ocre(1) FreeBSD General Commands Manual ocre(1)

ocre - ocr e..... (to fill)

ocre [ options] nfImage ...
Options (ephemeral): [-h] [-d ndeb] [-l language] [-p nproc] [-y n] [-C char] [-D ]

ocre recognises characters from the images in the files nfImage ... . The input files must be in pgm(raw) format (256 gray levels), in pbm(raw) format, or in jpg format. At the standard output we get the recognised text.

Some of the present options have been introduced for help in debugging and building a font data base employed to teach the system. There is no commitment for supporting them.
-d ndeb
Writes debugging messages at the standard output.
-h
Writes a help message with options.
-l language
Expects language in the document. Opens a window with specific characters of the language. Adapts the output to the language. (for instance ascii 8859-2 if language is 'pol' (polish)).
-p nproc
Process to do with the images. If nproc is 3, shows the segmented characters. If nproc is 5, writes the characters from the image, each one in a file, under ./arm1 .
-y n
Writes page number: with tags (1), first line (2), only (3).
-C char
writes a enlarged average version of character char.
-D
uses aspell to fill some words.
