Report Versions of Graphics Software

Report versions of third-party graphics software.

Usage
grSoftVersion()
Value

A named character vector containing at least the element

cairo

the version of cairographics in use, or "" if cairographics is not available.

It may also contain the versions of third-party software used by the standard X11-based (not cairo-based) bitmap devices:

libpng

the version of libpng in use, or "" if not available.

jpeg

the version of the JPEG headers used for compilation, or "" if JPEG support was not compiled in.

libtiff

the version of libtiff in use, or "" if not available.

Unless otherwise stated the reported version is that of the (possibly dynamically-linked) library in use at runtime.

Note that libjpeg-turbo used on some Linux distributions reports its version as "6.2", the IJG version from which it forked.

See Also
