System and method for transferring a compressed data file to a peripheral device

摘要: An image passthrough extension structure and method facilitating the transfer of compressed data files from a software application to device via computer system operating system. The determines whether is capable decoding specific file by polling driver. If driver returns “no support” message, processes in conventional manner. “support” transfers file, along with additional processing information, utilizing structures modified incorporate function. By allowing an directly driver, present invention improves fidelity overall efficiency reducing size transferred between application, hardware device.
