      public class PSTranscoder
      extends AbstractPSTranscoder

  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.
