How can PHP developers utilize stream wrappers to handle image files in memory for PDF generation?

PHP developers can utilize stream wrappers to handle image files in memory for PDF generation by using the `data://` stream wrapper to read the image file contents into memory as a string. This allows for direct manipulation and embedding of the image data within the generated PDF file without the need to save the image to disk. 

// Read image file contents into memory using data:// stream wrapper
$imageData = file_get_contents('data://image/jpeg;base64,' . base64_encode(file_get_contents('path/to/image.jpg')));

// Generate PDF with embedded image
$pdf = new TCPDF();
$pdf->AddPage();
$pdf->Image('@' . $imageData, 10, 10, 100, 0, 'JPEG');
$pdf->Output('output.pdf', 'I');
