Qoppa Software (http://www.qoppa.com), a provider of PDF solutions, has released ew versions of its Java PDF Libraries and Components, adding PDF feature coverage along with improvements in memory management and performance.

There's now new Unicode support in jPDFProcess, jPDFAssemble, and jPDFNotes. These libraries now allow editing unicode text in annotations content and within document properties (author, subject, description). This will be of special interest to customers using non-latin characters such as Arabic, Asian (Chinese, Japanese and Korean), Greek, or Cyrillic characters.

There's new callout annotation in jPDFProcess, jPDFViewer, jPDFNotes. The callout tool combines a text box with a line and an arrow and is used to draw attention to text or objects in a PDF document.

Theres a new calibration tool in jPDFNotes. The measuring tool now also allows architects and engineers to set the scale directly on the drawing.

Enhanced digital signatures in jPDFProcess and jPDFSecure allow developers to customize digital signatures by adding custom appearances (for instance adding image and text).
