NAME
     ttx -- tool for manipulating TrueType and OpenType	fonts

SYNOPSIS
     ttx [option ...] file ...

DESCRIPTION
     ttx is a tool for manipulating TrueType and OpenType fonts.  It can con-
     vert TrueType and OpenType	fonts to and from an XML-based format called
     TTX.  TTX files have a `.ttx' extension.

     For each file argument it is given, ttx detects whether it	is a `.ttf',
     `.otf' or `.ttx' file and acts accordingly: if it is a `.ttf' or `.otf'
     file, it generates	a `.ttx' file; if it is	a `.ttx' file, it generates a
     `.ttf' or `.otf' file.

     By	default, every output file is created in the same directory as the
     corresponding input file and with the same	name except for	the extension,
     which is substituted appropriately.  ttx never overwrites existing	files;
     if	necessary, it appends a	suffix to the output file name before the ex-
     tension, as in Arial#1.ttf.

   General options
     -h	       Display usage information.

     -d	dir    Write the output	files to directory dir instead of writing ev-
	       ery output file to the same directory as	the corresponding in-
	       put file.

     -o	file   Write the output	to file	instead	of writing it to the same di-
	       rectory as the corresponding input file.

     -v	       Be verbose.  Write more messages	to the standard	output de-
	       scribing	what is	being done.

     -a	       Allow virtual glyphs ID's on compile or decompile.

   Dump	options
     The following options control the process of dumping font files (TrueType
     or	OpenType) to TTX files.

     -l	       List table information.	Instead	of dumping the font to a TTX
	       file, display minimal information about each table.

     -t	table  Dump table table.  This option may be given multiple times to
	       dump several tables at once.  When not specified, all tables
	       are dumped.

     -x	table  Exclude table table from	the list of tables to dump.  This op-
	       tion may	be given multiple times	to exclude several tables from
	       the dump.  The -t and -x	options	are mutually exclusive.

     -s	       Split tables.  Dump each	table to a separate TTX	file and write
	       (under the name that would have been used for the output	file
	       if the -s option	had not	been given) one	small TTX file con-
	       taining references to the individual table dump files.  This
	       file can	be used	as input to ttx	as long	as the referenced
	       files can be found in the same directory.

     -i	       Don't disassemble TrueType instructions.	 When this option is
	       specified, all TrueType programs	(glyph programs, the font pro-
	       gram and	the pre-program) are written to	the TTX	file as	hexa-
	       decimal data instead of assembly.  This saves some time and re-
	       sults in	smaller	TTX files.

     -y	n      When decompiling	a TrueType Collection (TTC) file, decompile
	       font number n, starting from 0.

   Compilation options
     The following options control the process of compiling TTX	files into
     font files	(TrueType or OpenType):

     -m	fontfile
	       Merge the input TTX file	file with fontfile.  No	more than one
	       file argument can be specified when this	option is used.

     -b	       Don't recalculate glyph bounding	boxes.	Use the	values in the
	       TTX file	as is.

THE TTX	FILE FORMAT
     You can find some information about the TTX file format in
     documentation.html.  In particular, you will find in that file the	list
     of	tables understood by ttx and the relations between TrueType GlyphIDs
     and the glyph names used in TTX files.

EXAMPLES
     In	the following examples,	all files are read from	and written to the
     current directory.	 Additionally, the name	given for the output file as-
     sumes in every case that it did not exist before ttx was invoked.

     Dump the TrueType font contained in FreeSans.ttf to FreeSans.ttx:

	   ttx FreeSans.ttf

     Compile MyFont.ttx	into a TrueType	or OpenType font file:

	   ttx MyFont.ttx

     List the tables in	FreeSans.ttf along with	some information:

	   ttx -l FreeSans.ttf

     Dump the `cmap' table from	FreeSans.ttf to	FreeSans.ttx:

	   ttx -t cmap FreeSans.ttf

NOTES
     On	MS-Windows and MacOS, ttx is available as a graphical application to
     which files can be	dropped.
