Question

I need to user rtessract gem for my ruby on rails project for OCR. I have installed the gem rtesseract using

gem install rtesseract

but when i try to use that gem in my console it throws rtesseract not found error

Can any one have any solution for that. I have also placed the same in gem file and ran bundle but it doesnt work

Answer 1

For RTesseract gem to work you need to install some dependencies like ImageMagick Leptonica and some gems like rmagick. you can install them using

sudo apt-get install imagemagick leptonica

and rmagick gem using

gem install rmagick

or by placing the same in your gem file

You need to have tessdata folder in the

/usr/local/share/tessdata

if you dont have the tessdata you need to download tessdata from tesseract repositry and copy them to the above path
