What are the best practices for converting BMP files to other image formats like PNG using PHP, considering the lack of native support for BMP in GD library?

Converting BMP files to other image formats like PNG in PHP can be challenging due to the lack of native support for BMP in the GD library. One way to overcome this limitation is to use external libraries or tools that can handle BMP files and convert them to PNG. One popular option is the Imagick PHP extension, which provides support for various image formats including BMP. 

// Load the BMP file using Imagick
$image = new Imagick('input.bmp');

// Convert the BMP image to PNG format
$image->setImageFormat('png');

// Save the converted image to a new file
$image->writeImage('output.png');

// Clear memory
$image->clear();
$image->destroy();
