Abstract: A print document conversion apparatus includes a plurality of software-based conversion units and a controller. The plurality of software-based conversion units perform a software-based conversion process for converting print document data described in a page description language into page image data having a bitmap image format. Each of the plurality of software-based conversion units requests a hardware-based image processing apparatus that executes specific image processing in the software-based conversion process to execute the specific image processing, and generates the page image data including a result of the image processing executed by the hardware-based image processing apparatus in response to the request.

Abstract: A print document conversion apparatus includes plural software-based conversion units and a controller. The plural software-based conversion units perform a software-based conversion process for converting print document data described in a page description language into page image data having a bitmap image format. Each of the software-based conversion units requests a hardware-based image processing apparatus to execute specific image processing in the software-based conversion process, and generates the page image data including a result of the image processing in response to the request. The controller activates an additional software-based conversion unit that performs the software-based conversion process when there is a possibility that a state where at least one of the software-based conversion units waits for the hardware-based image processing apparatus to complete the image processing occurs.

Abstract: A print-document conversion apparatus includes a conversion-module activation section that activates, as a process, a conversion module for performing conversion processing for converting print-document data which is described in a page description language and which includes units of processing into print-image data. The conversion module includes a thread activation part, an assigning part, and a shared cache. The thread activation part activates conversion processing threads. The assigning part assigns the units of processing to the conversion processing threads, and causes the conversion processing threads to perform processing on the units of processing. The shared cache is shared by the conversion processing threads. When a conversion result obtained by converting an object included in the units of processing is stored in the shared cache, each of the conversion processing threads obtains the stored conversion result instead of obtaining the conversion result by converting the object.

Abstract: A sender device 1 stores, in header information about image information, information indicating that attribute information and image data rearranged in sequence, and produces image information by means of storing attribute information and image data in a predetermined sequence. The thus-produced image information is sent to a receiver device 2 by way of a network line 3. When receipt of image information is initiated, the receiver device 2 refers to the header information, thereby determining presence/absence, in the header information, of information indicating that attribute information and image data are stored in a predetermined sequence. When it has been determined that attribute information and image data are arranged in a predetermined sequence, image data included in the received image information are immediately decompressed, and the thus-decompressed image data are output in the form of a record or display.
