.SH NAME
ttfautohintGUI \- add new, auto-generated hints to a TrueType font
.SH SYNOPSIS
.B ttfautohintGUI
[\fI\,OPTION\/\fR]...
.SH DESCRIPTION
A GUI application to replace hints in a TrueType font.
.PP
The new hints are based on FreeType's auto\-hinter.
.PP
This program is a simple front\-end to the `ttfautohint' library.
.PP
Long options can be given with one or two dashes,
and with and without equal sign between option and argument.
This means that the following forms are acceptable:
`\-foo=bar', `\-\-foo=bar', `\-foo bar', `\-\-foo bar'.
.PP
Mandatory arguments to long options are mandatory for short options too.
Options not related to Qt or X11 set default values.

.PP
The program accepts both TTF and TTC files as input.
Use option \fB\-i\fR only if you have a legal permission to modify the font.
The used PPEM value for option \fB\-p\fR is FUnits per em, normally 2048.
With option \fB\-s\fR, use default values for standard stem width and height,
otherwise they are derived from script\-specific characters
resembling the shape of character `o'.
.PP
A hint set contains the optimal hinting for a certain PPEM value;
the larger the hint set range (as given by options \fB\-l\fR and \fB\-r\fR),
the more hint sets get computed, usually increasing the output font size.
The `gasp' table of the output file always enables grayscale hinting
for all sizes (limited by option \fB\-G\fR, which is handled in the bytecode).
Increasing the value of \fB\-G\fR does not increase the output font size.
.PP
Options \fB\-f\fR and \fB\-D\fR take a four\-letter string that identifies a script.
Option \fB\-f\fR sets the script used as a fallback for glyphs that can't be
associated with a known script.  By default, such glyphs are hinted;
if option \fB\-S\fR is set, they are scaled only instead.  Option \fB\-D\fR sets the
default script for handling OpenType features.
.PP
Possible four\-letter string values are
.IP
arab (Arabic),
armn (Armenian),
beng (Bengali),
