Internet Imaging (Web Forms)
LEADTOOLS provides functionality for developing Internet/intranet applications. The .NET Class Library offers methods for loading images from files or streams, which allows images in any supported raster format to be read from any URL. The same functionality is available for loading LEADTOOLS annotation files.
The LEADTOOLS WebForms controls provide functionality to develop rich interactive web-based applications using ASP .NET. Features include:
- A Web ImageViewer control for displaying an image on an ASP.NET 2.0 web form
- The ImageViewer is used to display any image file format supported by web browsers (JPEG, GIF, PNG and BMP).
- Includes an HTTP handler to serve non-browser supported formats.
- Large image support through tiling.
- Includes an HTTP handler to get file information for files on the server or accessible via http.
- The ImageViewer control can automatically handle zooming and scrolling.
- Create Web applications that deal with huge images such as Geospatial imaging applications like Google™ Earth. Only the portions of the image required for display are downloaded and compressed.
LEADTOOLS includes support for Progressive JPEG, Progressive CMP, and interlaced GIF, so you can display images as they are downloaded. GIF support also includes transparency, animation, and embedded text. The GIF code has support for 1 through 8 bits per pixel files. A FeedLoad function is included to allow image data to be displayed as it is being transmitted across the net, providing Internet programmers with the fastest way to begin painting the client’s screen. This functionality is included in the LEADTOOLS Raster Imaging Pro, Document Imaging products and Medical Imaging products. Additionally, HTTP and FTP libraries are included to help you send information and images from the client back to the server. An INET command library is included to create client server applications to control remote computers using remote procedure calls. Examples are included to assist you in incorporating images into Internet applications.
