NAME

       ocrad - command line text recognition tool

SYNOPSIS

       ocrad [options] [files]

DESCRIPTION

       GNU  Ocrad  is  an  OCR  (Optical Character Recognition) program based on a feature extraction method. It
       reads images in pbm (bitmap), pgm (greyscale) or ppm (color) formats and produces text in byte (8-bit) or
       UTF-8 formats. The pbm, pgm and ppm formats are collectively known as pnm.

       Ocrad includes a layout analyser able to separate the columns or blocks of text normally found on printed
       pages.

OPTIONS

       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -a, --append
              append text to output file

       -c, --charset=<name>
              try '--charset=help' for a list of names

       -e, --filter=<name>
              try '--filter=help' for a list of names

       -f, --force
              force overwrite of output file

       -F, --format=<fmt>
              output format (byte, utf8)

       -i, --invert
              invert image levels (white on black)

       -l, --layout
              perform layout analysis

       -o, --output=<file>
              place the output into <file>

       -q, --quiet
              suppress all messages

       -s, --scale=[-]<n>
              scale input image by [1/]<n>

       -t, --transform=<name>
              try '--transform=help' for a list of names

       -T, --threshold=<n%>
              threshold for binarization (0-100%)

       -u, --cut=<l,t,w,h>
              cut input image by given rectangle

       -v, --verbose
              be verbose

       -x, --export=<file>
              export results in ORF format to <file>

       If no files are specified, ocrad reads the image from standard input.  If the -o option is not specified,
       ocrad sends text to standard output.

       Exit  status:  0  for  a  normal  exit,  1 for environmental problems (file not found, invalid flags, I/O
       errors, etc), 2 to indicate a corrupt or invalid input file, 3 for an  internal  consistency  error  (eg,
       bug) which caused ocrad to panic.
