Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous character creating device, for example,
By incorporating it as an output function of a Japanese word processor, etc., it can be used for continuous printing of characters in a writing style.

[Summary of the Invention] The present invention, when creating continuous characters in which characters are created by creating continuous parts between character fonts, as information of each character, information about the position of the starting and ending strokes and the creation of the character. Limit information that allows the position to be shifted is provided, and condition information about the continuous range between characters is prepared.Regarding the front character and the rear character to be created, the position of the end stroke of the front character and the stroke of the back character When the relationship is within the continuous range, the two characters are continuous without shifting the creation position of both characters, and when the above positional relationship is outside the continuous range, continuous characters are within the limit of the deviation of the succeeding characters. Since the deviation that satisfies the condition of the possible range is calculated, and the created position of the subsequent character is shifted by the calculated deviation so as to be continuous with the preceding character, it is possible to obtain a natural continuous continuous character with various changes.

[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 without increasing the memory capacity.

[Problems to be Solved by the Invention] By the way, when a character string is developed on an output medium or an image memory, the font of each character forming the character string is generally placed at a fixed position determined by the format setting. Typically, the size of each character font is the same (for example, a 24 × 24 matrix configuration), and each character font is arranged in a straight line with a character pitch according to the format setting. For example, it is similar to inserting a character font of the same size into a grid-like character box on the manuscript paper. The squares are straight, so that a string of character fonts is created around the center line of the squares.

However, when creating continuous writing characters in calligraphy typeface, the condition that the character creation position is fixed and the center line of each character box becomes a straight line, as described above, causes the continuous continuous characters that are created to vary. Make something. Furthermore, it is not uncommon for unnatural continuous characters to be created. For example, the hiragana “shi” in cursive writing is often written in a handwritten brush with a horizontal shift.

Since the present invention has been made in view of such circumstances,
It is an object of the present invention to provide a continuous cotton character creating device that creates continuous and natural cotton characters with variations.

[Means for Solving Problems] FIG. 1 is a functional block diagram of the present invention. In the figure, A is a writing stroke end position storage means for storing the position information of the stroke and end stroke of each character, B is a shift limit storage means for storing the shift limit at which the creation position of each character can be shifted, and C Is a permissible positional relationship storage means for storing the continuous range of characters, and D is a permissible positional relationship storage means for the positional relationship between the end-writing position of the first character (previous character) and the starting position of the second character (post-character). If the condition stored in the above is satisfied, the normal continuous running means for connecting the first character to the first character without changing the created position of the second character, and E is the allowable positional relationship storing means for the positional relationship between the first character and the second character. If the condition set in is not satisfied, the deviation that satisfies the condition is calculated within the limit of the deviation allowed for the second character, and the second character is shifted by this deviation, and the second character is continuously shifted. It is a means.

According to the present invention, when the positional relationship between the end stroke of the first character and the stroke of the second character is within the continuous range, with respect to the first character and the second character to be created. Is usually continuous running means D,
A continuous portion of both characters is created without shifting the creation position of the characters. However, even when the positional relationship between the end stroke of the first character and the stroke of the second character is outside the continuous range, it is not immediately impossible. That is, it is possible to shift the creation position of the second character (hence the writing position) within the range of the shift limit stored in the shift limit storage unit B, and satisfy the condition of the continuous range within this shift limit. Whether or not there is a deviation is analyzed by the deviation continuation executing means E. If such a deviation does not exist, continuous printing is not possible, continuous printing of characters is not performed, and characters are simply created at their normal creation positions. However, if such a deviation exists,
The position where the second character is created (and thus the writing position as well) is displaced by that amount, and the second character is linked to the first character at the displaced position.

The shift limit information is individual information for each character, and therefore, it is possible to assign a relatively small limit value to one character and a relatively large limit value to another character.

Normally, the continuous string execution means D performs inter-character continuous cotton without deviation in the character creation position, and the shifted continuous string execution means E performs the continuous character string in a manner in which the character creation position is shifted. Which is executed? Depends on the information assigned to each character. Therefore, not only the regular continuous cotton strips but also the continuous continuous cotton strips are performed according to the type of the character, and it is possible to obtain continuous and continuous cotton letters with variations.

In order to reflect the user's preference and the like, the shift continuation execution means E may be activated only when the user desires the shift continuous shift.

By making the information on the shift limit user programmable, various patterns of continuous characters can be obtained, which contributes to the enrichment of continuous variations and reflects the user's intention.

[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. The present embodiment is realized on a Japanese word processor and has a function of continuously printing cursive-style hiragana while appropriately shifting the character creation position.

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 range designation range memory that stores range data of strokes and end strokes between characters that may be repeated, and the user can specify the range here. 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. In addition, the deviation flag is specified when deviation continuation is specified.
Set up 3a and set the shift continuous mode.

Reference numeral 4 is a font file structure table, and in this table memory, as shown in FIG. 3, reading (character code) from "a" to "n", character font data, and character writing data X ₁ , Y ₁ , final stroke data X ₂ , Y ₂ , interpolation data X ₃ used in spline calculation to determine continuous portion,
Y _3, moving allowance capable of moving the writing position of a character font to the left and right (dots) and the like are included. Fourth
The figure exemplifies the relationship between the character font and the stroke, finish, and interpolation data.

In the output character storage area 5, character information and the like of the preceding character and the succeeding character extracted from the font file structure table 4 are placed.

The continuous-feed check creating unit 6 inspects whether or not the normal continuous-feed has no deviation in the character creation position. If it is not possible, the continuous continuous-feed is inspected. If the continuous-feed is possible, the necessary position information is calculated by the third spline. It is passed to the part 7 and the continuous portion is calculated.

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 shows the operation of this embodiment in a straightforward manner. As shown in FIG. 5A, the difference between the final stroke coordinate of the preceding character "sa" and the stroke coordinate of the subsequent character "shi" indicates the continuous range designation range memory. Range set to 2
When it is within l _x and l _y , the position of "shi" is not shifted and continuous. On the other hand, as shown in (b), when the difference between the ending X coordinate of the preceding character “re” and the starting X coordinate of the succeeding character “shi” is not within the specified range of l _x , the succeeding character “shi” is moved to the right. Direction (X-axis positive direction)
Move to and continue. As shown in (b), it is more natural for the "shi" to be shifted to the right, and if you continue to put it in the original position, you may mistakenly read "reshi" as "ashi", and in terms of readability as well. It becomes a problem.

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
The character information for one character is taken out 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, and the data pointer is advanced by one (S4), then the next character. Return to the extraction of the character information of.

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 determine whether or not normal continuous printing and offset continuous printing are possible with respect to the preceding character of the current character (after character), and the continuous printing portion is created and printed according to the determination result, and the process proceeds to the next character processing.

FIG. 7 is a detailed flow of the continuous cotton check subroutine. As shown in T1, first, the xy coordinate data of the continuous cotton specified range is set to l _x and l _y , and the final stroke coordinate data of the previous character is set to x and y. The stroke coordinate data of the character is set to x'and y ', and the movement allowable range data of the current character is set to E. Then, as shown in T2, the difference between the end x coordinate of the previous character and the x coordinate of the stroke of the subsequent character (xx−x ′)
Is calculated and compared with l _x . If the difference in the left-right direction (x direction) between the two strokes is greater than l _x , the process proceeds to the process of shifting continuation described below, but if it is within l _x , it is not necessary to shift the current character, so T3 As shown by, the current character is printed from the brush coordinates of the current character. Subsequently, as indicated by T4, the difference (distance in the vertical direction) between the last stroke y coordinate of the previous character and the current stroke y coordinate of the current character is calculated and compared with the designated value l _y . If the value is larger than the specified value l _y, it is not possible to continue, so the process returns to the general flow for processing the next character without creating a continuous part. Difference (x-
When x ') is within l _x and the difference (y'-y) is also within l _y , a continuous cotton portion between the current character and the previous character without displacement is created and printed (T5).

On the other hand, in the case of shift continuous processing, it is checked at T6 whether shift continuous is instructed by the shift flag. If not, continuous printing is not possible and the current character is simply printed at the normal position (T7).

If the shift continuation is instructed, the initial value x'is set in Sx (T8) and the following processing is repeated.

At T9, add x '+ 1 (corresponding to shifting the print position of the current character to the right by one dot), and at T10, check the difference with the initial value Sx to see if it is within the allowable movement range E, and within the range. If there is a deviation of x, the difference (x−x−d) between the value x ′ of the stroke x coordinate of the current character and the value x ′ of the stroke x coordinate of the previous character shifted at T11.
x '), and this difference indicates the continuous range in x direction l _x
If it is not within l _x , return to T9.

When the deviation (x'-Sx) of the current character exceeds the allowable value E,
Since continuous printing is not possible, print the current character from Sx (T12) and do not create continuous printing.

Before shift increment is the current character (x'-Sx) reaches its permissible value E, when the difference in the x direction and stroke end before the character (x-x ') becomes within l _x is The current character is printed from the offset position x'at that time (T13), and between the shifted writing position (x ', y') of the current character and the ending writing position (x, y) of the previous character. Create a continuous cotton part and print it (T1
Five).

In the above embodiment, continuous printing can be performed by shifting the character position to the left and right, but continuous printing can be performed by shifting the character vertically.

[Effect of the Invention] As described in detail above, in the present invention, the movable range of the character position is set for each character, and the character creation position is moved within this range so that it can be linked with the preceding character. You can get a continuous flow of letters. Also, when the positional relationship between the front character and the rear character for the final brush stroke satisfies a predetermined condition, the characters are continuously moved at the normal position, and therefore the continuous cotton pattern that is not misaligned with the continuous cotton pattern is not misaligned. The patterns will be mixed and variations will be added.
