Abstract

PURPOSE:To calculate a character pattern of desired magnification without increasing storage capacity by calculating coordinate points according to an inclination equation added to each coordinate point of contour data of the character pattern and the magnification. CONSTITUTION:A one-character-data read part 2 reads contour line coordinates (X1,Y1) - (X3,Y3) of a specified character pattern of one magnification, an inclina tion equation y=ax+b added to each coordinate point, etc., out of a character pattern data storage part 1 according to a specified code and an arithmetic part 3 calculates and determines character pattern coordinates of desired reduc tion, etc., and supplies them to a painting-out part 5, etc. Therefore, respective various-magnification patterns need not be stored and character patterns of desired magnification can be calculated and formed without increasing the storage capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing system, and particularly to a character pattern generating device in a dot printing device in a word processor, printing system, etc. that prints on paper. [Prior Art] Conventionally, when creating a document using a word processor, printing system, etc. that prints on paper, the size of the printed characters is often changed depending on the purpose and output to a dot printing device. In order to change the character size, the system stores character pattern data generated for each character size, and then outputs characters of the specified size. However, this method requires a large storage capacity to format documents using a wide variety of characters of different sizes. Therefore, in recent years, as shown in Figure 3, a method has been developed in which character outline data is represented by coordinate points, stored as character pattern data, and a character of a specified size is output by calculation for a specified character size. The outline character data method (hereinafter referred to as the outline character data method) has been developed.

[Problem to be solved by the invention]

According to the conventional outline character data method described above, arbitrary character sizes can be obtained without deteriorating the character quality, but from the perspective of character designers, the problems shown in Figures 4(a) and (b) As shown in the figure, it is customary to change the design of small and large characters to improve aesthetics and readability, and enlarging or reducing a single character data may not be satisfactory.

In response to this request, conventionally, a certain range has been set, such as text size from 8 points to 12 points, subheading text from 12 points to 30 points, and heading text from 30 points to 50 points. The method used is to store multiple character data that matches the font size to be used and to switch and output the data according to the specified size, but when storing multiple character data, the storage capacity, font, and font consistency are Therefore, it is an object of the present invention to provide a character pattern generating device that can solve these problems.

[Means to solve the problem]

The character pattern generator of the present invention generates a thick, solid character design designed for large characters, and a design for small characters with wide line spacing and emphasis on readability, excluding decorative parts, using the same character pattern data. By locating which part of the two character pattern data each coordinate point of the outline data corresponds to for each coordinate point, a direct slope formula can be obtained for the X and Y axes, so that it can be generated from Each coordinate point (X,
Y) Calculate the magnification of the character pattern data from the outline character pattern data given to the information and the specified output character size, and calculate the specified character size from the slope formula given to each coordinate point (X, Y) above. By having an arithmetic unit that calculates and sends out each coordinate point of the size, it is possible to obtain high-quality character pattern data for any character size.

〔Example〕

The character pattern generator of the present invention generates from the same pattern data a thick, solid character design designed for large characters and a design for small characters with wide line spacing excluding decorative parts and emphasizing readability. FIG. 1 is a block diagram of one embodiment of the present invention. FIGS. 2(a) and 2(b) are examples of character pattern data of this embodiment.

In FIG. 1, 1 is a character pattern data storage section, 2 is a character data reading section, 3 is a calculation section, 4 is a development section, and 5 is a contour data filling section.

The character pattern storage unit 1 stores coordinate points (Xn,
Information on coordinate movement associated with expansion/reduction for each Yn) (tilt type)
Contains character data based on coordinate points given.

The one-character sentence data read by code specification is
The one-character data is stored in the reading unit 2 and sent to the calculation unit 3 for each coordinate point.

The calculation unit 3 applies the magnification obtained by specifying the character size to each coordinate value of the read character data and performs calculation. To explain with reference to the diagram drawn in the calculation unit 3 of FIG. 1, each coordinate point of the triangle of large character data (X+ Y+ ~
3) are shown as 3/=aX+b, x=a Y+b', respectively, when the values of x and y are a magnification of 1, and these values are multiplied by a magnification of XI,'lx~X,,y. is obtained by calculation. Each coordinate point (XI,
yt~X3, 3'3) is sent to the developing section 4 and becomes a character image of the outline, and is outputted to the printer as a character image by filling in 5.

〔Effect of the invention〕

As explained above, the present invention has the advantage that by specifying an output size using one type of character pattern data, it is possible to obtain a character design output that matches the size.
