Laravel OCR Space

Laravel OCR Space is a package that allows you to use the OCR.Space API in your Laravel application for Optical Character Recognition (OCR).

Installation

You can install the package via composer:

composer require cdsmths/laravel-ocr-space

You can publish the config file with:

php artisan vendor:publish --provider="Codesmiths\LaravelOcrSpace\LaravelOcrSpaceServiceProvider" --tag="laravel-ocr-space"

Usage

Get a free Ocr.Space api key

You can get a free api key from ocr.space. This key is required to use the package.

You should add this key to your .env:

OCR_SPACE_API_KEY="YOUR API KEY"

Parsing an Image file

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Facades\OcrSpace;

$filePath = 'path/to/image.jpg';

$result = OcrSpace::parseImageFile(
    $filePath,
    OcrSpaceOptions::make(),
);

dd($result);

Parsing an Image URL

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Facades\OcrSpace;

$imageUrl = 'https://example.com/image.jpg';

$options = new \Codesmiths\LaravelOcrSpace\OcrSpaceOptions();

$result = OcrSpace::parseImageUrl(
    $imageUrl,
    OcrSpaceOptions::make(),
);

dd($result);

Parsing an base64 encoded image

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Facades\OcrSpace;

$base64Image = 'base64 encoded image';

$result = OcrSpace::parseBase64Image(
    $base64Image,
    OcrSpaceOptions::make(),
);

dd($result);

Parsing an binary image

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Facades\OcrSpace;

$binaryImage = file_get_contents('path/to/image.jpg');

// File type is required for binary images
$options = OcrSpaceOptions::make()
    ->fileType('image/jpg');

$result = OcrSpace::parseBinaryImage(
    $binaryImage,
    $options,
);

dd($result);

Parsing with parseImage method

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Facades\OcrSpace;
use Codesmiths\LaravelOcrSpace\Enums\InputType;

$filePath = 'path/to/image.jpg';

$result = OcrSpace::parseImage(
    InputType::File
    $filePath,
    OcrSpaceOptions::make(),
);

dd($result);

Options

You can pass options to the parseImageFile, parseImageUrl, parseBase64Image, parseBinaryImage and parseImage methods.

use Codesmiths\LaravelOcrSpace\OcrSpaceOptions;
use Codesmiths\LaravelOcrSpace\Enums\Language;
use Codesmiths\LaravelOcrSpace\Enums\OcrSpaceEngine;

// All possible options
$options = OcrSpaceOptions::make()
        ->language(Language::English)
        ->overlayRequired(true)
        ->fileType('image/png')
        ->detectOrientation(true)
        ->isCreateSearchablePdf(true)
        ->isSearchablePdfHideTextLayer(true)
        ->scale(true)
        ->isTable(true)
        ->OCREngine(OcrSpaceEngine::Engine1); // Engine1, Engine2, or Engine3

OCR Engines

OCR.Space provides three different OCR engines:

• Engine1: The original OCR engine, best for standard documents
• Engine2: Improved OCR engine with better accuracy for most use cases
• Engine3: The latest engine with significantly superior text recognition capabilities

You can specify which engine to use:

use Codesmiths\LaravelOcrSpace\Enums\OcrSpaceEngine;

// Use Engine 1
$options = OcrSpaceOptions::make()->ocrEngine(OcrSpaceEngine::Engine1);

// Use Engine 2
$options = OcrSpaceOptions::make()->ocrEngine(OcrSpaceEngine::Engine2);

// Use Engine 3 (recommended for best accuracy)
$options = OcrSpaceOptions::make()->ocrEngine(OcrSpaceEngine::Engine3);

Response

All methods return an instance of Codesmiths\LaravelOcrSpace\OcrSpaceResponse which has the following methods:

$response->getParsedResults(); // Returns an Collection `ParsedResult`
$response->getOCRExitCode(); // Returns the exit code
$response->getIsErroredOnProcessing(); // Returns a boolean
$response->getErrorMessage(); // Returns the error message
$response->getErrorMessageDetails(); // Returns the error message details
$response->getProcessingTimeInMilliseconds(); // Returns the processing time in milliseconds
$response->getSearchablePdfUrl(); // Returns the searchable pdf url
$response->hasSearchablePdfUrl(); // Returns if the response has a searchable pdf url
$response->hasError(); // Returns if the response has an error
$response->hasParsedResults(); // Returns if the response has parsed results

Parsed Results

If you want to get value from getParsedResults(), you can use the following methods:

$parsedResults = $response->getParsedResults();

$parsedResults->first()->getParsedText(), // Returns the parsed text from the first parsed result
$parsedResults->first()->getTextOverlay(), // Returns the text overlay from the first parsed result
$parsedResults->first()->getFileParseExitCode(), // Returns the file parse exit code from the first parsed result
$parsedResults->first()->getErrorMessage(), // Returns the error message from the first parsed result
$parsedResults->first()->getErrorDetails(), // Returns the error message details from the first parsed result
$parsedResults->first()->getSerializedParsedText(), // Returns the serialized parsed text from the first parsed result
