Qoppa Software is pleased to announce a new PDF OCR solution for Java 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, their 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.
Qoppa Software specializes in Java PDF library products – pure Java as well as Android Java – for developers to integrate into their own Java or web applications. Qoppa Software also offers a fully-featured PDF end-user application, a PDF server, andAndroid PDF apps developed on Qoppa’s own robust PDF technology.
