Are there any best practices for converting JPEG images to XPM format using PHP?

When converting JPEG images to XPM format using PHP, it is important to maintain the quality and color depth of the original image. One way to achieve this is by using the GD library in PHP to manipulate the image data. By resizing the image and converting it to the XPM format, you can ensure that the resulting image maintains its quality. 

// Load the JPEG image
$jpegImage = imagecreatefromjpeg('input.jpg');

// Create a new image with the same dimensions
$xpmImage = imagecreatetruecolor(imagesx($jpegImage), imagesy($jpegImage));

// Copy the JPEG image to the XPM image
imagecopy($xpmImage, $jpegImage, 0, 0, 0, 0, imagesx($jpegImage), imagesy($jpegImage));

// Save the XPM image
imagepng($xpmImage, 'output.xpm');

// Free up memory
imagedestroy($jpegImage);
imagedestroy($xpmImage);
