Abstract

PROBLEM TO BE SOLVED: To provide a document information processor and a document information processing method which make distinctive the meaning of an attribute value belonging to layers as to finger information having a hierarchical structure and enable a drawing and a converting process for a graphic consisting of a combination of attribute values. SOLUTION: Given document information is interpreted and inputted by a document information input means 1 and passed to a document information managing means 2. The document information managing means 2 constitutes a subtree from the inputted input information and adds the subtree to constitute a tree structure, thereby holding hierarchical document information. Once the subtree is obtained, its contents are checked and a coordinate system giving the meaning of an attribute value regarding a distance appearing in attribute information is added corresponding to the attribute value. Consequently, coordinate conversion for the figure shape and coordinate conversion for the attribute value regarding the distance can independently be processed. A drawing information generating means 3 interprets the tree structure held in the document information managing means 2 to generate drawing information needed for drawing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing and configuring document information, and more particularly to a method for processing a coordinate system in document information. It is about.

[0002]

2. Description of the Related Art In a document creation system on a computer, processing for arranging data from another document or application software in accordance with a layout is performed. Since the data to be arranged has a structure such as a chart or graphics, the result of arranging them according to the layout is generally expressed as information having a hierarchical structure. In a system that handles hierarchical document information, it is necessary to perform processing on the entire hierarchical structure in order to unify the appearance of the entire document, and processing on a part of the hierarchical structure in order to make local changes.

A method for providing an interface for performing such processing on a graphic editing apparatus is disclosed in, for example,
There is a method disclosed in -160901. This is to specify a subset of a set of figures with a hierarchical structure to be edited independently from the whole, so that the result of processing on a certain figure is reflected in other figures included in the subset. Thus, the local processing is reflected in the hierarchical structure. In this system, for example, when it is desired to transform a plurality of figures, a group of figures to be processed is defined, a transformation process is performed on one of the groups, and the result is applied to the entire group. By performing the reflection, it is possible to realize a deformation process for a plurality of figures.

[0004] When such conversion processing is performed in units of groups, the coordinate system may be different between groups or figures. For example, when it is desired to unify the line width, the line width is set for one figure and reflected on other figures and groups in the group. At this time, since the set line width is interpreted in the coordinate system of each figure or group, for example, in a figure or group having a reduced coordinate system, the line width is reduced and thinned, and conversely, the expanded coordinate system is changed. The line width of a graphic or group having the line is enlarged and thickened.
Therefore, in the above-described system, it is necessary to set the respective line widths for figures and groups having different coordinate systems in order to unify the line widths. Therefore, the editing operation is complicated.

As described above, when dealing with graphic information having a hierarchical structure, if only attribute values having a length such as a line width are given by propagating through the hierarchical structure, the attribute values may be affected by local coordinate transformation. Received and is not interpreted correctly. This is because a coordinate system that defines the meaning of the attribute value is not specified for the attribute value representing the length.

On the other hand, consider the case where a figure is drawn by a figure drawing apparatus. For example, Adobe PostSc
When an ellipse is drawn with a constant line width using the Ript (registered trademark) language, the description is a description of the following procedure. First, an elliptical shape is specified by defining a coordinate system in which the ratio between the vertical axis and the horizontal axis of the coordinate axes is changed and giving a circular shape. Next, a line width is defined after performing a coordinate conversion for restoring the ratio between the vertical axis and the horizontal axis of the coordinate axes. Then, the drawing command is executed. Here, the line width is defined after performing the coordinate conversion for returning the ratio of the vertical axis and the horizontal axis of the coordinate axis to the original value. In the PostScript language processing system, the interpretation of the attribute value is performed when the rendering command is executed. This is because it is interpreted in the coordinate system of. Unless the ratio of the coordinate axes is restored, the line widths in the vertical axis direction and the horizontal axis direction will be different, and the line width will not be constant.

If only the line width is used, a desired figure can be drawn by performing the above-described execution procedure. However, when a plurality of attribute values related to the distance are given, all of them are interpreted in the coordinate system at the time of executing the drawing command in the PostScript language processing system. For this reason, for example, even when it is desired to specify the attribute values of the line width and the broken line pattern in independent coordinate systems, one of the attribute values may be interpreted as an unintended value.
For example, if the line width is fixed and the dashed line pattern is to be converted and used using a coordinate system obtained by converting a circle into an ellipse, a figure that satisfies both conditions cannot be drawn. in this case,
Either the line width is converted using a coordinate system obtained by converting a circle into an ellipse to make the line width uneven, or the broken line pattern is used without being subjected to coordinate conversion.

[0008] As the simplest example, when a line segment is drawn on a plane, two kinds of distance-related attributes of width and length are required for drawing. The coordinate system that defines the meaning of the attribute value related to the distance need not be the same as the coordinate system that defines the drawing shape. However, the above PostSc
In a conventional apparatus such as a processing system of a rip language, it is implicitly assumed that the same coordinate system is used for these attribute values, so that the figures that can be drawn are limited.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and clarifies the meaning of an attribute value across a hierarchy in graphic information having a hierarchical structure. It is an object of the present invention to provide a document information processing apparatus and a document information processing method capable of drawing a figure or converting a figure by a combination of the above.

[0010]

The document information input in the present invention is composed of content information representing the contents of the components of the document, attribute information representing the rendering attribute, coordinate system information representing the coordinate conversion, and the components of the document. Structure information representing the set and the content information,
The attribute information is information that is a combination of part or all of hierarchical information indicating a hierarchical relationship between the structure information and the structure information. According to the present invention, such document information is received by the document information input means and passed to the document information management means. The document information management means registers and manages the received document information using a hierarchical structure. When registering the document information in the hierarchical structure, the attribute information in the document information is checked, and for the attribute related to the distance, coordinate system information giving its meaning is specified. The attribute information registered using the hierarchical structure is interpreted by the drawing information generating means. The drawing information generating means associates the content information and the attribute information appearing in the hierarchical structure, and generates drawing information specifying an independent coordinate system for each. Thus, for example, in the case of the above-described drawing of an ellipse, it is possible to define a line width and a broken line pattern in different coordinate systems. Becomes possible.
In addition, for example, when the same line width is set for a figure or a component of a document in which a different coordinate system is defined,
It is possible to draw using the attribute values related to the distance defined in the independent coordinate system, regardless of the coordinate system of the graphic or the component of the document to be converted.

[0011]

FIG. 1 is a block diagram showing an embodiment of a document information processing apparatus according to the present invention. In the figure, 1 is a document information input unit, 2 is a document information management unit, and 3 is a drawing information generation unit. The document information input means 1 interprets and inputs document information. The document information management means 2 registers and holds the output of the document information input means 1 in a hierarchical structure. The drawing information generating means 3 interprets the hierarchical structure held in the document information managing means 2 and generates drawing information necessary for drawing.

The document information provided to the document information input means 1 has a structure representing a set of contents information representing the contents of the components of the document, attribute information representing the drawing attribute, coordinate system information representing the coordinate transformation, and the components of the document. The document information input means 1 is provided with a combination of some or all of them. That is, as the document information, a set of the content information, the content information and the attribute information corresponding thereto, a plurality of sets of the content information and the attribute information, the structure information for integrating them, the structure information and the attribute information corresponding thereto are given. In some cases, coordinate system information indicating coordinate conversion is added.

The input document information is passed to the document information management means 2 and registered in a hierarchical structure. The data structure that realizes this hierarchical structure is a tree structure, in which the leaves of the tree structure correspond to the components of a single document, and the nodes that combine the branches from them correspond to the structure information. A node can have attribute information and coordinate system information, and the coordinate transformation and attribute information represented by the coordinate system information are effective for nodes and leaves below the node where these appear. I do. That is, the document information management means 2 forms a partial tree from the document information input by the document information input means 1 and further forms the tree structure by adding the configured partial trees to express hierarchical document information. . The structure of the subtree and the relationship between the subtrees may be given as hierarchical information included in the document information, or the document information input means 1 or the document information management means 2 may judge from the given document information. When the subtree is obtained, the document information management means 2 examines the content of the subtree, associates the attribute value related to the distance appearing in the attribute information with coordinate system information indicating the coordinate system giving the meaning, and adds it.

The drawing information generating means 3 scans the tree structure held by the document information managing means 2 and generates drawing information necessary for drawing. Although the required format of the drawing information is various, the present invention does not limit the format of the drawing information. When the tree structure is scanned to generate the drawing information, if the attribute information necessary for the document information appearing on the leaves of the tree structure is insufficient, the tree structure is traced up to obtain the necessary attribute information. Further, the coordinate conversion is determined by obtaining the product of the coordinate system information. In this way, necessary information is obtained from the tree structure, and drawing information is generated using the information. If it is permitted to describe the reference relation in the drawing information, a subtree or the entire tree structure including necessary information may be used as the drawing information.

FIG. 2 is a block diagram showing an example of a page description language interpretation system to which an embodiment of the document information processing apparatus according to the present invention is applied. In the figure, 11 is an input analysis unit, 12 is an internal data management unit, 13 is a drawing data generation unit, and 14 is a drawing engine. The page description language interpretation system is provided with document information described in a page description language, interprets the provided document information, generates drawing information, and outputs the drawing information to, for example, the drawing engine 14 for drawing. The input analysis unit 11 in the page description language interpretation system shown in FIG. 2 corresponds to the document information input unit 1 of the document information processing apparatus shown in FIG. 1, and the internal data management unit 12 corresponds to the document information management unit 2. , The drawing data generator 13 corresponds to the drawing information generator 3.

The input analysis unit 11 converts a given page description language into an internal data structure,
Pass to. The internal data management unit 12 registers the page description language (hereinafter referred to as internal data) converted into the internal data structure passed from the input analysis unit 11 in a tree structure. For example, when all data constituting one page is registered, the drawing data generating unit 13 scans the tree structure registered in the internal data managing unit 12, generates data necessary for drawing, and generates the drawing engine 14 as drawing information. Pass to. Drawing engine 14
Performs drawing processing according to the passed drawing information.

FIG. 3 is a flowchart showing an example of processing in the internal data management unit. Internal data management unit 1
In S2, it is determined whether or not the internal data passed from the input analysis unit 11 has been completed in S21, and the registration processing of the internal data is completed when the internal data has been completed. When the internal data is passed from the input analysis unit 11, it is determined whether the internal data passed in S22 is a command representing coordinate transformation.
If the instruction indicates a coordinate transformation, in S23, a new branch is generated in the tree structure, and the branch is moved to the previous node of the branch. In S24, the internal data is registered at the node currently being processed. At this time, the contents of the internal data are checked, and when the internal data representing the attribute value related to the distance is registered, information indicating the coordinate system giving the meaning is added. In S25, it is determined whether or not the internal data is a drawing command. If the command is a drawing command, the process moves to a node on the branch of the node currently being processed in S26.

By such processing, the internal data representing the coordinate transformation represents the start of the subtree, the drawing command represents the end of the subtree, and the start and end of the structure can be expressed implicitly. . In the present invention, the format of the structure managed by the internal data management unit 12 is not limited to this. For example, if there are symbols and grammars corresponding to the start and end of the structure in the page description language, the input analysis unit 11 detects them and generates internal data representing the structure and passes it to the internal data management unit 12. Good.

The drawing data generator 13 generates drawing information by adding a drawing attribute to information representing the shape of a figure to be drawn. At this time, if all the necessary drawing attributes are not provided for the leaves of the tree structure, the necessary drawing attributes are acquired by sequentially following the above nodes.

Next, the operation when a specific input is given will be described. FIG. 4 is an explanatory diagram of an example of a page description language given in a first specific operation example of a page description language interpretation system to which an embodiment of the document information processing apparatus according to the present invention is applied. Similarly, FIG. 6 is an explanatory diagram of an example of the registered tree structure, and FIG. 7 is an explanatory diagram of an example of a similarly drawn figure.

The page description language shown in FIG. 4 expresses an ellipse by performing coordinate transformation on a circle. Line a designates a line width at the time of drawing. Here, 5 is specified as the line width. Line b represents coordinate transformation in the x-axis and y-axis directions. The first parameter represents the magnification on the x-axis, and the second parameter represents the magnification on the y-axis.
In this example, coordinate conversion is shown in which the unit length in the x-axis direction is doubled. Line c is a drawing command for drawing a circle or an arc. The first and second parameters indicate the coordinates of the center, the third parameter indicates the radius, and the fourth and fifth parameters indicate the angle at which the arc is drawn. In this example, the center coordinates are (0,
0), the radius is 100, the fourth, and the fifth from the third parameter.
Is specified to draw an arc from 0 ° to 360 °, that is, a circle. At this time, since it is specified that the line b is to be doubled in the x-axis direction, a circle that is doubled in the x-axis direction, that is, an ellipse is drawn.

When a command described in a page description language as shown in FIG. 4 is given, the input analysis unit 11 sequentially converts the command into an internal data structure to obtain internal data as shown in FIG. Line d specifies the line width,
This is the same as line a in FIG. Line e indicates coordinate transformation. coord; [p, q, r, s,
t, u], the parameters p to u are defined as

(Equation 1) Represents the elements p to u of the transformation matrix in. In this example, since p = 2.0 and s = 1.0, 2 in the x-axis direction
It represents a coordinate transformation that doubles. The line f is a drawing command of a circle or an arc, and the parameters are the same as those of the line c in FIG. The internal data converted by the input analysis unit 11 is passed to the internal data management unit 12.

Upon receiving the internal data shown in FIG. 5, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. First, the line d shown in FIG.
When no internal data is received, a new node is created because no node has been created, and the internal data is registered at the node in S24 of FIG. That is, in FIG. 6, a new node is created below the black circle indicating the route, and the contents of the line d are registered, as shown in FIG. 6A.

When registering the internal data in the tree structure,
Each coordinate transformation is given a unique label,
For the attribute value related to the distance, a label of the coordinate conversion effective for the node is added. Since no coordinate transformation has been defined for the line d, a label indicating the default coordinate system is added as a coordinate transformation label. Here, the label “c0” is added as an example. In this default coordinate system, the unit lengths of the two coordinate axes are assumed to be equal. In FIG. 6, a coordinate transformation in which the unit length of two coordinate axes is equal to the route is tentatively indicated by a broken line.

Next, when the line e shown in FIG. 5 is received, a new branch is created from the node in which the line d is registered in S23 of FIG. Register the contents of line e.
The coordinate transformation is given a new label. Here, the label “c1” is given. This results in a tree structure as shown in FIG.

Subsequently, when line e is received, S2 in FIG.
In 4, the content of the line e is registered at the same node as the line d. Since line e is a drawing command, S26
Moves the processing to the node at which the line d above is registered. By registering the line e, a tree structure as shown in FIG. 6C is created.

In this example, an elliptical shape is given by defining a circular shape in a coordinate system in which two coordinate axes have different unit lengths. Hereinafter, such a coordinate system will be referred to as a variable magnification coordinate system. The line width is given in a coordinate system in which the unit lengths of the two coordinate axes are equal. Hereinafter, such a coordinate system is referred to as an equal-size coordinate system. These names are used for explanation in this example, and the circle is the same-size coordinate system and the line width is the variable-size coordinate system, or the coordinate system that gives the line width and the shape of the ellipse or the circle is the same variable-size coordinate system. The coordinate system or the same-size coordinate system may be used, or different scaled coordinate systems may be used.

The drawing data generation unit 13 sequentially follows the tree structure registered in the internal data management unit 12 and generates drawing data in a format that the drawing engine 14 can receive. In this example, since the shape of the drawing figure is an ellipse and the line width is given in the same-size coordinate system, the figure to be drawn is an ellipse having a constant line width as shown in FIG.

FIG. 8 shows a second embodiment of the page description language interpretation system to which the embodiment of the document information processing apparatus according to the present invention is applied.
FIG. 4 is an explanatory diagram of a specific operation example of FIG. In the second specific example, a case where an instruction in a page description language as shown in FIG. 8A is given will be described. In this example, the coordinates are given first, followed by the line width designation, and finally the drawing command.

As in the first operation example described above, FIG.
8 is converted into internal data as shown in FIG. 8B by the input analysis unit 11 and passed to the internal data management unit 12. Upon receiving the internal data shown in FIG. 8B, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. In this example, a node is created by the first coordinate transformation, the content is registered, and a label “c1” is given. The contents of the two lines following the created node are also registered, and a tree structure as shown in FIG. 8C is formed.

In this example, both the drawing command and the line width are given in a variable-magnification coordinate system. Therefore, the drawn figure has a shape in which a circle having a constant line width is extended in the horizontal direction, as shown in FIG. That is, the overall shape is an ellipse, and the line width is the line width given at the upper and lower parts of the ellipse, and is wider than the line width given at the left and right parts of the ellipse.

FIG. 9 shows a third embodiment of the page description language interpretation system to which the embodiment of the document information processing apparatus according to the present invention is applied.
FIG. 4 is an explanatory diagram of a specific operation example of FIG. In the third specific example, a case where an instruction in a page description language as shown in FIG. 9A is given will be described. In this example, a dashed line pattern is given along with the line width before the coordinate conversion. The dash instruction on the second line in FIG. 9A indicates a dashed line pattern, the first parameter indicates a drawing length, and the second parameter indicates a length of a non-drawing portion following the drawing portion. I have.

As in the first operation example described above, FIG.
9 is converted into internal data as shown in FIG. 9B by the input analysis unit 11 and passed to the internal data management unit 12. Upon receiving the internal data shown in FIG. 9B, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. In this example, a node is created and registered by specifying a line width, and a subsequent specification of a broken line pattern is also registered at this node. Next, since the coordinate transformation is passed, a node is created at a lower level, the content is registered, and a label “c1” is given. A drawing command is also registered at this node. Thus, a tree structure as shown in FIG. 9C is formed.

In this example, the line width and the dashed line pattern are given in the same-size coordinates, and the drawing command is given in the variable-size coordinate system. Therefore, as shown in FIG. 9D, the drawn figure is an ellipse having a constant line width and a constant interval between broken lines.

FIG. 10 is an explanatory diagram of a fourth specific operation example of the page description language interpretation system to which the embodiment of the document information processing apparatus of the present invention is applied. In the fourth specific example, a case where an instruction in a page description language as shown in FIG. In this example,
The instruction is given in the order of a broken line pattern instruction, coordinate conversion, line width instruction, and drawing instruction.

As in the first operation example described above, FIG.
The description in the page description language as shown in FIG. 10A is converted into internal data as shown in FIG. 10B by the input analysis unit 11 and passed to the internal data management unit 12. Upon receiving the internal data shown in FIG. 10B, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. In this example, a node is created and registered by designating a broken line pattern. By the subsequent coordinate conversion, a branch is created below the node where the dashed line pattern is registered, the coordinate conversion is registered at the node at the tip thereof, and the label “c” is registered.
1 "is given. The next line width designation and drawing command are also registered at the same node as the coordinate transformation. Thus, FIG.
A tree structure as shown in FIG.

In this example, the dashed line pattern is given by the same-size coordinates, and the line width and the drawing command are given by the variable-size coordinate system. Therefore, as shown in FIG. 10D, the figure to be drawn has an elliptical shape obtained by extending a circle having a constant line width in the horizontal direction, and the ellipse is provided with a broken line pattern at a constant interval.

FIG. 11 is an explanatory diagram of a fifth specific operation example of the page description language interpretation system to which the embodiment of the document information processing apparatus according to the present invention is applied. In the fifth specific example, a case where an instruction in a page description language as shown in FIG. In this example,
The line width instruction, coordinate conversion, broken line pattern instruction, and drawing instruction are given in this order.

As in the first operation example described above, FIG.
The description in the page description language as shown in (A) is converted by the input analysis unit 11 into internal data as shown in FIG. 11 (B) and passed to the internal data management unit 12. Upon receiving the internal data shown in FIG. 11B, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. In this example, a node is created and registered by designating the line width. By the subsequent coordinate conversion, a branch is created below the node whose line width is registered, the coordinate conversion is registered at the node at the tip, and a label “c1” is given. The specification of the next broken line pattern and the drawing command are also registered at the same node as the coordinate conversion. Thus, FIG.
A tree structure as shown in (C) is formed.

In this example, the line width is given by the same size coordinates,
The dashed line pattern and the drawing command are given in the variable magnification coordinate system. Therefore, as shown in FIG. 11D, the drawn figure has a constant line width, and its shape is an elliptical shape obtained by extending a circle on which a dashed line pattern is formed at regular intervals and extending in the horizontal direction. Since the dashed line pattern extends in the horizontal direction after being provided at a constant interval in the circle, the interval is substantially set at the left and right of the ellipse, but the interval is extended at the upper and lower portions.

FIG. 12 is an explanatory diagram of a sixth specific operation example of the page description language interpretation system to which the embodiment of the document information processing apparatus of the present invention is applied. In the sixth specific example, a case where an instruction in a page description language as shown in FIG. In this example,
The coordinate conversion, the line width instruction, the broken line pattern instruction, and the drawing command are given in this order. The same is true even if the order before and after the line width instruction and the broken line pattern instruction is reversed.

As in the first operation example described above, FIG.
The description in the page description language as shown in FIG. 11A is converted into internal data as shown in FIG. 12B by the input analysis unit 11 and passed to the internal data management unit 12. Upon receiving the internal data shown in FIG. 12B, the internal data management unit 12 sequentially registers the internal data as a tree structure according to the flowchart shown in FIG. In this example, a node is created by the first coordinate transformation, the content is registered, and a label “c1” is given. The following three lines, that is, a line width instruction, a broken line pattern instruction, and a drawing instruction are registered at the same node as the coordinate conversion. Thus, a tree structure as shown in FIG. 12C is formed.

In this example, the line width, the dashed line pattern, and the drawing command are given in a variable coordinate system. As a result, as shown in FIG. 12D, the drawn figure is an ellipse obtained by extending a circle in which a dashed line pattern is formed at a constant line width and at a constant interval in a horizontal direction. The dashed line pattern has a substantially set interval on the left and right sides of the ellipse, but the interval extends on the upper and lower portions. The line width is also substantially equal to the width set above and below the ellipse, but the line width becomes thicker at the left and right portions.

Of the above specific examples, the fourth and fifth specific examples in which the line width and the broken line pattern are given in different coordinate systems cannot be expressed by, for example, PostScript. This is because PostScript associates the attribute value with the coordinate system all at once when the drawing command is issued.

As described above, by using the present invention, it is possible to clarify the meaning of the attribute value related to the distance, and it is possible to express a graphic that cannot be expressed by the conventional page description language.

In the figure, 51 is a text part, 52 is a pie chart part, 53
Is the bar graph part. The document shown in FIG. 15 is a specific document displayed on the display 42 in FIG. The characters are shown by broken lines. The text part 51 is composed of text created by an editor or the like. Pie graph part 52 and bar graph part 53
Is a graphic representing a graph created by a different application such as statistical software. Thus, a desired document can be created by arranging various documents and data created by various applications according to the layout. At this time, for example, the size of a figure or an image created by each application or the like does not always match a desired document, and may be enlarged or reduced or deformed as appropriate. In addition, components to be arranged, such as documents and charts, may be composed of a plurality of components, and the editing process for the higher-level components can be applied to all the lower-level components. Of course, the configuration may be such that editing processing can be performed on lower-level components.

Therefore, a tree structure as shown in FIG. 16 is formed.

Here, it is assumed that the pie chart portion 52 and the bar graph portion 53 have different appearances because they are created by different applications. In the example shown in FIG. 15, the line for drawing the pie chart in the pie chart portion 52 is thick, and the line for drawing the bar graph in the bar graph portion 53 is thin. In order to unify such non-uniform line widths, consider a process of making the line widths of lines appearing in two graphs the same. At this time, since the graphic information representing the graphs of the pie chart portion 52 and the bar graph portion 53 are given coordinate transformation for designating the position and size, the line width values appearing in these attribute values are set to the common values. Does not give the same line width.

Therefore, in an interactive document editing system to which an embodiment of the document information processing apparatus of the present invention is applied, attribute values common to these figures are specified as follows. First, a group of a pie chart portion 52 and a bar graph portion 53 for setting a common attribute value is designated using the editing operation input unit 33. FIG. 17 is an explanatory diagram showing a specific example of group designation. The arrow in the figure is a mouse cursor. For example, as shown by a dotted line in FIG. 17, a group is designated by designating a range including a target component using a mouse 44. In the example shown in FIG. 17, it is specified that the pie chart and the bar graph are enclosed, and the pie chart portion 52 and the bar graph portion 53 are grouped. Of course, each component may be specified by another method such as pointing and clicking with a mouse.

FIGS. 18 and 19 are explanatory diagrams of an example of a tree structure edited in an example of an interactive document editing system to which an embodiment of the document information processing apparatus of the present invention is applied. The editing operation for designating the components to be grouped as described above is transmitted to the internal data management unit 32. The internal data management unit 32 receives the designation of such a group,
Add a new node with branches to the members of the group. As a result, the tree structure shown in FIG. 16 is changed to the tree structure shown in FIG.

Next, the line width is designated as one of the attributes for this group by using the editing operation input section 33. The information on the designated line width is registered in the newly added node, as shown in FIG. The registered line width information is applied to branches below the node where the line width information is registered. At this time, a label of the coordinate system corresponding to the entire page is given to the attribute of the line width added as a coordinate system giving meaning. As a result, the meaning of the line width is not interpreted in another coordinate system even in the branch below the node. Of course, a unique coordinate system for the line width can be given.

When the document editing is completed in this way, the document data output unit 35 scans the tree structure held in the internal data management unit 32 and creates document data in a format designated according to the purpose such as printing or transmission. Output. FIG.
FIG. 9 is an explanatory diagram illustrating a specific example of an output document. By performing the processing for keeping the line width constant for the pie chart portion 52 and the bar graph portion 53 as described above, the appearance of the pie chart and the bar graph can be made the same.

By using the method described above, the meaning of the attribute value relating to the distance can be clarified, and the attribute value of the document information having a hierarchical structure can be operated accurately.

[0058]

As is apparent from the above description, according to the present invention, in graphic information having a hierarchical structure, the meaning of attribute values across strata is clarified, and coordinate conversion for graphic shapes and attribute values for distances are performed. This makes it possible to process the coordinate transformation independently of each other, which has the effect of enabling rendering with a combination of attribute values that has conventionally been difficult to specify.
