Method Detail

setDOMTreeManager

public void setDOMTreeManager(DOMTreeManager domTreeManager)

Sets the DomTreeManager this image handler may need to interact with.

createElement

public org.w3c.dom.Element createElement(SVGGeneratorContext generatorContext)

Creates an Element suitable for referring to images. Note that no assumptions can be made about the name of this Element.

handleImage

public java.awt.geom.AffineTransform handleImage(java.awt.Image image,
                                                 org.w3c.dom.Element imageElement,
