NAME
mftraining - feature training for Tesseract
SYNOPSIS
mftraining -U unicharset -O lang.unicharset FILE...
DESCRIPTION
mftraining takes a list of .tr files, from which it generates the files
inttemp (the shape prototypes), shapetable, and pffmtable (the number
of expected features for each character). (A fourth file called
Microfeat is also written by this program, but it is not used.)
OPTIONS
-U FILE
(Input) The unicharset generated by unicharset_extractor(1)
-F font_properties_file
(Input) font properties file, each line is of the following form,
where each field other than the font name is 0 or 1:
*font_name* *italic* *bold* *fixed_pitch* *serif* *fraktur*
-X xheights_file
(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? ]
*font_name* *xheight*
-D dir
Directory to write output files to.
-O FILE
(Output) The output unicharset that will be given to
combine_tessdata(1)
