\description{
  Copy the current graphics device to a file in a bitmap graphics
  format.
}
\details{
  \code{dev2bitmap} works by copying the current device to a
  \code{\link{postscript}} device, and post-processing the output file
  using \code{ghostscript}.  You will need a recent version of
  \code{ghostscript} (5.10 and later have been tested): the full path to
  the executable can be set by the environment variable \code{"R_GSCMD"}.

  The types available will depend on the version of \code{ghostscript},
  but are likely to include
  \code{"pcxmono"}, \code{"pcxgray"}, \code{"pcx16"}, \code{"pcx256"},
  \code{"pcx24b"}, \code{"pcxcmyk"}, \code{"pbm"}, \code{"pbmraw"},
  \code{"pgm"}, \code{"pgmraw"}, \code{"pgnm"}, \code{"pgnmraw"},
  \code{"pnm"}, \code{"pnmraw"}, \code{"ppm"}, \code{"ppmraw"},
  \code{"pkm"}, \code{"pkmraw"}, \code{"tiffcrle"}, \code{"tiffg3"},
  \code{"tiffg32d"}, \code{"tiffg4"}, \code{"tifflzw"},
  \code{"tiffpack"}, \code{"tiff12nc"}, \code{"tiff24nc"},
  \code{"psmono"}, \code{"psgray"}, \code{"psrgb"}, \code{"bit"},
  \code{"bitrgb"}, \code{"bitcmyk"}, \code{"pngmono"}, \code{"pnggray"},
  \code{"png16"}, \code{"png256"}, \code{"png16m"}, \code{"jpeg"},
  \code{"jpeggray"}, \code{"pdfwrite"}.
