Embodiments described herein include a trail generator for implementing a content trail associated with selected data pages. The trail generator retrieves references to data pages selected from the Internet from storage and generates a content trail for the data pages selected from the Internet. The content trail is generated using the references by organizing the references into a user-defined, ordered sequence in the content trail and interconnecting the reference using user-assigned relationships to define at least one path in the content trail that is navigable by a viewer.

Trail-based data content discovery, organization, and processing

What is provided herein is a novel system and method which improves efficiency of a color management system performing a gamut mapping function. In one embodiment, a plurality of source colors are examined to determine whether any have changed. If not, then the source profile, the source device model, and the color appearance model have not changed. Next, the primary colors of the destination device are examined to determine whether any of these have changes. If these have not changed, then the destination device profile and the destination device model have not changed. When the source profile, device profile, color appearance model and the device models have not changed, gamut mapping does not have to be performed. The cached gamut mapping data are used instead. The gamut mapping data are used in subsequent mappings between these same two devices. The cached gamut mapping data are used to customize a color response of the destination device.

Caching for color management systems performing a gamut mapping function

A client-side handheld device requests a server to convert server-side documents into a compression format prior to transmission of said documents to the client. The server retrieves and converts the requested documents to a raster image that is then compressed according to attributes based on information received from the client device in the initial document request. Instead of having to manipulate multiple formats which the original documents are in and supported by the server, the client-side device is preferably optimized in hardware and/or software to support and otherwise take advantage of the requested compression format. The compressed document is then delivered to the client device, in whole or in part, selectively or progressively over time per individual requests prior to displaying the received data to the end-user. Depending on the requested delivery mode, server-side documents are preferably compressed using wavelet compression methods, such as the JPEG 2000 standard, known in the arts. Through such a compression format, documents of sizes (in total bytes) exceeding one or more Megabytes can be compressed down to as small as 30 kilobytes or less.

Method for viewing, on a client-side device, documents requested from a server-side device

Method for document viewing

A document object includes informational elements and at least one attribute corresponding to a first document, and a sub-object corresponding to a second document. The sub-object includes informational elements and at least one attribute corresponding to the second document. Optionally, the second document may be a subset of the first document. Any of the attributes may include elements such as an access right, operation, informational element, internal state indicator and/or work low instruction. The document object is stored in a manner such that when the document object is decompressed, the sub-object remains compressed until it is also decompressed.

Document objects

A system and method for the placement and retrieval of embedded data blocks within a document includes converting a document into a bitmap image; calculating a total area required to embed information; analyzing the bitmap image for areas for placement of at least one embedded data block; calculating a total available area in the bitmap image to embed the information; dividing the information to encode into data packets; determining a location on the bitmap image to place at least one embedded data block; storing coordinate information for the location of the at least one embedded data block; creating a decoding protocol for at least one embedded data block; encoding the data packets and the decoding protocol into at least one embedded data block; and creating a bitmap image of at least one embedded data block.
