org.apache.batik.transcoder.AbstractTranscoder
org.apache.batik.transcoder.XMLAbstractTranscoder
org.apache.fop.svg.PDFTranscoder
This class enables to transcode an input to a pdf 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_UNIT_TO_MILLIMETER to specify the pixel to millimeter conversion factor.
