TesseractPlugin is not defined

[VitorHFLopes]

I don't know if is an issue or if I'm doing something wrong, but I'm getting "TesseractPlugin is not defined" when I try to call TesseractPlugin.loadLanguage or TesseractPlugin.recognizeText.

The project is building with success, but I'm having this problem, could someone help me?

Seems like you don't have this cordova-plugin-tesseract installed. Or maybe you just need to build your project again to make sure it was included.

Check if you have it installed by running following command on your terminal (inside your project folder): $ cordova plugin list

It should show cordova-plugin-tesseract in the list. If it's not, make sure to follow all steps in the README.

I have the same problem. TesseractPlugin is not defined. I believe I solved mine by calling window.TesseractPlugin. Now I'm getting errors "ReferenceError: deferred is not defined"

@Brain2000 The deferred thing is just an example object of deferred callback function.

Hey Please reply I am getting this Error : Cannot read property 'loadLanguage' I am using (window).TesseractPlugin.loadLanguage(language, function(response) { console.log('language', response); }, function(reason) { console.log('Error on loading OCR file for your language. ' + reason); });

Have you tried on a device?

Try these steps :-

1. Create blank Ionic Project in terminal ionic start myproject blank

2. Add plugin to project ionic cordova plugin add cordova-plugin-tesseract

3. Now navigate to E:\myproject\src\app\app.component.ts

   • add declare var TesseractPlugin; above @Component({..
   • then inside platform.ready().then(() => { } function add the functions as shown in readme.

4. Then in terminal ionic cordova run android

This knowledge is from here. It worked with another plugin. I will try it with this plugin soon and let you guys know if I have any luck. In the meantime posted this solution here for anyone looking for it.
