This package provide a custom Heroku buildpack providing the Tesseract OCR binary and all the required libraries to Heroku apps. Training data for English and Finnish language is provided.
The first step consists in allowing your Heroku app to use multiple buildpacks. We use the excellent heroku-buildpack-multi as follows:
add a configuration variable as
heroku config:set BUILDPACK_URL=https://github.com/Carlypso/heroku-buildpack-multi
or (equivalently) change the default buildpack as
heroku buildpacks:set https://github.com/Carlypso/heroku-buildpack-multi
create a file called
.buildpacks inside your app as
LANG is the language used by your app (e.g.,
nodejs). A complete list of Heroku buildpacks can be found here.
tesseractbinary in your Heroku app!
A minimal functioning Heroku app using this buildpack can be found here. The app is coded in Python and provides a REST method that accept an image and return the Tesseract OCR output as a JSON object. The REST functionality is implemented through the Flask web microframework.
This fork solves the issue of the missing libraries
