public abstract class AbstractPSTranscoder extends AbstractFOPTranscoder
This class enables to transcode an input to a PostScript document.
Two transcoding hints (KEY_WIDTH
and
KEY_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, and KEY_PIXEL_TO_MM
to specify the pixel to
millimeter conversion factor.
