grSoftVersion()
A named character vector containing at least the elements
cairo |
the version of cairographics in use, or |
It may also contain the versions of third-party software used by the standard (on Windows), or X11-based (on Unix-alikes) bitmap devices:
libpng |
the version of |
jpeg |
the version of the JPEG headers used for compilation,
or |
libtiff |
the version of |
It is conceivable but unlikely that the cairo-based bitmap devices
will use different versions linked via cairographics,
especially png(type = "cairo-png").
On macOS, if available, the Quartz-based devices will use the system versions of these libraries rather than those reported here.
Unless otherwise stated the reported version is that of the (possibly dynamically-linked) library in use at runtime.
Note that libjpeg-turbo as used on some Linux distributions
reports its version as "6.2", the IJG version from which it forked.
extSoftVersion for versions of non-graphics software.
