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)
