摘要: In general, in one aspect, the invention features an apparatus, method, and computer program product for automatically selecting a rendering intent. It includes identifying a device color profile associated with a device; and automatically selecting a rendering intent based on the transform defined by the device color profile. Selecting can include determining a minimum luminance the printing press can produce; and selecting one of a plurality of rendering intents based on a comparison of the minimum luminance to one or more predefined thresholds. Selecting can include selecting a first rendering intent when the difference between a minimum luminance the printing press can produce and a minimum luminance the proofing printer can produce exceeds a predefined value; and selecting a second rendering intent otherwise. Selecting can include selecting a first rendering intent when a color gamut of the printing press is substantially contained within a color gamut of the proofing printer; and selecting a second rendering intent otherwise.

摘要: An apparatus, method and computer program product for transforming data from a source device color space to a destination device color space, wherein the source device is associated with a source device profile and the destination device is associated with a destination device profile. It includes transforming data from the source device color space to an intermediary color space associated with an intermediary color profile using the source device color profile, a source rendering intent, and the intermediary color profile, producing intermediary data; and transforming the intermediary data from the intermediary color space to the destination device color space using the intermediary color profile, a destination rendering intent, and the destination device color profile.

摘要: In general, in one aspect, the invention features an apparatus, method, and computer program product for automatically selecting a rendering intent. A device color profile associated with a device is identified. A rendering intent is automatically selecting based on the device color profile. A rendering intent can be selected based on comparing a color gamut of the output device to a color gamut of the emulation device.

摘要: A technique for compressing a color or gray scale pixel map representing a document. The pixel map is decomposed into a three-plane representation, a reduced-resolution foreground plane, a reduced-resolution background plane, and a high-resolution binary selector plane. The foreground plane contains the color or gray scale information of foreground items such as text. The background plane contains the color or gray scale information for the "background" of the page and the continuous tone pictures that are contained on the page. The selector plane stores information for selecting from either the foreground plane or background plane during decompression. Each of the respective planes is compressed using a compression technique optimal for the corresponding data type. Also described is a method for decompressing documents compressed into the three plane representation at arbitrary resolutions.
