    摘要: 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.

    摘要: The management of color presented at end point devices such as a display or printer is based on the implementation of a Color Management Resource (herein also CMR). A CMR is an architected resource stored accessibly to a print server or other processor that is used to carry all of the color management information required to render a print file, document, page, or data object. The invention here described is particularly focused on a color conversion type of CMR and defines a new type here called a Link Color Conversion CMR. In particular, a unique descriptor is tied to each input and output color conversion rule. A linked color conversion rule, created by combining the input and output color conversion, is created. The linked color conversion structure contains three parts—the descriptor of the input color conversion rule, the descriptor of the output color conversion rule, and the combined color conversion rule. By comparing the descriptors, it is possible to very rapidly identify a previously-existing linked color conversion that combines the input and output conversions.

    摘要: Methods and systems for rendering code points on a presentation device with layout processing performed outside the presentation device. In one aspect, a layout processor translates one or more code points into a sequence of one or more glyph indices and corresponding positioning information. The glyph indices and corresponding positioning information may be included within a PTOCA control sequence. The glyph indices may be used by the presentation device to directly locate a corresponding glyph image in a font. The positioning information defines positioning of each glyph image so identified. Features and aspects hereof allow efficient layout of complex text in which glyph images and positioning may be dynamically determined in accordance with context or other attributes. The processing burden of such layout processing is removed from the presentation device without significantly increasing data transmission bandwidth between the presentation engine and external system utilizing the layout processor.

    摘要: A method, computer program product and system for managing font resources using system independent references. A resource library may store a table, referred to herein as the “resource access table” that contains an entry for each base font resource. Each entry may include the following information on a base font resource: a native name, a file name, a unique identification, attributes, and possibly a link list used to identify any font resources that are linked to the base font resource. Since changes to the resource file such as updating a version of a font resource, changing the attributes of the font resource or changing the font resource's linked fonts, simply require an update to the resource access table, the data stream and the application program generating that data stream does not have to be changed.

    摘要: A method, computer program product and system for switching fonts without embedding font switching commands in the data stream (logical description of the print document) between a client and a print server. The client in a printing system may receive a character where the character is a modified character in a base font resource or is a character to be added to or deleted from the base font resource. The client may create a font resource that includes the received character. The client may further link the created font resource with the base font resource or vice-versa thereby allowing a user to use both the characters in the base font resource and in the linked font resource as if they were a single font resource without building or buying a special purpose font resource. Consequently, font switching commands are no longer necessary to be embedded in the data stream.

    摘要: Systems and methods are provided for indexing in Advanced Function Presentation (AFP) systems. One embodiment is a system that includes a memory and a controller. The memory may store Advanced Function Presentation (AFP) print data. The controller may load the AFP print data, detect an AFP Object Container Data (OCD) structured field within the print data, and follow a pointer from within the OCD structured field to a global reference. The controller may also acquire Metadata Object Content Architecture (MOCA) header information within the global reference, and process the OCD structured field based on the MOCA header information within the global reference.
