Interface TextPainter

public interface TextPainter

Renders the attributed character iterator of a TextNode.
Method Summary
Rectangle2DgetBounds2D(TextNode node)
Get a Rectangle2D in userspace coords which encloses the textnode glyphs rendered bounds (includes stroke etc).
Rectangle2DgetGeometryBounds(TextNode node)
Get a Rectangle2D in userspace coords which encloses the textnode glyphs just including the geometry info.
ShapegetHighlightShape(Mark beginMark, Mark endMark)
Get a Shape in userspace coords which encloses the textnode glyphs bounded by two Marks.
MarkgetMark(TextNode node, int index, boolean beforeGlyph)
Returns a mark for the char at index in node's AttributedCharacterIterator.
ShapegetOutline(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.
voidpaint(TextNode node, Graphics2D g2d)
Paints the specified attributed character iterator using the specified Graphics2D and context and font context.
MarkselectAt(double x, double y, TextNode node)
Initiates a text selection on a particular AttributedCharacterIterator, using the text/font metrics employed by this TextPainter instance.
MarkselectFirst(TextNode node)
Selects the first glyph in the text node.
MarkselectLast(TextNode node)
Selects the last glyph in the text node.
MarkselectTo(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

getBounds2D

public 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 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

getHighlightShape

public 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.

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

getOutline

public Shape getOutline(TextNode node)
Get a Shape in userspace coords which defines the textnode glyph outlines.

Parameters: node the TextNode to measure

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.

paint

public void paint(TextNode node, 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

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.

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.

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.
