1.1       maekawa     1: METAFONT Terminal Driver for gnuplot (mf.trm):
                      2: ----------------------------------------------
                      3:
                      4: The METAFONT terminal driver creates a input file to the METAFONT program.
                      5: Thus a figure may be used in the TeX document in the same way as a
                      6: character is.
                      7:
                      8: To use the plot in a document the METAFONT program must be run
                      9: with the output file from gnuplot as input. Thus, the user needs a basic
                     10: knowledge of the font creating prosess and inclusion of a new font in a
                     11: document. However, if the METAFONT program are set up properly at the
                     12: local site an unexperienced user could perform the operation without
                     13: much trouble.
                     14:
                     15: The text support is based on a METAFONT character set.
                     16: Currently the Computer Modern Roman font set is input but the
                     17: user are in principal free to chose whatever fonts he/she needs.
                     18: The METAFONT source files for the chosen font must be available.
                     19: Each character is stored in a separate picture variable in METAFONT. These
                     20: variables may be manipulated (rotated, scaled etc.) when characters are
                     21: needed. The drawback is the interpretation time in the METAFONT
                     22: program. On some machines (i.e. PC) the limited amount of memory available
                     23: may also cause problem if too many pictures are stored.
                     24:
                     25: To use the METAFONT terminal driver:
                     26: ------------------------------------
                     27: 1) In gnuplot use:   set terminal mf
                     28:                      set output "myfile.mf"
                     29:                           .
                     30:                           .
                     31:                           .
                     32:                      plot ....
                     33:                      exit
                     34:
                     35:
                     36: 2) Run METAFONT. Syntax is site dependant:
                     37:
                     38:    On my UNIX I use:   cmmf '\mode=localfont; \mag=1;' input myfile.mf
                     39:    On my PC I use:     mf286 &cm \mode=localfont; \mag=1; input myfile.mf
                     40:
                     41:    Be aware that METAFONT can only handle number less than 4096. Thus if you
                     42:
                     43:    have very high resolution in your localfont and a large picture you will
                     44:    probably get an error message when running METAFONT. To solve the
                     45: problem,
                     46:    reduce the resolution or the plot size.
                     47:
                     48: 3) Run GfToPk, syntax is
                     49:
                     50:    on my UNIX:   gftpk myfile.xxxgf myfile.pk
                     51:    on my PC:     gftpk myfile.xxx myfile.pk
                     52:
                     53:    where xxx is the resolution (typically 300).
                     54:
                     55: 4) Copy the files myfile.pk and myfile.tfm to a place where you are sure TeX
                     56:    and the dvi processing programs you use  can find them. (They can
                     57: probably
                     58:    be located in your current working directory)
                     59:
                     60: 5) Include in your TeX document the following statement:
                     61:
                     62:       \font\myfont=myfile  % Declares the new font you just have made
                     63:       {\myfont\char0}      % Typeset character with code zero which
                     64:                            % MF.TRM uses as default character
