Full Working Example for Convert DOCX to JPG in PHP Using Aspose.OMR Cloud SDK

This example demonstrates how to use the Aspose.OMR Cloud SDK for PHP to convert a DOCX file into a JPG image.

<?php
require __DIR__ . '/vendor/autoload.php';

use Aspose\OMR\Configuration;
use Aspose\OMR\Api\ConvertApi;
use Aspose\OMR\Model\ConvertDocumentRequest;
use Aspose\OMR\ApiException;

// -----------------------------------------------------------------------------
// Configuration – replace with your actual credentials
// -----------------------------------------------------------------------------
$config = new Configuration();
$config->setAppSid('YOUR_APP_SID');
$config->setApiKey('YOUR_API_KEY');

// -----------------------------------------------------------------------------
// Initialize the Convert API
// -----------------------------------------------------------------------------
$convertApi = new ConvertApi($config);

// -----------------------------------------------------------------------------
// File paths (adjust as needed)
// -----------------------------------------------------------------------------
$inputDocxPath  = __DIR__ . '/input.docx';
$outputJpgPath  = __DIR__ . '/output.jpg';

// -----------------------------------------------------------------------------
// Prepare request – stream the input file to avoid loading whole file into memory
// -----------------------------------------------------------------------------
$inputStream = fopen($inputDocxPath, 'rb');
if ($inputStream === false) {
    throw new RuntimeException("Unable to open input file: $inputDocxPath");
}

$request = new ConvertDocumentRequest();
$request->setFile($inputStream);          // Input DOCX stream
$request->setOutputFormat('jpg');         // Desired output format
$request->setOutputFileName('output.jpg'); // Optional: name for the generated file

try {
    // -------------------------------------------------------------------------
    // Perform conversion
    // -------------------------------------------------------------------------
    $responseStream = $convertApi->convertDocument($request);

    // -------------------------------------------------------------------------
    // Write the resulting JPG to disk using a buffered copy (efficient for large files)
    // -------------------------------------------------------------------------
    $outputHandle = fopen($outputJpgPath, 'wb');
    if ($outputHandle === false) {
        throw new RuntimeException("Unable to open output file: $outputJpgPath");
    }

    while (!feof($responseStream)) {
        $buffer = fread($responseStream, 8192);
        if ($buffer === false) {
            throw new RuntimeException('Error reading from response stream.');
        }
        fwrite($outputHandle, $buffer);
    }

    fclose($outputHandle);
    fclose($inputStream);
    fclose($responseStream);

    echo "Conversion successful. JPG saved to: $outputJpgPath\n";
} catch (ApiException $e) {
    // -------------------------------------------------------------------------
    // Handle API errors (e.g., authentication, unsupported format)
    // -------------------------------------------------------------------------
    fclose($inputStream);
    echo 'API Exception: ', $e->getMessage(), PHP_EOL;
    exit(1);
} catch (Exception $e) {
    // -------------------------------------------------------------------------
    // General error handling
    // -------------------------------------------------------------------------
    if (is_resource($inputStream)) {
        fclose($inputStream);
    }
    echo 'Error: ', $e->getMessage(), PHP_EOL;
    exit(1);
}

Note: This code example demonstrates the core functionality. Before using it in your project, make sure to update any file paths and configuration values to match your actual environment, verify that all required dependencies are properly installed, and test thoroughly in your development environment. If you encounter any issues, please refer to the official documentation or reach out to the support team for assistance.

DOCX to JPG Conversion via REST API Using cURL

If you prefer a pure REST approach, the same conversion can be performed with a few cURL commands.

  1. Obtain an access token - replace the placeholders with your client credentials.
curl -X POST "https://api.aspose.cloud/connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET"
  1. Upload the DOCX file - use the token from the previous step.
curl -X PUT "https://api.aspose.cloud/v4.0/omr/storage/file/input.docx" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document" \
  --data-binary "@input.docx"
  1. Request conversion to JPG.
curl -X POST "https://api.aspose.cloud/v4.0/omr/convert" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
        "FileName": "input.docx",
        "OutputFormat": "jpg",
        "OutputFileName": "output.jpg"
      }' -o response.json
  1. Download the generated JPG.
curl -X GET "https://api.aspose.cloud/v4.0/omr/storage/file/output.jpg" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -o output.jpg

Breaking Down Convert DOCX to JPG in PHP with Aspose.OMR Cloud SDK

The following numbered breakdown explains each part of the PHP code that performs the convert DOCX to JPG in PHP workflow.

  1. Configuration Setup - The Configuration class holds your AppSid and ApiKey.
$config = new Configuration();
$config->setAppSid('YOUR_APP_SID');
$config->setApiKey('YOUR_API_KEY');
  1. API Initialization - An instance of ConvertApi is created with the configuration.
$convertApi = new ConvertApi($config);
  1. Preparing the Input Stream - The DOCX file is opened as a binary stream to avoid loading the whole file into memory.
$inputStream = fopen($inputDocxPath, 'rb');
  1. Building the Request - ConvertDocumentRequest specifies the input stream, the desired output format (jpg), and an optional output file name.
$request = new ConvertDocumentRequest();
$request->setFile($inputStream);
$request->setOutputFormat('jpg');
$request->setOutputFileName('output.jpg');
  1. Executing the Conversion and Saving the Result - convertDocument returns a response stream that is written to output.jpg using a buffered copy.
$responseStream = $convertApi->convertDocument($request);
$outputHandle = fopen($outputJpgPath, 'wb');
while (!feof($responseStream)) {
    $buffer = fread($responseStream, 8192);
    fwrite($outputHandle, $buffer);
}

For more details on the ConvertApi class, refer to the API reference.
