OCR SDK is a fast and robust Optical Character Recognition SDK that can be embedded into your .net application. It can accurately OCR documents in different languages, and convert them to searchable PDF/text.

• 32-bit and 64-bit OCR binaries
• Convert OCR output to searchable PDF files or text
• Support broad types of languages including Asian and Arabic
• OCR hand-written files
• Keep the original image/document layout and fonts
• Support multithread processing and run OCR in high performance
• Detect and retrieve the font, color, size of text
• Recognize files with mixed image and text
• Text over image technology supports high image compression and reduces the size of PDF files.

Dynamic Webcam is a .NET component which enables you to acquire an image from a webcam, edit and then upload to a database or web server. Also, you can capture a live video stream into a container and grab a snapshot and export it to a file/binary. The webcam SDK is based on Microsoft .NET Framework 2.0. It is optimized for use in C# and VB .NET and offers support for WinForms and WPF desktop applications. Dynamic Webcam is based on the DirectShow API and works with all UVC compatible webcams. Windows XP SP2 and later have USB video device class (UVC) support built in, which allows for interconnectivity of webcams to computers without the need for proprietary device drivers.

Dynamic Annotation allows adding annotation capabilities to your .NET applications, so that you can markup and draw objects onto a PDF document, such as underlining or highlighting, notes/comments, circles, and etc. And these visible metadata superimposed do not change the underlying master PDF image. Supported objects include text, rectangle, line and eclipse. You can add one or more annotations to each page, and all annotations can be independently resized, moved, rotated, and placed on different layers. You can also select multi annotations as a group.

Dynamic Barcode Reader SDK is a 1D/2D barcode detection and decoding library which reads multi-format barcode symbols in your .NET applications. It supports recognition of dozens of different barcode types and sub-types. With the high-level and programmer friendly .NET interface, you can add comprehensive brooding with several lines of code, such as

• Configure options to read only barcodes of a certain type, orientation, region of interest and more
• Read multiple barcodes in one image then return the string value of each barcode recognized
• Detect barcodes at any orientation and rotation angle
• Detect the type of barcode recognized
• Images can come from any source including file, memory, Internet, and SharePoint.

Barcode SDK is available as .NET classes, C DLL, C++ classes, WCF services and WF activities.It comes as managed 32 and 64 bit binaries.
