Abstract
A method for transmitting image data to a presentation device, such as a printer. The image data is first divided into layers. Each layer is then further divided into tiles. During the rasterization process, tiles, that are repeated within the image are provided a reference identification (ID). During the transmission of the image to the presentation device, a data transmission utility is utilized to determine the most efficient manner to transmit the image tiles and present the image to the presentation device. Resource tiles only have to be downloaded once and every subsequent time the tile appears within an image, only the subsequent tile position and reference ID of the resource are sent, in lieu of the entire tile data being transmitted to the device. The data transmission utility determines which of a number of transmission processes to utilize to transmit the image data, including the speed of the presentation device, available transmission bandwidth, transmission speed of each tile (or relative size of each tile), and size of the image.
