October 17 2014. It’s only been 4 months (to the day!) since the previous release but the new version still adds quite a few refinements and fixes to Qoppa’s PDF parsing and rendering engine and to the following features: annotations, form fields, digital signatures and linearization.
New Library: We have released our new PDF optimizer library, jPDFOptimizer, check it out!
Version number: 2014R2 (v2104R2)
Qoppa’s PDF engine API changes from previous version:
New! The API change now also includes the difference in each individual library package: com.qoppa.pdfAssemble, com.qoppa.pdfFields, com.qoppa.pdfImages, com.qoppa.com.pdfPrint, com.qoppa.pdfSecure, com.qoppa.pdfText so library customers can immediately identify the changes in the individual library they use.
