Class PrintTranscoder

All Implemented Interfaces:
Printable, Transcoder
public class PrintTranscoder
extends SVGAbstractTranscoder
implements Printable

This class is a Transcoder that prints SVG images. This class works as follows: any-time the transcode method is invoked, the corresponding input is cached and nothing else happens.
However, the PrintTranscoder is also a Printable. If used in a print operation, it will print each of the input it cached, one input per page.
The PrintTranscoder uses several different hints that guide its printing:
