Appl. No.:

10/941763

Inventors:

Olav A. Sylthe - Atlanta GA, US

Dan Dumitru - Atlanta GA, US

Assignee:

Research In Motion Limited - Waterloo, Ontario

International Classification:

G06F 3/00

US Classification:

715800, 715798, 715799, 715801

Abstract:

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.

Abstract:

A method for viewing a full image of a server stored original attachment on a portable electronic device including: building a graph structure within the server representing a map of the original image, downloading and displaying a re-sized image from the server to the portable electronic device, the original image exceeding an image size limit of the portable electronic device indicative of screen size of the portable electronic device, calculating width and height parameters of the full image, sending a request from the portable electronic device to the server to enlarge the image displayed on the device based on the width and height parameters, the request including the image size limit, retrieving and traversing the graph structure within the server to locate a separate image component constructed for the image size limit, collecting image binary data from the separate image component and modifying the image binary data based on the width and height parameters to create the full image of the original image and downloading the full image of the original image to the portable electronic device.

US Classification:

709206, 715746

Abstract:

A method for viewing an attachment of an email message on a portable electronic device in which the attachment has a renderable format is provided. The method includes: requesting to view the attachment in an attachment viewer of the portable electronic device, building a graph structure within an attachment server representing a map of the attachment, the graph structure including at least one renderable identifier corresponding to a page of the attachment, requesting rendering of the attachment, the rendering request being send from the attachment viewer to the attachment server and including the at least one renderable identifier, initializing a rendering library and storing rendering commands corresponding to command types of the graph structure in the rendering library, drawing the rendering commands in an off-screen bitmap, saving the off-screen bitmap as a JPEG file, sending the JPEG file to the portable electronic device and displaying the JPEG file in the attachment viewer.

International Classification:

G06F 17/00

US Classification:

715212, 715218

Abstract:

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 4×4 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.

International Classification:

US Classification:

707770

Abstract:

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.
