Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous character creating method, which can be used as, for example, an output function of a Japanese word processor to continuously print characters in a writing brush.

[Summary of the Invention] In the present invention, in a continuous character creation method in which character fonts are continuously connected, information regarding the positions of the starting and ending strokes is provided as information of each character, and the first character (preceding character) that is the object of continuous writing When the second character (post-character) is given, whether or not continuous replenishment of both characters is determined based on the positional relationship between the end-writing position of the first character and the starting position of the second character. Characters can be created.

[Prior Art] It has been difficult to continuously connect arbitrary characters to each other by the conventional continuous character method. The reason is that the conventional technology does not "create" a region that connects character fonts and character fonts, that is, a continuous part. Instead, a similar method to logo printing is used in memory. This is because the continuous character font string is provided from the beginning, and only the process of simply reading out the character font string is performed at the time of printing. In the case of this method, the character font string is nothing but the continuous character pattern of the fixed phrase, and if a large number of character font strings are prepared, in practice,
There is no limit to the combination of characters that can be repeated, but
Therefore, the memory capacity required becomes enormous.

Therefore, the applicant of the present application is the Japanese Patent Application filed on May 31, 1986.
In No. 61-126011, a method for automatically creating a continuous portion of a character font and a character font is proposed. With this method, it becomes possible to continuously connect arbitrary characters.

[Problems to be Solved by the Invention] However, it is clear that if the characters are continuously linked, "readableness" and "naturalness" are impaired, and a solution in this respect remains as a problem. Has been done. In other words, it is better not to repeat characters that are difficult to read and become unnatural when repeated, but the problem is what kind of condition should be taken to determine whether or not continuous repetition is possible.

Therefore, it is an object of the present invention to provide a continuous character creating method that determines whether continuous characters between characters can be combined or not based on a new continuous character compatibility condition, thereby improving the readability and naturalness of continuous characters. .

[Means for Solving Problems] FIG. 1 is a functional block diagram of the present invention. In this figure, A is a brush stroke end stroke position storage means for storing the strokes of each character, and B is a stroke end position for the first character and a stroke position for the second character from this stroke end stroke position storage means. C is a continuation possibility determining means for deciding whether or not to create a continuous portion of both characters based on the positional relationship between the end stroke position of the first character and the stroke position of the second character. .

[Advantageous Effects of the Invention] In the present invention, when characters are continuously connected, a character (second character) after the last stroke of the preceding character (first character) is written.
When the distance to the writing position is too long, the continuous portion becomes too long and hard to read. Since the continuation is performed in consideration of the gap between the finish stroke and the brush stroke, in the present invention, as shown by the stroke finish stroke position storage means A in FIG. 1, the position of the stroke stroke and the stroke stroke is added as additional information of each character. It has information. Then, with respect to the first character and the second character that are the objects of the continuous availability determination, the extracting unit B is caused to extract the end-stroke position information of the first character and the stroke position information of the second character,
The continuous cotton availability determining means C determines the availability of continuous cotton based on the positional relationship between the two.

For example, the position information of the stroke and the end stroke has a format of X and Y coordinates in the matrix of each character font, and the continuous availability determination means C determines the coordinate components of the end stroke of the first character and the stroke of the second character. If the difference is smaller than the predetermined reference value, it is determined that continuous connection is possible.

The above-mentioned reference value that defines the continuous range between characters can be a value common to all characters, but by setting a unique value for each character, the beauty of continuous characters can be improved. it can.

In addition, by making the above-mentioned reference value user programmable, it is possible to add variations to the continuous characters and to reflect the user's preference.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows the block configuration of this embodiment. This embodiment is implemented on a Japanese word processor, and has a function of determining whether or not continuous writing is possible based on the positional relationship between the writing and the ending of the hiragana in hiragana style, and performing continuous printing.

Reference numeral 1 is a document data memory for storing document data in a JIS code format, for example.

Reference numeral 2 denotes a continuous specified range memory that stores range data of strokes and end strokes that may be repeated between characters. Here, the user can specify the range for each character. The range information is given by the length in the x direction and the length in the y direction.

Reference numeral 3 denotes a print control unit which, when a range of continuous cotton is specified via an input device (not shown) (not shown), sets the information in the continuous range specified memory 2 and when a continuous print command is given. The continuous printing described later is executed.

Reference numeral 4 is a font file structure table, and in this table memory, as shown in FIG.
Up to the reading (character code), character font data, character writing data X ₁ , Y ₁ , final writing data X ₂ , Y ₂ , interpolation data X ₃ used in spline calculation to determine continuous parts,
Y ₃ etc. are included. Figure 4 shows the character font and brush strokes,
This is an example of the relationship between the final writing and the interpolation data. In addition,
In this example, since the range data in the continuous specified range memory 2 is set for each character, each range data is linked to the corresponding character information in the font file structure table.

In the output character storage area (output buffer) 5, character information of the preceding character and the succeeding character extracted from the continuous specified range memory 2 and the font file structure table 4 is placed.

The continuous strip check creating unit 6 determines whether continuous striping between characters is possible by using the character information stored in the output character storage area 5, and when continuous stripping is possible, activates the cubic spline calculation unit 7 to calculate the continuous strip portion. .

The processing performed by the cubic spline calculation unit 7 is the above-mentioned Japanese Patent Application No. 61.
Since it is described in detail in No. -126011, its explanation is omitted.

8 is a printing device such as a page printer, and 9
Is the printed matter.

FIG. 5 illustrates the principle of success / failure in this embodiment.
As shown in (a), the final stroke coordinates (x,
y) and the stroke (x ', y') of the latter letter "te" are not so far apart, that is, the difference in the x direction (x-
If the difference (y−y ′) between x ′) and the y direction is smaller than the values l _x and l _y set in the continuous cotton designation range memory 2, it is determined that continuous cotton is possible and the continuous cotton portion is printed. On the other hand, as shown in (b), when the difference between the end stroke coordinate of the front character "se" and the start stroke coordinate of the rear character "zu" exceeds the set specified range, it is determined that continuous line is not possible and the continuous line portion is Is not created.

FIG. 6 shows a general flow of continuous printing processing, which is entered when the start of continuous printing of cursive is instructed after setting the range of the document to be printed and other necessary formats.

The print control unit 3 controls the font file structure table 4
Then, the character information for one character is taken out from the continuous specified range memory 2 and placed in the output character storage area 5 (S1). If the data pointer points to the first character of the printed document,
The character font is printed (S2, S3), the character information of the printed character is used as the previous character information, the data point is advanced by one (S4), and the process returns to the extraction of the next character information.

If the extracted character information is not the first character information, the continuous character check subroutine for each character (S5) until the completion of printing the last character is indicated by the data pointer (S5)
6) is executed to decide whether or not continuous characters can be added to the preceding character of the current character (after character), the continuous character part is created and printed according to the determination result, and the next character processing is performed.

FIG. 7 is a detailed flow of the continuous cotton check subroutine. As shown in FIG. 7, at T1, the continuous cotton check creating unit 6 stores the x-direction data in the continuous cotton specified range of the subsequent character information in the internal register.
l _x , data in the y direction is l _y , x coordinate of the last stroke position of the previous character is x, y coordinate is y, and x coordinate of the current character stroke position is x ′, y
Read the coordinates into y '. Calculate (xx-x ') at T2,
Compare the size with l _x . (X-x ') calculated value of not perform the calculation of unbroken portion as shown by T3 when exceeds the l _x. If it is within l _x as shown by T4 calculates (y'-y), comparing the l _y and sizes, the flow without unbroken part of creating as shown by T5 when exceeds the l _y Exit through.

The difference between the end x coordinate of the previous character and the x coordinate of the current character (x-
x6) is within the set value l _x , and the difference (y′−y) between the y coordinate of the previous character and the y coordinate of the current character is also within the set value l _y, it is indicated by T6. Is subject to continuous cotton,
The continuous cotton part is created and printed (T7).

[Effects of the Invention] As described in detail above, the present invention is in accordance with the basic property of continuous strips that it becomes difficult to read if the continuous strips are too long. Have it,
Since the continuation of the continuation is decided according to the positional relationship between the end stroke of the preceding character and the stroke of the succeeding character, there is an advantage that the continuation is naturally performed by combining the characters.
