Anyline React-Native Plugin

Anyline is mobile OCR SDK, which can be configured by yourself to scan all kinds of numbers, characters, text and codes.

The plugin lets you connect to the SDK with React-Native.

Example

Go to the Example project in the example folder.

Check out the examples ResultView.js and config.json to see the implementation.

Quick Start Guide

1. Get a License

Go to our pricing page and get your license or sign up for your expiring test license.

2. Get the Anyline react-native plugin

Download or Clone the Repo to your node_modules

project   
│    android.index.js
│    ios.index.js
└─── node_modules
     └─── anyline-ocr-react-native-module

or just go

 npm i anyline-ocr-react-native-module

Link the project. Run in root:

react-native link

in the root folder.

3. Get the native Dependencies

Android

Setup Packages

Package name must match with the bundleID from your Anyline License.

Add Anyline Package

Go into the native Android folder of your Project to your MainApplication.

Import the AnylinePackage

import com.anyline.reactnative.AnylinePackage;

and add the package to your getPackages function

@Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
            new AnylinePackage()
      );
    }

Issues

Strict mode does not allow function declarations in a lexically nested statement.

duplicate files during packaging of APK

packagingOptions {
  pickFirst 'lib/armeabi-v7a/libgnustl_shared.so'
  pickFirst 'lib/x86/libgnustl_shared.so'
}

iOS

Disable bitcode in your project

Podfile

• Copy the Podfile from our example Project to your native iOS root folder.
• Change the target of the Podfile to your project name.
• pod update

Permissions

Add Camera Permissions to Info.plist

Privacy - Camera Usage Description

Add also every other permission you want to configure in your config.js (vibrate, sound).

Anyline License

Your BundleIdentifier of your app has to match with your bundleID from your Anyline License.

4. Import the plugin to your JavaScript file

import Anyline from 'anyline-ocr-react-native-module';

5. Import the config file

import config from './config.js';

Add and import a JSON file with the proper structure and elements. The JSON config contains:

1. The license key

2. Options field with

• AnylineSDK config parameter
• “segment”: which contains the scanModes for the UI Segment (e.g. switch between Analog and Digital) - optional

3. OCR field with (Only if you want to use the OCR module)

• your custom training data
• RegEx Validation

If you want to get detailed information on the config JSON, go to ourdocumentation.

6. Call the Anyline component

AnylineOCR.setupScanViewWithConfigJson(
        JSON.stringify(config),
        “ANALOG_METER”,
        this.onResult,
        this.onError
    );

7. Add custom TrainData to the OCR Module

If you want to add you custom traindata, you have to copy it into the native project folder.

iOS

ios   
└─── trainedData
     └─── myTrainedData.traineddata

Android

android   
└─── app
      └─── src
            └─── main
                   └─── assets
                          └─── traindData
                                  └─── myTrainedData.traineddata

Also the OCR Config has to reflect the path.

Props

Key	Type	Default	Description
config	string	*required	config (JSON String)
scanMode	string	*required	Will set the scanMode/Module of the Plugin.
onResult	function	*required	The function you pass will be the onResult callback. Use this callback to handle the found scan results.

Keep in mind, that you have to add every permission to your project, you add in the config (vibrateOnResult -> vibration permission)
