Qoppa Software’s release of Java PDF libraries & components improves PDF text extract & rendering
Qoppa Software’s fall release adds multi-column text extraction in all Java PDF libraries, plus threaded rendering and new pan & zoom tool in GUI components.
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.” - Gerald Holmann, Qoppa President.
The new release also enhances 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 zoom in and out of high-resolution pages and move around a page (“pan”) while also displaying a larger view of the page.
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.
