Images in .pdf Invoice

[Joseph Mohan]

Any other things i'm missing with regards to getting an image into the .pdf invoices?

Set the url to a full path

Tried .png/.jpg 

Nothing...

Any ideas?

[Eduardo Rivas]

Well, Cartridge uses Pisa to create the PDFs. Apparently you can pass a "link_callback" arg to CreatePDF(). This callback should handle the conversion of the relative path of the image in the HTML to the complete filesystem path to be embedded in the document.

The xhtml2pdf docs provide a full example. You'll need to override the invoice view to pass the callback to CreatePDF().

Hi,

Have you tried different browsers? I had a strange anomaly with pdfs in mezzanine that turned out to be browser specific.

Cheers,

Ag

Thanks for your help. 

I've spent the last 2 days pulling xhtml2pdf apart and still cannot get this to work. It seems to just not recognize any src attribute on an img tag, even tried brute forcing it but 

xhtml2pdf also seems to now be abandoned and their python3 support is shaky.. hense why i'm struggling so much.

Had a quick look at weazyprint but having trouble installing it on my dev machine let alone my production shared servers....  

Anyone had any luck using an alternative to xhtml2pdf?

Outside the scope of Mezzanine/Cartridge, I am getting amazing results using athenapdf to convert HTML to PDF. I manage a sprawling Python application that had a homebrew and long-in-the-tooth webkit integration in c++ and Python to generate PDF. I replaced it with http calls to the athenapdf microservice. The performance and quality have been astounding.

I'm not sure if this will help you or not, but I developed a replacement library for xhtml2pdf (though not a drop-in):

https://github.com/sjkingo/pywkhtmltopdf

[Eduardo Rivas]

I've also used wkhtmltopdf but with the Django bindings. It's available on Pypi as django-wkhtmltopdf (that's off the top of my head, you should check) and provides a class based view and PDF response type.

Cool Sam!

Do you think we should use your library in Cartridge instead of whatever's being used now?

I'd say probably use the one Eduardo suggests: https://github.com/incuna/django-wkhtmltopdf since it is has more seamless support for Django and does the same thing as mine (calls out to the wkhtmltopdf static binary).

Mine is for more low level, generic Python usage, though I do use it for a large Cartridge site successfully.

Would you like me to raise an issue and investigate if one would work better for Cartridge?

That actually sounds more suited to what Cartridge needs - the PDF integration is just a couple of lines. 

I also think that you both owning the library, and also being a long-time Mezzanine contributor, is worth a lot, if the difference between the two libraries is negligible in what we're doing.

That'd be awesome, thanks!

Thanks Stephen - I've opened an issue to track this: https://github.com/stephenmcd/cartridge/issues/298

[Joseph Mohan]

Sam you are an absolute gent!

Works an absolute treat, images work fine, and formatting is spot on. 

Thank you
