What are some common challenges when converting dynamic images into PDF files using PHP?

One common challenge when converting dynamic images into PDF files using PHP is ensuring that the image quality is maintained during the conversion process. To solve this issue, you can use the TCPDF library in PHP, which provides functions for adding images to PDF files with high quality.

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Add a page to the PDF
$pdf->AddPage();

// Set image quality
$pdf->setImageScale(1.53);

// Add image to PDF
$pdf->Image('path/to/image.jpg', 10, 10, 100, '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false);

// Output PDF
$pdf->Output('output.pdf', 'D');
