JPS61107467A - Specification method of framing for character-graphics editing device - Google Patents

Abstract

PURPOSE:To facilitate graphics processing by performing automatic framing specification based on quantity of characteristics of graphics data drawn by graphics identification processing when the graphics data is inserted into character data. CONSTITUTION:When graphics data with coordinate specification and character data with handwriting characters are entered from an entry unification display consisting of an electromagnetic tablet 1, stylus pen 2, and flat display 3a, etc., they are recognized by a character-graphics recognition processing section 41 in a processing unit 4, and graphics editing operation information is sent a framing processing section 42, a sheet being allocated to a graphics area and character area. The current cursor position is decided in an area decision section 44 of a editing processing section 43 according to that allocation. If it is a character area, one-dimentional editing processing 45 is done. If it is a graphics area, two-dimensional editing processing 46 is done.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a character/figure editing device, and particularly to a frame/empty designation method for effectively specifying a frame/empty designation.

[Background of the invention]

With the progress of OA, especially word processors (word processors)
is developing greatly. Recently, not only strings,
It is becoming highly functional, with the ability to insert charts and tables. but,
When inserting figures and tables, please refer to the document "NewtOn Separate Volume All About Word Processors" (857, 5, 20) pl 51
As shown on page 152, I first specified the frame opening and created a blank space before drawing. This frame opening designation is far removed from the original work format, which allows the operator to input characters or charts on a sheet without being aware of it. Additionally, handwritten word processing products that make full use of online handwritten character recognition technology have recently begun to appear. This handwritten word processor works in the same way as the traditional paper-and-pencil method, so input can be made without interrupting human thought, making it much more man-machine-friendly than keyboard input. However, if you can input the diagram, and
Until now, there has been no proposal for a method for effectively editing characters in diagrams.

[Object of the Invention] The object of the present invention has been made in view of the above-mentioned drawbacks, and relates to a frame-empty designation method for automatically specifying the frame-empty designation of a text/graphic printing device.

[Summary of the invention]

Is the frame empty specified for a shape or table? Specify that area to create and roll to do different management with strings. Therefore, by making full use of the two-dimensional information of the diagram, that is, the properties of the area, when a figure or table is input, the area below it is automatically designated as the figure area, as a feature quantity. Furthermore, when characters or figures in a figure area are edited, the two-dimensional information is naturally edited. Therefore, the present invention is characterized in that the graphic area is completely redefined based on all the operation data used for this editing.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 10.

(1) Overview of one embodiment of the present invention
;; FIG. 1 is a block diagram of an embodiment of the present invention, and is a block diagram of a handwritten word processor using online handwritten character/figure recognition processing. 1 and 2 are coordinate input devices, for example, 1 is an electromagnetic tablet, 2 is a stylus pen, and 3 is a flat display, such as a liquid crystal display.
has a laminated structure. This is called an integrated input display, and it replaces the role of traditional paper and pencil. In other words, when you input coordinates with a stylus pen, your handwriting appears on the display. Reference numeral 4 denotes a processing device, which can be composed of, for example, a 16-bit microcomputer. The inside of the processing device is made up of blocks 41 to 43, 41 is an online character/figure recognition processing section, 42 is a frame processing section, 43 is an editing processing section, and the editing processing section 43 is an area determination processing section 4.
4. It consists of a one-dimensional character string editing processing section 45 and a two-dimensional character/graphic editing processing section 46.

An outline of the operation shown in Fig. 1 is shown below. When a stroke is input to the integrated input display consisting of 1 to 3, characters are recognized and graphics are encoded through figure recognition processing, and the results are displayed in neat form on the integrated input display. At this time, strokes (handwriting) are also erased at the same time. For details on online character/figure recognition, see Japanese Patent Application Laid-Open No. 49-5
This is disclosed in Japanese Patent Application Laid-open No. 5236 and Japanese Patent Application Laid-open No. 159363/1983, and detailed explanation thereof will be omitted.

Based on the figure information of the code output of the character/figure recognition processing section 41 and the figure editing operation information when figure editing operations are performed from the input integrated display, for example, operation information such as moving figures 9 enlarging and reducing figures, etc. Then, the empty frame is processed. The processing unit defines the allocation of what is managed in the sheet t-1 dimension to the character (text) area and what is managed two-dimensionally to the graphic area. FIG. 2 shows the sheet layout when a figure is input. The entire area of the sheet before inputting figures is defined as a character (text) area. In that state, input the shape (see Figure 2 (
a)) Calculate the figure area based on the X-axis and Y-axis projected length of the figure, define one figure area GAt as shown in Figure 2, and text areas TA and TB.

Defined in three rectangular parts of TO.

When the frame empty processing is completed, characters and figures are edited in block 43. The processing mode changes depending on which area the coordinates (or KANO J/) of the object to be edited are located. If it is a character (text) area, one-dimensional editing processing is performed, and if it is a graphic area, two-dimensional editing processing is performed. The results of the editing process will not be displayed on the input integrated display.
Ru.

Figure 3 shows the coordinates of the area when the empty frame is specified in Figures 2 (a) and (b), and these coordinates are shown in Figure 4 (
It is stored in the tables a) and (b) and used when editing. In Figure 3, the character (text) areas are TA, T
It is divided into three parts (B, TC), but if these are connected from top to bottom and from left to right, then when one area is full, the text will be transferred to the next area. (string)
is being packed.

That is, the character (text) area is connected to TA-4TB-'I'C, as shown in FIG.

FIG. 4(a) shows character (text) areas TA and TB.

In the TC management data, T 几NO is the number of character (text) areas, TxOm~TYIm is data for one character (text) area, TxOm~TY1i is TB data, T
X Oc to T Y 1 c indicate TC data. Further, FIG. 4(b) shows the management data of the graphic area GA, GR
NO indicates the number of graphic areas, and GXOA to GYI□ indicate data of the graphic area GA.

FIGS. 5 and 6 are explanatory diagrams for generating an area with an empty frame from graphic editing operation information, and show a case where a part or all of a graphic is copied. As shown in FIG. 5(a), if a part of the graphic data in the graphic area GA is to be copied to the lower left as shown in the figure, the graphic area is enlarged to GA'. This data becomes as shown in FIG. 5(b). On the other hand, as shown in FIG. 6, when the coordinates of the figure to be copied (destination operation coordinates) do not overlap with the figure area GA, yet another figure area GBt is defined. The area data in this case is as shown in FIG. 6(b). Of course, in Figures 5 and 6,
Needless to say, data in the character (text) area is also changed.

In Figure 7, there are 0 other examples, and the figure data input button is pressed.
;; If the entire sheet is defined as a graphics area, of course there will be no character (text) area. Therefore, all character strings in the diagram are managed two-dimensionally.

Next, the concept of the one-dimensional editing section 45 and two-dimensional editing section 46 described in the editing processing section of block 43 in FIG. 1 will be explained with reference to FIGS. 8 and 9. Figures 8(a) and (b) are
In an example of one-dimensional editing of characters in the text area TA, Fig. 8(a) shows the character strings [exist], ■..., ■ being managed in a one-dimensional table, and the character strings [exist], ■..., ■ are managed in a one-dimensional table, and the characters are When a character is added, the character is displayed on the left edge of the bottom box. Therefore, as shown in FIG. 8(a), ■, 0.
If you edit by deleting the three characters 0, ■ as shown in Figure 8 (b)
, 0.0 characters are deleted, and [F], [F], ・
..., ■ are packed and processed as shown in the figure. on the other hand,
Examples of two-dimensional editing are shown in FIGS. 9(a) and 9(b)K. Two-dimensional editing is specified when the area is determined to be a graphic area and a graphic (including a table) is input. As shown in FIG. 9(a), the inside of the rectangle is defined as the graphic area GA,
Character string ■ in the diagram.

■, ..., if there is O, ■, ■, [F],
When you delete and edit the character [F], as shown in Figure 9(b), the character string is managed two-dimensionally, that is, horizontally (X-axis) and vertically (Y-axis), so the deleted character becomes ■ , ■, @.

[F] does not affect other character strings O, Q, G, and θ. That is, the deleted character is replaced with a blank space. Of course, since figures are represented in quadratic terms, they are managed two-dimensionally.

You can edit text and figures by specifying the menu command and then specifying the editing range of the text and figures (APPLE computer, Lisa, etc.), or by directly writing objects using JIS proofing marks, etc. How to specify (Information Processing Society of Japan/Computer Architecture - Research Materials Tomb 49p1~
I) 10-1983°6.3) has been proposed, so detailed explanation will be omitted.

(2) Detailed explanation of the processing shown in the blank box. FIG. 10 shows the processing flow of the processing unit 42 in the blank box in FIG.

The empty frame process is the definition of a graphic area within a character (text) area. In one embodiment of the present invention, a processing flow when a graphic area definition is generated from input graphic information and graphic editing operation information is shown below.

First, check whether there is a figure input (Step 42
A) L: If there is, define a graphic area from the input graphic.

That is, the figure is input in step 42B, and the figure is input in step 4.
In steps 2C, 42D, and 42E, a graphic area is defined from the Y-axis of the graphic and the projected length on the Y-axis, and the areas of all the figures are compared to determine the graphic area.

Next, check if there is any editing within the graphic area obtained above (
Step 42F). This check can be easily determined by checking whether the coordinates for the editing operation are within this graphic area. If there is no editing in step 42F, the text area is redefined and the process ends. On the other hand, when there is editing, the graphic area is redefined by the editing operation in steps 42G to 42M. First, it is determined whether the area after editing, for example, the destination area when copying and editing a figure, overlaps with the figure area defined when inputting the figure (step 42G).
). If there is no overlap, Figure 6(a)
Define another graphic area in cases like (
step 42J).

On the other hand, in the case where the regions overlap, as shown in FIG. 5(a), the previous graphical region is further modified and defined as OA' (steps 42H and 42J). Additionally, if there is area overlap between a plurality of graphic areas, the graphic areas are similarly redefined (step 42K).

42L). The above process is continued until all T edits are completed (step 42M). Finally, the text area is redefined in accordance with the increase or decrease in the graphic area, and the process ends (step 42N).

Through the above processing, the definition of the text area and figure area within the sheet is completed, and editing of characters or figures is processed for each area as described above in Figure 1 (see Figures 8 and 9). )
.

(3) Effects of the embodiment of the present invention According to the embodiment of the present invention, conventionally, when a figure is
It is necessary'fc-h2 specified 0 operation is a < X
,,.

Operators can input characters and figures on the sheet without interrupting their thinking, improving operability. In particular, when editing a figure, the processing device automatically defines the frame, so that it is possible to operate the empty frame without having to worry about changing the designation. In addition, in one embodiment of the present invention, the integrated input display and online handwriting technology make the work style similar to the conventional paper and pencil method, greatly improving man-machine performance.

(4) Other Embodiments of the Present Invention As another embodiment of the present invention, as described above in FIG. 7, when a figure is input, the entire sheet is set as a figure area.
There is also a method for editing all character strings in two dimensions. This method is effective when creating a document with many figures, but since the character strings are not managed one-dimensionally, the character strings are not automatically arranged. This corresponds to the traditional desk-based eraser or cutting and pasting using scissors.

〔Effect of the invention〕

As described above, according to the present invention, when inputting a figure, the empty frame does not have to be touched by fingers, which has the effect of greatly improving man-machine performance.
