r-cran-cairo - 1.6-2-1+b1 main

GNUR R graphics device using cairo graphics library for creating high-
quality bitmap (PNG, JPEG, TIFF), vector (PDF, SVG, PostScript) and
display (X11 and Win32) output
.
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 environments (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.
