setGraphicContext

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

Sets the GraphicContext

Parameters:

gc - GraphicContext to use

getResolution

private int getResolution()

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(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:

Apply the java paint to the AFP. This takes the java paint sets up the appropriate AFP commands for the drawing with that paint. Currently this supports the gradients and patterns from batik.

Parameters:

paint - the paint to convert to AFP

fill - true if the paint should be set for filling

Returns:

true if the paint is handled natively, false if the paint should be rasterized

Handle the Batik drawing event

Parameters:

shape - the shape to draw
