Tesseract OCR Plugin for Cordova

How to install

Before installing the plugin to your project, you need to do a few things:

  1. Copy the contents of the libs folder to platforms/android/libs directory of your Cordova project
  2. Copy the tessdata folder to platforms/android/assets directory of your Cordova project
  3. Instal the plugin using cordova plugin add http://github.com/phoenixtwister/cordova-juleskelly-tesseract.git

How to use

Add this code on the deviceready event of your project. This takes time on your first run of your application.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    tesseractOCR.load(function (callback) {
      // your code here
    }
}

Whenever you want to scan the text on your image, you have to pass the image path to the recognizeImage method.

tesseractOCR.recognizeImage(imageURL, function (result) {
  // the result argument stores the recognized text
  
});

Notes

This plugin uses Tess-Two Tesseract Tools for integrating it for Android [https://github.com/rmtheis/tess-two/tree/master/tess-two]

This plugin is only for Android. More platforms will be supported soon.
