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. If no files are specified, ocrad reads the image from standard input. If the -o option is not specified, ocrad sends text to stan- dard output. Ocrad includes a layout analyser able to separate the columns or blocks of text normally found on printed pages. OPTIONS
