First Claim
Patent Images
1. A process for viewing a selected portion of a server stored document on a mobile device, comprising:
- building a graph structure within said server representing a map of said document;
marking pages of the document within said server based on size required by said mobile device, wherein said marking pages further comprises transmitting a page size limit from said mobile device to said server indicative of the size of a single page of said document to be displayed by said mobile device, traversing and paginating said graph structure into successive pages within said server based on said page size limit, and caching said pages within said server;
associating properties and attributes of said selected portion with ones of said pages containing said selected portion; and
transmitting said ones of said pages containing said selected portion with said properties and attributes for display by said mobile device independently of other pages of said document;
wherein said associating properties and attributes further comprises searching said graph structure for a node representing a page start for said selected portion of said document;
traversing said graph structure and recursively storing each parent of said node representing the page start in a parent container within said server, such that said parent container contains all nodes and leaves belonging to said page start and each parent of said node;
generating an output for each said page start containing contents and attributes of all said nodes and leaves belonging to said page start and attributes of each parent of said node representing the page start, for transmission to said mobile devices; and
calculating a document ID based on contents of said document before building said graph structure, checking a memory cache of said server using said document ID for said graph having been previously built, and in the event said graph structure exists in the memory cache then omitting the building of said graph structure.
