There is disclosed an image processing apparatus capable of forming white patterns on black background, hatched patterns, patterns with shadows, etc., in a simple manner. The apparatus has plural memories, which are used for defining mutually corresponding dots. These dots are subjected to logic processing, and the obtained dot patterns are released in combination.

Image processing system

A pattern conversion method and apparatus including a storage unit for storing data representative of the contour of a pattern, a readout unit for reading the data from the storing unit; and a processing unit for processing the data read from the storage unit and representative of the contour of the pattern, wherein the processing by the processing unit comprises the steps of: parallel moving each of a plurality of segments constituting the contour of the pattern by the same distance d; solving for an intersection between the moved segments; and repeating the steps for the entire contour of the pattern.

Method and system of converting delineative pattern

A document processing system which makes document files while displaying the inputted document (such as characters, figures, symbols, etc.) has a display section to display the files of the documents which are divided on a page unit basis; an instructing device to prompt a predetermined display so that the printing position when each page of the files was printed can be determined; and a controller for controlling the display section so as to display the files of at least two continuous pages on one screen due to the display instruction of the instructing device such that the state after the files were printed and bound can be known. With this system, a document of continuous pages can be very easily edited on the same display screen while preliminarily checking the printing and binding format.
