GOCR is an OCR (Optical Character Recognition) program, developed under the GNU Public License.

GOCR (or JOCR) is a free optical character recognition program, initially written by Jörg Schulenburg. It can be used to convert or scan image files (portable pixmap or PCX) into text files.

Features.
GOCR claims it can handle single-column sans-serif fonts of 20–60 pixels in height. It reports trouble with serif fonts, overlapping characters, handwritten text, heterogeneous fonts, noisy images, large angles of skew, and text in anything other than a Latin alphabet.

GOCR can also translate barcodes.

User interface.
GOCR can be used as a stand-alone command-line application, or as a back-end to other programs. It comes with a gocr.tcl graphic interface. GOCR can be also used as an OCR engine in OCRFeeder.

Developers releases.

If you want the latest code, get it from this tgz-package. Check this gpg-signature for authenticity of jocr.tgz.

Required software.

Though gocr doesn't need NetPBM, it's benefitted by its presence. libgocr, however, needs it. Get it here. If you already have it installed, take a look if you have the pam.h file. If you don't, it's wise to upgrade.
