NAME

ttf2ufm_convert - convenience font conversion script

SYNOPSIS

ttf2ufm_convert [config-file]

DESCRIPTION

`Convert' is the master conversion script provided with ttf2ufm. When installed into a
public directory it's named `ttf2ufm_convert' to avoid name collisions with the other
programs.

If the configuration file is not specified as an argument then the file `"convert.cfg"' in
the current directory is used. This file contains a set of configuration variables. The
distribution contains a sample file file `"convert.cfg.sample"'. Please copy it to
`"convert.cfg"', look inside it and change the configuration variables. The more stable
configuration variables, such as the path names of the scripts and encoding files are
located in `"convert"' itself, they are automatically updated when installing ttf2ufm.

Put all the TTF fonts you want to convert into some directory (this may be just the
directory that already contains all the Windows fonts on a mounted FAT filesystem). If you
have fonts in different source encoding then put the fonts in each of the encodings into a
separate directory. Up to 10 source directories are supported. If you (in a rather
unlikely case) have more source directories then you can make two separate runs of the
converter, converting up to 10 directories at a time.

The variables in the configuration file are:

· "SRCDIRS" - the list of directories (with absolute paths) with TTF fonts. Each line
contains at least 3 fields: the name of the directory, the language of the fonts in it
(if you have fonts for different languages you have to put them into the separate
directories) and the encoding of the fonts. Again, if you have some of the TTF typefaces
in one encoding, and some in another (say, CP-1251 and KOI-8), you have to put them into
the separate source directories. Some lines may contain 4 fields. Then the fourth field
is the name of the external map to convert the Unicode fonts into the desirable
encoding. This map is used instead of the built-in map for the specified language.

*8* An interesting thing is that some languages have more than one widely used character
encodings. For example, the widely used encodings for Russian are IBM CP-866 (MS-DOS and
Unix), KOI-8 (Unix and VAX, also the standard Internet encoding), IBM CP-1251 (MS
Windows). That's why I have provided the means to generate the converted fonts in more
than one encoding. See the file encodings/README for details about the encoding tables.
Actually, if you plan to use these fonts with Netscape Navigator better use the aliases
cp-866 instead of ibm-866 and windows-1251 instead of ibm-1251 because that's what
Netscape wants.

· "DSTDIR" - directory for the resulting Type1 fonts. Be careful! This directory gets
completely wiped out before conversion, so don't use any already existing directory for
this purpose.

· "DSTENC{language}" - the list of encodings in which the destination fonts will be
generated for each language. Each font of that language will be generated in each of the
specified encodings. If you don't want any translation, just specify both "SRCENC" and
"DSTENC" as iso8859-1 (or if you want any other encoding specified in the fonts.dir,
copy the description of 8859-1 with new name and use this new name for "SRCENC" and
"DSTENC").

· "FOUNDRY" - the foundry name to be used in the fonts.dir file. I have set it to
`fromttf' to avoid name conflicts with any existing font for sure. But this foundry name
is not registered in X11 standards and if you want to get the full standard compliance
or have a font server that enforces such a compliance, use `misc'.

The next few parameters control the general behavior of the converter. They default
values are set to something reasonable.

· "CORRECTWIDTH" - if the value is set to "YES" then use the converter option "-w",
otherwise don't use it. See the description of this option in the README file.

· "REMOVET1A" - if the value is set to "YES" then after conversion remove the un-encoded
".t1a" font files and the intermediate ".xpfa" font metric files.

· "INSTALLFONTMAP" - a Ghostscript parameter, if the value is set to "YES" then install
the entries for the new fonts right into the main "Fontmap" file. Otherwise just leave
the file "Fontmap.ttf" in the Ghostscript configuration directory.

· "HINTSUBST" - if the value is set to "YES" use the option "-H", otherwise don't use it.
This option enables the hint substitution technique. If you have not installed the X11
patch described above, use this option with great caution. See further description of
this option in the README file.

· "ENFORCEISO" - if the value is set to "YES" then disguise the resulting fonts as the
fonts in ISOLatin1 encoding. Historically this was neccessary due to the way the
installer scripts created the X11 font configuration files. It is not neccessary any
more for this purpose. But if you plan to use these fonts with some other application
that expects ISOLatin1 encoding then better enable this option.

· "ALLGLYPHS" - if the value is set to "YES" then include all the glyphs from the source
fonts into the resulting fonts, even if these glyphs are inaccessible. If it's set to
"NO" then include only the glyphs which have codes assigned to them. The glyphs without
codes can not be used directly. But some clever programs, such as the Type 1 library
from XFree86 3.9 and higher can change the encoding on the fly and use another set of
glyphs. If you have not installed the X11 patch described above, use this option with
great caution. See further description of the option option "-a" in the README file.

· "GENUID" - if the value is set to "YES" then use the option "-uA" of the converter to
generate UniqueIDs for the converted fonts. The standard X11 Type 1 library does not use
this ID, so it may only be neccessary for the other applications. The script is clever
enough to generate different UniqueID for the same font converted to multiple encodings.
Also after conversion it checks all the fonts generacted during the session for
duplicated UniqueID and shows those. Still, this does not quarantee that these UniqueIDs
won't overlap with some other fonts. The UniqueIDs are generated as hash values from the
font names, so it's guaranteed that if the `"convert"' script runs multiple times it
will generate the same UniqueIDs during each run. See further description of this option
in the README file.

· "GENUID" - if the value is set to "YES" then create the ".pfb" files, otherwise the
".pfa" files. The ".pfb" files are more compact but contain binary data, so you may
experience some troubles when transferring them through the network.

The following parameters are used to locate the other scripts and configuration files. By
default the scripts do a bit of guessing for them: they search in the ttf2ufm installation
directory if ttf2ufm was installed or otherwise suppose that you are running `"convert"'
with `"scripts"' subdirectory being the current directory.

· "ENCDIR" - directory containing the descriptions of encodings

· "MAPDIR" - directory containing the external map files

Besides that a few parameters are built into the `"convert"' script itself. You probably
won't need to change them:

· "T1ASM", "TTF2UFM", "TRANS", "T1FDIR", "FORCEISO" - paths to the other script

Also there are a few parameters controlling the installation of fonts for Ghostscript.
Please look at their description in the Ghostscript section of documentation or in the
ttf2ufm_x2gs(1) manual page before running `"convert"'. If these parameters are set,
`"convert"' will call the `"x2gs"' script automatically to install the newly converted
fonts in Ghostscript.

After creating the configuration file run the `"convert"' script. Look at the result and
the log file in "DSTDIR".

Add the directory with newly converted fonts to the configuration of X server or font
server. For most of the systems this step is very straightforward. For HP-UX it's rather
tricky and poorly documented, so the file FONTS.hpux gives a short description.

If you don't have the privileges of the root user, you still can configure your private
font server. Just use some non-standard port number (see FONTS.hpux for an example, exept
that you won't need all the HP-related stuff on any other system).
