dev2bitmap
works by copying the current device to a
postscript
device, and post-processing the output file
using ghostscript
. You will need a recent version of
ghostscript
(5.10 and later have been tested): the full path to
the executable can be set by the environment variable "R_GSCMD"
.
The types available will depend on the version of ghostscript
,
