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)

Java PDF Libraries: jPDFProcess, jPDFAssemble, jPDFFields, jPDFImages, jPDFPrint, jPDFSecure, jPDFText

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.
API Changes

Parsing / Rendering / Printing

[JPDF-450] – Implement convertSamplesToXX methods in CalRGB and CalGray color spaces
[JPDF-77] – New IPDFDocument.getDocViewPrefs() to get and set viewer preferences entries in the root catalog
[JPDF-82] – Improved support for underline in PDFGraphics
[PS-1656] – Document Specific: Upside down text in attached document
[JPDF-437] – Document Specific: Exception parsing content stream: com.qoppa.pdf.PDFException: Unrecognized command: +0.000
[PS-2230] – Document Specific: NullPointerException on getClipBounds Exception when printing document.
[JPDF-104] – Better support for start and end subroutine entries for Type1 fonts
[JPDF-435] – Document Specific: When exporting a page as an image, an image is rendered at the wrong location due to a graphics composite
[JPDF-444] – Document Specific: Issue with misplaced drop shadow when converting PDF to image due a soft mask

[JPDF-295] – Save custom rubber stamps appearance streams when exporting annotations to XFDF
[JPDF-54] – When creating image stamps or push button with images, PDFImageStream (image, params) will use jpeg compression instead of flate when params is null

[PS-1556] – Document Specific: fail to render due to PDFGlyphVector throwing runtime exception
[JPDF-467] – Document Specific: Delete annotations and save, page content disappears due to stream objects

Form Fields
[JPDF-331] – For fields missing appearance stream, only modify the appearance stream dictionary when NeedAppearances is true or when the field value has changed

[PS-2349] – In form calculation, fields with container were not always computed properly

Digital Signatures
[JPDF-426] – QSignature.clearSignature() was always returning false. It now returns true if it completes successfully.
