OCR in ruby

[wyrosdick]

does anyone know of an OCR library in ruby or one that can be called
from command line so I can integrate it with a ruby script?

I don't know of a specific ruby library to do this. However, there is a GNU OCR
project - you could probably bind to its library and use that? It also has a
command line utility that can take input from stdin and send text output to
stdout - possibly you could try using that to see if the genral principal
works.

P.S. from memory its called gocr

that worked beautifully ... I use imagemagick to convert the image to
a pgm file then use `gocr -i file.pgm` to get the ocr text from the
command line tool inside of ruby.
