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.
