mPDF 5.7.1 - image displays as a broken [x]

I have a small issue with mPDF (version 5.7.1).

This code should generate PDF with image file:

 $mpdf = new mPDF();
 $html = '<img src="https://www.google.pl/images/srpr/logo11w.png"/>';
 $mpdf->WriteHTML($html);
 $mpdf->debug = true; 
 $output = $mpdf->Output(); 
 exit();

Well there is no image but an [x] instead.

I've googled enough to get to the conclusion that it has to be done this way but I also tried realpath to the file. Still nothing.

The only thing I haven't tried is <img src="logo11w.png"> and copying the image into the folder because I don't know into which folder I should copy file logo11w.png.

Any suggestions?

Solution

  • I had the same problem with PNG images being displayed as [X] when to generate PDFs with mPDF.

    I added: $mpdf->showImageErrors = true;

    After: $mpdf = new Mpdf();

    and got the error message:

    GD library required for PNG image (alpha channel)#

    So after running apt-get install php5-gd generating a PDF with a PNG worked like a charm!
