Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a word processor capable of performing editing including changing attributes of document elements such as colors and character fonts.

[0002]

2. Description of the Related Art Recent technological advances have made it possible to easily create a document in a word processor or a document editing editor on a workstation. Recently, its functions have been further enhanced and it has become possible to create color documents. By outputting it to a color printer, a color document can be easily created.

At this time, when a color is specified in a document editing apparatus such as a word processor, it is usual to specify an absolute color for a certain component in a document, and it is generally used. Method ("designating an absolute color" here means directly designating a certain color). For example, in a certain document, "title" color is "blue" and "author name" is "red". For example, "red" and "blue" are attributes of the characters indicating "title" or "author name". Directly specify a color such as ". For example, when you want to color a part of a character string of a document in the document processing device J-Star of Fuji Xerox Co., Ltd., select the character string to be colored, open the property sheet, and then there. A method of designating a color to be designated in a column is used (Fuji Xerox Co., Ltd., "Global View Color Workstation Addition Manual"). In the case of this example, it is a character, but in the case of a figure, it is exactly the same. Select the figure element to be colored, open its property sheet, and directly specify the color.
In other document processing devices, there is a difference whether or not it is specified using the method called the property sheet.
There is no change that graphic elements have absolute color values as attributes.

On the other hand, in general, similar colors are often used for coloring documents. For example, in a bar graph in the case of a business document as shown in FIG. 12, each bar of a related group of bar graphs is often represented by coloring with a shade such as “blue”. In addition, the chapter titles are unified into blue, and the titles that represent the finer parts of the chapters, such as clauses and paragraphs, are expressed in light blue in order of density. In other words, what is logically related is represented by the shade of color.

[0005]

When creating such a document, it is not possible to perform editing that changes the color image, for example, to make elements that were expressed in shades of blue shades of green. , It seems to be done frequently. However, if such an editing operation is attempted by a conventional word processor or the like, the light and shade information is lost as the color information is changed although the light and shade information does not have to be changed. There was a problem that you had to manually re-enter the shade information for all the element colors.
A similar problem was that attributes other than color, such as attributes such as font type and size, also appeared. Then, this invention makes it a subject to solve the problem. That is, an object of the present invention is to make it possible to easily change the attribute of a document constituent element when editing a document processing apparatus.

[0006]

The present invention (Claim 1) includes:
Document input means for inputting a document (11 in FIG. 1, 9 in FIG. 9)
1) and attribute holding means (122 in FIG. 1, FIG. 9 in FIG. 1) for holding the attributes for the constituent elements of the document input by the document input means as a relationship with the attributes for the other constituent elements.
922) and document constituent element processing means (13 in FIG. 1, 93 in FIG. 9) for changing the constituent elements of the corresponding document based on the attribute held by the attribute holding means. Is.

In one aspect of the present invention (claim 2), in the document processing apparatus, an attribute of a component held by the attribute holding means (for example, a component whose identifier in FIG. 2A is B) Other components (for example,
An attribute (for example, relative (a) in FIG. 2A) indicating the constituent element A in FIG. 2A, a value of a specific attribute of the reference constituent element that is the other constituent element to be referred (for example, Figure 2
The relative value [0,5,10] of the color of component A in (a) (for example, the relative value [0,0,
−1]), and the type of relationship (complementary color, shading, etc.).

In another aspect of the present invention (claim 3), the attribute indicating the reference constituent element is an expression representing a relation, for example, the immediately preceding constituent element as shown in FIG.
The previous component, or the parent for a tree-structured document,
It is characterized by being specified by an expression indicating the relationship of the younger brother.

[0009]

According to the present invention, when the attributes such as the color and the font size of the constituent element are designated, the attribute can be designated by the relative value to other constituent elements, and the above-mentioned problems are solved. Is what you are trying to do. That is, in the present invention (Claim 1), the attribute for the constituent element of the document is designated as the relationship of the attribute for other constituent elements in addition to the conventional designation by the absolute value, and is held by the attribute holding means. It The document component processing means determines the attribute of the document component based on the attribute held by the attribute holding means. As an attribute of a constituent element, in one aspect (claim 2) of the present invention, which constituent element is referred to by the constituent element, a relative value with respect to an attribute value of the reference constituent element, and an attribute of the reference constituent element Information such as whether there is a relationship is included. For example, when specifying the color value of a component, in addition to the conventional absolute value specification, which component is referred to, the relative value with the color of the component, and the relationship with that color (complementary color , Shade, etc.) should be specified.

By doing so, when a component having a relative color relationship (or font size relationship) with a certain component as a reference is changed when the image of the entire document is changed. It is not necessary to change the attributes such as individual color and font size, and you can change the overall color and font by changing the attribute value of the component for which the basic color and font size attributes are specified. It becomes possible to change attributes such as font size,
The efficiency of the user's color editing work can be improved. In addition, in recent years Open Document Architec
Structured documents such as true are drawing attention, but when this method is applied to structured documents, the effect is remarkable.
That is, in the structured document, the logical relationship between the documents is described in a format called a logical structure. It can be used to make various designations according to the logical structure.

【Example】

(Embodiment 1) In this embodiment, a conventional document processing apparatus for absolute color designation is newly provided with a color designation function based on relative colors. FIG. 1 shows a block diagram of this embodiment.

<Structure of Embodiment 1> In this embodiment, an input unit 11 for inputting a document is relative to a relative color designation unit 112, and a document data holding unit 12 for holding contents / attributes of constituent elements of the document. A color holding unit 122 is added, and a color calculation unit 13 for calculating a color from a relative color when displaying on a visualization unit 19 such as a printer or a display is provided.

The relative color holding unit 122 is a component holding unit 1.
The relative color can be held by the same method as other attributes (for example, character size and font type) in the document held in 21. Generally, these attributes are also combined to store the relative color. It will be 12. The relative color designation section 112 is also designated in the same manner as other document attributes designated by the content / attribute designation section 111.

When outputting the layout result of the document to the visualization unit 19, the color calculation unit 13 refers to the absolute and relative designated color values designated for each component, and refers to the color of the component. Has the role of calculating In addition, the relative color holding unit 122
The component to be referred to (referred to as a reference component) is specified in, but if it is specified using an expression, the color calculation unit 13 calls the reference component determination unit 14 to make the determination. To do.

Further, the relative color designation section 112 can designate a relative relation, but this can be defined by the user in addition to the relation held in advance by the system. The relative relationship holding unit 18 and the relative relationship designating unit 17 are used for that purpose. That is, the user defines the relative relationship by the relative relationship designating unit 17, and the defined relative relationship is held in the relative relationship holding unit 18. The relative relation held in the relative relation holding unit 18 is referred to when the relative color designation unit 112 designates the relative relation and when the color calculation unit 13 has to calculate the color.

The other allocating unit 15 and the visualizing unit 19 can be constructed by conventional techniques. In other words, in a document processing device that can handle conventional colors, when displaying colors, it is now possible to specify relative colors where only absolute colors were specified for individual components, and that value can be used to specify individual colors. Since the only difference is that the determination is made, the peripheral components can be configured without changing the prior art.

<Relative Color Holding Unit 122> FIGS. 2A and 2B show examples of data held in the component holding unit 121 and the relative color holding unit 122 in FIGS. ) Shows an image of the document represented by the contents of the holding unit. In the case of this example, each component has attributes as shown in each item of the component holding unit 121. In the example given here, it is possible to color each component, so it is not possible to color only a part of the character string, but this is for the sake of simplicity of explanation. Problem is not a problem.

The component holding unit 121 holds, for each component, the identifier of the component, the type of the content, the content, and the color. Absolute or relative values can be specified for the color specification. When the color value is "absolute", it means that the constituent element is represented by the specified color itself.
For example, the constituent element A is a text having a content of “Chapter 2 system”, and RGB = [0, 5, 10]
It means that the color (blue-green with a strong blue tint) is absolutely specified. On the other hand, in the case of relative, it means that the relative color designated in the relative color holding unit 122 is referred to, and for example, the color of the component B refers to the data of a in the relative color holding unit 122. is doing. In the conventional technique, only the absolute value mentioned here can be expressed. The essential feature of the present invention is that it can be designated relatively.

The color attribute in this example is expressed in RGB format, and each value takes a value from 0 to 10, and the larger the value is, the stronger the brightness of the color is (the RGB method is generally used for display on a workstation or the like for display). R is red, G is green, and B is blue.) In order to hold such color attributes inside, YMC (K), LAB, XYZ, hue
It goes without saying that there are various methods such as saturation and lightness, and they can be mutually converted, so that the color expression method itself does not represent the essence of the present invention.

In the relative color holding unit 122, for each relative color data, its identifier, reference component, relative relationship,
Holds a relative value. The reference constituent element represents which constituent element the relative value is specified based on the color of the constituent element. The relative relationship specifies the relationship between the color of the reference component and the color that the relative color is about to specify. In the case of this example, "difference" and "complementary color" are defined. The "difference" represents a simple difference from the value designated as the relative value, and the "complementary color" is a value obtained by subtracting each RGB value of the color of the reference constituent element from [10, 10, 10] (here "Complementary color" does not mean a complementary color in the strict sense of color engineering). In this example, only the above two relationships are expressed, but other relationships can also be used by defining (using the relative relationship holding unit 18 described later).

<Relative Color Designating Section 112> Relative Color Designating Section 11
An example of the interface No. 2 is shown in FIG. This is a property sheet for specifying text attributes. In the case of this example, not only the relative color can be specified, but also the font and size of the character and the absolute color can be specified at the same time. That is, the relative color designating section 112 is realized by incorporating it into the conventional content / attribute designating section 111. A portion surrounded by a frame in the figure is a portion selected by the user. Only the color designation portion will be described below.

The color is selected as either absolute or relative. The upper part of FIG. 4 shows the case where the attribute is designated absolutely, and the lower part shows the case where the relative is selected. The attributes that can be specified change depending on the absolute / relative selection, and the display on the property sheet also changes accordingly.

In the case of absolute designation, the designation of color is designated by name or by parameter. In the case of this example, the method of designating by the color name is selected, and the color "blue-green" is designated.

In the case of relative, the identifier of the reference component, the relative relationship, and the relative value are designated. In the case of this example, values of A, difference, and [0, 0, -1] are designated. The items that can be selected by the relative relationship can specify not only the relationship that the system has in advance but also the relationship defined by the user in the relative relationship holding unit 18 described later. In the case of this example, "difference, complementary color" is a relationship that the system has, and "composite 1" is a relative relationship defined by the user.

When the color is designated by relative, the relative value is not designated directly but the absolute color is designated, and the relative value is calculated in reverse from the relative relationship between the reference component and the designated absolute color value. You may do it. This is effective when it is desired to specify the color relatively, but the color of the component is directly specified. For example, assume that there is a component X that refers to a component Z that also has the color RGB = [0,5,10]. I want to keep the color attribute of that component relative to Z, but there is a certain color RGB in X = [0,8,
10]. In that case, if the relative relationship is a difference, the relative color calculation unit 16 may be called, [0,3,0], which is the difference, may be calculated as a relative value, and stored in the relative color holding unit 122. With respect to the relative color calculation unit 16, since the processing is simple, no further description will be given.

<Relative Relationship Holding Unit 18> Relative Relationship Holding Unit 1
8 holds the relative relationship defined by the user. It is a mechanism for defining a relationship that the user often uses in addition to the relationship that the system has in advance (“difference” and “complementary color” in this embodiment). The relative relationship means what kind of relationship it has with the component to which it refers when designating a relative color to the component.

FIG. 5 shows an example of data held in the relative relationship holding section 18. The relative relationship holding unit 18 holds the relative relationship identifier and its definition. In this example, three relations of "reddish, darkened, composite 1" are defined. The definition part is defined by a programming language-like calculation formula.

= In the definition part is a symbol meaning substitution, and variables R, G and B on the left side are finally converted to R.
Used as a GB value. The RGB values of the reference constituent elements are respectively substituted into R, G, B on the right side, and r, g, b
The value specified by the relative value is assigned to. Therefore, the user can define the relationship using the RGB value of the constituent element and the RGB value designated as the relative value.

For example, "reddish" in FIG. 5 refers to the values of the reference constituent elements as they are for G and B, and only R is +1.
However, it means increasing redness. "Darkening" is R,
This means that the values of G and B are halved to darken the color. “Composite 1” means subtracting the parameter designated as the relative value from the value of the reference component. By the way, "difference" and "complementary color" are defined in the system, and when expressed by this definition formula, the difference: R = R + r; G = G + g; B = B +
b; Complementary colors: R = 10-R; G = 10-G; B =
10-B;

<Relative Relationship Designating Section 17> Relative Relationship Designating Section 1
7 is used for the user to specify the relative relationship. An example is shown in FIG. As shown in the figure, it comprises a portion for inputting a relation name and a definition formula to be defined, and a list of relations held by the relative relation holding unit 18.

<Color Calculation Unit 13> The color calculation unit 13 is used to calculate an absolute color from the value when the color of the constituent element is designated by relative. The calculation method is as follows.

(Step 0) If the color of the constituent element is absolutely specified, it is set as the absolute color. Otherwise,
The processing from step 1 onward is performed.

(Step 1) The data of the specified identifier held in the relative color holding unit 122 is referred to, and the reference component, the relative relationship, and the value of the relative value are fetched.

(Step 2) The color value specified in the reference component is fetched. At this time, if the reference component is designated by the relative color, the relative color calculation unit 16 is recursively called to obtain the absolute color of the component. The obtained color values of the reference constituent elements are SR, SG, and SB.

(Step 3) If the relative relationship is "difference", the following processing is performed. If not, go to step 4. Each RGB value specified as a relative value and step 2
The RGB values of the reference constituent elements obtained in step 1 are added together, and this is taken as the absolute color of the constituent elements. That is, if the values specified as the relative values are r, g, and b, then R = SR +
RGB obtained by calculating r, G = SG + g, and B = SB + b is the absolute color of the constituent element. Go to step 6.

(Step 4) If the relative relationship is "complementary color", the following processing is performed. If not, go to step 5. In this case, the value specified as the relative value is ignored, the following calculation is performed, the obtained RGB values are set as the absolute values of the constituent elements, and the process proceeds to step 6. R = 10 − SR, G = 10 − SG, B = 10 −
SB

(Step 5) Since the relative relationship that has not been processed so far is supposed to be the relative relationship defined by the user, the relative relationship holding unit 18 is referred to and the definition of the specified relative relationship is fetched. . According to that definition, the absolute color is calculated and used as the absolute color of the component.

(Step 6) It is checked whether the obtained RGB values of the absolute color are within the defined range (whether each value is within the range of 0 to 10), and if there is a deviating value, correction is made. To do. Specifically, it becomes 0 when it becomes a negative value.
When it exceeds 10, it is corrected to 10.

Description will be made with reference to the examples of FIGS. Example 1) Obtaining the color of the component B Referring to the data part of the color of the component B, the relative color a is specified. Therefore, a of the relative color holding unit 122 is referred to. Since A is designated as the reference component, the color of A is referenced and the absolute color [0, 5, 10] is fetched. a
Is a difference, the relative value of [0,0, -1]
And [0,5,10] are added to obtain [0,5,9], which is the absolute color of the constituent element B.

Example 2) Obtaining the Color of Component R Referring to the data section of the color of component R, the relative color d is specified. Therefore, reference is made to d of the relative color holding unit 122. Since P is specified as the reference component, the color of P is referenced and the absolute color [0, 7, 0] is fetched. Although the composite 1 is specified as the relative relationship of a, this is a user-defined relative relationship, so the relative relationship holding unit 18 is referred to. Assuming the relative relationship of FIG.
R−r; G = G−g; B = B−b; ”. When this definition formula is evaluated, the relative value is [0,
4,0], and thus R = 0-0; G = 7-
4; B = 0-0; and [0, 3, 0],
This is the absolute color of component B. In addition, when the relative relationship that the system has is only "difference" and no user definition is performed, the relative relationship is only "difference", and the relative color holding unit 122 does not need to hold the relative relationship. .

(Second Embodiment) An embodiment in which a reference constituent element is designated by a formula In the first embodiment, the relative color holding unit 122 holds the reference constituent element as described above. Its content was an identifier for a component. When directly referring to the identifier of a certain component, the reference component often disappears when the document is edited, or when the component with the specified relative color is copied to another document, the reference destination often disappears. Occurs in. In that case, a special process such as outputting a message to the user indicating that the color cannot be determined and notifying the user must be performed.

Therefore, in the second embodiment, the reference destination is not designated directly by the component but indirectly designated by using an expression. That is, in the second embodiment, designation is made as "immediately preceding component" or "immediately following component". By doing so, the phenomenon that there is no reference destination can be reduced as much as possible, and the reusability that an element of one document is used for another document can be improved.

Specifically, the reference constituent element of the relative color holding unit 122 may be designated by using an expression. FIG. 7 shows an example thereof. In FIG. 7A, the reference constituent elements of the relative color holding unit 122 of FIG. 2 are rewritten by using equations. The meaning of the formula is as shown in FIG. The information held in the relative color holding unit 122 of FIG. 7 is the same as that of the information shown in FIG.
Even if it is replaced with that of the relative color holding unit 122, the meaning is completely the same. For example, although b in FIG. 7 is referred to from C in FIG. 2, prev (pr
Since ev (self) means "one before one before oneself", it means the constituent element A after all. Others are the same.

<Reference Component Determining Unit 14> The reference component determining unit 14 evaluates the formula and determines the reference component when the reference component is specified by the formula when determining the relative color. And is called from the color calculation unit 13.

Other configurations are the same as those of the first embodiment.

(Example 3) Example in which the present invention is applied to a structured document Open Document Architecture
In a so-called structured document such as, unlike a general word processor, in which constituent elements are only ordered in one direction, they are more complicatedly structured like a tree structure. In that case, it is expected that advanced designation can be performed by designating the reference destination.

An example thereof is shown in FIG. FIG. 8 shows an example in which only the first page of FIG. 3 and the first half of the component holding unit of FIG. 2 are represented by a structured document. 8B is called a logical structure,
The content is structured and is represented by a tree structure.
This consists of the title of Chapter 2 and Section 2.1.
Section 1 expresses that it consists of the title and section 2.1.1. The portion indicated by the dotted line frame in this tree structure diagram corresponds to the constituent element of the constituent element holding unit in FIG.

When the constituent elements are structured in a tree structure, it is possible to diversify the way of specifying the reference constituent elements by the expression. For example, in the case of unstructured, there was no choice but to refer in the form of a component before or after a certain component, but in the case of a tree structure, "the sibling component of the most elder brother" Or, it can be designated as "a component of a parent's parent's child (corresponding to his uncle) who is the youngest brother".

In the relative color holding unit of FIG. 8C, the reference component is designated by such an expression. In the relative color holding unit, a “child (child (superior
(Superior (superior (sel
f))))) "means" children of the parent's parent's parents' children ", which means A in component B and B in C. The meaning of the equation is shown in FIG.

The other configurations are the same as those of the first embodiment.

(Fourth Embodiment) In the fourth embodiment, a value can be designated relative to a font attribute in a conventional document processing apparatus. This is basically obtained by replacing the color information with the font size information in the above-described first embodiment.

Generally, the font size is changed between the title and the body of a document. In that case, the title uses a large size font and the body uses a smaller font. The ratios are usually fixed, and sizes that are too far apart are rarely used. For example, if the body text is 10 points, it is usual to use 12 points for section titles and 14 points for chapter titles, and use a large size of 18 points or 20 points for titles. Is rare. Therefore, when the character size of the text is changed, the size of the title is reduced accordingly. In such a case, the conventional document processing apparatus has to change the font size of the title part together with the size of the body.

The fourth embodiment can solve such a problem. In other words, if you refer to the font size of the text and specify the value of another title relative to it, simply changing the font size of the text will increase the font size of the title. . Conversely, the font size of the text may refer to the title. In this embodiment, the font size is taken as the target of the attribute, but it is applicable to general attributes such as margins of other paragraphs that are specified numerically or internally held.

FIG. 9 is a diagram showing the structure of the fourth embodiment. In the fourth embodiment, as in the first embodiment, a relative value designation unit 912 is provided in the input unit 91 for inputting a document, and a relative value storage unit 92 is provided in the document data holding unit 92 for holding the contents / attributes of the components of the document. In addition to the unit 922, an absolute value calculation unit 93 for calculating the absolute value from the relative value when the visible image such as a printer or a display is displayed on the unit 95 is provided.

<Relative Value Holding Unit 922> FIG. 10 shows an example of the component holding unit and the relative value holding unit, and FIG. 11A shows an image of the document represented by the contents of the holding unit of FIG. In the case of this example, each component is assumed to have an attribute as shown in each item of the component holding unit 921.

The component holding unit 921 holds, for each component, the identifier of the component, the type of the content, the content, and the style. The style is also stored in the component holding unit 921, and the style includes the font size, font type,
The face can be specified. Then, the style is referenced by a plurality of components. For example, the style S4 in FIG. 10B is a style for the text, which is shared by a plurality of texts corresponding to the text.

FIG. 10B shows the contents of the style in the conventional document processing apparatus. The font sizes of the styles S1 to S4 respectively include font sizes of 14, 12, 10, and 10 in points.

FIG. 10B shows a style in which the font size can be designated relative to each other according to this embodiment. In the case of the relative designation of the font size value, the designation "relative" is designated together with the identifier of the relative value holding unit 922. For example, the font size value of the style S1 is “relative (a)”, which is the relative value holding unit (see FIG. 10).
This means that the data a in (c)) is referenced. In the conventional technique, only the absolute value mentioned here can be expressed. The essential feature of this embodiment is that it can be designated relatively.

As shown in FIG. 10C, the relative value holding unit 922 holds the identifier, the referenced element (style), and the relative value for each piece of relative value data. The reference element represents which component value the relative value is specified as. When specifying the reference element, specify the reference element. For example, in attribute a of FIG. 10C, “S4” is designated as the reference element, but this is style S.
This means that the font size value of 4 is referred to.

Since only the font size is the attribute that can be designated relative to each other, only the element identifier needs to be designated as a reference element. However, when a plurality of attributes can be designated relative to each other, reference is made here together with the reference element identifier. The attribute name to be specified can be specified. For example, when both the font size and the color can be designated relative to each other, the designations such as "S4 (font size)" and "S4 (color)" are made to distinguish them.

The relative value is the difference from the value specified by the relative element. Therefore, in the style of (b ') of FIG. 10, since the reference element of S1 is S4, 10 which is the font size of S4 is referred to and the relative value of 4 is added.
4 is equivalent to the font size of style S1 being designated.

<Relative Value Designating Unit 912> Relative Value Designating Unit 91
An example of the interface unit 2 is shown in FIG. This is a property sheet for specifying text attributes. In this example, the font, size, and face of the character can be specified. In this example, only the font size can be specified relative. The font size designation will be described below. Select whether to specify the font size relative. The upper part of FIG. 11B shows the case where the attribute is designated by absolute, and the lower part shows the case where relative is selected. The attributes that can be specified change depending on the absolute / relative selection, and the display on the property sheet also changes accordingly.
For absolute specification, specify the font size with a number. In the case of this example, 10 points are selected. If relative, specify the identifier of the reference component and the relative value. In the case of this example, the values S4 and 2 are designated.

<Absolute Value Calculation Unit 93> The absolute value calculation unit 93 is used when calculating the absolute value from the value when the font size of the component is designated by relative. The calculation method is simple, and the absolute value is obtained by referring to the font size specified in the identifier of the reference element and adding the value specified by the relative value.

The calculation method will be described in more detail below. (Step 0) If the font size specified in the style is absolutely specified, it is set to the absolute value. If not, the processes from step 1 onward are performed.

(Step 1) Referring to the data of the specified identifier held in the relative value holding unit,
Get the relative value.

(Step 2) The font size value specified in the reference element is fetched. At this time, if the reference component is designated by a relative value, the absolute value calculation unit is recursively called to obtain the absolute value of the font size of the element. Let F be the font size of the reference structuring element obtained.

(Step 3) When the value of the relative value designated in the relative value holding unit is RF, the absolute value of the font size is F + RF, and that value is the absolute value of the font size.

An example of obtaining the font size of the style S2 in the data of FIG. 10 will be described. Referring to the data section of the font size of S2, relative (b) is designated. Therefore, reference is made to b of the relative value holding unit.
Since S4 is specified as the reference element, the font size of S4 is referenced and the absolute value of 10 is fetched. The relative value of b is added to 2 and 10, and 12 is obtained, which is the font size of the style S2.
