Interface TextPainter

All Known Implementing Classes:

BasicTextPainter

public interface TextPainter

Renders the attributed character iterator of a TextNode.

Method Summary

java.awt.geom.Rectangle2D	getBounds2D(TextNode node) Get a Rectangle2D in userspace coords which encloses the textnode glyphs rendered bounds (includes stroke etc).
java.awt.geom.Rectangle2D	getGeometryBounds(TextNode node) Get a Rectangle2D in userspace coords which encloses the textnode glyphs just including the geometry info.
java.awt.Shape	getHighlightShape(Mark beginMark, Mark endMark) Get a Shape in userspace coords which encloses the textnode glyphs bounded by two Marks.
Mark	getMark(TextNode node, int index, boolean beforeGlyph) Returns a mark for the char at index in node's AttributedCharacterIterator.
java.awt.Shape	getOutline(TextNode node) Get a Shape in userspace coords which defines the textnode glyph outlines.
int[]	getSelected(Mark start, Mark finish) Get an array of index pairs corresponding to the indices within an AttributedCharacterIterator regions bounded by two Marks.
void	paint(TextNode node, java.awt.Graphics2D g2d) Paints the specified attributed character iterator using the specified Graphics2D and context and font context.
Mark	selectAt(double x, double y, TextNode node) Initiates a text selection on a particular AttributedCharacterIterator, using the text/font metrics employed by this TextPainter instance.
Mark	selectFirst(TextNode node) Selects the first glyph in the text node.
Mark	selectLast(TextNode node) Selects the last glyph in the text node.
Mark	selectTo(double x, double y, Mark beginMark) Continues a text selection on a particular AttributedCharacterIterator, using the text/font metrics employed by this TextPainter instance.

Method Detail

paint

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

Paints the specified attributed character iterator using the specified Graphics2D and context and font context.

Parameters:

node - the TextNode to paint

g2d - the Graphics2D to use

context - the rendering context.

selectAt

public Mark selectAt(double x,
                     double y,
                     TextNode node)

Initiates a text selection on a particular AttributedCharacterIterator, using the text/font metrics employed by this TextPainter instance.

selectTo

public Mark selectTo(double x,
                     double y,
                     Mark beginMark)

Continues a text selection on a particular AttributedCharacterIterator, using the text/font metrics employed by this TextPainter instance.

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.

getMark

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

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

getSelected

public int[] getSelected(Mark start,
                         Mark finish)

Get an array of index pairs corresponding to the indices within an AttributedCharacterIterator regions bounded by two Marks. Note that the instances of Mark passed to this function must come from the same TextPainter that generated them via selectAt() and selectTo(), since the TextPainter implementation may rely on hidden implementation details of its own Mark implementation.

getHighlightShape

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

Get a Shape in userspace coords which encloses the textnode glyphs bounded by two Marks. Note that the instances of Mark passed to this function must come from the same TextPainter that generated them via selectAt() and selectTo(), since the TextPainter implementation may rely on hidden implementation details of its own Mark implementation.

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 rendered bounds (includes stroke etc).

Parameters:

node - the TextNode to measure

getGeometryBounds

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

Get a Rectangle2D in userspace coords which encloses the textnode glyphs just including the geometry info.

Parameters:

node - the TextNode to measure
