PrintTranscoder
public class PrintTranscoder extends SVGAbstractTranscoder implements Printable(Code)
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:
  • KEY_LANGUAGE, KEY_USER_STYLESHEET_URI, KEY_PIXEL_TO_MM, KEY_XML_PARSER_CLASSNAME can be used to set the defaults for the various SVG properties.
  • KEY_PAGE_WIDTH, KEY_PAGE_HEIGHT, KEY_MARGIN_TOP, KEY_MARGIN_BOTTOM, KEY_MARGIN_LEFT, KEY_MARGIN_RIGHT and KEY_PAGE_ORIENTATION can be used to specify the printing page characteristics.
  • KEY_WIDTH, KEY_HEIGHT can be used to specify how to scale the SVG image
  • KEY_SCALE_TO_PAGE can be used to specify whether or not the SVG image should be scaled uniformly to fit into the printed page or if it should just be centered into the printed page.
