  org.apache.fop.svg.PDFTextPainter

All Implemented Interfaces:

org.apache.batik.gvt.TextPainter

public class PDFTextPainter

extends java.lang.Object

implements org.apache.batik.gvt.TextPainter

Renders the attributed character iterator of a TextNode. This class draws the text directly into the PDFGraphics2D so that the text is not drawn using shapes which makes the PDF files larger. If the text is simple enough to draw then it sets the font and calls drawString. If the text is complex or the cannot be translated into a simple drawString the StrokingTextPainter is used instead. (todo) handle underline, overline and strikethrough (todo) use drawString(AttributedCharacterIterator iterator...) for some

Field Detail

PROXY_PAINTER

protected static final org.apache.batik.gvt.TextPainter PROXY_PAINTER

Use the stroking text painter to get the bounds and shape. Also used as a fallback to draw the string with strokes.

Constructor Detail

PDFTextPainter

public PDFTextPainter(FontInfo fi)

Create a new PDF text painter with the given font information.

Parameters:

fi - the fint info

Method Detail

paint

public void paint(org.apache.batik.gvt.TextNode node,
                  java.awt.Graphics2D g2d)

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

Specified by:

paint in interface org.apache.batik.gvt.TextPainter

Parameters:

node - the TextNode to paint

g2d - the Graphics2D to use

getOutline

public java.awt.Shape getOutline(org.apache.batik.gvt.TextNode node)

Get the outline shape of the text characters. This uses the StrokingTextPainter to get the outline shape since in theory it should be the same.

Specified by:

getOutline in interface org.apache.batik.gvt.TextPainter

Parameters:

node - the text node

Returns:

the outline shape of the text characters

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D(org.apache.batik.gvt.TextNode node)

Get the bounds. This uses the StrokingTextPainter to get the bounds since in theory it should be the same.

Specified by:

getBounds2D in interface org.apache.batik.gvt.TextPainter

Parameters:

node - the text node

Returns:

the bounds of the text

getGeometryBounds

public java.awt.geom.Rectangle2D getGeometryBounds(org.apache.batik.gvt.TextNode node)

Get the geometry bounds. This uses the StrokingTextPainter to get the bounds since in theory it should be the same.

Specified by:

getGeometryBounds in interface org.apache.batik.gvt.TextPainter

Parameters:

node - the text node

Returns:

the bounds of the text

getMark

public org.apache.batik.gvt.text.Mark getMark(org.apache.batik.gvt.TextNode node,
                                              int pos,
                                              boolean all)

Get the mark. This does nothing since the output is pdf and not interactive.

Specified by:

getMark in interface org.apache.batik.gvt.TextPainter

Parameters:

node - the text node

pos - the position

all - select all

Returns:

null

selectAt

public org.apache.batik.gvt.text.Mark selectAt(double x,
                                               double y,
                                               org.apache.batik.gvt.TextNode node)

Select at. This does nothing since the output is pdf and not interactive.

Specified by:

selectAt in interface org.apache.batik.gvt.TextPainter

Parameters:

x - the x position

y - the y position

node - the text node

Returns:

null

selectTo

public org.apache.batik.gvt.text.Mark selectTo(double x,
