Document Type and Number:
Japanese Patent JPH0613212
Kind Code:
B2
Abstract:
The outline of a character which is developed on X and Y coordinates is split into a number of blocks (P1, Pn) (where P1 and Pn are a start point and an end point of an arbitrary block respectively) each defined by a univalent function involving X as a variable. Block data are produced to specify the shape of each block, of which data is stored as the compressed data of one character to accomplish compression of the data. A memory is provided for storing the start point coordinates of a straight portion, and the start point coordinates of each sampling segment established on a curved portion, and the coefficient and the degree of the cubic polynomial which approximates each segment.
