LEADTOOLS Version 18, also known as LEADTOOLS Anywhere™, provides the most comprehensive and highest quality imaging SDK technology on the widest variety of development platforms including WinRT, Windows Phone, HTML5, iOS, OS X, Android and Linux. Viewers, annotations and markups, barcode, OCR, PDF, image formats, compression, image processing and more are just a sampling of what LEADTOOLS has to offer any developer, not just those targeting Windows.
Programmers using LEADTOOLS can experience a set of libraries that closely resemble each other on every development platform. This is a distinct advantage for developers whose goal is to create native versions of their apps on multiple platforms. Even if your plan is to develop for a single platform, LEADTOOLS provides a programmer friendly interface for every major platform out there, giving developers the flexibility and peace of mind to easily expand in the future.
In the examples that follow, we’ll show how to convert a platform-native image into a LEADTOOLS RasterImage, and then use the Barcode engine to get its symbology (i.e. UPC/EAN, Code 128, QR Code, Data Matrix, etc.), location and encoded value. Alternatively, developers can use the RasterCodecs object to load and save their images. However, using LEAD’s conversion utilities is a powerful asset for existing applications because it requires minimal changes to your current code base.
