Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document output device for producing output image data which is information of ON / OFF of pixels of a printer device or a display device for visualizing and printing the shape of a character and displaying or displaying. In particular, the present invention relates to a process for appropriately aligning images of characters in a horizontal writing document.

[0002]

2. Description of the Related Art Conventionally, this type of output device generates a character image which is image data of a character from shape data defining a shape of the character, and the character image is image data assuming pixels of an output medium. By arranging on the output image, the output image referred to by the output device is generated. Here, the image data represents data defining ON / OFF of pixels.

In addition to the above-mentioned shape data, the information relating to characters (hereinafter referred to as character data) includes arrangement data as information necessary for arranging each character to form a character string. Contains character feed data and baseline data.

The character feed data defines an existing area in the character feed direction of each character, that is, a character width, and has coordinate information of a start point and an end point of the existing area. Normally, since the direction of character feed includes horizontal writing and vertical writing, this character feeding data is also for horizontal writing and for vertical writing, and some have both. For example, as shown in FIG. 2, the character feed data for horizontal writing is
It has the coordinate information in the x direction, which is the character feed direction, and the coordinate information of the starting point (generally 0) which is the starting position of the area where the character exists, and the ending position thereof and the position which should coincide with the starting point of the next character. It consists of coordinate information of the end point.

The baseline data defines a position (hereinafter referred to as a baseline) that serves as a reference for character alignment in a direction orthogonal to the character feed direction, and has coordinate information in that direction. It is a thing. Similar to the character feed data, there are horizontal writing data, vertical writing data, and both. For example,
In FIG. 2, the baseline data for horizontal writing is the y coordinate, and has the coordinate information of the position (generally 0) that is the reference for the alignment of the character shapes.

Conventionally, when arranging each character image on the output image, the start point of the character feed data of each character is made to coincide with the coordinate position in the designated character feed direction, and the base indicated by the baseline data of that character is used. Characters are arranged by matching the line with the coordinate position in the direction orthogonal to the designated character feed direction. For example, when arranging a character in horizontal writing, the character image is made so that the coordinates of the starting point of the horizontal writing character feed data match the specified x coordinate and the coordinates of the horizontal writing baseline match the specified y coordinate. It was placed on the output image.

Regarding the baseline position, in general,
For vertical writing, regardless of the type of character, it is set at a position that passes through the center of the design of the character.For horizontal writing, in the typeface (font) with only English characters, it is set near the bottom of the capital letters. In many Japanese typefaces including characters, kana, and kanji, they are set at a position that passes through the center of the character design.

Generally, the Japanese character set character set includes English characters in addition to Kana and Kanji, and this English character takes into consideration the balance of the vertical position of the Kana and Kanji. Is designed. That is, in the case of horizontal writing, when the arrangement is performed using the baseline data according to the setting of the baseline position as described above, the kana and kanji obviously fall too much with respect to the English characters, and the balance is deteriorated. Therefore, when creating font data, it is necessary to balance the design by lowering the position of English characters from the baseline or raising the positions of kana and kanji above the baseline. Generally, the baseline data for horizontal writing is considered on the basis of English characters that are required to have good balance when arranged horizontally, and the position of the kana or kanji shape data is raised above the baseline, that is, as shown in FIG. As shown in, font data is created by adjusting the baseline data of each character so that the baseline is located slightly below the center of the character.

FIG. 4 shows a document output device capable of using a type A and a type B in which the gap between the horizontal writing baseline and the character center is different, and a horizontal writing document in which these two types are mixed is output. In case of type A and type B
FIG. 6 is a diagram showing a positional relationship between a horizontal writing baseline and character shape data. Here, the straight line 41 represents the position of the baseline, the character 42 is one character of the type A, and the character 43 is one character of the type B. Point 44 and point 45 indicate the center points of the characters 42 and 43, respectively, and distance 46 and distance 47 indicate the character 42, respectively.
And the distance between the baseline of the character 43 and the center point of the character, that is, the gap. Distance 4
The 6 is designed to be smaller than the distance 47.

[0010]

However, the design balance as described above is rarely taken into consideration beyond the typeface, and generally, the baseline position and the design center of the character are not considered. The difference between is different for each typeface.

Therefore, in recent years, in this type of document output device, it has become possible to relatively easily add typeface data in which character data is stored for each typeface from the outside, and a document using a plurality of typefaces is output. However, in that case, a problem arises in which characters of multiple typefaces cannot be arranged beautifully when combined.

For example, kanji of type A and kana of type B,
Assuming that a document using English characters is output by a conventional document output device, as shown in FIG. 5 (a), the layout is such that the kana of typeface B is unnaturally raised with respect to the kanji of typeface A. It will be in a state. Note that the straight line 51 indicates an auxiliary line indicating the coordinate for the alignment of this row.

As described above, when a document using a plurality of typefaces and a plurality of sizes of characters is arranged by the conventional method of matching the baselines as described above, the characters are not aligned and an unattractive output result is produced. There is.

The present invention has been made to solve the above-mentioned problems, and a plurality of different baselines indicated by the baseline data in the character data and the design center of the character image have different differences. An object of the present invention is to provide a document output device capable of obtaining an output result in which characters are beautifully arranged without changing the form of conventional character data even in a document in which typeface characters are mixed.

The working memory 12 stores temporary data when the processing of the program stored in the program memory 11 is executed by the CPU 10, and the character image memory 12a used in the processing in this embodiment described later, It also includes a character feed memory 12b, a baseline memory 12c, and a position coordinate memory 12d.

The font memory 13 is a database that stores character data 19 that is information for generating a character image that is character image data. The character data 19 is the shape data 19
a, character feed data 19b and baseline data 19
It is composed of c. The character data 19 of the font memory 13 can be read by specifying the typeface and the character. In this embodiment, a typeface is expressed by a numerical value uniquely indicating a typeface called a typeface code, and a character is expressed by a numerical value uniquely indicating a character called a character code.

Shape data 19a of the character data 19
Is information defining the shape of the character, which is stored in the bitmap format in this embodiment. As described in the section of the prior art, the character feed data 19b is information that defines the existence area of the character in the character feed direction. In the present embodiment, the x coordinate value of the start point for horizontal writing and the x coordinate value of the end point. , The y-coordinate value of the start point and the y-coordinate value of the end point for vertical writing are stored. Further, the baseline data 19c is information of alignment in the direction orthogonal to the character feed direction of the character, as described in the section of the prior art. In this embodiment, the y coordinate value for horizontal writing and the vertical writing are used. The x-coordinate value of is stored.

FIG. 2 conceptually shows an example of the character data 19 in the font memory 13. As shown in FIG. 2, the font memory 13 stores a bit map 21 as shape data 19a for each character data 19, and the x coordinate value of a point 22 as a horizontal writing start point of the character feed data 19b. The x-coordinate value of the point 23 is stored as the end point, the y-coordinate value of the point 24 is stored as the start point for vertical writing, the y-coordinate value of the point 25 is stored as the end point, and the baseline data 19c is stored. For horizontal writing, the y coordinate value of the straight line 26 is stored, and for vertical writing, the x coordinate value of the straight line 27 is stored. Bitmap 21
Is bitmap data having a width of W bits and a height of H bits, and is byte-aligned in the width direction so that the CPU 10 can handle it in byte units. If the width at this time is WB bytes, ON / OFF of 1/0
It is composed of WBxH byte array data represented by. At this time, the pixels are stored in order from left to right, left to right, and top to bottom.

The horizontal writing in the present embodiment means a format in which characters are arranged horizontally from left to right with respect to the character, and vertical writing is performed from the top to the character. A format in which characters are arranged horizontally downward.

The layout position memory 14 stores information about the layout position of the character image, and stores direction data 14a, standard position coordinate data 14b, kana / kanji position coordinate data 14c, and line feed width data 14d. There is.

The direction data 14a is information indicating the direction of character feeding, and is flag information indicating horizontal writing / vertical writing. The standard position coordinate data 14b and the kana / kanji position coordinate data 14c are data representing the positions of the characters to be placed together by the coordinate values on the output image, and the standard position coordinate data 14b is for processing characters other than kana and kanji. The kana / kanji position coordinate data 14c is information to be referred to when processing kana and kanji characters. The line feed width data 14d is data that represents the current line feed width in the amount of the coordinate unit of the output image.

The input section 15 is for inputting various commands such as a character output command accompanied by a typeface code and a character code, a line feed width setting, etc. The output image memory 16 is referred to by the display / printing device. In addition, an output image serving as output data of the document output device is stored.

The specific character code list 18 stores the specific character codes as an array of 2 bytes in ascending order (the order in which the codes gradually increase). It has been preliminarily investigated by statistical processing that the character codes stored here can be arranged more beautifully by performing a special processing as described later.

Next, the character image arranging process in the case of processing a horizontally-written document in the document output device thus constructed will be described with reference to the flowchart of FIG. It should be noted that this process is activated when a document in which a plurality of typefaces are mixed is output. In other cases, output processing is performed by the conventional method described in the section of the related art.

In this embodiment, by the time this process is performed, the initialization of all data in the arrangement position memory 14 has already been completed as follows. The direction data 14a sets "horizontal writing" as the character feed direction, the standard position coordinate data 14b sets the coordinate value on the output image of the position where the character is arranged, and the kana-kanji position coordinate data 14c is set. For the standard position coordinate data 14b, a value added to the y coordinate by 20% of the line feed width data 14d is set. The line feed width data 14d is set based on a command input from the input unit 15.

The CPU 10 first reads the character data of the character specified by the character code and the typeface code input from the input unit 15 from the font memory 13 to generate a character image, and the character image memory 12a in the working memory 12. The data is stored in (S31). At this time, font memory 1
From 3 onward, the horizontal character transfer data and the baseline data are simultaneously stored in the character transfer memory 12b and the baseline memory 12c in the working memory 12, respectively. Since the shape data of the character data stored in the font memory 13 of this embodiment is a bitmap, a character image can be obtained without any special conversion.

Next, the standard position coordinate data 14b is read from the arrangement position memory 14 into the position coordinate memory 12d in the working memory 12 (S32), and it is determined whether or not this character is a kana or kanji which is a specific character. Yes (S33). The determination is that the character code input from the input unit 15 is the specific character code list 18
Judgment is based on whether it is registered in.

If it is determined to be a kana or kanji character (YES in S33), the baseline of this character is recalculated without using the baseline data 19c stored as the character data 19 (S3).
4), position coordinate memory 12d in working memory 12
Is rewritten into the kana / kanji position coordinate data 14c of the arrangement position memory 14 (S35). The method for calculating the character baseline at this time is y for the character image.
The maximum value and the minimum value of the coordinates are obtained, and the coordinate value of the midpoint is rewritten as the baseline position of this character in the baseline data memory 12c in the working memory 12.

Here, the maximum and minimum values of the y coordinate of the character image are obtained as follows. First, the array data is examined in order from the beginning of the array data corresponding to the origin of the bit map data of the character, and the byte number of the memory in which 1 (pixel is on) is found first is determined,
The offset from the origin is calculated based on the width WB bytes of the bitmap data. This is the maximum value in the y direction.
Then, in the same manner, the array data is examined in the reverse direction from the end of the array data, and the offset from the last point is calculated depending on the byte number of the memory in which 1 is found first, and the minimum value in the y direction is calculated. Ask for.

Next, the CPU 10 makes the working memory 1
The character image stored in the character image memory 12a in 2 is arranged in the output image of the output image memory 16 (S36). That is, the x coordinate on the character image is the x coordinate value of the starting point of the character feed data stored in the character feed memory 12b, and the point represented by the baseline data stored in the baseline memory 12c is the position coordinate memory. It is arranged in the output image of the output image memory 16 so as to match the position coordinate data stored in 12d, and is written in the output image.

Subsequently, the standard position coordinate data 14b and the kana / kanji position coordinate data 14c in the arrangement position memory 14 are stored.
Is updated (S37). Here, the value obtained by subtracting the start point from the end point of the character feed data stored in the character feed memory 12b in the working memory 12, that is, the character feed amount is the x coordinate of the standard position coordinate data 14b and the kana / kanji position coordinate data 14c. Change to the value added to the value.

With the above, the character image layout process for one character is completed.

Next, a case will be described in which the same document as shown in FIG. 5A shown in the section of the prior art is output by this document output device.

First, when the character code indicating the character "I" is input from the input unit 15, as described above, the corresponding character data is read from the font memory 13 by the character code "I" and the typeface code. , A character image is generated and the data is stored in the character image memory 12a in the working memory 12 (S31). Then, the standard position coordinate data 14b is read from the arrangement position memory 14 into the position coordinate memory 12d in the working memory 12 (S3).
2).

Next, in S33, since "I" is a kanji character, YES is determined, and the process branches to perform the process of S34. Then, the baseline is recalculated from the character image of "I" (S34), and the working memory 1
The contents of the position coordinate memory 12d in 2 are rewritten to the kana / kanji position coordinate data 14c of the arrangement position memory 14 (S
35). After that, a process of arranging the character image of "I" stored in the character image memory 12a in the working memory 12 in the output image of the output image memory 16 is performed (S36). Subsequently, the standard position coordinate data 14b and the kana / kanji position coordinate data 14c in the arrangement position memory 14 are updated (S37). Above,
The character image placement process for "I" is completed.

Next, "ha" is input, and the processes of S31 and S32 are performed in the same manner. Since "ha" is a kana in S33, it is determined to be YES, and the process branches to S34 to perform the baseline correction process ( S34) and the position coordinate data correction process (S35) are performed, then the processes of S36 and S37 are performed, and the process of "ha" ends. Furthermore,
“Person”, “between”, and “de” are sequentially input. Since these are kana or kanji, YES is determined in S33, and baseline correction processing (S34) and position coordinate data correction processing (S35) are performed. , S36 and S37 are performed, and the process ends.

Finally, when "y" is input, since "y" is not a kana or kanji character, "NO" is determined in S33, the baseline correction process and the position coordinate data correction process are not performed, and the output of S36 is output. The character image is placed on the image, the position coordinate data updating process of S37 is performed, and the character image placement process of "y" is finished.

As a result of the above series of processing, the output result of FIG. 5B is obtained. The straight line 52 is the arrangement position memory 1
The line indicating the y-coordinate of the kana / kanji position coordinate data 14c stored in No. 4 and the straight line 53 are the standard position coordinate data 14
It is the line which showed the y coordinate of b.

As described above, according to the character image arranging process of the document output device, the kana and kanji are aligned at the center,
Also, the output results are obtained in which the English characters are aligned on the standard alignment line.

The storage means of the present invention corresponds to the area for storing the kana / kanji position coordinate data 14c of the arrangement position memory 14, and the processing of the calculation means is S in the flowchart of FIG.
The processing of the arranging means is S35.
Corresponds to the processing of S36. The process of the determination means corresponds to the process of S33 in the flowchart of FIG.

Here, in the above-described processing of correcting the baseline in S34, if the character image is divided into a predetermined ratio in the vertical direction, such as dividing into 6: 4 instead of the midpoint of the shape, Any position is acceptable. Also, S
In the processing of 34, the midpoint between the start point and the end point of the vertical writing character feed data can be used as a baseline correction value. That is, this can be done by reading the vertical writing character feed data of this character from the font memory 13 and calculating the midpoint between the start point and the end point. Also, as in the case where the coordinate values of the shape are used as parameters, not only the midpoint of the start point and the end point but also the point divided into 6: 4, if the start point and the end point are divided at a predetermined ratio ,
Any position is acceptable.

If the document to be processed does not include English characters, the kana / kanji determination process in S33 of the flowchart of FIG. 3 should be eliminated and the process of S34 to S35 should be executed at all times. You can also

Furthermore, in this embodiment, the baseline position is calculated for each character, but there are some fonts, such as Japanese typefaces, in which the maximum and minimum values of the character image are almost the same for each character. Therefore, every time the typeface changes, the baseline position is calculated based on a predetermined character, the calculated value is stored, and the stored value is output when the specific character of the typeface is output. May be used.

Further, the shape data 19a of this embodiment is
Although it was stored in a bitmap format and used directly without processing such as deformation, shape data is stored in a scalable font format such as outline format, and a character generator converts these data into the desired shape. It is also possible to generate an image and perform the above-described processing by using character feed data and baseline data according to the processing performed by the character generator.
The conversion process of the shape data into the character image by the character generator is not a main part of the present invention and is a well-known technique that has already been put into practical use, and therefore the description thereof will be omitted.

In this embodiment, kana and kanji position coordinate data 1
4c is stored as x and y coordinate values, but since the coordinate value in the character feed direction is the same as the standard position coordinate data, it is possible to store only the coordinate value in the direction orthogonal to the character feed direction. Further, the stored coordinate value may be stored as a relative amount from the standard position coordinate data. When the relative amount is stored, the process of S35 is a process of rewriting the contents of the position coordinate memory 12d in the working memory 12 to the standard position coordinate data 14b of the arrangement position memory 14 plus the kana / kanji position coordinate data 14c. .

Further, although the position coordinate data is two, that is, the standard position coordinate data 14b and the kana / kanji position coordinate data 14c, it is not limited to two and can be easily constructed to have a larger number of position coordinate data. Can be changed to By having a plurality of position coordinate data in this way, it is possible to perform finer correction by appropriately selecting a combination of different typefaces or corresponding to a more subdivided specific character group.

Further, a plurality of specific character code lists are stored in the memory according to the combination of typefaces used, the size of characters, etc., and when creating a document, depending on the situation such as which typeface is used. It is also possible to select and use an appropriate one from them.

For example, when a document in which the typefaces a, b and c are used, if the character size becomes larger than a predetermined value, the imbalance of the character arrangement of the specific characters of the typeface c becomes conspicuous. In addition, when it is known that the particular character of the typeface b also becomes unbalanced in the typeface a, a plurality of position coordinate data a, b, c and a plurality of specific types are specified so that these balances can be corrected. The character code lists b and c are stored in the memory in advance. Then, when a character is input to actually create a document, the character is arranged as follows.

First, it is determined which type of character the output character is based on the typeface code, and if it is typeface b, this typeface b is selected from a plurality of specific character code lists stored in the memory. The specific character code list b corresponding to is selected. It is determined whether or not the character to be output is included in this specific character code list b, and if it is included, the corresponding position coordinate data b is selected from a plurality of position coordinate data and the above-mentioned baseline A correction process or the like is performed, and the same placement process as the above-described process is performed.

If the character to be output is the typeface c, the character size is further checked. If it is larger than the predetermined value, the specific character code list c is selected from a plurality of specific character code lists. ,
It is determined whether or not the character to be output is included in the specific character code list c, and if it is included, the corresponding position coordinate data c is selected from a plurality of position coordinate data and the baseline correction is performed. Arrangement processing is performed by performing processing and the like. When the character is a character of typeface a or a character of typeface b or typec that is not included in the specific character code lists b and c, the placement processing is performed based on the position coordinate data a of the plurality of position coordinate data.

As a result, it is possible to specify the character more finely and to arrange the character more beautifully.

Further, in this embodiment, the line feed width data of 20 is used.
Although the% added to the standard position coordinate data 14b is used as the kana / kanji position coordinate data 14c, the percentage may be changed according to the line feed width or may be changed according to the character size. For example, if the line feed width is more than twice the character size, 10% of the line feed width data
When it is less than twice, processing such as adding 20% to the standard position coordinate data 14b to form the kana / kanji position coordinate data 14c may be performed. As a result, it is possible to prevent the character placement position from unnaturally moving up and down from the designated position.

In this embodiment, a method of processing the relative positional relationship between the standard position coordinate data 14b and the kana / kanji position coordinate data 14c with a fixed value is used. The values of the standard position coordinate data 14b and the kana / kanji position coordinate data 14c are obtained, and the arrangement position memory 1
It can be set to any value by rewriting the data in 4. As described above, if the data can be rewritten, it becomes possible to check the document once displayed or printed and to easily make corrections, or to freely set for each user. In addition, any form may be used as long as the information can identify the position where the character is arranged.

Further, in the present embodiment, an example in which the present invention is applied to Japanese Kana and Kanji has been shown, but the present invention is not limited to this.
In addition to kana and kanji, symbols such as “*” and “#” and a set including other characters may be used as the specific character.
Depending on the ratio of the specific character and the characters other than the specific character, the specific character code list 18
It may be considered that the character code other than the specific character is recorded in step S33 so that the determination in step S33 can be performed quickly. In that case, the determination in S33 can be dealt with by changing the process to S34 when it is not registered in the specific character code list 18.

Furthermore, by holding a specific character code list on a readable / writable memory and inputting a control code indicating addition or deletion and a character code to be added or deleted from the input unit 15 as necessary, A specific character code may be added or deleted. In that case, even when the user replaces some of the characters in the typeface with a character designed by him / herself, it is possible to make that character a specific character or not a specific character. It is possible and a beautiful arrangement is possible.

Further, in the determination, a method of collating a list of previously stored kana or kanji character codes is used, but the present invention is not limited to this, and an identifier corresponding to each character data is stored in advance (for example, , A table of pairs of character codes and identifiers is prepared), and in S33, when the identifier corresponding to the character code is read and it is shown that the identifier is a specific character such as Chinese character, the processes of S34 and S35 are performed. You can go.
Alternatively, the specific character can be designated by the range of the character code. For example, when the character code is a shift JIS code, the code range of kana or kanji is 0x829F to 0xEAA4.
If the code is within the range, YES is determined in S33. Any other method may be used as long as the character to which the present invention is applied can be specified.

The apparatus of the present embodiment is compatible with vertical writing, but may be an apparatus capable of only horizontal writing. In that case, the information on vertical writing of character data in the font memory 13 is: Direction data 1 in layout memory 14
4a may be omitted. However, when the process of S34 is executed using the character data that does not have the information related to the vertical writing, the correction point calculation process using the vertical writing character feed data, which is a modification example, cannot be performed. This is performed by the midpoint calculation process.

Besides, the present embodiment can be variously modified without departing from the spirit of the present invention.

As is apparent from the above description, according to the document output device of the first aspect of the invention, the coordinate position serving as the vertical arrangement reference of the character image data is based on the shape data in the character data. Are calculated by the same calculation method, and the coordinate position is placed at the vertical reference position on the output image data, so the baseline indicated by the baseline data of the placement data in the character data and the design of the character image Even in a document in which a plurality of typeface characters having different differences from the center of are mixed, the output result in which the characters are beautifully arranged can be obtained.

According to the document output device of the second aspect of the present invention, the coordinate position serving as the placement reference is calculated only when the character is a predetermined specific character, and the character image data of the specific character is output. Since it is placed at the reference position in the vertical direction on the image data, it can be limited so that special placement processing is performed only for specific characters. Characters whose relative positions with respect to the baseline are unified and those which are not unified. Even in a document in which characters are mixed, an output result in which characters are beautifully arranged can be obtained.

Further, according to the document output apparatus of the third aspect of the invention, the plurality of reference positions are stored in the second storage means, and the typeface to be used, the character size, the combination of the typeface and the character size, or line feed. Since one is selected from the plurality of reference positions based on the width and appropriate processing is performed, more detailed character placement can be performed according to the typeface, character size, combination of typeface and character size, or line feed width. .

Furthermore, according to the document output apparatus of the present invention, a plurality of specific character groups for specifying a character are stored, and the typeface or typeface and character size to be used are selected from the plurality of specific character groups. Since one specific character group is selected based on the combination, it is possible to perform the above-described arrangement processing for each of the specific characters that are more finely specified according to the combination of plural typefaces and the character size thereof. It is possible to arrange various characters.

According to the document output apparatus of the present invention, a plurality of specific characters are stored in the third storage means,
Since the specific character is registered or deleted in the third storage means by the setting means, a desired character can be added to or deleted from the specific character, and the preference of the user of the device can be reflected in the character arrangement.

Further, according to the document output apparatus of the present invention, since the calculating means obtains the coordinate position of a predetermined ratio of the maximum value and the minimum value of the character image data, special information is added to the character data. Instead, an appropriate character reference position can be calculated.

According to the document output apparatus of the invention of claim 7, by using the kana and kanji as the specific characters, the output result in which the characters are beautifully arranged is obtained even in a document in which Japanese and Western texts are mixed. be able to.
