A method and system for creating color separations comprising discrete computational objects whose edge contours are mutually compatible, such contours being defined based on user-selected n-way color relationships. The objects may be moved, copied, scaled, re-oriented, altered in appearance or resolution, or otherwise manipulated by a user as units. In operation, the invention analyzes a multicolored pixelmap to identify edges associated with regions of a particular color. As it traces an edge the invention generates a secondary edge whose distance from the original edge is determined by the pairwise relationship between the adjacent colors; that distance may vary as the color abutting the edge changes. The pixels along the secondary edge are stored as an order list of pixels that defines the object thus traced.

Method and apparatus for preparing color separations based on n-way

An interface system that facilitates user interaction with a plurality of document-management programs, each of which may require different data formats, and convenient output of data generated by such programs to recording or display devices. The invention includes a 'front end', which accepts user commands and channels them to a designated application program; and a 'back end', which converts output data into a form compatible with a selected output device or display, and which can simultaneously drive display of data from a plurality of application programs. The system operates using a common set of raster-image instructions; output and display data from an application program are converted into this common set of instructions before being provided to a selected output or display device. The system can store multiple display lists in segregated memory partitions, and then combine the lists according to a user-defined 'mapping' procedure to produce a single, integrated display.

Data-handling and display system capable of supporting multiple

An object-oriented document management and production system in which documents are represented as collections of logical components, or 'objects', that may be combined and physically mapped onto a page-by-page layout. Stored objects are organized, accessed and manipulated through a database management system. At a minimum, objects contain basic information-bearing constituents such as text, image, voice or graphics. Objects may also contain further data specifying appearance characteristics, relationships to other objects, and access restrictions.

Document management and production system

A method of adjusting the contours of lineart shapes appearing in bitmap or halftone separations for variations in the mechanical characteristics of printing devices, the color of the separation, and the existence of neighboring lineart shapes. The method involves decomposing the image into discrete lineart shapes, and performing dot-by-dot shifting operations to achieve adjusted shape contours.
