Leadtools.Jpip Introduction

Summary

The LEADTOOLS JPIP (JPEG 2000 Interactive Protocol) assembly supports interactive streaming of large images and associated image data using the minimum possible bandwidth. It is especially well-suited to using internet connections for viewing and manipulating large medical, geospatial, and very-high-resolution camera images stored on remote servers. It is an implementation of the JPEG2000, part 9 standard (ISO/IEC 15444-9), including both meta-data and code-stream elements.

LEADTOOLS JPIP client/server architecture allows very large, compressed JPEG2000 images to be stored on a server. In addition, the client can specify the image resolution for a transmission, as well as quality and region of interest (ROI) attributes. This allows client applications to interact with a stored image without transmitting the entire image, or decoding the entire image code-stream. The server and client components include a number of options for controlling this image streaming and decoding.

The LEADTOOLS JPIP assembly comprises high level components that developers can easily plug into enterprise client/server applications, making it possible to immediately start streaming high-resolution images under low HTTP bandwidth connections.

Key Features:

Allows fast, flexible code updates: LEAD's managed code does not depend on third-party libraries.
Optimizes network efficiency through progressive image transmission, without sending redundant data.
Provides fast image viewing through progressive decoding of images resolutions, tiles, and components.
Supports browsing lossless high-resolution medical and geospatial images.
Supports JPEG2000 code-streams and multiple file formats (J2K, JP2 and JPX).
Supports streaming over HTTP V1.1 transport protocol

Server Component:

Gives fine control over allocated server bandwidth, total server bandwidth, client connections bandwidth, and chunk size.
Enables conservation of server resources through setting the maximum number of client connections, client lifetime, and timeouts.
Enables performance enhancement through splitting the streaming process among multiple servers running on different machines.
Supports interactive client requests and server response handling.

Client Component:

Decodes low image resolutions and progressively decodes higher resolutions on user request.
Decodes user-requested regions of interest (ROI), component, and quality.
Enables local caching of images information for faster future viewing.
Controls the amount of data delivered in each request.
