Accelerated Viewing For Complex PDF Documents

Corporate Smalltalk Consulting has announced the release of PDF 1.7.4 for iOS, an update to their universal document viewer app that allows the user to view complex oversize and large multi-page PDF documents easily. The app employs proprietary LargeViewer technology to convert and pre-render large or complex documents for smooth scrolling and zooming.

In addition to managing PDF files of thousands of pages, PDF 1.7.4 can easily handle page sizes as large as 48 x 42 inches. The app includes Dropbox download only connectivity, and can open PDFs found in Mail or Safari, or transferred from iTunes file sharing. Developed specifically to prevent slow-downs and stalls when viewing large PDF files on an iOS device, it has the fastest rendering engine available giving sub-second rendering where other PDF viewers take as long as 8.4 seconds to render the same complex page.

Feature Highlights:
* Accelerated, multi-page PDF file reading
* Pre-rendering allows smooth scrolling and display
* Dropbox file download compatibility
* Responsive sub-second scrolling and zooming through large documents
* Internal and External bookmarking
* Tap to page turn
* Rotation & cropping by document or by page


Operation of PDF is simple on all iOS devices, irrespective of screen size or built-in memory. The user may open standard, single-page PDF documents automatically. Multi-page and oversize documents require a one time pre-rendering, wait for the screen to turn green, and then touch the Viewer button. Pre-rendering times vary according to the size of the document and the iOS device, but the process need be done only once. Having been pre-rendered, the document is permanently stored in its pre-rendered form. Even with oversize documents up to or exceeding 48 x 42 inches, there is continuous, smooth scrolling with no tiling effects, no lags, no stutter. Opening thousand page textbox happens instantly, no opening lag times.

A companion product LargeViewer Helper for IOS PreRendering is an OS-X app that allows you to pre-render many PDF documents such as from archive.org that because of proprietary graphics compression are normally unreadable on an iOS device, yet are readable on OS-X. Once pre-rendered on OS-X those documents can be transfer to your ISO device for further reading and enjoyment via our PDF product.

"PDF documents have become ubiquitous in business, manufacturing, and consumer life" stated Corporate Smalltalk Consulting President, John McIntosh. "Now, with PDF 1.7.4, owners of iOS devices can smoothly display PDF documents of any size or complexity; scroll horizontally or vertically, and zoom in and out with no waiting for drawing to occur, and with our companion OS-X product have the ability to view documents that in the past were un-viewable on IOS."

PDF 1.7.4 is $3.99 (USD) and available worldwide exclusively through the App Store in the Productivity category. Review copies are available upon request.
