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)
