## org.apache.fop.svg
Class AbstractFOPTextPainter

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

All Implemented Interfaces:
  org.apache.batik.gvt.TextPainter

Direct Known Subclasses:
  AFPTextPainter

public abstract class AbstractFOPTextPainter
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 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.

Field Summary

`protected static org.apache.batik.gvt.TextPainter` | `PROXY_PAINTER` Use the stroking text painter to get the bounds and shape.

Field Detail

### log

    protected org.apache.commons.logging.Log log

  the logger for this class

### 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

### AbstractFOPTextPainter

    public AbstractFOPTextPainter(FOPTextHandler nativeTextHandler)

  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.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

### 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

### paintTextRuns

    protected void paintTextRuns(java.util.List textRuns,

                                 java.awt.geom.Point2D loc)

  Paint a list of text runs on the Graphics2D at a given location.

  Parameters:
    `textRuns` - the list of text runs
    `g2d` - the Graphics2D to paint to
    `loc` - the current location of the "cursor"

### paintTextRun

    protected java.awt.geom.Point2D paintTextRun(org.apache.batik.gvt.renderer.StrokingTextPainter.TextRun run,

                                                 java.awt.geom.Point2D loc)

  Paint a single text run on the Graphics2D at a given location.

  Parameters:
