This package provides a Cairo graphics device that can be
use to create high-quality vector (PDF, PostScript and SVG)
and bitmap output (PNG,JPEG,TIFF), and high-quality rendering
in displays (X11 and Win32). Since it uses the same back-end
for all output, copying across formats is WYSIWYG.Files are
created without the dependence on X11 or other external programs.
This device supports alpha channel (semi-transparent drawing) and
resulting images can contain transparent and semi-transparent regions.
It is ideal for use in server environemnts (file output) and as a
replacement for other devices that don't have Cairo's capabilities
such as alpha support or anti-aliasing.Backends are modular such that
any subset of backends is supported.
