Printing issue 20.14.0

[toejam34]

Team,

I have just updated to 20.14.0 and I get an error :

Steps to reproduce :

Admin panel --> Sales --> Invoices --> Click invoice -- > print

`There has been an error processing your request
Exception printing is disabled by default for security reasons.

Error log record number: 756294071196

If I dump the report it shows

a:5:{i:0;s:50:"Corrupt PNG Image. Mandatory IDAT chunk not found.";i:1;s:1770:"#0 /home/nginx/domains/seriouslylotus.com/public/vendor/shardj/zf1-future/library/Zend/Pdf/Resource/ImageFactory.php(54): Zend_Pdf_Resource_Image_Png->__construct() #1 /home/nginx/domains/seriouslylotus.com/public/vendor/shardj/zf1-future/library/Zend/Pdf/Image.php(124): Zend_Pdf_Resource_ImageFactory::factory() #2 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Sales/Model/Order/Pdf/Abstract.php(137): Zend_Pdf_Image::imageWithPath() #3 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Sales/Model/Order/Pdf/Invoice.php(101): Mage_Sales_Model_Order_Pdf_Abstract->insertLogo() #4 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Adminhtml/Controller/Sales/Invoice.php(107): Mage_Sales_Model_Order_Pdf_Invoice->getPdf() #5 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Adminhtml/controllers/Sales/Order/InvoiceController.php(470): Mage_Adminhtml_Controller_Sales_Invoice->printAction() #6 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Core/Controller/Varien/Action.php(410): Mage_Adminhtml_Sales_Order_InvoiceController->printAction() #7 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Core/Controller/Varien/Router/Standard.php(256): Mage_Core_Controller_Varien_Action->dispatch() #8 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Core/Controller/Varien/Front.php(174): Mage_Core_Controller_Varien_Router_Standard->match() #9 /home/nginx/domains/seriouslylotus.com/public/app/code/core/Mage/Core/Model/App.php(349): Mage_Core_Controller_Varien_Front->dispatch() #10 /home/nginx/domains/seriouslylotus.com/public/app/Mage.php(743): Mage_Core_Model_App->run() #11 /home/nginx/domains/seriouslylotus.com/public/index.php(50): Mage::run() #12 {main}";s:3:"url";s:102:"/index.php/adminpanel/sales_order_invoice/print/invoice_id/38091/key/fda4de95cf1e90b25326f415ff27d4b6/";s:11:"script_name";s:10:"/index.php";s:4:"skin";s:7:"default";}

Any help would be appreciated!

This appears to be loosely related to the logo found in system --> sales --> invoice and packing slip design.

If I remove the logo for PDF print outs then it works. Add it back in it fails.

I have tried multiple formats.

When you say multiple formats, which formats have you tried? There are some PNGs that Zend doesn't support but most common ones should work and if you use a different format altogether like JPG then there is no way it should cause this error.

Hi , thanks for the response. I have tried jpg and redone the png. All result in the same issue. The only way around is no image! Sent from my iPhone On 23 Jun 2025, at 17:39, Colin Mollenhour ***@***.***> wrote: When you say multiple formats, which formats have you tried?

I don't see how it could be trying to load the jpg as a png unless you're uploading the jpg with a .png extension: https://github.com/zf1s/zf1/blob/master/packages/zend-pdf/library/Zend/Pdf/Resource/ImageFactory.php#L45

I haven’t changed the file. It’s the same as was working it the previous version. Sent from my iPhone On 23 Jun 2025, at 18:57, Colin I have edited this to make it cleared to read as replied via email

I’ll revise that - I hadn’t changed the file until it stopped working in the current version. Sent from my iPhone On 23 Jun 2025, at 18:57, Colin

I reproduced the issue and found the bug but it looks like it was already fixed - just the fix was not released yet:

Thats great! thanks.

How do I apply the fix? I am experienced in VMWare/Wintel not this! :)

Do you know anything about this @sreichel ? It seems the public $value; line somehow made its way back into 1.24.3.
