Ghostscript
Graphics Library
- The
Ghostscript features a high performance graphics
library that provides high-quality graphics for
all the input modules. This unique architecture
minimizes space requirements in embedded products,
reduces maintenance costs and guarantees that
future technology improvements will benefit all
PDLs.
Output
Modules
- Low
level output module (raster): this output
modules tailor the output of the Ghostscript graphics
library (imager) for particular displays, printers
or file formats. In
addition to "chunky" output, the Ghostscript
graphics library also supports planar output.
The low level output module is well-documented
and has been backwardly compatible for over a
decade. Dozens of raster output drivers have been
developed based on this API to provide output
in nearly every raster format imagineable.
-
- High
level output modules (PDFwriter and PSwriter):
these output modules allow users to convert PostScript
or EPS files into PDF files while maintaining
high level vector graphics, font, and text information.
This "distiller" capability produces
smaller files with the ability to edit, search,
and hyperlink. The high level output API is well-documented
and offers the possibility of converting PostScript,
EPS, or PDF datastreams into other high level
formats.
