Vancouver Island-based Corporate Smalltalk Consulting Ltd  has announced the release of PDF 1.8.7 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 $3.99 USD app employs proprietary LargeViewer technology to pre-render large or complex documents for smooth scrolling and zooming.
In addition to managing PDF files of thousands of pages, PDF 1.8.7 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.
* 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
* iOS 5.0 ready
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. 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 documents happens instantly, no opening lag times.
“PDF documents have become ubiquitous in business, manufacturing, and consumer life” stated Corporate Smalltalk Consulting President, John McIntosh. “Now, with PDF 1.8.7, 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.”
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 transferred to your ISO device for further reading.
PDF 1.8.7 is compatible with iPhone, iPad and iPod Touch devices running iOS 4.0 or later.
