Final Release 4.12

January 2019 - News from our PDF universe

2018 is over; it was an exciting and successful year for us. We are already in “the middle” of 2019 and are looking forward to the new milestones and successes ahead.

In our “PDF Start 2019” information package, we have collected the latest developments, products, features and interfaces for the final release 4.12. It also includes application examples of our PDF Tools from our customers and publications/blog posts about document processes and quality.

Below is an excerpt of our technical and functional changes in the final release 4.12:

3-Heights™ PDF Web Viewer – The proven and tested PDF Web Viewer has been given new features and a new look. A new user interface offers a better user experience when utilizing the product – from desktops to smartphones. Intuitive context menus make working with annotations easier, and they can now be moved and scaled via touch. A rich text editor has been added to free text annotations, allowing an additional range of formatting options.

There are also numerous ways to adapt the viewer to the requirements of the application: default colors, functions such as save, thumbnails, outlines etc. can be enabled and disabled.

By the way: did you know that you can adjust the PDF Web Viewer to suit “your” corporate design, and its functionality and options can be individually tailored to meet your requirements?

3-Heights™ PDF OCR – New plug in available for the ABBYY 12 OCR engine for the 3-Heights PDF OCR Tool. 

This version also supports barcode recognition without the need for an OCR engine. 

By the way: the PDF OCR Tool enables streamlined and efficient text recognition processes. Intelligent identification and automatic recognition of the optimal OCR resolution for the document elements takes place before the OCR engine is used, meaning that your page volume is optimized, and text recognition takes less time. For even better performance, parallel processing within a single document is now possible.

Overall, the final release 4.12 offers numerous developments for solutions and components. 

The most important ones are:

  • PDF/A: Support for the new ZUGFeRD 2.0 standard “Factur-X” for hybrid electronic invoices
  • PDF Toolbox API: Extraction and modification (deletion and geometric transformation) of PDF page content
  • PDF 2.0: Support for the new AES-256 encryption (revision 6, replaces revision 5)
  • Digital signatures: Support for signed OCSP requests, OCSP requests via HTTPS etc.
  • TIFF Toolbox: Support for scanning TWAIN and WIA image acquisition devices for lossless image capture and processing. Go to TIFF Toolbox product page

Detailed information, as well as further information on other updates to our products, is available in the current release notes. If you have any questions, please feel free to contact us. We look forward to your feedback.

This spring, we will be taking part in two events in France. We are looking forward to seeing you there! Otherwise, you can keep up to date on our social media channels (Twitter, Facebook) or contact us directly about the topics you are interested in or those that you want to learn more about.

Save time thanks to cloud-based PDF services

iLovePDF and its community have evolved over the past years from a basic website to a globally used cloud-based service for editing and converting PDF documents. The steady increase in volume raised the need for more stability and quality in the software itself, as well as improved scaling with the current and future infrastructure.

Smallpdf is a big hit when it comes to compression

Attaching a large file to an email can prevent it from being sent or received due to technical limitations. In order to solve this problem, the founders of Smallpdf searched for a way to reduce the size of these files.
