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.

-i, --invert

-l, --layout

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

-s, --scale=[-]<n>

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

-u, --cut=<l,t,w,h>

-v, --verbose

-x, --export=<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.
