Class AbstractFOPTextPainter

java.lang.Object
  org.apache.fop.svg.AbstractFOPTextPainter

All Implemented Interfaces:

org.apache.batik.bridge.TextPainter

Direct Known Subclasses:

AFPTextPainter

public abstract class AbstractFOPTextPainter
extends java.lang.Object
implements org.apache.batik.bridge.TextPainter

Renders the attributed character iterator of a TextNode. This class draws the text directly into the Graphics2D so that the text is not drawn using shapes. 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.

Constructor Detail

AbstractFOPTextPainter

public AbstractFOPTextPainter(FOPTextHandler nativeTextHandler,
                              org.apache.batik.bridge.TextPainter proxyTextPainter)

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

Parameters:

nativeTextHandler - the NativeTextHandler instance used for text painting

Method Detail

paint

public void paint(org.apache.batik.bridge.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.bridge.TextPainter

Parameters:

node - the TextNode to paint

g2d - the Graphics2D to use

isSupportedGraphics2D

protected abstract boolean isSupportedGraphics2D(java.awt.Graphics2D g2d)

Checks whether the Graphics2D is compatible with this text painter. Batik may pass in a Graphics2D instance that paints on a special buffer image, for example for filtering operations. In that case, the text painter should be bypassed.

Parameters:

g2d - the Graphics2D instance to check

Returns:

true if the Graphics2D is supported

getText

protected java.lang.String getText(java.text.AttributedCharacterIterator aci)

Extract the raw text from an ACI.

Parameters:

aci - ACI to inspect

Returns:

the extracted text

getOutline

public java.awt.Shape getOutline(org.apache.batik.bridge.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.bridge.TextPainter

Parameters:

node - the text node

Returns:

the outline shape of the text characters

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D(org.apache.batik.bridge.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.bridge.TextPainter

Parameters:

node - the text node

Returns:

the bounds of the text

getGeometryBounds

public java.awt.geom.Rectangle2D getGeometryBounds(org.apache.batik.bridge.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.bridge.TextPainter

Parameters:

node - the text node

Returns:

the bounds of the text

getMark

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

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

Specified by:

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

Parameters:

node - the text node

pos - the position

all - select all

Returns:

null

selectAt

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

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

Specified by:

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