t1mapper [''OPTIONS''? TeX-fontdir Type1-font-file-spec
The t1mapper comes with xdvik. It was made to make it simple to make all sorts of Postscript xdvi. The first invocation is to hi-jack fonts from your Ghostscript installation, which will supply xdvi with all the standard T1 fonts it needs. The second is for hi-jacking any other T1 fonts you may have floating around on your systems.
t1mapper relies on a installed and working texk system to be present. In particular it uses kpsewhich to locate the fontname package .map files which maps between Postscript teTeX is one such texk system.
When invoked without the -gs option t1mapper will examine each of the fonts specified. It will attempt to determine the Postscript name of the font by looking inside the font file, and if that name has a TeX equivalent it will copy, link or symlink your the file into the TeX font directory you named first on the command line. The name in the TeX font directory will be according to the TeX/KB-fontname scheme, so that the font names used in .dvi files matches the names found in the TeX font directories.
All options except -gs have to do with how the font files are copied or linked into the TeX font directories:
Copy the files from the GS-fontdir or matching the Type1-font-file-spec into the TeX-fontdir. This is the default and will always work.
Hard link the files. This requires the fonts to reside on the same disk, but it will save space, and the files will not disappear from the TeX-fontdir if they are removed from the source directory.
Symlink the files. This saves space, but if the original files are removed the symlinks will be broken.
Attempt hard-link first, if it fails make symlink.
If your Ghostscript is installed in /usr/local/share/ghostscript and your TeX lives in /usr/local/teTeX then this command might make your GS fonts available to xdvi:
t1mapper -lns -gs \ /usr/local/share/ghostscript/5.50/Fontmap \ /usr/local/share/ghostscript/fonts \ /usr/local/teTeX/share/texmf/fonts/type1/gs
The first argument here is the full path to the GS Fontmap. The second is the GS font directory, note the lack of wildcards here (as opposed to the next example). The third argument is the TeX font directory. If it does not exist it will be made. Texk and teTeX uses quite finely structured font directories, and the above reflects this.
If have a Solaris machine with Display Postscript fonts then this command might make them available to xdvi:
t1mapper -lns \ /usr/local/teTeX/share/texmf/fonts/type1/gs \ /usr/openwin/lib/X11/fonts/Type1/*.pfa
fontname Postscript to TeX name mapping files from __http://tug.org/fontname/,__ these are included in teTeX.
