transform state according to their own SyntaxGraph.y and SyntaxGraph.inX positions, then draw their (more or less complex) line systems and descend into the sub-expressions.
All simple expressions do not change the affine transform state, but use their stored coordinate to paramtrize draw commands. (But they could do it also via the transform state.)

Parameters:

expr - expression which shall be printed

refPainter - used to paint the references. If ==null, a default will be used.

Returns:

the map of areas for to be clickable

action

public void action(Pcdata ref)
