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.
