Summer release of Java PDF library adds PDF OCR, digital signature enhancements including latest AES 256 encryption

Atlanta, GA August 12 2013 – Qoppa Software’s summer release of Java® PDF component and library products delivers a new OCR module, digital signature enhancements including latest AES 256 algorithm and many other improvements.

Qoppa Software is pleased to announce a new Java PDF OCR library sdk which supports all Latin-based languages including English, German, French, and Spanish and is available for Windows®, Mac OS X® and Linux®, in 32 and 64 bit. This is a clean, production-level Java integration of the well-known Tesseract engine and Qoppa’s own PDF rendering and editing technology.

This release also contains many digital signature enhancements including PDF certifying signatures, often used in document workflows to approve documents before publication. A certifying signature is the first digital signature applied to a PDF document and allows specifying what subsequent changes may be made to the certified document.

Appearance of digital signatures was improved to allow validation of multiple signatures. Since the PDF format does not inherently support multiple digital signatures, Qoppa’s PDF engine is parsing for the content added after a signature and identifying which changes are acceptable and which changes invalidate the signature.

The new AES 256 encryption algorithm (R=6) has been implemented and allows encrypting or decrypting PDF documents with the highest level of security available. This algorithm is defined in the upcoming PDF 2.0 specifications and is compatible with Adobe® Acrobat® X, XI and above.

Finally, our PDF viewing components now offer a flexible navigation API, allowing developers to customize navigation within a PDF document or across PDF documents to fit their document workflow.

 “Our goal is to continue to offer the most comprehensive PDF technology available in Java.  We are excited to present our new PDF OCR solution. This is an affordable, integrated solution to recognize text in PDF documents from Java applications on Windows, Mac and Linux, in a J2EE server environment, or on the client side.” says Gerald Holmann, Qoppa Software President.

The new release adds many other improvements and internal fixes.  For more details, please visit the links below:

Spring release of Java PDF libraries adds new PDF editing component, JavaScript, time-stamping of digital signatures

Atlanta, GA April 11 2013 – Qoppa Software’s new spring release of Java PDF components and libraries delivers a new PDF editing and redacting component as well as support for JavaScript and time-stamping of digital signatures.

Qoppa Software is pleased to announce jPDFEditor, its new PDF editing component, which supports all the rendering, annotating and form filling features found in Qoppa’s other PDF components, plus more powerful editing features:

  • Content Editing: the content editing tool allows users to modify the content of  PDF documents:
    • Copy, delete, edit, move text
    • Copy, delete, move, resize images
    • Copy, delete, edit, move, resize shapes, and paths
    • Work with single or multiple text, image, or path objects
  • Redaction:  the redaction feature lets users permanently remove sensitive information from PDF documents:
    • Add redaction annotations to cover an area on a page. The area can contain any PDF objects such as text, image, or shape objects.
    • “Burn” the redaction annotations to remove the underlying content that intersects with the area redacted.
  • Access to jPDFProcess API: jPDFEditor comes packaged with Qoppa’s jPDFProcess library, providing access to a rich API to further manipulate PDF documents programmatically.

“We expect our new PDF component, jPDFEditor, to be of great interest to document management professionals wishing to PDF-enable their DMS, ECM, and BPM systems. Developers and integrators can now deploy a powerful PDF editor in their own java and web applications and be reassured that they have the most advanced Java PDF technology and user interface available on the market.” says Gerald Holmann, Qoppa Software President.

The new release also adds JavaScript support to Qoppa’s Swing PDF rendering components jPDFViewer and jPDFNotes, making it easier to fill interactive forms with features such as:

  • Form field calculations to automatically compute the value of given fields from other fields.
  • Form field validation to prevent invalid data entry and ensure that all required fields are filled in.
  • Form field formatting to facilitate the capture of special fields such as dates, social security numbers, postal codes, phone numbers, etc.

Time-stamping of digital signatures was added to fulfill the needs of Qoppa’s customers as many security standards now require this added level of security to encrypt administrative and legal documents. With the new 2013R1 release, it is possible to apply and verify PDF Digital signatures with Server timestamps authenticated by a trusted, independent authority.  Time stamps are essentially encapsulated in another certificate signed by the authority which contains both the customer’s and the time-stamp server’s signatures.

The new release adds many other improvements and internal fixes.  For more details, please visit the links below:
