Abstract

PROBLEM TO BE SOLVED: To easily attain re-use such as correction while holding a work intention, and to attain work prediction by using candidates for reuse by extracting the dependency of graphics edited in the past, extrapolating a present working process with the dependency as a pattern, and plotting and displaying a work completion predicted graphic. SOLUTION: In a method for inputting a coordinate value and a plotting command parameter (S1), and plotting and displaying a graphic or a character, a plotting work is recorded as reproducible information (S2), and the dependence of graphics edited in the past is extracted based on a recorded work history (S3). A present working process is extrapolated by using the extracted dependence as a pattern (S4), the following works are predicted and executed (S5), and a work completion predicted graphic is plotted and displayed (S6). Thus, at the time of repeating fine and large-scaled plotting works having the same intention in various phases, the load of a user is sharply reduced by the reuse of the past works.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic display method and apparatus and a storage medium storing a graphic display program, and in particular, to repeat a complicated but consistent intentional graphic editing operation according to various situations. In such a case, the editing operation is performed only once by an operation that clearly understands the intention, and the editing is performed accurately reflecting the user's work intention, and the work is reused in another situation and The present invention relates to a graphic display method and apparatus having a function of reducing a user's work load by predicting and acting on behalf of an editing work in response thereto, and a storage medium storing a graphic display program.

2. Description of the Related Art As a method used in a conventional graphic display device, there is a method using a GUI. In general, GUIs have been considered intuitive and easy to understand, but are not suitable for operations that directly handle logical information. By estimating and interpolating the intention, it is becoming possible to realize a high-level interaction while maintaining the clarity.

[0003] Methods using domain-specific constraints and functional inference, and programming based on examples (A. Cyphered Watch W
hat I Do: Programming by Demonstraiton.MIT Press,
(1993)) is representative of such an approach. For example, a drawing device (DL Maulsby, I.
H. Witten, KA Kittlitz. Metamouse: Specifying gr
aphical procedures by example. Computer Graphics 2
3,3, pp.127-136 (1989)) is based on geometric constraints,
You can learn the procedure from the examples.

[0004]

However, in a conventional graphic display device, when a user edits a graphic, an instruction for directly inputting geometrical information to the device explicitly is "alignment" or the like. Since the user is very limited, the user is required to make fine adjustments while looking at the editing screen, which is a burden on drawing.

[0005] Further, since the geometrical intention of the work cannot be explicitly input to the device, when the work result is corrected or reused, the change of the correction value or the change of the work situation is not changed. There is no other way than to infer from the implicit geometric information what effect it will have on the work result. Such an estimation is computationally expensive and inaccurate, and cannot be used for reusing a large-scale drawing operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and in a graphic editing operation, it is possible to explicitly specify geometric information and the like, enable a strict editing operation, and include a geometric relationship. Stores a graphic display method and apparatus and a graphic display program that can be easily reused such as modification and diversion while preserving a wide and strict work intention, and that can predict work using possible reuse candidates. It is an object of the present invention to provide a storage medium that has been used.

[0018]

FIG. 3 shows a conceptual configuration of a graphic display device according to the present invention. The figure display device shown in FIG. 1 includes an input unit 10, an operation history recording unit 20, a dependency extraction unit 30, a work prediction / execution unit 40, and a figure editing / display unit 50. The input unit 10 inputs a user's editing intention.

The operation history recording unit 20 records a user's editing intention and an editing target as a history element. The dependency extracting unit 30 extracts the dependency of the past edited graphic from the accumulated work history information. The work prediction / execution unit 40
Based on the dependency, the editing operation is configured and executed in the light of the current editing status, and the editing operation is predicted.

The graphic edit / display unit 50 interprets the edit command and actually edits and displays the edit command. Each of the above-described components is realized by, for example, a computer. Next, an example in which the graphic display device having the above configuration is applied to a drawing editing device having a prediction function will be described. First, the user inputs an editing instruction from the input unit 10 using a pointing device or the like. Since editing and drawing can be regarded as graphic rewriting work, this work involves specifying a page on which rewritable rules (plural) are described, and then specifying a rewriting portion f and a parameter e with a pointing device or the like. Can be done by Such a rewrite rule can be arbitrarily added by the user using the already defined drawing function itself. The specific rewriting rule γ applied at the time of rewriting is automatically selected according to a portion to be rewritten from the designated page (usually, the longest match of the rewritten portion). Each rewrite rule is described by a figure before and after rewrite including an event, and the figure before rewrite of the rule matches the figure in the work area, without regard to parameters such as position, length, orientation, etc., and matches the parameters of the work area. Tell the figure after rewriting the rules.

The graphic editing / display unit 50 deletes a matched part of the work area and draws a rewritten graphic having new parameters. When the user issues an event using the pointing device, the user selects one of these command groups and specifies a valid command. The rewriting portion and the parameter are designated by the user as a drag event occurrence point (point) and a drag length, respectively. In particular, when used as a location where both end points of a drag event occur, the information on the drag length is not necessary because it is included in this information. The work performed in each step in this manner can be completely specified by the event e and the page p specified when the event was issued. Hereinafter, these sets w = (e, p) are referred to as “work designations”.

The work designation w is interpreted and displayed by the graphic editing / display unit 50 and, at the same time, is recorded as editing operation history information by the operation history recording unit 20. The editing operation history information holds such a past drawing command. Such instructions include an instruction to activate the edit prediction function. Next, the dependency extraction unit 30 monitors the editing operation history information, and when detecting that a prediction start command is added thereto, activates a prediction operation. The prediction operation is also generated by a dependency extraction process executed in the dependency extraction unit 30 and a work prediction execution process. In the dependency extraction process performed by the dependency extraction unit 30, by analyzing the recorded editing operation history information, each input / output relationship of a series of graphic rewriting commands (rewriting rules) issued by the user is used as a clue. Only commands relevant to each drawing operation can be extracted in the order in which they were issued.

In the predictive execution process performed by the work predicting / executing unit 40, a dependency similar to the dependency between the figures created by the current drawing work is determined by the dependency extracting unit 30.
, And extrapolates the current one with the found dependencies to predict the drawing operation. Specifically, in the work history that partially produced the same dependency, the command sequence of the part corresponding to the extrapolated part was re-issued in the context of the current dependency while preserving the work intention of the past, Operations can be automated according to the current situation.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. Next, the above operation will be specifically described using an application example. [First Embodiment] FIG. 4 shows a configuration of a graphic editing / display apparatus according to a first embodiment of the present invention.

The figure editing / display device shown in FIG. 1 comprises a work history table 21, a control unit 51, a drawing job storage file 55, a coordinate value storage table 21, and a display unit 56. The configuration shown in FIG. 3 specifically shows the configuration shown in FIG. The operation history recording unit 20 includes a work history table 21 and a coordinate value storage table 22 as specific configurations.
The work history table 21 includes a pointer for storing drawing commands in the drawing execution order, and a coordinate value storage table 22 for storing coordinate values required for the drawing commands.
The pointer to is recorded. Coordinate value storage table 22
Is used to extract the relationship between the work history information and the currently input coordinate values in the dependency extraction unit 30 shown in FIG.

The control section 51 performs an editing control operation in the figure editing / display section 50 in FIG. At this time, the control unit 51 stores the work history table 21 and the coordinate value table 35
And controls the display unit 56 to display the edited graphic or the corrected graphic based on the contents of the drawing job storage file 55. Drawing job storage file 55
Are included in the figure editing / display unit 50, and store drawing commands for drawing on the display unit 56 and rewrite commands for each page. The display unit 56 has a display function based on a command from the drawing job storage file 55 in the graphic editing / display unit 50 in FIG.

Hereinafter, a specific example will be described. For example, it is assumed that the desired graphic is the one shown in FIG. Here, it is assumed that the hypotenuse of the triangle is equal to the height of the rectangle (hereinafter, it is assumed that a similar figure having such a geometric relationship is repeatedly drawn). FIG. 6 shows an example of a rewrite command group necessary for drawing a desired graphic according to the embodiment of the present invention. When using the rewrite command group, the apparatus user can draw in accordance with the procedure shown in FIG. Note that the issuance event is omitted. The meaning of the rewrite command group shown here is as follows in the order of page numbers.

1. A perpendicular line of the length of the vertical component of the drag by the pointing device is added, and the end point of the vertical line segment is rewritten into a rectangle including the vertical line segment as a side and the bottom side as the horizontal component length of the drag. 2. Add a circle centered on the starting point of the drag and having a radius equal to the drag length. 3. One mark is added on the intersection of the two circles centered on the starting point and the ending point of the drag.

4. Add a line segment with the start and end points of the drag as both end points. 5. Click to delete a circle or mark. The numbers in FIG. 7 represent drawing steps (pages used). In this example, the rewritten portion is determined as "a figure having an event generation location (point) at an end point or a center".

The procedure of FIG. 7 will be described step by step. Step 101) First, a vertical line segment is generated on the command page “page 1”. Drag from a point other than the upper end point of the vertical line segment generates a vertical line segment having the point as an end point and the vertical component of the drag as a length. At this time, both end points of the line segment are free points. Step 102) Next, a rectangle is generated using the same command page 1. The drag at the upper end point of the vertical line segment is a rectangle whose height is the line segment length and whose base is the drag horizontal line segment length, with the upper left corner as the line segment upper end position. The rectangle is assumed to be composed of four line segments. At this time, the upper right point of the rectangle is a free point, while the lower right point is a dependent point.

Step 103) Command page “page”
2 "creates a circle. The center is the drag start point and the radius is the drag length. This command does not create a new feature point. Step 104) Same as Step 103. Step 105) Command page" page 3 " Creates a point at the intersection of two circles. In this case, the drag is from the center of the event circle to the center of another circle, and the generated point is defined as the right side in the drag traveling direction. The generated point is a dependency point.

Step 106) Command page “page”
4 ”generates a line segment. At this time, a line segment is generated depending on the point generated in step 105. Step 107) Same as step 106. Step 108) A circle is formed on the command page“ page 5 ”. Erase, so that the click circle above the center point of the circle disappears.

Step 109) Same as step 108. (Step 110) The point is erased in the same command page “page 5” as in Step 108. Clicking on a point will make it disappear. Finished. Thus, the drawing operation is completed. As can be seen from the work process, the analog elements included in the user's operation are only the upper left position and the vertical and horizontal sizes of the rectangle, and all other editing can be performed only by rules.

Work history table 2 recording the above procedure
1 is as shown in FIG. In the figure, fn of "start" and "end" indicates a free point, and bn indicates a dependency point. However, in the figure, the number in the “step” column is the number of the upper step, the symbols in the other columns are the coordinate data of the point generated during drawing and a pointer to the rewrite command, and the same symbol shares the same data. It is assumed that FIG. 9 shows the correspondence between these points and the points of the drawing figure.

For example, consider a situation in which FIG. 5 is drawn in the procedure shown in FIG. 7, and then a figure with a similar (geometric) intention but with a slightly different shape is to be drawn. The user draws a rectangle with new desired parameters (side position, length, etc.) again using the command group of FIG. Then, issue the prediction command,
The apparatus searches the work history table 21 for a history of drawing a rectangle while ignoring the parameters, and applies the current new parameters to the obtained work history (difference command).
Is re-issued, the triangle is automatically drawn such that the hypotenuse is the height of the current rectangle and the bottom is the top of the rectangle.

Note that "page.No." p.1 to p.5 shown in FIG.
Are combined, and step 101
When the drawing is performed in accordance with the procedures from Step 110 to Step 110, all of the obtained drawings shown in FIG. 5 satisfy the condition that "the height of the rectangle is the same as the length of the hypotenuse of the triangle." In the present invention, once a figure that satisfies the above conditions is drawn in the edit mode, the coordinate values of the vertices and the like of the figure previously input when the figure is drawn based on the work history and the like stored in the edit mode in the prediction execution mode. Is changed, and a figure satisfying the same condition is redrawn.

The operation in the edit mode described above is as follows.
It looks like this: In drawing, a drawing command is specified for each step, and a start point and an end point for a straight line and an arbitrary point on the center and the circumference for a circle are designated by a pointing device of the coordinate value input unit 1. While drawing. At this time, in order to redraw a figure satisfying the condition in the prediction mode, the control unit 51 sets (1) pointers to drawing commands (page.No.) start points, end points, and gererated points for each step. An operation history table 21 (FIG. 8) composed of a pointer to the coordinate value storage table 22 to be stored is created. (2) For each step, the control unit 51 stores the coordinate value specified by the pointing device in the coordinate value storage table 22.
If there is no match in the coordinate value storage table 22, a new coordinate value is added and a pointer to the coordinate value is written in the work history table 21. If there is a match, a pointer to the coordinate value is written in the work history table 21. In addition, the coordinate data of the point generated during the drawing is written in a corresponding part of the coordinate value storage table 22 and a pointer to the coordinate value is written in the work history table 21.

The operation in the prediction mode will be described. (1) In FIG. 4, the point at which the coordinate value can be changed is represented by f input by the pointing device of the coordinate value input unit 10.
1, f2, f3 (defined as free points), and the user instructs which coordinate value is to be changed using a pointing device. (2) The control unit 51 compares the coordinate value input in (1) above with the coordinate value of each free point in the coordinate value storage table 22, and identifies a point to be changed.

(3) The corrected coordinate value is inputted by the pointing device of the coordinate value input section 10. (4) The control unit 51 corrects the coordinate value corresponding to the change target point in the coordinate value storage table 22. (5) Display unit 56 based on work history table 21
Performs redrawing. At this time, the work history table 21
In, the corrected coordinate values are “start points, end
Only if it is one of "points", redraw of the step is performed.

Next, an example in the case where there is a coordinate correction instruction from the coordinate input unit 10 will be described. FIG. 10 shows the first embodiment of the present invention.
FIG. 11 is an example of a work history table having corrected coordinate values according to the embodiment of the present invention. FIG. 11 is an example of a case where a change is made to a figure drawn in the edit mode according to the first embodiment of the present invention. There is an example that has been changed to (x _3, y ₃₎ from _{(x '3, y' 3} ).

In this case, the coordinates of the point f3 are corrected, and
This is an example in which (x ₃ , y ₃ ) → (x ′ ₃ , y ′ ₃ ).
Since step 101 does not include the corrected coordinates f3, it is not redrawn. In step 102, “end
The points "" include the modified coordinates, so redraw.
Hereinafter, drawing is executed in steps 104, 105,
Steps 103, 106, 108 and 110 do not execute drawing.

As described above, the work history table 21 and the coordinate value table 54 relating to the drawing are provided and
By linking with the pointer as shown by 0, the drawing conditions indicated by the figure are described in the work history table 21, the actual input coordinates are described in the coordinate value table 54, and the coordinate values are changed only in the coordinate value table 54. Therefore, a figure satisfying the geometric condition can be appropriately drawn.

[Second Embodiment] A once drawn figure can be updated as a whole by re-executing necessary work in accordance with the change of the initial value, so that it can be used as a spreadsheet of figure numbers. For example, the fields of the spreadsheet are [x, y, z, total = x + y + z]. Now, as data,

[0044]

(Equation 1)

It is assumed that the data is given as a histogram as shown in FIG. First,

[0046]

(Equation 2)

Let us calculate The first step of addition is
To join two bars together at a horizontal line.
Once this is done, you can use the compass twice,
As shown in (B), a bar of the sum length can be set up on the horizontal line. By repeating this operation, FIG.
As shown in (C)

[0048]

(Equation 3)

Is obtained. When the answer is obtained, the user has strictly defined the field total. That is, put the window in reuse mode and set the length of the x field to

[0050]

(Equation 4)

By changing the value to the above, the prediction system is started, the procedure described above is re-executed, and the value of total (the height of the bar) is immediately updated (the irrational number emphasizes the strictness. To do that). As arithmetic, besides sum,
If the length of the unit is defined, operations required for a normal spreadsheet, such as a quotient (reciprocal), a product, an n-segment, and a square root, can be easily defined from a drawing.

The details of the addition method used above will be described with reference to FIG. Step 201) A vertical line is extended from the lower point A of the bar x in a direction opposite to the bar. Step 202) The radius of the bar x is the height of the bar around the lower point A.

[0053]

(Equation 5)

Draw a circle. Step 203) A point C is generated at the intersection (below) of the line drawn in step 201 and the circle drawn in step 202. Step 204) A line segment centering on the point C and connecting the upper point D of the bar y next to the bar x.

[0055]

(Equation 6)

Draw a circle whose length is the radius. Step 205) Generate a point E at the intersection of the circle drawn in step 204 and the horizontal reference line. Step 206) With the point E as the center, the radius is

[0057]

(Equation 7)

Draw a circle so that Step 207) A sufficiently long vertical line segment is drawn above the horizontal reference line with the point E as an end point. Step 208) A point F is generated at the intersection (above) of the line drawn in step 207 and the circle drawn in step 206. length

[0059]

(Equation 8)

Is the sum of the height of the bar x and the height of the bar y. [Third Embodiment] In addition, by modifying parameters on rules written on a page and redrawing them without changing the parameters at the time of work, more sophisticated and flexible reuse is possible. For example, in FIG. 14, the recursive graphic is drawn by including an event in the graphic after the rewriting of the rule (displayed in the upper right rectangular area), but by changing the parameter: length of the graphic after the rewriting. 15 can be corrected.

In FIGS. 14 and 15, two commands are combined to form one command.
As shown on the right side of FIGS. 14 and 15, after drawing for the length of a, the light is branched into two line segments b1 and b2 at angles θ1 and θ2. In other words, the content of the combination of the two commands is “based on the branched line segment,
2) and branch at a line segment ratio (b1 / a, b2 / a),
When the radius becomes smaller than the radius of the circle shown on the left side of FIGS. 14 and 15, the branching stops. "

In FIG. 14, θ1 = θ2, b1 = b
2. FIG. 16 shows an example of each table of the work history table 21, the coordinate value storage table 22, and the drawing job storage file 55 in this case. In the present invention, the contents described in the above embodiment are configured as a program, and the work history table 21, the coordinate value storage table 22, and the drawing job storage file 55 are accessed from the processing required in the program. The program and the table are stored in a portable storage medium such as an FD or a CD-ROM, and the graphic display can be easily performed by installing the program and the table when implementing the present invention.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified and applied within the scope of the claims.

[0064]

As described above, according to the present invention, in a case where a dense and large-scale drawing operation with the same intention is repeated in various aspects, the past operation can be reused to re-use the user. Can be greatly reduced. In addition, the dense and large-scale graphic obtained by this graphic display device can be updated as a whole by re-executing necessary work according to the initial value change, so that it can be used as a graphic version of a spreadsheet. it can.

Since the method of recording and re-executing the issued command is adopted, any command other than the drawing command can be added, and the versatility and flexibility are extremely high.
