Background image size for PDF mail attachments

Hello,
I need attach PDF document form with subscriber data to mail. But I can't to place Background image (A4 organization document form with header and footer) to fill the A4 page strictly; in result PDF Background image (jpeg or png file) stretches approximately 4 times. It not depends from Background image resolution. Is it technique to fill A4 page document with Background image?

Hi,

I'm sorry for your trouble.
I looks, as if maybe there is a problem with the scaling, because this is the second time, such a problem is reported.
The other user solved the problem the following way:
They created an image 7000 x 5000 Pixel and put the Background-Image with a resolution of 3508 x 2480 px (= A4) into the upper right corner. The rest was just filled with the background-color.
This obviously is a workaround, which hopefully will work for you, too.
I will try to check into the feature as soon as possible and provide a more adequate solution.

Hi,
I create this file (with black background-color). Result see in file.

After investigations on my site the temporary solution:
1) Image 7000 x 9800 (wight x height) pixels;
2) Background-Image with a resolution of 2480 x 3508 px into the upper LEFT corner.

Hi,

I was finally able to look into this problem.
This actually is a bug in Visforms since Version 3.13.9.
For security reason, I switch to a newer version of the tcpdf library, then.
Because this newer version has modifitions to the way, how the page size is messured, I had to adapt my code.
Basically there is now a miscalculation in the page size, that effects the calculation of the background image size.

I will release a bugfix as soon as possible.
Here is the modified code.

Open administrator\components\com_visforms\helpers\pdf\visTCPDF.php
(please make sure that you have a backup of the file, before you make any modifications).

Replace the code at line 43 and 44

After that, using the original background image with the proper 2480 x 3508 solution should work.

Now all work fine. Thank you, Aicha.
