Method Detail

getInstance

public static TextPainter getInstance()

Returns a unique instance of this class.

paint

public void paint(TextNode node,
                  java.awt.Graphics2D g2d)

Paints the specified text node using the specified Graphics2D.

Parameters:

node - the text node to paint

g2d - the Graphics2D to use

getTextRuns

public java.util.List getTextRuns(TextNode node,
                                  java.text.AttributedCharacterIterator aci)

getOutline

public java.awt.Shape getOutline(TextNode node)

Get a Shape in userspace coords which defines the textnode glyph outlines.

Parameters:

node - the TextNode to measure

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D(TextNode node)

Get a Rectangle2D in userspace coords which encloses the textnode glyphs including stroke etc.

Following copied from interface: org.apache.batik.gvt.TextPainter

Parameters:

node - the TextNode to measure

getMark

public Mark getMark(TextNode node,
                    int index,
                    boolean leadingEdge)

Description copied from interface: TextPainter

Returns a mark for the char at index in node's AttributedCharacterIterator. Leading edge indicates if the mark should be considered immediately 'before' glyph or after

hitTest

protected Mark hitTest(double x,
                       double y,
                       TextNode node)

Description copied from class: BasicTextPainter

Returns the mark for the specified parameters.

Overrides:

hitTest in class BasicTextPainter

selectFirst

public Mark selectFirst(TextNode node)

Selects the first glyph in the text node.

selectLast

public Mark selectLast(TextNode node)

Selects the last glyph in the text node.

getSelected

public int[] getSelected(Mark startMark,
                         Mark finishMark)

Returns an array of ints representing begin/end index pairs into an AttributedCharacterIterator which represents the text selection delineated by two Mark instances. Note: The Mark instances passed must have been instantiated by an instance of this enclosing TextPainter implementation.

getHighlightShape

public java.awt.Shape getHighlightShape(Mark beginMark,
                                        Mark endMark)

Return a Shape, in the coordinate system of the text layout, which encloses the text selection delineated by two Mark instances. Note: The Mark instances passed must have been instantiated by an instance of this enclosing TextPainter implementation.
