R Documentation

Report Versions of Graphics Software

Description

Report versions of third-party graphics software available on the current platform for R's graphics.

Usage

grSoftVersion()

Value

A named character vector containing at least the elements

`cairo`	the version of cairographics in use, or `""` if cairographics is not available.
`cairoFT`	the FreeType/FontConfig versions if cairographics is using those libraries directly (not via pango); otherwise, `""`. Earlier versions of R returned `"yes"` rather than the versions. The FontConfig version is determined when R is built.
`pango`	the version of pango in use, or `""` if pango is not available.

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 `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.

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.
