Qoppa Software’s fall release of Java PDF libraries and components improves PDF text extraction and rendering performance

Java & PDF - Qoppa does it alL!Atlanta – September 12 2012 – Qoppa Software, a leading provider of PDF solutions, releases newly improved versions of all of their Java PDF library products.

Qoppa’s Java PDF class libraries are enhanced with a new powerful algorithm for text extraction.

“The order and organization of text objects in a PDF document do not necessarily correspond to the logical reading order.  We have developed a new text extraction algorithm which detects the natural flow of even structured PDF documents such as research or newspaper articles. We’re very happy with the results when compared with other PDF tools.” says Gerald Holmann, Qoppa President.

The new release also adds enhanced memory management so the PDF libraries can handle rendering and printing of very large CCITT fax images (200Mb and above).

In this fall release, Qoppa’s Java PDF visual components benefit from a new tile-based rendering approach which splits each page of a PDF document into multiple tiles that can be rendered and cached independently. This new strategy enables implementing out of thread rendering and improving image caching and memory usage, which makes it easier to work with intensive PDF documents in 3 areas:

  • Faster rendering
  • Smoother drawing of annotations
  • Better GUI responsiveness

Also new in this release is Qoppa’s pan and zoom tool which will allow users to zoom in and out of high-resolution pages and move around a page (“pan”) while also displaying a larger view of a page.  This new tool should greatly benefit professionals working in the media, print, and graphics industries.

Thanks to the revision of Qoppa’s text extraction algorithm, text selection and highlight is also greatly improved in the visual components.  Now cursor based, it follows the logical reading order of structured documents and allows marking up text across columns.

“The new release brings our Java PDF rendering components to a whole new level, delivering one of the best user experiences available on the market when it comes to viewing, marking up and scrolling through PDF documents.” – Gerald Holmann, Qoppa President

New general release of Java PDF components/libraries adds group annotations & unlimited file size access

Qoppa Software, a leading provider of PDF solutions, announces the general new release of their PDF libraries and components. This new version of Qoppa’s developer products continues the decade long tradition of Qoppa Software delivering tools for integration within web-based and java applications to quickly and reliably add PDF document capabilities such as viewing, printing, signing, form filling, markup and manipulation.

jPDFViewer, Qoppa’s Java component to display PDF documents,
as well as jPDFPrint, Qoppa’s Java library to print PDF documents,
now offer support for unlimited PDF file sizes as well as a faster document loading time.

“These improvements are possible thanks to the implementation of a new PDF source which accesses the PDF content directly from the files instead of having to load the contents into memory.” explains Gerald Holmann, Qoppa Software CEO.

jPDFNotes, Qoppa’s Java component to display, mark up and sign PDF documents, now offers full support for group annotations. Grouped annotations can be copied, moved, deleted, reviewed or flattened at once.

Performance has also been improved in Qoppa’s PDF engine, especially when rendering graphical documents with transparency. Users in the graphics and pre-press industry may enjoy faster processing times, in some cases up to 5 times faster, when printing and displaying such documents.
