Abstract

There is provided a system for editing image data in which addition to and correction of image data constructed by a set of dot data can be effected in an extremely simple operation while attaining the matching between the parameters such as the width of a line, the radius, the inclination, and the size of characters of the added or corrected portion and those of the image data. A connected area included in the image data is stored in a connected area data buffer. When a desired point of the image data is specified, a diagram constituent parameter deriving section extracts a connected area adjacent to the specified point from the connected area data buffer and derives diagram constituent parameters such as the width of a line, the inclination, the radius of a circle, the central point, the size of a character string and the character pitch for the connected area. The parameters can be used when the edition is effected by an edition processing section.
