_D_e_s_c_r_i_p_t_i_o_n_:

     Copy the current graphics device to a file in a bitmap
     graphics format.

_U_s_a_g_e_:

     dev2bitmap(file, type="png256", height=6, width=6, res=72,
                pointsize, ...)

_A_r_g_u_m_e_n_t_s_:

    file: The putput file name, with an appropriate exten-
          sion.

    type: The type of bitmap. the default is `"png256"'.

  height: The plot height, in inches.

   width: The plot width, in inches.

     res: Resolution, in dots per inch.

pointsize: The pointsize to be used for text: defaults to
          something reasonable given the width and height

     ...: Other parameters passes to `postscript'.

_D_e_t_a_i_l_s_:

     `dev2bitmap' works by copying the current device to a
     `postscript' device, and post-processing the output
     file using `ghostscript'.  You will need a recent ver-
     sion 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', but are likely to include `"pcxmono"',
     `"pcxgray"', `"pcx16"', `"pcx256"', `"pcx24b"', `"pcx-
     cmyk"', `"pbm"', `"pbmraw"', `"pgm"', `"pgmraw"',
     `"pgnm"', `"pgnmraw"', `"pnm"', `"pnmraw"', `"ppm"',
     `"ppmraw"', `"pkm"', `"pkmraw"', `"tiffcrle"',
     `"tiffg3"', `"tiffg32d"', `"tiffg4"', `"tifflzw"',
     `"tiffpack"', `"tiff12nc"', `"tiff24nc"', `"psmono"',
     `"psgray"', `"psrgb"', `"bit"', `"bitrgb"',
     `"bitcmyk"', `"pngmono"', `"pnggray"', `"png16"',
     `"png256"', `"png16m"', `"jpeg"', `"jpeggray"',
     `"pdfwrite"'.

_V_a_l_u_e_:

     None.

_W_A_R_N_I_N_G_:

     This is experimental and may be withdrawn in favour of
     an equivalent device in a later version.

_S_e_e _A_l_s_o_:
