Description

[Detailed description of the invention] 〔overview〕 When expanding a character pattern vertically by an arbitrary multiple.

First, by using a copying function, a plurality of character patterns (in multiples) are arranged in the horizontal direction, and then only the area is line-scanned by a primary conversion function to convert it into a one-dimensional array in the vertical direction, thereby obtaining an enlarged character pattern.

[Industrial application field]

The present invention relates to a method for enlarging character patterns such as Chinese characters that are output to a printer or a display device.

[Conventional technology]

When creating documents or processing graphics using a computer.

Expanded characters are often used for titles, etc.

An enlarged character is one in which either the vertical size or the horizontal size, or both, of a basic (standard) character pattern are enlarged multiple times.

Among these, the present invention particularly relates to a technique for enlarging only the vertical size of a character pattern multiple times.

Normally, the standard size character pattern is 16x16
Each character is represented by a dot matrix of a fixed size, such as a dot or 24 x 24 dots.

If each horizontal dot arrangement of such a dot matrix is called "row data", then the conventional method for vertically expanding a nine-character pattern is as follows.

Each row of data in a character pattern was arranged in a vertically overlapping manner by the magnification multiple value.

FIG. 3 shows the case of double enlargement in the vertical direction.

This figure shows an example of processing using a conventional method. In the figure, 31 is an original character pattern area on memory.

32 is an enlarged character pattern area on the memory as well.

Also, ■, ■, . . . represent line data of the original character pattern.

Each line of data ■, ■ in the original character pattern area 31.

. . are sequentially read out and duplicated one line at a time and copied into the enlarged character pattern area 32. As a result, the number of lines in the vertical direction is doubled, and a character pattern that is twice as long vertically is created.

[Problem that the invention seeks to solve]

With conventional character pattern enlargement methods, when attempting to enlarge multiple times, it is necessary to copy each line of character pattern data multiple times on the screen, making the procedure complicated and difficult to operate. There was a problem that it was troublesome and time consuming.

[Means for solving problems]

The present invention utilizes a rectangular area copying function and a one-dimensional transformation function that are generally used in image processing.

To easily realize vertical character pattern enlargement by any number of times.

This one-dimensional conversion function of a rectangular area reads and scans an arbitrary rectangular area on the bitmap screen in a line shape, for example, in byte or multi-byte data units, and converts data of the same read data unit size. , which is a sequential one-dimensional rearrangement (the area of the region does not change)
.

ν In the present invention, a plurality of original character patterns to be enlarged multiple times are copied so as to be lined up in the horizontal direction.

By applying a one-dimensional conversion function to the entire image, it is possible to obtain a character pattern enlarged by any number of times with a simple operation.

The present invention will be explained in detail with reference to FIG.

(a) in Figure 1 is a processing stage in which a plurality of original character patterns are copied equal to the enlargement factor, and (b) in Figure 1 is a processing stage in which a one-dimensional conversion function is applied to a plurality of copied original character patterns. 3 shows the processing steps for creating an enlarged character pattern.

In the figure, 1 is original character pattern data of a predetermined rectangular area to be enlarged. And 1′, 1″.

r is three copied original character patterns in the example of three times enlargement, and 2 is an enlarged character pattern. Also ■, ■′, ■″, ■1.■, ■′.

■“, ■1, . . . each represent sequential line data of the original character pattern.

[Effect]

According to the present invention, if the vertical magnification factor of a 9-character pattern is n, the original character pattern is copied by n adjacent characters as illustrated in FIG. , the entire n original character patterns are regarded as one rectangular area, and as shown in Figure 1(b), ■', ■', ■',
The line data of each copied original character pattern is successively read out in the order of ■', ■'', ■~, . . . and arranged one-dimensionally in the vertical direction to generate an enlarged character pattern 2.

〔Example〕

FIG. 2 is a block diagram of an apparatus according to an embodiment of the present invention.

In the figure, 21 is a processing device, 22 is a screen memory, and 23
24 is a character pattern memory, 24 is a screen editing processing section, 25 is an area copy function, 26 is a one-dimensional conversion function, 27 is a keyboard, 28 is a display device, and 29 is a printer.

The screen memory 22 is a bitmap memory that corresponds to the display screen of the display device 28 (or may correspond to the output screen of the printer 29).

The character pattern memory 23 contains usable kanji.

Each pattern of numbers, symbols, etc. is held in a standard-sized donto matrix.

The screen editing processing section 24 uses the two-screen memory 22 as a working memory to perform graphic processing, and when writing nine characters, extracts character pattern data from the two-character pattern memory 23 and writes it into the screen memory 22.

Next, call the one-dimensional conversion function 26 from the keyboard,
A rectangular area of the entire plurality of copied original character patterns is specified, one-dimensional conversion is performed, and the result is written in the writing position of the screen memory 22 as enlarged character pattern data.

In this way, an enlarged character pattern of any desired enlargement factor can be easily created and displayed on the display device 28 or outputted to the printer 29.

〔Effect of the invention〕

According to the present invention, it is possible to generate vertically long patterns such as Chinese characters at relatively high speed. Further, if an appropriate means for enlarging a pattern horizontally at high speed is also used, arbitrary pattern data can be enlarged n times vertically and horizontally at high speed.
