Constructor Detail

AFPGraphics2D

public AFPGraphics2D(boolean textAsShapes,
                     AFPPaintingState paintingState,
                     AFPResourceManager resourceManager,
                     AFPResourceInfo resourceInfo,
                     FontInfo fontInfo)

Main constructor

Parameters:

textAsShapes - if true, all text is turned into shapes in the convertion. No text is output.

paintingState - painting state

resourceManager - resource manager

resourceInfo - resource info

fontInfo - font info

AFPGraphics2D

public AFPGraphics2D(AFPGraphics2D g2d)

Copy Constructor

Parameters:

g2d - a AFPGraphics2D whose properties should be copied

Method Detail

getResourceManager

public AFPResourceManager getResourceManager()

Returns the AFP resource manager associated with this Graphics2D instance.

Returns:

the resource manager

getGraphicsObject

public GraphicsObject getGraphicsObject()

Returns the GOCA graphics object

Returns:

the GOCA graphics object

setGraphicsObject

public void setGraphicsObject(GraphicsObject obj)

Sets the GOCA graphics object

Parameters:

obj - the GOCA graphics object

getPaintingState

public AFPPaintingState getPaintingState()

Returns the AFP painting state

Returns:

the AFP painting state

getFontInfo

public FontInfo getFontInfo()

Returns the FontInfo

Returns:

the FontInfo

setGraphicContext

public void setGraphicContext(org.apache.xmlgraphics.java2d.GraphicContext gc)

Sets the GraphicContext

Parameters:

gc - GraphicContext to use

convertToAbsoluteLength

public double convertToAbsoluteLength(double length)

Converts a length value to an absolute value. Please note that this only uses the "ScaleY" factor, so this will result in a bad value should "ScaleX" and "ScaleY" be different.

Parameters:

length - the length

Returns:

the absolute length

applyStroke

protected void applyStroke(java.awt.Stroke stroke)

Apply the stroke to the AFP graphics object. This takes the java stroke and outputs the appropriate settings to the AFP graphics object so that the stroke attributes are handled.

Parameters:

stroke - the java stroke

draw

public void draw(java.awt.Shape shape)

Specified by:

draw in class java.awt.Graphics2D

fill

public void fill(java.awt.Shape shape)

Specified by:

fill in class java.awt.Graphics2D

handleIOException

public void handleIOException(java.io.IOException ioe)

Central handler for IOExceptions for this class.

Parameters:

ioe - IOException to handle

drawString

public void drawString(java.lang.String str,
                       float x,
                       float y)

Specified by:

setCustomTextHandler

public void setCustomTextHandler(org.apache.xmlgraphics.java2d.TextHandler handler)

Sets a custom TextHandler implementation that is responsible for painting text. The default TextHandler paints all text as shapes. A custom implementation can implement text painting using text painting operators.

addNativeImage in interface NativeImageHandler

Parameters:

image - the image to draw

x - the x position

y - the y position

width - the width to draw the image

height - the height to draw the image
