Present and Future of Quick PDF Library

By Karl De Abrew, President of Foxit SDK, BU

After sixteen years, thirteen major versions (count ‘em!) and countless patches, we have taken Quick PDF Library from zero to hero; a modest one-man library to an awesome development product used by thousands of companies around the world.

But, the one thing that has not changed is our vision for the product. We see Quick PDF Library’s as a simple-to-use SDK (and low-cost!) that provides reliable functionality for the majority of PDF files.

n.b. of course, if you are looking to cover the niggly edge cases, then the big brother Foxit SDK is available for you, admittedly at a higher price point.

As you’d expect, being part of the big Foxit Software family we’re actively working on improving, updating, and optimising Quick PDF Library. We have more access to development resources and talent. This is shown in our two best version releases to date: v13, last year, and v14, which is releasing this Thursday. We still believe in the core principle that brought us to our current position: we can provide real PDF value to the small-to-medium sized business.

Moreover, you will be happy to see that we will be offering promotional prices for upgrades to v14, as well as new licenses, for a limited time, starting Thursday.

Finally, for people that have reported bugs and missing functionality for the Library, thank you. Your reports help us make Quick PDF Library bigger and better with every version. Our support team works to fix them as quickly as possible, and, on Thursday, you will see many of the issues you experienced in v13 have now been resolved in v14.

I look forward to seeing your thoughts on Quick PDF Library v14.

Best regards,
Karl De Abrew, President of Foxit SDK

ZUGFeRD – the electronic invoicing standard sweeping across Europe

This might be the first time you’ve heard the word ZUGFeRD, but those working with the European market should take note – it’s set to be adopted across the EU.

ZUGFeRD, standing for the Central User Guide for Electronic Invoicing in Germany, was developed to add long-needed standardization to the e-invoicing format.

Flat PDF invoices (or, heaven forbid, Word Docs) are easy for humans to read, but it’s not an easy task to input the information into ERP, accounting or archiving programs. In contrast, Electronic Data Interchange (EDI) has been used to transmit invoice information between large companies – but the format is incomprehensible to a human reader.

EDI uses structured data to move the invoice information from machine to machine, with little human involvement necessary. However, to implement it requires a bilateral agreement between two companies, agreeing what data is to be shared and how it will be structured. As the data is not for a human reader, software to process the invoice must be developed or purchased.

The ZUGFeRD standard aims to bring the benefits of EDI – lower processing costs, reduced human error, ability to automate processes – within the reach of companies that may only need to process invoices sporadically, or don’t have the resources to implement EDI systems.

It does this by aiming for the best of both worlds. An XML file containing the structured invoice data is embedded within the PDF. The XML data can easily be pulled out by machine, and as it follows a standard format, no bilateral agreement is needed. For the those who want to manually check an invoice, the PDF shows all the information in clear, human-readable form.

Another important benefit is that the the ZUGFeRD standard makes use of and expands on the PDF/A format for long-term digital archiving. PDF/A is already widely used to store digital invoices, however, the format is still not optimal for extracting the invoice data without human intervention. Attaching the XML file means both can be stored together for records. Similarly to the PDF/A format, ZUGFeRD is a non-proprietary standard.

ZUGFeRD’s final version was released in Germany in June 2014, and work is already underway to make it a national standard – but its international ambitions have been clear from the start. ZUGFeRD is based on existing EU and international standards, so get ready to see it adopted at least continent-wide before long.

The German e-invoicing forum has worked hard to ensure that the ZUGFeRD standard will not rely on any third party software. The full specification is freely available from their website.

Here at Debenu, we’re keeping an eye on these developments and adding ZUGFeRD features to our Quick PDF Library. Whether you’re looking to expand your existing apps, or building completely new ones, the next release of Quick PDF Library will include functions to create and read ZUGFeRD invoices.

Greener, faster, postage – How Zelená Pošta use Quick PDF Library 13

What if you could reduce postage costs by 60%, and never stand in a post office queue again?

Slovakian company Zelená Pošta are making it a reality. The idea is simple: you send your letters to them, in .PDF format, they print them, put them in an envelope, and send them out for you. No more waiting in line, no more digging around for stationery, and much, much less printing – at least for you anyway.

Not just for outgoing mail, Zelená Pošta is also expanding their service in the other direction. You can sign up to receive your paper mail to your email as soon as the sender joins their network.

They are taking the concept of paperless office to the next level.

With PDFs still king of the electronic documents, Quick PDF Library 13 by Foxit Software was the natural choice for their developers. Adrián Csuba, CEO at Zelená Pošta says, “In our scenario, we have a node-WebKit application that starts an external process when processing the PDFs. This external process is implemented in C++ and uses the library to split, merge, print and sign the PDF files.”

“The application downloads this executable file from our server whenever a newer version is available. For us, it’s easier to maintain C++ application than the Delphi one, that’s why we are interested in the LIB version of the Quick PDF Library.”

While Zelená Pošta is working hard to save time and money for their customers, Quick PDF Library works hard to save time (and money) for them. Its efficiency gives them a huge advantage when manipulating large source files.

“We use the library for creating multiple PDF documents from single PDF file. With other solutions, the performance of this approach usually drops dramatically with 1000+ page source documents. With Quick PDF Library, the performance is much better; my test case finished in 50 seconds, which is 60% faster than the workaround.”

Quick PDF Library is regularly updated with new features with expanded functionality, helping companies like Zelená Pošta stay ahead of the competition.

Their verdict? “Your library is awesome and we’ll keep evaluating over the next few weeks to try the newest version.”

You can try Quick PDF Library for free today.

For example, if you own a Single Developer License + Standard Upgrade Protection for version 10 of Debenu PDF Viewer SDK then you will need to purchase the Single Developer Upgrade License + Standard Upgrade Protection (11.x to 12.x) product in order to upgrade to version 12 -— though you can choose to buy the Premium Upgrade Protection version of that product if you prefer.
