 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, 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.

Method Detail

paint

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

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

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

Mark selectFirst(TextNode node)
Selects the first glyph in the text node.


selectLast

Mark selectLast(TextNode node)
Selects the last glyph in the text node.


getMark

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

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

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

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

Parameters:
node - the TextNode to measure

getBounds2D

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

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
