TCPDF errors related to VM products

[en jie rudd]

Hello everyone

I have been have recently run into an issue with TCPDF errors related to VM products. I have searched the forum and most of the discussions are pointing to the shipment images vs TCPDF, but nothing (as far as I could find) to vm products.

I have been getting a long list of 'soft 404' errors from GWMT recently and the list expends by day all end up with 'https://www.example.com/example_VM_product.html?format=pdf&tmpl=component';. When searched the the link source, there is this error report of 'TCPDF ERROR: [Image] Unable to get the size of the image: /images/stories/virtuemart/product/example_VM_product.jpg'. The list appears to be going to cover all my VM products eventually. All my product images are in jpg and they have always been (but not such issue before).

I have recently upgraded to a new template:
template: Gavick Storefront
Joomla: 3.6.3
VM: 3.0.18
tcpdf: 1.0.2

I have search the forums and my developer has tried almost all recommendations out there without luck.

Any help, advice or recommendation will be greatly appreciated.

best regards

TCPDF ERROR: [Image] Unable to get the size of the image: /images/stories/virtuemart/product/example_VM_product.jpg'

dos not mean that TCPDF cannot handel this type of file, but that tcpdf do not find or cannot convert it.
So i think the probel is that image do not use full path.
TCPDF like JPATH_ROOT.'/images/stories/virtuemart/product/example_VM_product.jpg or can handel  https://www.example.com/images/stories/virtuemart/product/example_VM_product.jpg, but fail if is not configured properly with relative paths.

Hello Studio 42

Thank you very much for your time and reply.

As I am not familiar with the TCPDF configuration, any advice on how this could be correctly configured?

Best regards

there is a long post on here somewhere with me, Max and Alatak  about the path for images for TCPDF  .. from memory it was a server thing...

There is no configuration for TCPDF. In default VM TCPDF is used for invoice creation and not in the product page.

You don't give any version history but I wonder if this would help:  http://forum.virtuemart.net/index.php?topic=135774.msg473425#msg473425

VMTCPDF is for orders PDF, TCPDF is the library used by default with the PDF view, so this sould work for any component that can use format=raw.
But the current PDF document default render is not including full paths and this need fixes
(note that this was working with old tcpdf main class)
If you need a way to render any HTML as PDF read : http://studio42.github.io/joomla-pdf-document-view/index.html
And install what you need. This should work for any components adding &format=pdf in the llink.
I don't know if this fix the problem for images, but if you can install wkhtmltopdf, then you have a perfect render(see my test http://studio42.github.io/joomla-pdf-document-view/perf.html)
And to isntall it : http://studio42.github.io/joomla-pdf-document-view/install.html
You can install all class, if you watn compare results, some are big and you have to add the files manually in your Joomla folders.

On a clean J3.6.3, VM3.0.18 and com_tcpdf_1.0.2 with Protostar & default VM templates there is no problem with the pdf rendering of the product page. 

Which would lead to the possibility of a Gavick template issue or the problem that some have had following "upgrade" to J3.6.3 on sites that have been upgraded from very old VM versions, solved by deleting the root/components/com_tcpdf directory.

Hello everyone

Thank you very much for your replies and support.

I have now: deleted the root/components/com_tcpdf directory (although my site was upgraded from VM 2.5 to VM 3.0.

I will monitor the error reports before taking the next step.

I will also keep this post updated.

Hello all helpers

I have been monitoring this for a few weeks now:

• the errors are still appearing, but not the speed as before (Additional info: my admin back end is happy to create invoice for Paypal payment orders, but when was done by credit card payment, it has a message as 'force creation of invoice'. I first thought this may relate to the error, but the products with the error messages are not exclusive to these 'forced created invoices' products - seems to be random to me.
• I deleted 'root/components/com_tcpdf' as suggested, but it just rebuilt itself somehow. This time I renamed the directory. I will watch for while again and feedback here.

Best regards

Hello

I ran with VM 3.0.18 and JM3.6.5 and TCPDF library from Virtuemart 3.0.18 package (com_tcpdf_1.0.2.zip - tcpdf library 6.2.12) into the same

TCPDF ERROR: [Image] Unable to get the size of the image: .......

problem in my live site.

My site is based on Joomlart JA Hawkstore template.

For probing I made fresh localhost install from JA Hawkstore quickstart (J 3.4.8 and VM 3.0.9), update Joomla and Virtuemart. Here tcpdf library version is 6.0.096 + several additional files copared with com_tcpdf_1.0.2.zip
After that I deleted from  my livesite /libraries/tcpdf folder, copied from fresh installation the tcpdf folder to live site and pdf's for products started to work.

Because pdf's for products did't work with com_tcpdf_1.0.2 and Protostar template either, I'm afraid that some misconfiguration is inside  com_tcpdf_1.0.2 library.

Try to use jpg image, to be sure it's not a image format compatibility issue.
