ttx2xgf

TTX2XGF(1)						      General Commands Manual							TTX2XGF(1)

NAME

       ttx2xgf - extracts instructions from a TTX file and creates an Xgridfit program.

SYNOPSIS

       ttx2xgf [options] infile[.ttx] [outfile]

DESCRIPTION

       ttx2xgf	is a utility that extracts instructions (hints) and other information relating to instructions from a TTX file (an XML representa-
       tion of a TrueType font) and creates a new Xgridfit program.

       If infile lacks the .ttx extension, it is assumed. If outfile is not given, output is written to infile.xgf.

OPTIONS

       --config
	      Path to a configuration file (relative paths are permitted).  If this is not given, ttx2xgf will look first for a file config.xml in
	      the current directory, next in the user's Xgridfit configuration directory, and finally in the Xgridfit base directory.

       -e     Display diagnostic messages (for debugging).

       -E, --elapsed-time
	      Time the running of this program and display the result.

       --processor=libxslt|lxml|xsltproc|saxon-6|saxon-9|xalan-j|xalan-c|4xslt
	      Select a preferred XSLT processsor; ttx2xgf will use this one if possible.

FILES

       /usr/share/xml/xgridfit/util/convert-ttx.xsl
	      An XSLT script that performs the initial conversion.

       /usr/share/xml/xgridfit/util/convert-asm.sed
	      A Sed script that completes the conversion.

SEE ALSO

       xgridfit(1), xgfconfig(1), ttx(1)
