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.
摘要:
A handheld electronic device useful for wireless communication has a keyboard including a plurality of externally accessible keys, of which at least a portion have multiple letters associated therewith. The keys can be disabled (i.e. the keyboard can be locked) to prevent accidental actuation thereof by using the navigation tool which has a depressible rolling member. Thus, for example, depression of the rolling member twice in succession or pressing and holding the rolling member down temporarily enables the keyboard lock. The lock can be disabled simply by depressing the rolling member and at least one other key.
