Convert HTML to a PNG Image Array in PHP
1 min readAug 4, 2021
Converting just about any file format to an image can be quite the ordeal if you’re attempting it manually; between rendering the file, rasterizing it into an image, and splitting the image into pages, you can be looking at a significant amount of processing time. However, by utilizing the following API in PHP, you can instantaneously convert HTML to a PNG image array, one for each page.
To begin the operation, we run this command to install the SDK:
composer require cloudmersive/cloudmersive_document_convert_api_clientNext, we can call the function by inputting the HTML file into the following code — if you are using external files in your HTML (such as images), you will input an absolute URL to the file instead.
<?php
require_once(__DIR__ . '/vendor/autoload.php');// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');$apiInstance = new Swagger\Client\Api\ConvertDocumentApi(
new GuzzleHttp\Client(),
$config
);
$input_file = "/path/to/inputfile"; // \SplFileObject | Input file to perform the operation on.try {
$result = $apiInstance->convertDocumentHtmlToPng($input_file);
print_r($result);
} catch (Exception $e) {
echo 'Exception when calling ConvertDocumentApi->convertDocumentHtmlToPng: ', $e->getMessage(), PHP_EOL;
}
?>
And boom, we’re done! Nothing to it.
