What potential issues can arise when converting PDF to PNG using Imagick in PHP?

One potential issue that can arise when converting PDF to PNG using Imagick in PHP is the loss of image quality or resolution. This can happen if the default settings for the conversion are not optimized for preserving the quality of the PDF content. To solve this issue, you can adjust the resolution and compression settings in the Imagick constructor to ensure a higher quality output. 

// Set the resolution and compression settings for better quality output
$imagick = new Imagick();
$imagick->setResolution(300, 300); // Set resolution to 300 DPI
$imagick->setImageCompressionQuality(100); // Set compression quality to 100%
$imagick->readImage('input.pdf');
$imagick->setImageFormat('png');
$imagick->writeImages('output.png', false);
