GOCR is an optical character recognition program, released under the GNU General Public License. It reads images in many formats (pnm, pbm, pgm, ppm, some pcx and tga image files (or PNM from stdin); if PNM-tools installed and running linux-like system you can also use pnm.gz, pnm.bz2, png, jpg, tiff, gif, bmp and others) and outputs a text file. You do not have to train the program or store large font bases. Simply call gocr from the command line and get your results.
