Abstract: An image processing apparatus, program product, and method determine an achievable gamut achievable by the imaging engine or engines for all spatial locations of an output image, or all utilized print engines. A reference gamut is calculated which is any gamut containing the achievable gamut. A gamut mapping is used to map gamuts from the mean gamut to the achievable gamut, and a set of transformations is calculated for each of a set of input colors to a set of target colors selected from colors in the achievable gamut. Values for a received digital image are transformed for each image pixel or clusters of pixels based on the calculated set of transformations. Output images are generated based on the transformed values.

Abstract: What is disclosed is a novel apparatus and method for effectuating the ordering of supplies via a wireless handset device. In one embodiment, the handset is pre-loaded with a plurality of folders each representing a multifunction device. A user navigates the hierarchy of folders and selects a folder.

The profile contains the ordering method and contact information. An order message is prepared according to the ordering method prescribed by the profile and is sent to the supplier to place an order for that supply commodity. The process repeats until no more supplies are to be ordered. Additional features, enhancements, and embodiments have been provided.

Abstract: Disclosed are embodiments that use multiple, belt-steering systems to control and maintain alignment of an endless belt. The position of the edge of the belt is measured by multiple belt edge sensors and then corrected by at least two steering rollers connected to corresponding steering mechanisms. The steering mechanisms tilt the rollers in order to selectively adjust the lateral position of the belt. Steering can be controlled independently with the tilt of each steering roller being adjusted based solely on information obtain from a corresponding belt edge sensor. Alternatively, steering can be controlled dependently with the tilt of each steering roller being adjusted based on information obtain from multiple sensors at multiple locations and further based on the predictable impact of the simultaneous movement of both rollers on belt positioning. In addition, at least one of the steering rollers can also be configured as a drive roller.

Abstract: Extended colorant sets are used to hide data or provide a watermark in printed images. Extended set colorants are colorants other than, and in addition to, the standard or common subtractive primary colorants: cyan, magenta, yellow and/or black. Where the extended colorant set supports a plurality of colorant recipes for rendering a given color, watermark data is used to select a colorant recipe from the plurality. As the watermark data to be encoded in the image changes state with image position, alternate colorant recipes or colorant selection functions are selected. The image is rendered based on the alternate colorant recipe selections. Watermark information is encoded in the colorant recipe or colorant selection function selection. Use of the extended colorant sets allows information to be encoded even in portions of an image having colors that do not include a neutral component.

Abstract: A client-side handheld device requests a server to convert server-side documents into a compression format prior to transmission of said documents to the client. The server retrieves and converts the requested documents to a raster image that is then compressed according to attributes based on information received from the client device in the initial document request. Instead of having to manipulate multiple formats which the original documents are in and supported by the server, the client-side device is preferably optimized in hardware and/or software to support and otherwise take advantage of the requested compression format. The compressed document is then delivered to the client device, in whole or in part, selectively or progressively over time per individual requests prior to displaying the received data to the end-user. Depending on the requested delivery mode, server-side documents are preferably compressed using wavelet compression methods, such as the JPEG 2000 standard, known in the arts.
