Heroku Buildpack Tesseract

This package provide a custom Heroku buildpack providing the Tesseract OCR binary and all the required libraries to Heroku apps. Training data for English language is provided.


The first step consists in allowing your Heroku app to use multiple buildpacks. Heroku natively supports multiple buildpacks per app.

  1. setup your app as

    heroku buildpacks:set heroku/LANG
    heroku buildpacks:add https://github.com/oswellchan/heroku-buildpack-tesseract

    where LANG is the language used by your app (e.g., ruby, python, or nodejs). A complete list of Heroku buildpacks can be found here.

  2. you can use the tesseract binary in your Heroku app!

  3. deploy :)


This fork upgrades Tesseract binary version from 3.03 to 3.04.01
