How to display a JSON/base64 encoded image in FPDF?

Question

I\'m storing signatures (using signaturepad in my database Coldfusion/MySQL 5.0.88 and would like to output the signature I\'m taking onto a pdf which I\'m gene

Answer 1

The issue is here

$pdf->imagepng($img);
                 ^-------------- This should be an image path (String)

Solution

$file = 'signature.png' ;
imagepng($img, $file);  
                 ^----------- Save Image to File Instead 

Then

if ($imgProceed == "true") {
    $pdf->imagepng($file);
} else {
    $pdf->Cell(50, 4, '', 0, 1);
}
