A process is set forth for viewing an enlarged area of an image. The image is stored on a server and re-sized for viewing on a mobile communication device based on screen size and color display capabilities of the device. The image is enlarged within the server by modifying binary raw data of the original image based on crop rectangle coordinates entered at the mobile communication device. The process allows users to quickly retrieve any relevant part of a large image attachment that has been resized by the server. This minimizes bandwidth usage, device memory/CPU consumption, and request/response latency while still allowing the user to view an image area in its original level of detail.

Method for requesting and viewing a zoomed area of detail from an image attachment on a mobile communication device

Systems and methods of retrieving and presenting partial (skipped) document content are provided. A typical system includes a document parsing stage, a device request for content stage and a delivery of requested content stage. A target device can include a device presentation of the requested content stage. The system parses the content of an electronic document and generates a document object model (DOM) representation of the electronic document, where each source and destination target is assigned a document object model identifier (DOM ID). In some instances, upon completion of parsing, the document object model is then paginated in computer memory into segments of a certain size called chunks; in such instances the pagination operation can update each DOM ID with an additional information attribute containing the chunk index with the purpose of establishing a relationship between a document object model identifier and the corresponding chunk index. Thus, when a device requests specific content corresponding to the DOM ID the chunk index value indicates the correct chunk to be returned to the device. The device initiates a document viewing experience by requesting, parsing and displaying an initial chunk of document content as delivered by the corresponding server. The device can, upon parsing the data chunk, record navigational information provided in the form of link information containing corresponding DOM ID and Chunk Index information. The link information can in certain instances be presented visually by a dotted underline.

System and method of retrieving and presenting partial (skipped) document content

A process is set forth for previewing a table attachment on a mobile communication device, and upon identifying table content of interest viewing and/or retrieving the entire table from an attachment server. In one embodiment, a small 4&#xd7;4 row/column preview is presented on the device of every table found in a document attachment, with the cell content textual information limited to the requesting device display capabilities. This limitation avoids any requirement to download large amounts of individual cell content to the device. Thus, the user is able to quickly identify which tables are of interest and then request a full table download from the attachment server in an on-demand fashion. In this regard, the preview table itself preferably also functions as a link to the full table stored at the server to facilitate easy retrieval to the device for viewing in a spreadsheet view.

Method for requesting and viewing a preview of a table attachment on a mobile communication device

A process for viewing a selected portion of a document on a mobile communication device without having to request multiple pages of the document contents containing document global properties applied to the selected part of the document, comprising marking pages of the document within a server, based on size required by the mobile device, associating properties and attributes of the selected portion with the pages, and transmitting the pages with the properties and attributes for display by the mobile device.

Method for document page delivery to a mobile communication device

A process for transmitting a document from a server to a mobile device on a per page basis, comprising building a graph structure within the server representing a map of the document, transmitting a page size limit from the mobile device to the server indicative of the size of a single page of the document to be displayed by the mobile device, traversing and paginating the graph structure into successive pages based on the page size limit, caching the pages within the server, and transmitting the successive pages from the server to said the mobile device for display by said the mobile device.

Method for paginating a document structure of a document for viewing on a mobile communication device

A process is set forth for viewing an enlarged area of an image. The image is stored on a server and re-sized for viewing on a mobile communication device based on screen size and colour display capabilities of the device. The image is enlarged within the server by modifying binary raw data of the original image based on crop rectangle coordinates entered at the mobile communication device. The process allows users to quickly retrieve any relevant part of a large image attachment that has been resized by the server. This minimizes bandwidth usage, device memory/CPU consumption, and request/response latency while still allowing the user to view an image area in its original level of detail.

A server find process by which a user enters a search term for a document attachment into his/her mobile communication device. If no occurrences of the term are found on the device, the device then prompts the user to initiate a server side search. If the user accepts, then the server searches the document attachment and returns the first section of text that contains the search term to the device for viewing by the user. This process can then be repeated until the server find feature reports that no further instances of the search string have been found on the server.
