What are some potential libraries or tools that can be used to convert RGB RAW files to PNG in PHP?

Converting RGB RAW files to PNG in PHP can be achieved using libraries or tools that support image processing. One popular option is the GD library, which is a built-in PHP extension for creating and manipulating images. Another option is the Imagick extension, which provides more advanced image processing capabilities. Both libraries can be used to read RAW files, convert them to PNG format, and save the resulting image.

// Example using GD library
$rawFile = 'input.raw';
$rawData = file_get_contents($rawFile);
$image = imagecreatefromstring($rawData);
if ($image !== false) {
    imagepng($image, 'output.png');
    imagedestroy($image);
}

// Example using Imagick extension
$rawFile = 'input.raw';
$im = new Imagick();
$im->readImageBlob(file_get_contents($rawFile));
$im->setImageFormat('png');
$im->writeImage('output.png');
$im->clear();
$im->destroy();
