public abstract class AbstractPSTranscoder extends AbstractFOPTranscoder
This class enables to transcode an input to a PostScript document.
Two transcoding hints (
KEY_WIDTH
andKEY_HEIGHT
) can be used to respectively specify the image width and the image height. If only one of these keys is specified, the transcoder preserves the aspect ratio of the original image.The
KEY_BACKGROUND_COLOR
defines the background color to use for opaque image formats, or the background color that may be used for image formats that support alpha channel.The
KEY_AOI
represents the area of interest to paint in device space.Three additional transcoding hints that act on the SVG processor can be specified:
KEY_LANGUAGE
to set the default language to use (may be used by a <switch> SVG element for example),KEY_USER_STYLESHEET_URI
to fix the URI of a user stylesheet, andKEY_PIXEL_TO_MM
to specify the pixel to millimeter conversion factor.This work was authored by Keiron Liddle (keiron@aftexsw.com).
