LEADTOOLS Changes from Version 17 to Version 17.5

LEADTOOLS V17.5 includes the new LEADTOOLS WinRT SDK. The LEADTOOLS WinRT SDK contains everything a developer needs to create imaging-enabled Windows Store applications. With the toolkit, developers can load, convert and save to and from more than 100 image formats, and use more than 200 advanced image processing functions.

LEADTOOLS V17.5 includes the new LEADTOOLS Cloud SDK. The LEADTOOLS Cloud SDK is a framework for creating "cloud" applications. Cloud applications perform distributed processing of tasks over a network. The server portion of the framework handles the submission, queuing and identification of tasks that are to be performed by one or more separate worker machines. Each worker machine polls the server and then is assigned a job to perform. When the work is completed, the worker machine notifies the server and the queue is updated. The LEADTOOLS Cloud SDK comes with two demo implementations, one for converting raster images to PDF documents using OCR and one for transcoding multimedia files.

LEADTOOLS V17.5 includes new SharePoint integration capabilities. LEADTOOLS SharePoint integrates with other LEADTOOLS features such as OCR, Barcode, File Format Conversion and allows images to be loaded and saved directly in SharePoint. Additionally, it supports SharePoint lists and features Live capture and improved speed for Windows 7 Barcode libraries.
