4­-Heights™ PDF Toolbox SDK

As we approach the beginning of the second quarter of 2021, we would like to share our most recent product update, concerning PDF manipulation for mass-editing and mass-creation of PDF/A-compliant documents. One of our customers’ success stories describes an actual use case scenario, where our product PDF Toolbox was implemented to help create Swiss adoptions of European and international standards.

Our second success story illustrates how validation and document conversion to PDF/A can work together to archive digital documents in a legally compliant manner.

We wish you a great reading and happy easter!

PDF Toolbox SDK: Precise PDF Manipulation

4-­Heights™ PDF Toolbox SDK is a fast, high-quality, PDF/A-compliant component to programmatically create PDF documents from scratch, add and extract any content, such as text and images to/from existing PDFs and assemble PDF documents (merge and split). Thanks to its various interfaces, this SDK can be used with Java, C/C++, .NET Core and .NET languages such as C# and Visual Basic. It is available for Windows, Linux and macOS.

This advanced component is all about fine granular PDF manipulation at the document, page and object level. Here is a short overview of its main features:

  • Forms and Annotations: Create, fill and extract forms programmatically. Add, modify and extract annotations.
  • Edit PDF: Change PDF documents. Add additional information, such as a stamp, image or text or remove text from a PDF.
  • Create PDF: Programmatically create PDF/A-compliant documents and new pages with any content. Make a new PDF or merge them with your existing PDFs. Some of the most common areas of use for these advanced developer features include mass production of invoices and reports, PDF creation “on the fly” in web server applications, “save as PDF/A” function in application programs, importing images and text in PDF/A documents. Even though the 4­-Heights™ PDF Toolbox SDK is the successor of the 3­-Heights™ PDF Toolbox API, all main product features and use cases remain the same.

The main differences are a simpler and clearer use of terminology that causes less ambiguity and an interface that is more intuitive and easier to use. The additional focus on simplicity is an important characteristic of our 4-­Heights™ product generation.

There are also smaller improvements made in terms of performance like the ability to copy multiple pages and page ranges all at once; and jointly opening PDF and FDF files at the same time.

PDF Toolbox SDK: Upcoming Features

In case you are using our 3-Heights® PDF Toolbox API, please note that this product is still 100% functional and up to date. However, our upcoming features will only be available on the newest version: 4-­Heights™ PDF Toolbox SDK.

Some of these upcoming features include:

  • Creation of both internal and external link destinations
  • Creation of text markup annotations: strike-through, underline and highlight annotations, etc.

If you are interested in migrating from 3-­Heights™ to 4-­Heights™ for this specific product, please get in touch with our technical support. Migrating is simple with the assistance of our migration guides, migration script (source code migration) and also due to the fact that the interface structure remains the same.


SUCCESS STORY: Creating Swiss adoptions of European and international standards in record time

The Swiss Association for Standardization (SNV) is responsible for enabling and promoting standardization activities in Switzerland. As part of that responsibility, they publish national standards and adoptions in German, French and English. Some of the more popular adoptions contain content in more than one language. At the time of writing, SNV publishes around 5’000 complex documents per year.

In the past, SNV’s publishing team created each adoption in each language by manually editing PDFs. This was a very time consuming and somewhat error-prone process, making it a real challenge to keep up with the demand to publish an ever-increasing number of documents in more formats and consistently maintain the high-quality required. Thus, a new and more automated approach was required. Discover how our 3-Heights® PDF Toolbox was implemented.

SUCCESS STORY: Document conversion to PDF/A, validation and long-term digital archiving

On our last newsletter we have mentioned how important it is for archived documents to meet certain criteria. On the one hand, these requirements can be of a purely technical nature, but on the other hand, they might be mandatory by law to be legally valid. This was precisely the case for one of our new customers, Geovap spol. s r. o. from the Czech Republic. GEOVAP needed an integrated and comprehensive solution for its document management software to convert various document formats to PDF/A for long-term archiving. This included doc, pdf, xls, txt, png, jpg, eml, msg and more. Find out how Geovap spol. s r. o. implemented our 4-Heights® Conversion Service.
