This package provide a custom Heroku buildpack providing the Tesseract OCR binary and all the required libraries to Heroku apps. Training data for English, Dutch 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/ddollar/heroku-buildpack-multi
or (equivalently) change the default buildpack as
heroku buildpacks:set https://github.com/ddollar/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.
Copy the snippet above into CLI.
