Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus including a character font creating system which can be applied to a typical word processor of a document creating apparatus, a personal computer having Windows installed therein, an output device such as a printer, or the like. is there.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Laid-Open No. 4-340590 discloses a document creating apparatus including a character placement system, a dot data conversion apparatus, a bitmap print buffer and a character font generation system having a printer. This document describes a system that can reduce font data by dividing each into parts and generating font images by combining them.

The above-mentioned conventional document creating apparatus has a structure as shown in FIG. 9 when generalized, and if a character code is given,
It targets the basic part of the font generation system that outputs a font image (dot data), and is roughly divided into three parts. That is, a font data storage unit 11 (corresponding to the part placement device 11 in the above publication), a font image generation unit that generates a font image based on the font data (dot data conversion device 1 in the above publication).
2)), which is an interface portion with the outside (corresponding to a portion that performs an interface for outputting data from the dot data conversion device 12 to the printer 14 via the bitmap buffer 13 in the above publication, Currently, the output destination is not limited to the printer, but many devices that can pass a font image via a bitmap).

In the conventional font generation system, in response to a font image generation request from the outside (not described in the above publication), various kinds of font images such as part information and part combination information are generated from the font data storage unit 11. Retrieve information. The extracted information is expanded into dot data by the font image generation unit 12, and is transferred as a font image from the interface unit 13 to the external device.

In a system such as an outline font in a Japanese word processor or the like, a method of expanding font data into dot data, that is, a method of generating a font image is based on a manufacturer's original method for providing these, and in most cases, it is not disclosed. Therefore, it is not possible to personally add or customize font data. In most of these font generation systems, the addition of font data is performed on the character type (for example, a font such as Mincho or Gosic) instead of the character unit.

Conventionally, in such a case, the manufacturer will customize the utility with a utility for making these changes. However, such a utility is rarely provided, and even if it is provided, the specification is different for each manufacturer. In a system, such as Windows, in which a plurality of font generation systems that function according to the manufacturer's unique specifications can exist, the customized information cannot be centrally managed. Also,
In some cases, the scope of customization is limited to adding new characters (creating external characters), and in such a case, the original font image cannot be customized.

[0007]

In the conventional font generating system in the character generating apparatus, the only means to change the font image is to replace the font data. However, font data can usually be created only by the manufacturer who provides the font generation system, and the user cannot create it. However, it may support this for external characters. But Windows
In a system having a plurality of font generation systems such as s, the font image is generated based on the specifications unique to each maker, and therefore the font image cannot be customized by a common method.

[0008] Further, as described above, customization on a character-by-character basis is impossible except for special cases such as external characters. Therefore, it is not possible to accept a request to make the character portion thicker or thinner, or to change the character such as how to splash a certain character.

In the normal font generation system, only external characters can be customized on a character-by-character basis (provided that this is also supported). Therefore, when it is necessary to add a unique character code to a portion other than the external character area, it is necessary to perform processing in a place different from the conventional font generation system, such as newly creating a font generation system.

Further, since one font image corresponding to one character code is provided, it is impossible to create a combined character by combining one character code with a plurality of characters. Furthermore, there are some that support the replacement of character codes, such as the replacement of old and new JIS codes.
The characters specified by the manufacturer are only replaced by the specified switch, and individual characters cannot be replaced.

[0011]

[Means for Solving the Problems] An input unit including a keyboard, a document processing unit for documenting input data, an output unit for outputting documented data, and a data processing unit for outputting documented data. When a document creation apparatus having a plurality of font generation systems that output a font image of a character when given a character code, a font data storage unit that stores font data for creating a font image, a font from the font data An original font generation system that consists of a font image generator that creates an image, an interface that outputs the generated font image to the outside in response to a code request from the outside, and customized data for creating a customized font image. Customized data storage that stores A customized font image generation unit that creates a font image from the customized data, and a customized font generation system unit that includes an interface unit that externally outputs the customized font image generated in response to a code request from the outside. It is characterized by becoming.

In the document creating apparatus having the above-mentioned configuration, [code] data of a character to be customized, [arrangement] data for providing a character arrangement, and [difference] data for correcting a font image are defined as customization data. Thus, the font image output by the original font generation system unit is changed.

In the document creating apparatus for changing the font image, a new character is defined by defining [difference] data indicating the font image itself as customization data for a character code that cannot be created by the original font creating system unit. It is characterized by adding.

In the document creating apparatus having the above configuration, [code] data for referring to the original font image, [arrangement] data for specifying the arrangement of characters, and [difference] data for correcting the font image are defined as the customization data. Thus, the font image output by the original font generation system unit is combined to create a combined character.

In the document creating apparatus having the above configuration, the character code of the change destination is [code] as the customized data.
By defining it as data, the character code is changed to a code different from that of the original font generation system section.

[0016]

In the conventional font generating system, the font generating system section of the conventional document generating apparatus can only change the font image by replacing the font data or adding the external character. But Wi
In a system section that can have a plurality of font generation systems such as Windows, these methods are different in each font generation system, and thus customized data cannot be centrally managed. The customization / font generation system part of this device introduces the customization system for the most basic part of the font generation system, which outputs the corresponding font image when a character code is requested. This can be done without changing each font generation system or knowing the details of the font data that the font generation system has.

Further, as described above, it becomes possible to correct the font image for an arbitrary character code other than the external character, which is impossible with the conventional font generation system. Also, as mentioned above, the request to add a character code in addition to the external character area is to create new font data with the conventional font generation system, but with the introduction of the customized font system, it is the same as adding external characters. Character code can be added.

Further, as described above, although it is not possible to combine font images with the conventional font generation system, the customized font system can refer to the original font generation system as many times as necessary to obtain the font image. , Kumimoji can also be generated.

Furthermore, as described above, although the conventional font generation system supports the exchange of the character codes to some extent, it is only a fixed rule. Since the customized font system can make the requested code and the originally requested code different character codes, the character codes can be arbitrarily exchanged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A document creating apparatus including a font creating system according to the present invention will be described below with reference to the drawings. As shown in FIG. 1, the outline of the configuration of this device is as follows: an input unit 1 including a keyboard for receiving an input from a user, a document processing unit 2 for documenting data input from the input unit 1, and a document processing for this document processing. Display the data documented in part 2,
It is composed of an output unit 3 for outputting by a printer and the like, and a plurality of font generation system units 4 for outputting a font image of the character when given a character code in the data for outputting documented data.

With the above-mentioned configuration, in the present apparatus according to claim 1, as shown in FIG. 2, customized font generation is performed for the original font generation system unit 4A having two types of font systems. A case where the system unit 4B is introduced will be described. The configuration of each claim can be realized by applying the customized data of the customized font generation system unit 4B to the font image generation unit of the original font generation system unit 4A, which will be described below. The difference between the claims is what kind of data is used as the customization information.

In the original font generation system section 4A, a plurality of font data 11a, 11
.., a font image generation unit 12 for generating a font image based on the font data, and an interface unit 13 for interfacing with the outside.

In the customized font generation system section 4B, a customized data storage section 21 for storing data in document units, and a customized image generation section 2 for developing and generating an image based on the customized data.
2. An interface with the outside, an original font generation system section, and an interface section 23 for storing the created image in the output buffer. The customization data storage unit 21 stores three types of customization data such as code data, difference data, and arrangement data shown in FIG. 3 in a data format as shown in FIG.

The system table of FIG. 4 (a) lists the original font generation systems recognized by the customized font generation system.
You can check which font generation system the character code requested from the outside is. From here, the address to the code table assigned to each system can be obtained.

The code table of FIG. 4 (b) is for recognizing the existence of the customized data of FIG. 4 (c) assigned to a certain original font generation system, and is customized to the character code requested from the outside. You can check if the data is assigned. From here, the address to the customized data assigned to each code can be obtained. By referring to these data, the customized data for the character code requested from the outside is extracted. Each claim is realized by a combination of this customized data.

The customized image generator 22 is
When the character code request is received from the interface section 23, the customization data stored in the customization data storage section 21 is referred to and the processing is performed. If necessary, the original font generation system unit 4A recognized by the customization system is called via the interface unit 23 to obtain a font image.

The interface section 23 has an output buffer for storing a font image, and interfaces with the outside and the customization system. When a request by a character code from the outside is received, the request is passed to the customized image generation unit 22, and the font image returned from the request is returned to the outside via the output buffer. Further, if there is a request from the customized image generation unit 22, the font image is requested to the original font generation system.

The font image generator 12 is shown in FIG.
The customized data is processed according to the processing flow shown in. When an external request is made, the system table is used to check which original font generation system the request was made to (step 5).
1). If the system is not registered, the customizing process is not performed and the normal process is performed (step 5A). If it is a registered system, the address of the code table is obtained (step 52).

It is checked by referring to the code table whether or not the customized data is assigned to the requested character (step 53). If it is assigned, the address of the customized data is obtained (step 54).

The existence of the [code] data is checked from the customized data (step 55), and if there is, a request for a font image is made to the original font generation system (step 56). The obtained font image is arranged at an arbitrary position in the output buffer according to the following [arrangement] data if there is any (step 57), and if not, it is placed in the localization value of the output buffer (in most cases, the center).
(Step 58). The above processing is repeated until there is no [code] data.

When the processing of the [code] data is completed, the [difference] data is checked, and if there is, the [difference] data is expanded (step 59). The [difference] data is black or white data, and the defined [difference] data is sequentially expanded and overlaid on the output buffer. The above processing is performed for the number of [difference] data. Taking the “figure” of the kanji shown in FIG. 6 as an example of the above-mentioned [difference] data generation method, when the thin line image 62 in the upper right portion 61 of the original font image is changed to the thick line image 63 , The outline data of the difference 64a to be added to the original font image is black data (black-painted portion), and conversely the difference 64b to be the portion to be deleted
Outline data becomes white data (white painted portion).
The customized data of the output buffer completed by the above processing is output to the requested external device 14 (step 5B).

In the present invention, the customized font generation system unit 4B is completely independent of the original font generation system unit 4A regarding the format of the font data of the original and the method of generating the font image from the font data by the font image generation unit. Since it is possible to consider that it has been done, it is not specified. Further, as the [difference] data, the data as shown in FIG. 3 is stored, but the outline data description portion of the difference data necessary for the actual font image generation is not specified here. This may be the same format as any of the original font generation systems, or it may be a completely different format.
The method of generating a font image from this data also does not depend on the original font system and is not specified here either.

In the apparatus according to the second aspect, the customization data is composed of [code] data to be customized, [arrangement] data that specifies the arrangement of characters, and [difference] data that corrects the font image. To be done. When this character code is requested from the external device 14, the customized driver refers to the original font image with the [code] data to obtain the original dot data. The obtained font image is arranged by the [arrangement] data, and finally the [difference] data is expanded and superimposed on the original image to obtain a customized font image.

As a specific example of changing the font image, consider changing the image of the character "FIG." Shown in FIG. Image 6 for the upper right part 61 of the text
If only the changed portion is extracted from the thick-lined portion image 63 that has undergone the second correction, difference images 64a and 64 are obtained.
b can be obtained. Therefore, the customized data is created as follows.

[Code], character code of “figure”, 100 (ratio to requested size), 0 (no attribute) [difference], 2 (number of difference data) black data, n1 (number of data of difference a), difference Data of a ... White data, n2 (data number of difference b), data of difference b ... There is no [arrangement] data. In this case, the [arrangement] data slightly shifts the original font image to correct the image. This is not necessary in this example because it is used for the purpose. This data is processed as follows. First, the [code] data is used to obtain the original font image from the original font driver and place it in the output buffer. The original font image can be customized by expanding the [difference] data and overlaying it on the output buffer.

According to the third aspect of the present invention, the customized data is composed of the data of the font image ([difference] data of black data only). When this character code is requested from the outside, the customized driver does not refer to the font image of the character to be added from the original font generation system unit 4A, and uses all the [difference] data as the font image developed by the customized driver. Therefore, the [difference] data for newly expanding the font image is only the black data because it is only the added portion.

As a specific example of adding a font image, consider adding the symbol 71 shown in FIG. 7 to the font generation system. In this case, the font generation system does not have an image for the symbol 71, so the difference data indicates the entire symbol 71. Customized data is created as follows.

[Difference] 4 (Number of Difference Data) Black Data, n1 (Number of Data of Difference 72a), Data of Difference 72a ... Black Data, n2 (Number of Data of Difference 72b), Data of Difference 72b ... :::: Black Data, n4 (number of data of difference 72d), data of difference 72d ... Since the original font generation system is not referenced, the [code] and [arrangement] data are not defined.

This data is processed as follows. Since there is only the [difference] data, a new font image is generated by expanding the [difference] data to the output buffer where nothing is placed.

In the apparatus according to the fourth aspect, the customized data is the [code] data of characters required to form a combined character, the [arrangement] data that specifies the arrangement of the characters, and the generated image is modified. [Difference] data. When this character code is specified from the external device 14, the customized driver refers to the original font generation system section 14A in the [code] data as many times as necessary to obtain the font image, and then to the position specified in the [arrangement] data. Overlay the font image. At this time, since the shape of the character may be deteriorated by simple superposition, the [difference] data is referred to and expanded, and the image is further corrected and output.

As a concrete example of creating a new character,
When the font generation system shown in FIG. 8 has the character 82 “car” but not the character 81 “roar”, consider adding the character 81 “roar”. In this case, the font image of "car" may be arranged in the font generation system unit 4A at different positions by changing the size. Therefore, the customized data is created as follows.

[Code], [Car] character code, 70
(Ratio to required size), 0 (no attribute) [Arrangement], 10, 5 ... character code of part a [code], [car], 50 (ratio to required size), 1 (no attribute) [arrangement], 10, 45 ... parts b [code], character code of [car], 50 (ratio to required size), 0 (no attribute) [arrangement], 45, 45 ... parts c If is displayed, define [difference] data to further correct the font image. This data is processed as follows. A font image is obtained from the original font system by [Code] data and [Arrangement] data and arranged at an arbitrary position in the output buffer. By repeating this for the code data and the [arrangement] data, a combined character in which the original font image is combined is generated in the output buffer.

According to the fifth aspect of the present invention, the customized data has [code] data of a character to be replaced as code data. When this character code is requested from the external device 14, the customized driver requests the character code to be replaced from the original font driver and outputs the font image.

As an example of exchanging the character code, consider exchanging the character code a and the character code b. Since the other character code can be defined in the code data as customized data for each character code,
It is defined as follows. -Customized data of character code a [code], code of character b-Customized data of character code b [code], code of character a This data is processed as follows. Since it is only [code] data, the original font image specified by [code] data is stored as is in the output buffer. If the requested character code is a, the output font image is b, and if the requested character code is b, the output font image is a. That is, the codes of both parties are exchanged.

[0045]

Since the document creating apparatus according to the present invention is constructed as described above, in the present apparatus according to claim 1, the customized font creation system is unique to the supplier such as original data and font creation method. Since it does not depend on the specifications of, the font image can be customized even if these specifications are not published. Further, since the customization system is completely independent of the original font generation system, the customization information can be centrally managed in a system capable of managing a plurality of font generation systems (for example, Windows). This is because, for example, when installing Windows on a device with a special character code system,
Any of the font generation systems available above can be used to support this special character.

According to the second aspect of the present invention, the font image can be changed character by character. For example, it is possible to make thicker / thinner only a part of a character, to emphasize the splash / spray, and to make the number of strokes of the character white.

In the present apparatus of claim 3, characters can be added uniquely in any font generation system. There is no conventional control of only external characters, and new characters can be added to any character code. For example, various symbols are assigned to the front of the JIS code, but it is also possible to assign a symbol that the user personally frequently uses, instead of a character code that is rarely used.

According to the present apparatus of claim 4, a new character can be created by combining the font images of the conventional font creating system. For example, several number images can be overlapped to form a consecutive number image (“1” “2” → “12”). The character code that can be created can be assigned to an arbitrary code as in the third aspect.

In the present apparatus according to claim 5, the character code can be exchanged arbitrarily, which can be changed only by a certain rule, even though the conventional font generation system can. For example, in the JIS old and new fonts, the old and new fonts are replaced only for the necessary characters. It is possible to change the code, such as changing the number to a different type (one to one).
