摘要:
An image processing system for sequentially executing processes includes a process execution control apparatus to control an execution of the processes, and an image generation-output control apparatus to control an execution of image generation-output operation. The process execution control apparatus includes a control-side drawing information generator to generate drawing information to be referred when an image forming apparatus performs the image generation-output operation. The image generation-output control apparatus includes an output-side drawing information generator corresponding to the control-side drawing information generator. The control-side drawing information generator excludes an execution result of a designated process item from execution results of a plurality of process items, to be executed for generating the drawing information, to generate designated-information-excluded image information. When process contents of the designated process item is set at the image generation-output control apparatus, the output-side drawing information generator executes the plurality of process items based on the designated-information-excluded image information.

A method and system for rendering rectangle drawing objects are provided. For at least a first rectangle drawing object and a second rectangle drawing object, a determination is made if the second rectangle drawing object satisfies a predetermined condition with respect to the first rectangle drawing object. If the predetermined condition is satisfied, one-line raster image data associated with the second rectangle drawing object is generated and stored in a data buffer. The one-line raster image data indicates a filling color of the second rectangle drawing object over a first extent in a first direction. Subsequently, the one-line raster image data may be used a number of times over a second extent in a second direction perpendicular to the first direction to fill a drawing region corresponding to at least the second rectangle drawing object.
摘要:
A method and apparatus for Variable Data Printing that adds performance requirements to a raster image processor (RIP) memory optimization that employs memory bands within the page composition process. Documents containing both recurring elements as well as non-recurring elements are sorted into element lists depending on their frequency of recurrence and their layering position. The recurring elements are retained in rasterized form, while the non-recurring elements are rasterized as they are used in output memory. One pass assembly in raster image processing of the elements occurs when the recurring elements are blitted into memory and the variable elements are RIPped on the fly.

摘要:
A method and apparatus for addressing the problem of combining a plurality of Page Description Language (PDL) separation color files to create a display list of objects that represents the composite or combined output image as described by the PDL separation files. Furthermore, any conflicts about the z-order of the display list is resolved by correctly ordering the objects in the display list to the extent that the ordering is significant. The need to produce a display list of objects that represents the composite or combined output image arises from digital preproofing, a technique of proofing and editing the output color image for production from images obtained from a proofing device other than the actual production printer.

In order to select an interlace printing method, first, a resolution for a video print process is specified. Next, the actual amount of the free space in the shared area 33b of the RAM is detected. Then, the printing methods available are detected from Table 1. The printing method that uses the greatest number of ink jet nozzles is selected from the printing methods detected. Then, the video printing operation is executed using the selected printing method.

A method of automatically optimizing the controllable parameters related to producing printed material on a hardcopy output device is provided, along with a hardcopy output device configured for implementing this method. Users require different types of printed objects to have different characteristics. Specifically, business graphics need to be sharp and vivid, photographic images should look realistic, and text must be black, crisp and clear. By extracting, analyzing and conditioning data generated during a printing stream, the various regions of text, graphics and photographic images on a sheet are distinguished, characterized, and printed. The resulting hardcopy output has a custom balancing of color which is pleasing to the human eye for each type of image printed, and which has print characteristics tailored for the specific elements on the page.
摘要:
An integrated graphics manipulation program that employs a technique of rasterizing EPS files during import and using this rasterized version as a "proxy image" for display of an on-screen image. When a document containing a EPS data is printed to a PS printer, the actual EPS data is sent to the printer. If the document is printed to a non-PS printer, the rasterized proxy representation of the EPS data is used. The effect that this has is that the on-screen representation of the EPS data (the rasterized proxy image) is a high quality representation of the EPS data. The original EPS data may be re-rasterized at a new scale to generate a new proxy image whenever a user resizes the proxy image on the display. This results in an on-screen representation that more closely resembles the printed output to a PS printer. The EPS data also may be re-rasterized at a new scale to generate a new proxy image whenever a user zooms in to or out of a document. This would give the desired effect of reducing aliasing that occurs when a static rasterized image is zoomed. With this approach, the EPS proxy image becomes a dynamic on-screen representation of the original EPS data. The preferred "native" file format for any program implementing the invention remains vector-based, so that the highest quality image is always available regardless of printer type.

A VLSIC page printer controller includes an instruction processor which responds to a host computer and a printer video processor for accessing data from memory under the control of the instruction processor and serializing data for transfer to a printer through a video port. An I/0 interface interconnects the printer controller with an I/O bus to which is connected a host computer, memory devices, and other peripheral devices. An internal memory interface connects the printer controller to memory, and the printer video processor is provided with direct memory access (DMA). Data and instruction caches and an instruction ROM are provided on-chip. A RISC instruction processing unit includes as an integral part thereof the special function circuits of orthogonal rotator, bit/byte mirror, and pixel modification.
