PROGRAM:

NAME

xgridfit - a program for gridfitting, or "hinting," TrueType fonts

SYNOPSIS

xgridfit [options] file.{xgf or xml}...

DESCRIPTION

Xgridfit is a simple program that implements an XML-based language for gridfitting, or
"hinting," TrueType fonts. It compiles an XML source file into tables and instructions
that relate to the gridfitting of glyphs. Xgridfit does not insert these elements into a
font itself, but rather relies on FontForge, the Open Source font editor, to do this.

For each input file specified on the command line, the xgridfit command generates a script
named file.py. You may run this script in FontForge thus:

$ fontforge -script file.py

Alternatively, you can skip generation of a script file and execute the script (the
FontForge Python bindings are required for this):

$ xgridfit --execute file.xgf

OPTIONS

Note that many of these options can also be specified by "default" elements in the program
file. However, command-line options always override these defaults.

-a value, --max-stack=value
Size of TrueType stack (default is 256)

-A, --auto-instr
Auto-instruct all glyphs in the font before installing Xgridfit programming. This
option has no effect except in merge-mode (option -m).

-b value, --delta-break=value
Delta Break value: formerly the maximum number of delta pairs that could be placed
on the stack with a single push instruction. As of version 1.11 it approximates
that behavior by setting -p option to twice the specified value. This option has no
effect in Python mode (option -l py).

-c yes|no, --compile-globals=yes|no
Compile functions, control values, pre-program and maxp entries (default is "yes")

-C gray|grey|black|white, --color=gray|grey|black|white
Use this color for rounded distances except where specified otherwise (default is
"gray").

--config=file
Read this configuration file instead of the default.

-d, --debug-mode
Run in debug mode. Output is file.debug rather than file.py

-D, --delete-all
Delete all instruction-related programming and data before installing Xgridfit
programming. This option has no effect except in merge-mode (option -m). Otherwise,
when the output language is Python, TrueType data is deleted except when
--compile-globals=no.

-e Display diagnostic messages (mainly for debugging Xgridfit).

-E, --elapsed-time
Report the time (in seconds) used to run Xgridfit.

-f, --execute
Execute the generated script, and do not save it in a file. This option overrides
-O, and it is incompatible with -d, -S and -z.

-F file, --data-file=file
In merge-mode, Xgridfit stores and reads information about the font's state. By
default, this is stored in FontForge's font.persistent object, which can be stored
only in an .sfd file. Use this option to store font information in a file instead.

-g glyph+list, --glyph-select=glyph+list
Compile only the specified glyphs, ignoring all others. The argument is a list of
one or more glyph names, delimited by plus signs ("+"). The list must contain no
spaces.

-G yes|no, --init-graphics=yes|no
Include or omit at the beginning of each glyph program a function call that
initializes variables used to track the graphics state. The default is "yes." This
option can be overridden with the init-graphics attribute on any glyph element.

-h, --help
Display a help message and exit.

-H yes|no, --auto-hint=yes|no
Auto-hint all glyphs in the font before auto-instructing. This option has no effect
except when auto-instructing is requested (option -A).

-i file, --infile=file
File to be input by generated script. Must have extension .sfd or .ttf

-l py|ff, --language=py|ff
Whether the output of Xgridfit should be a Python script or one in the native
FontForge scripting language. The default is py. Alternatively, set the
environment variable XGRIDFIT_OUTPUT_LANG to "ff" or "py".

-m, --merge-mode
Run in merge-mode. Xgridfit produces a Python script that merges Xgridfit
programming with TrueType programming already present in the font.

-o file, --outfile=file
File to be output by generated script. Must have extension .sfd or .ttf

-O file, --output-script=file
Name of script file to be output by Xgridfit, rather than the default, which
replaces .xgf in the input file with .py

-p value, --push-break=value
The number of values that can be pushed with a single PUSHB or PUSHW instruction.
The default is 255, except when the output language is ff (-l ff); then the default
is 20.

-P yes|no, --combine-prep=yes|no
Combine the Xgridfit pre-program with the prep table already present in the font
(merge-mode only; default is yes).

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

-q, --quiet
Run in quiet mode. Routine messages are suppressed.

-s value, --max-storage=value
Maximum places in TrueType storage area. This area is used to store variables, and
also Xgridfit's own run-time data. The number must always be 24 or greater

-S name, --output-base=name
Save script for each glyph in a separate file named name_glyph-name.py - or .pe or
.debug

--skip-validation
Do not validate the Xgridfit program before compiling.

-t value, --max-twilight=value
Maximum number of points in Twilight zone. The default is 25, but few fonts require
so many

-T file, --temp-file=file
Name of a temporary file in which to store result of XInclude processing: the
compiler and/or validator is run against this file. If this option is used, the
file is not deleted after processing; if it is not used, the file (named by
Xgridfit) is deleted. This option is ignored when a temporary file is not needed.

-v, --version
Print version number and exit

-V Validate the Xgridfit program against a schema before compiling. Compilation is
performed only if validation suceeds. By default xmllint is used for validation;
run xgfconfig to choose another validator.

--validator=libxml2|lxml|jing|msv|rnv
Select a preferred Relax NG validator. Xgridfit will use this validator if
possible.

-x, --skip-compilation
Do not compile. Validation is performed unless suppressed.

-X, --no-xinclude
Assume that XInclude processing is unnecessary; do not check.

-z file, --output-outfile-script=file
When the -S option is present and the -o option or the <outfile> element has been
used to make the output script save a font or FontForge source file, the output of
the <outfile> script is saved in a separate script file. Xgridfit will supply a
default name for this file, but this option lets you supply your own name.
