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

drawArc

void drawArc(int xc,
 int yc,
 int quad,
 boolean isTight)

Draw a quarter of a circle.

Parameters:

xc - x coordinate of center

yc - y coordinate of center

quad - quadrant to paint, in mathematical numbering

isTight - whether to draw with a bold line

drawLine

void drawLine(int x0,
 int y0,
 int x1,
 int y1,
 boolean isTight)

Draw a straight line.

Parameters:

x0 - x coordinate of start

y0 - y coordinate of start

x1 - x coordinate of end

y1 - y coordinate of end

isTight - whether to draw with a bold line

shiftCoordinates

AffineTransform shiftCoordinates(int x,
 int y)

Add a new transformation to the transformation pipeline and return its former state.

action

Paint the graphic representation of pc-data content.

Overrides:

 Expression sub,
 String text)

Paint a dashed box for insertion/substitution/greediness.

Parameters:

exp - the higher expression

sub - the contained expression

text - to print

action

public void action(Insertion ins)

Render an insertion. Either as a dashed box araound an expression, or simply containing the name of a reference.

Overrides:
