PROGRAM:

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.
