.SH "NAME"
mftraining \- feature training for Tesseract
.SH "SYNOPSIS"
.sp
mftraining \-U \fIunicharset\fR \-O \fIlang\&.unicharset\fR \fIFILE\fR\&...
.SH "DESCRIPTION"
.sp
mftraining takes a list of \&.tr files, from which it generates the files \fBinttemp\fR (the shape prototypes), \fBshapetable\fR, and \fBpffmtable\fR (the number of expected features for each character)\&. (A fourth file called Microfeat is also written by this program, but it is not used\&.)
.SH "OPTIONS"
.PP
\-U \fIFILE\fR
.RS 4
(Input) The unicharset generated by unicharset_extractor(1)
.RE
.PP
\-F \fIfont_properties_file\fR
.RS 4
(Input) font properties file, each line is of the following form, where each field other than the font name is 0 or 1:
.sp
.if n \{\
.RS 4
.\}
.nf
*font_name* *italic* *bold* *fixed_pitch* *serif* *fraktur*
.fi
.if n \{\
.RE
.\}
.RE
.PP
\-X \fIxheights_file\fR
.RS 4
(Input) x heights file, each line is of the following form, where xheight is calculated as the pixel x height of a character drawn at 32pt on 300 dpi\&. [ That is, if base x height + ascenders + descenders = 133, how much is x height? ]
.sp
.if n \{\
.RS 4
.\}
.nf
*font_name* *xheight*
.fi
.if n \{\
.RE
.\}
.RE
.PP
\-D \fIdir\fR
.RS 4
Directory to write output files to\&.
.RE
.PP
\-O \fIFILE\fR
.RS 4
(Output) The output unicharset that will be given to combine_tessdata(1)
.RE
