Usage

use Estey\EvernoteOCR\Client;

$client = new Client('YOUR DEV TOKEN');
$response = $client->recognize('path/to/image.jpg');

print_r($response);

The recognize method will return an array of TextBlock objects, each with an array of text recognition options. Each Text object contains the recognized text and a confidence score of 0-100. Each TextBlock contains the X and Y coordinates where the text was found and the width and height of the text block in pixels.

    [0] => Estey\EvernoteOCR\TextBlock Object

            [x] => 51
            [y] => 82
            [width] => 307
            [height] => 35

Laravel Filesystem Adapter

If you're using Laravel, there is a service provider available. Open app/config/app.php, and add the service provider to the providers array. You'll also need to add your Evernote Dev Token to your .env file with the key set to EVERNOTE_DEV_TOKEN.

'Estey\EvernoteOCR\Providers\Illuminate\EvernoteOCRServiceProvider'

Use it like so:

$client = App::make('evernote_ocr', ['path/to/image.jpg']);
$response = $client->recognize();

print_r($response);

Flysystem Adapter

The Evernote OCR package comes with a built in adapter to support the Flysystem filesystem library.

use Estey\EvernoteOCR\Client;
use Estey\EvernoteOCR\FileAdapters\FlysystemFileAdapter;
use League\Flysystem\Filesystem;
use League\Flysystem\Adapter\Local as Adapter;

$filesystem = new Filesystem(
    new Adapter(__DIR__ . '/path/to/root/')
);

$client = new Client('YOUR DEV TOKEN');
$file = new FlysystemFileAdapter('path/to/image.jpg', $filesystem);
$response = $client->recognize($file);

print_r($response);
