Abstract

PURPOSE:To easily represent a character of optional size by determining a character pattern of specific size among character patterns which are provided previously and displaying a rectangle as an external frame together with the determined character pattern at the same time. CONSTITUTION:A means 4 which determines the character pattern of the specific size among the previously provided character patterns and a means 6 which displays the rectangle as the external frame at the same time are provided. A character itself is displayed in its pattern which is prepared on the system side as it is and the size of the character is indicated by drawing the rectangle which shows the actual size around the character. Here, character patterns which are prepared on the system side are displayed as they are to represent the contents of characters without any error. Further, the external frame of the character is drawn rectangularly to represent the actual size of the character without any error and characters of optional size are represented artificially on a display device without any special preparation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character display system for electronic computers, and particularly to a character size representation system suitable for expressing characters of arbitrary size on a display device.

[Conventional technology]

When using a computer as a document creation support system and laying out a document etc. while looking at the display device and printing it out, the size of the characters on the display device and the size of the final printed characters are It is desirable that it is compatible.

On the other hand, there are limits to the character patterns that can be prepared by the system (for example, standard size, double height and width, and 1/4 time).
It is impossible to display characters of arbitrary size. If you want to display characters of a size other than the character patterns prepared by the system, conventionally you have to prepare the necessary character patterns yourself, or you can convert the character patterns prepared by the system with a program. It was expanding and contracting.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the method of preparing the necessary character patterns by yourself requires preparing a huge amount of character patterns in order to display characters of any size, so in reality, it is necessary to prepare several types of character patterns. It was only possible to display the following characters, and there were problems in terms of ease of document layout, versatility, etc. In addition, the method of enlarging/reducing using a program does not take into account the ease of processing or the time required for conversion, and when enlarging/reducing at any magnification ratio, it is difficult to ensure that the converted character pattern does not become difficult to see. to do so,
There was a problem in that advanced conversion technology was required.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, an object of the present invention is to provide a method for easily expressing characters of any size on a display device of an electronic computer.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a means for inputting arbitrary character sizes and characters to be displayed in a computer equipped with a display device and character patterns of one or more sizes to be displayed on the display device. , means for generating a rectangle corresponding to the input character size; means for determining a character pattern of a predetermined size from character patterns prepared in advance according to the input character size; The present invention is characterized by providing means for simultaneously displaying a rectangle as an outer frame.

[For production]

In the present invention, each character itself is displayed as is in the character pattern prepared on the system side in N, while the size of the character is shown by drawing a rectangle representing the actual size around each character.

With this N, the content of one character can be expressed without error by displaying the character pattern prepared on the system side as is. Furthermore, by drawing a rectangle as the outer frame of the character, the actual size of the character can be expressed without error. Thereby, characters of any size can be displayed in a pseudo manner on the display device without any special preparation.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention, showing the process of drawing a rectangle representing a character and its actual size on a display device of a computer.

In FIG. 1, a display position input section 1 inputs the position on the display screen of a display device where characters are to be displayed. The input is
You can enter the coordinate position directly from the keyboard, or you can specify it with a pointing device such as a mouse and convert it to a coordinate position.
shall be.

In the character size input section 2, the size of the character 1 to be displayed is entered.The size of the 0 character can be specified by specifying the horizontal and vertical lengths from the keyboard, as with the display position above, or indirectly. You can also specify the number of points, etc., and convert this to the length in the vertical and horizontal directions. Let m be the input horizontal length and n be the input vertical length.

In the display character input section 3, characters to be actually displayed on the display screen are input. In step 25, it is assumed that the character "kan" is input.

The drawn character size calculation unit 4 determines which size of character pattern to use from among the character patterns prepared on the system side. At this time, from the lengths in the vertical and horizontal directions input in the character size input section 2, the maximum pattern that fits within these lengths is determined.

Let the horizontal length of the obtained character pattern be a, and the vertical length be b.

The character drawing position calculating section 5 calculates the coordinate position on the display screen where the size of the character pattern determined by the drawing character size calculating section 4 should be actually drawn. Coordinate position (X', Y'
) is calculated using the following formula.

X' = X ten (m-a)/2 Y'=Y+(n-b)/2 The rectangle drawing unit 6 draws the coordinate position (X) on the display screen.

Draw a rectangle with horizontal length m and vertical length n using Y) as a reference.

The character drawing section 7 calculates the coordinate position x' on the display screen.

Y'), the characters input from the display character human power section 3 are drawn in a character pattern of the size determined by the drawn character size calculation section 4.

Through the above operations, one character and a rectangle are displayed on the display device as shown in FIG. In 2\, the character 101 is displayed in the size of the character pattern prepared by the system, but the rectangle 102 shows its actual size.
With simple operations, characters of any size can be displayed on the display screen, making it easier to layout documents while looking at the display screen.

FIG. 3 is a system configuration diagram of an electronic computer to which the present invention is applied. Data input by key operations on the keyboard 10 is analyzed and analyzed by the central processing unit 20 according to each program 31 to 37 stored in the memory 30.
Processed, rectangle drawing data 38 and character drawing data 3
