When I press for a PDF to be created I get this line on the PHP_ERROR:

[23-May-2016 23:14:27 Europe/Paris] PHP Warning: Illegal string offset 'hex' in components\com_invoices\helpers\dompdf\include\style.cls.php on line 1418

It is not major since it works but still there is something going on!!

oh, I see. I'll take a look. In any case it's probably not important, since it's just a warning and doesn't affect the PDF itself..

I am getting the same error, do you know if there is a resolve for it:

Warning: Illegal string offset 'hex' in components/com_invoices/helpers/dompdf/include/style.cls.php on line 1418

Fatal error: Call to undefined function imagecreatefrompng() in /components/com_invoices/helpers/dompdf/lib/class.pdf.php on line 4258

Hi Germinal, thanks very much for your help.

To be more specific, I first was not able to get it installed by using the Joomla extension installer so I manually moved the files into here:

components/com_invoices/helpers/dompdf

as per the installation instructions. Everything else works except that. It did not work before adding the logo. I left the template as is, with line #3...

and in the template I uploaded the logo using the "company logo" update option. I removed it and the problem still exists.

Thanks again for your help.

Also, it only happens when you click the "download PDF" option in the admin and the front end. It goes to:

/index.php/1-invoice-1000?format=dompdf

Warning: Illegal string offset 'hex' in /components/com_invoices/helpers/dompdf/include/style.cls.php on line 1418

Fatal error: Call to undefined function imagecreatefrompng() in /components/com_invoices/helpers/dompdf/lib/class.pdf.php on line 4258

I have read that this has been fixed in "dompdf" v. 6.0 in a few places, here is one link: https://github.com/sliknl/dompdfbundle/issues/9

What version is the one sent in the install?

Hi Germinal. Do you know of a resolve for this because we can't do a PDF download and therefore can't bill a customer. Do you want SFTP or SSH access?

Thanks for your help.

Ok I fixed it!

I am on CentOS 7 with PHP 5.6 and I had to manually install the following two packages:

php-tcpdf
and
php56-php-pecl-pdflib

and it works fine.

Thanks for your support Germinal and offering to work on our server.
