Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an editing processing method and a document editing apparatus in a document editing apparatus configured to simultaneously display and edit a screen for displaying characters (sentences) and a screen for displaying line drawings (graphics). It is used in a device for creating and editing a document in which characters and line drawings are mixed, such as a device called a word processor or a graphic editor.
[0002]
Generally, in a document editing apparatus, the position of a character is represented by the position of a line and a column in a sentence on a character screen. This can be said to represent the character position in a text coordinate system different from the two-dimensional coordinates of the line drawing screen. When characters and line drawings having independent coordinate systems are displayed on the same screen at the same time, it is necessary to associate coordinates between the characters and line drawings.
[0003]
In recent years, it has become widespread to input a line drawing on a character screen by handwriting, such as drawing a comment by underlining a part of a sentence by hand, or drawing a circle by handwriting on a noticeable part of the sentence. In such a case, the relative positional relationship between the character and the line drawing is important. If the positional relationship between the two is displayed differently, the original meaning of the line drawing input is lost, resulting in an incorrect expression or an incorrect sentence. The appearance of a document editing apparatus that does not cause such inconvenience is desired.
[0004]
[Prior art]
Conventionally, there are many document editing apparatuses that can simultaneously display characters and line drawings on the same screen. They can input line drawings using a mouse, for example, and can coexist with characters input with a keyboard. There is also a document editing apparatus that allows characters and handwriting to coexist by inputting a line drawing using a tablet and a stylus pen instead of a mouse.
[0005]
In such a document editing apparatus, the arrangement position of characters is expressed by a two-dimensional coordinate system used for displaying a line drawing. In some cases, rows and columns for displaying characters are set in advance, and coordinate systems for displaying line drawings are associated with each other. In any case, the position of the entire area for displaying characters is associated with a coordinate system for displaying a line drawing. However, in such a document editing apparatus, the coordinates of the entire character and the line drawing are associated with each other, and are not associated with individual lines or characters on the character screen.
[0006]
Some conventional document editing apparatuses have a function called “anchor”. This is a function that puts a マ ー ク mark on a line in a sentence and saves the relative position between the マ ー ク mark and a line drawing. Since the マ ー ク mark moves as the text is edited, the line drawing also moves in response to the movement of the text. This haze mark is displayed only during editing and is not printed during printing.
[0007]
[Problems to be solved by the invention]
As described above, in the conventional document editing apparatus, the positional relationship between characters and line drawings is associated with each other in units of lines, but not in units of characters. Therefore, if the position of the character that should correspond to the line drawing is shifted by inserting or deleting the character in the line marked with a 錨 mark, the positional relationship with the line drawing is shifted and the display corresponds. Disappear.
[0008]
In order to solve this problem, it is conceivable to set the マ ー ク mark not in units of lines but in units of characters. However, even in this case, the following problems arise.
That is, as shown in FIG. 17A, when an underline UL81 is drawn on a character string (sentence) CH81 of “handwritten comment”, a wrinkle mark is attached to the starting end portion of the underline UL81, thereby the character string CH81. And the underline UL81 are associated with each other.
[0009]
However, when the character string CH81 “handwritten comment” shown in FIG. 17A is corrected to the character string CH82 “handwritten underline” as shown in FIG. 17B, the corrected character string CH82 is Although the length of the underline UL81 is constant despite being shorter than the character string CH81 before correction, the underline UL81 extends beyond the “handwritten underline” to the “example” part. This is clearly unsuitable for the operator's will.
[0010]
As described above, it is not sufficient that the correspondence between the characters and the line drawing is simply associated with the positional relationship in units of characters. In particular, in the case of handwritten comments, comments are often overwritten on a character string, and it is important not to break the correspondence between characters and line drawings.
[0011]
The present invention has been made in view of the above-described problem. Even when the length of a character that should correspond to the line drawing is changed due to insertion or deletion of the character, the correspondence between the positional relationship between the character and the line drawing is achieved. It is an object of the present invention to provide an editing processing method and a document editing apparatus that can be maintained.

An editing processing method according to the present invention will be described with reference to FIG.
FIG. 1B shows a state in which a handwritten underline UL1 is drawn on the character string CH2 “test” in the character string CH1 shown in FIG. By drawing the underline UL1, the character markers MC1 and MC2 are generated in the middle between the characters at positions close to the start point PEs and the end point PEe of the underline UL1.
[0016]
One character marker MC1 stores the positional relationship with the starting point PEs of the underline UL1, and the other character marker MC2 corresponds with the positional relationship with the end point PEe of the underline UL1. It is a thing to remember. These character markers MC have pointers indicating the positional relationship between the two characters on both sides thereof. That is, here, the two characters on both sides of the character marker MC correspond to “specific characters” of the present invention, and the start point PEs and the end point PEe correspond to “specific two points” of the present invention.
[0017]
As shown in FIG. 1C, when the character string CH2 “test” is changed to the character string CH3 “test”, the position of the character marker MC2 moves to the left by one character.
The underline UL2 is displayed in accordance with the positional relationship because the start point PEs is associated with the character marker MC1 and the end point PEe is associated with the character marker MC2.
[0018]
At that time, in order to match the distance between the start point PEs and the end point PEe by one character, a deformation process for shortening the underline UL1 is performed.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram for explaining an editing processing method according to the present invention.
FIG. 1 shows a character string CH and an underline UL1 displayed on the screen of a document editing apparatus (not shown). The square frame displayed for each character in FIG. 1 explains the position of the character marker MC. Is not intended to be displayed on the screen. Further, the character marker MC is not displayed on the screen.
[0020]
As shown in FIG. 1A, a character string CH1 “This is a test” is displayed on the screen. FIG. 1B shows a state in which a handwritten underline UL1 is drawn on the character string CH2 “test” in the character string CH1. By drawing the underline UL1, the character markers MC1 and MC2 are generated in the middle between the characters at positions close to the start point PEs and the end point PEe of the underline UL1.
[0021]
One character marker MC1 stores the positional relationship with the starting point PEs of the underline UL1, and the other character marker MC2 corresponds with the positional relationship with the end point PEe of the underline UL1. It is a thing to remember. These character markers MC have pointers indicating the positional relationship between the two characters on both sides thereof, and are thus associated with the positions of the two characters on both sides.
[0022]
The data of the character string CH1, the data of the character markers MC1 and 2, the data of the underline UL1, and the data of the start point PEs and the end point PEe are stored in the edit memory area of the document editing device.
[0023]
Therefore, as shown in FIG. 1C, when the character string CH2 “test” is changed to the character string CH3 “test”, the position of the character marker MC1 is not changed, but the position of the character marker MC2 is one character. Move left one minute.
[0024]
That is, the character marker MC1 is associated with “te”, which is the first character of the character string CH2, and “ha”, which precedes it, and the character marker MC2 is “to”, which is the last character of the character string CH2, and “ Therefore, after the character string CH2 “test” is changed to the character string CH3 “test”, the character marker MC1 is “test” which is the first character of the character string CH3 and the previous one. The character marker MC2 is associated with “experiment”, which is the last character of the character string CH3, and then “de”.
[0025]
The underline UL2 is displayed according to the positional relationship because the starting point PEs is associated with the character marker MC1 and the terminal point PEe is associated with the character marker MC2. At this time, the position of the character marker MC2 is moved to the left by one character, and as a result, the distance between the start point PEs and the end point PEe is shortened by one character, so the length of the underline UL2 is adjusted to that. Therefore, a deformation process for uniformly shortening the underline UL1 is performed. For the deformation process of the underline UL1, various known processes are performed. For example, when the underline UL1 is stored as vector data, the feature point of the underline UL1 is moved according to the position ratio.
[0026]
As described above, when the character string CH2 “test” is changed to the character string CH3 “test”, the underline UL1 is shortened to the underline UL2 as shown in FIG. 1C, and the character string CH3 “test” is displayed. Will be drawn correctly in response to.
[0027]
FIG. 2 is a diagram for explaining another example of the editing processing method according to the present invention. In FIG. 2, the frame representing the character position is deleted. The character marker MC is indicated by a small triangle.
[0028]
As shown in FIG. 2A, a character string CH1c “This is an example of a handwritten comment” is displayed on the screen. As shown in FIG. 2B, when the underline UL3 is drawn in the character string CH4 “handwritten comment” therein, character markers MC3, 4 are generated at positions close to the start point and end point of the underline UL, respectively. . When the character string CH4 “handwritten comment” is changed to the character string CH5 “handwritten underline” as shown in FIG. 2C, the position of the character marker MC4 moves, and the underline UL3 is shortened corresponding to the position. The underline UL4 is drawn corresponding to the character string CH5 “handwritten underline”.
[0029]
FIG. 3 is a diagram for explaining another example of the editing processing method according to the present invention.
As shown in FIG. 3A, a character string CH1d “This is an example of a handwritten comment” is displayed on the screen. As shown in FIG. 3B, when underlines UL5, 6, and 7 are respectively drawn in the character strings CH6, 7, and 8 "examples of handwritten comments" therein, the start and end points of each underline UL are displayed. Character markers MC5, 6, 7, and 8 are generated at positions close to each other. When the “example of character string CH8” is deleted as shown in FIG. 3C, the positions of the character marker MC8 and the character marker MC0 overlap. Therefore, the underline UL7 disappears, and the other underlines UL5, 6 are drawn corresponding to the remaining character strings CH6, 7 "handwritten comment".
[0030]
As described above, even if one continuous underline is greatly different, it can be processed as separate underlines.
FIG. 4 is a diagram for explaining another example of the editing processing method according to the present invention.
[0031]
As shown in FIG. 4A, a character string CH1f “This is an example of a handwritten comment” is displayed on the screen. As shown in FIG. 4B, when an underline UL8 is drawn on the character string CH9 “handwritten comment” therein, character markers MC9 and MC10 are generated at positions close to the start point and end point of the underline UL8, respectively. . As shown in FIG. 4C, it is assumed that a character string CH10 “when a sentence is broken” is inserted into the character string CH1f, and the character string CH1g becomes a two-line character string. Then, the position of the character markers MC9, 10 moves in the horizontal direction and the line position of the character marker MC10 moves accordingly, but the correspondence between the start point and the end point of the underline UL8 does not change, so the underline UL8 is It is drawn correctly corresponding to the character string CH9 “handwritten comment” divided into two lines.
[0032]
Next, an embodiment of the document editing apparatus 1 will be described.
FIG. 5 is a block diagram of the document editing apparatus 1 according to the present invention, FIG. 6 is a diagram showing a configuration of text data cells CL stored in the text data storage unit 24, and FIG. 7 is a diagram showing a configuration of character markers MC. FIG. 8 is a diagram showing the configuration of the marker movement information DMM, and FIG. 9 is a diagram showing the configuration of the graphic marker MF.
[0033]
The document editing apparatus 1 includes a text editing unit 11 that edits text data composed of characters, a graphic editing unit 12 that edits graphic data (line drawing data), and a character screen and a graphic (line drawing) formed of characters. It consists of a display unit 13 capable of displaying a graphic screen in an overlapping manner at the same time.
[0034]
The text editing unit 11 only edits text portions in the document. The graphic editing unit 12 edits only the graphic. Image data obtained as a result of editing in the text editing unit 11 and the graphic editing unit 12 is output to the display unit 13 and displayed superimposed on the same screen. The method of superimposing the character screen and the graphic screen is determined based on the positional relationship data held by the display unit 13.
[0035]
The text editing unit 11 includes an input unit 21, a text deletion / insertion unit 22, a pointer operation unit 23, a text data storage unit 24, a pointer storage unit 25, a character marker storage unit 26, and the like.
[0036]
The input unit 21 outputs various commands such as pointer movement, character deletion, and character insertion based on a keyboard or mouse operation (not shown). When a character is inserted, the code of the character to be inserted is output. For example, when a character key such as an alphanumeric character or a symbol on the keyboard is pressed, the code of the character is output. When the arrow key is pressed, a command to move the pointer position is output, and the delete key is pressed. If so, it outputs a command to delete characters.
[0037]
Text data is stored in the text data storage unit 24. In the text data, at least during editing, each character is stored in a cell CL shown in FIG. In FIG. 6, a cell CL includes data content DCT, a pointer PTB indicating the address of the previous cell, and a pointer PTA indicating the address of the subsequent cell.
[0038]
That is, the position of the character to be edited in the text data stored in the text data storage unit 24 is stored in the pointer storage unit 25 as a pointer. The pointer stored in the pointer storage unit 25 is data indicating a position in a sentence such as “nth character in text”. Usually, the pointer is expressed by the position of the cursor on the screen. The text data is edited with reference to this pointer.
[0039]
Editing of text data is performed by sequentially executing various processes such as a process of deleting a character at a position indicated by a pointer or a process of inserting a new character at the position. What processing is performed depends on a command from the input unit 21.
[0040]
Also, the position of the pointer in the text data can be changed by a command from the input unit 21. The pointer position is changed by changing the value of the pointer stored in the pointer storage unit 25 by the pointer operation unit 23.
[0041]
The graphic editing unit 12 includes an input unit 31, a graphic deletion insertion moving unit 32, a pointer operation unit 33, a graphic data storage unit 34, a pointer storage unit 35, a graphic deformation moving unit 36, a graphic marker storage unit 37, and the like. ing.
[0042]
The input unit 31 is connected to a coordinate input device such as a stylus pen and tablet (not shown), a mouse, a keyboard, and the like. Based on these operations, the input unit 31 outputs various commands such as pointer movement, figure deletion, figure insertion, and figure movement.
[0043]
The principle of graphic data editing in the graphic editing unit 12 is the same as that of the text editing unit 11. The graphic data storage unit 34 stores graphic data as vector data, for example. Each graphic data has a graphic ID (IDF) for identifying the graphic. The position of the graphic to be edited in the graphic data stored in the graphic data storage unit 34 is indicated by a pointer stored in the pointer storage unit 35. In accordance with a command input from the input unit 31, editing processing such as deletion, insertion, and movement of the data is performed.
[0044]
There are some parts of the graphic editing unit 12 that are different from the processing of the text editing unit 11. For example, although the pointer stored in the pointer storage unit 35 is the position to be edited, two-dimensional coordinates on the plane on which the figure is drawn are stored. The graphic data stored in the graphic data storage unit 34 is represented by a set of graphic objects, such as a straight line, a curve, a polygon, and a circle. Each graphic object has a position in two-dimensional coordinates.
[0045]
For example, when the figure is a triangle, the upper left point of the figure is a point representing the entire position of the figure object. When the figure is a line, the leftmost point of the figure is a point representing the entire position of the figure object. When the coordinate point of the pointer stored in the pointer storage unit 35 coincides with the position of any graphic object, the pointer indicates the graphic object with the matched position. If there is no graphic object whose position matches, the pointer indicates the coordinate point itself.
[0046]
When a command to delete or move a graphic is output from the input unit 31, the graphic object pointed to by the pointer stored in the pointer storage unit 35 is deleted or moved. If the pointer does not indicate anything, do nothing. When a figure insertion command is output from the input unit 31, the designated figure is inserted at the coordinate position indicated by the pointer. These data editing processes are performed by the graphic deletion insertion moving unit 32. When the pointer movement key is pressed, the pointer is moved to the position designated by the coordinate input device by the pointer operation unit 33.
[0047]
The above-described components and processing contents in the document editing apparatus 1 are the same as those of a known document editing apparatus. Next, processing unique to the editing processing method according to the present invention will be described.
[0048]
The document editing apparatus 1 according to the present embodiment is particularly provided with a character marker storage unit 26, a graphic marker storage unit 37, and a graphic deformation moving unit 36 in order to perform editing processing according to the present invention. The marker movement information DMM is passed from 11 to the graphic editing unit 12.
[0049]
In the text editing unit 11, the character marker storage unit 26 stores a character marker MC for defining the positional relationship between characters and graphics. When the text document is edited, the position of the character marker MC may be changed. In this case, the marker movement information DMM is sent from the character marker storage unit 26 to the graphic transformation moving unit 36 of the graphic editing unit 12. Is output.
[0050]
As shown in FIG. 7, the character marker MC includes data contents DCT, a pointer PTB indicating the address of the previous cell, a pointer PTA indicating the address of the subsequent cell, and a row and a column indicating the position of the character marker MC in the text coordinate system. Number VLC, and a coordinate VCD indicating the position of the character marker MC in the two-dimensional coordinate system. That is, the basic configuration of the character marker MC is the same as that of each character cell CL in the text data, and the row and column numbers VLC and the coordinates VCD are added thereto. The character marker MC is automatically generated between a character and a character close to a reference point (specific point) of the figure by writing the figure on a screen displaying text data.
[0051]
In this way, the character marker MC is provided in the middle of two characters, and each character is associated with the character marker MC when the character marker MC is deleted when it is associated with only one character. This is because the position is lost.
[0052]
As shown in FIG. 8, the marker movement information DMM includes a character marker ID (IDC) for identifying a related character marker MC, a coordinate VCE of the character marker MC before movement, and a coordinate VCF after movement.
[0053]
In the graphic editing unit 12, the graphic deformation moving unit 36 compares the marker movement information DMM with the graphic marker MF stored in the graphic marker storage unit 37, and resets the coordinate VCD of the character marker MC to the coordinate VCF after the movement. Set. Further, it is checked whether there is a figure to be deformed or moved by changing the position of the character marker MC, and the existing figure is moved or deformed as necessary.
[0054]
As shown in FIG. 9, the graphic marker MF includes a graphic ID (IDF) for identifying a related graphic, a character marker ID (IDC) for identifying a related character marker MC, a character marker MC, and a graphic reference. It consists of a distance DST indicating the distance between the points and the coordinates VCD of the associated character marker MC.
[0055]
Next, an example of the movement / deformation process of the graphic in the graphic editing unit 12 and the expansion / contraction process when the graphic is underlined will be described with reference to the flowcharts shown in FIGS. 10 and 11.
[0056]
First, the marker movement information DMM is input (# 11). Based on the marker movement information DMM, the moved character marker MC is listed. The graphic associated with the moved character marker MC is moved or deformed accordingly. Therefore, the figures to be moved or deformed are listed (# 12).
When there are a plurality of character markers MC for one figure, the figure is deformed when the positional relationship between the plurality of character markers MC changes. Therefore, a change in the positional relationship of the plurality of character markers MC related to one graphic is detected (# 13, 14), and the graphic is deformed as necessary (# 15). Further, the entire position of the figure is moved as necessary (# 16).
[0057]
In the expansion / contraction process, first, the line numbers between a plurality of related character markers MC are checked (# 21, 22), and if the line number difference is changed, it is determined that the sentence is folded by editing the text data, The underline associated with the sentence is similarly folded (# 23).
[0058]
Further, it is checked whether there is a change in the spacing in the line direction of the text between the plurality of character markers MC (# 24), and if there is a change, the underline is expanded or contracted accordingly (# 25).
[0059]
Whether or not the character string CH is folded in the middle, that is, whether or not a line break has occurred, can be determined by examining the y-coordinate of the coordinates VCD of the character marker MC. This is because the y-coordinates are the same when they are in the same row. Further, by examining the difference of the y-coordinates, it can be understood how many lines are folded back in the middle of the underline UL.
[0060]
When the line is folded, the distance between the two character markers MC (difference in x coordinate) cannot be calculated simply by the value of the x coordinate. For example, if the start point PEs is on the right side of the end point PEe, simply taking the x coordinate difference will result in a negative value. Therefore, the correct x-coordinate difference can be obtained by adding the width of one line of the sentence by the number of foldings to the x-coordinate difference before the folding. The length of the underline UL is expanded / contracted according to the change of the x coordinate thus obtained, and is adjusted to the position of the character marker MC at the start point PEs. Next, the underline UL is cut at the position where the line is folded, and the remaining part is moved to the head of the next line. Repeat as necessary.
[0061]
Whether or not the figure is underlined is determined based on a command from the operator, but may be automatically determined.
Next, a specific example of processing in the document editing apparatus 1 will be described in the case where the document editing processing shown in FIG. 1 is performed.
[0062]
12 is a diagram showing an example of the cell CL1 and the character markers MC1 and MC2 for the character string CH1 shown in FIG. 1B, and FIG. 13 is a diagram showing the positional relationship between the character markers MC1 and MC2 and the underline UL1 in FIG. 14 is a diagram showing an example of the contents of the graphic marker MF2 before and after the movement, FIG. 15 is a diagram showing an example of the contents of the character marker MC2 after the movement, and FIG. 16 is a diagram showing an example of the contents of the marker movement information DMM1. is there.
[0063]
As shown in FIG. 12, a character string CH1 “This is a test” is displayed on the screen, and a handwritten underline UL1 is drawn on the character string CH2 “Test”. By drawing the underline UL1, two character markers MC1 and MC2 are generated in the middle of the character and at a position close to the start point PEs and the end point PEe of the underline UL1. Two graphic markers MF1 and MF2 are generated.
[0064]
The character string CH1 is managed as one independent sentence, and the first character in the character string CH1 is the first row and the first column. Here, it is assumed that one character is composed of 16 × 16 dots, and there is no space between characters.
[0065]
The character marker MC1 is located between the characters “ha” and “te”, and the character marker MC2 is located between the characters “g” and “de”. In the cell CL1 for the character “ha”, the code data “ha” is stored in the data content DCT, the address indicating the cell CL “re” is stored in the pointer PTB, and the address indicating the character marker MC1 is stored in the pointer PTA. ing.
[0066]
The character marker MC1 includes data indicating that the data content DCT is the character marker MC1, an address indicating the cell CL of “ha” in the pointer PTB, an address indicating the cell CL of “te” in the pointer PTA, “1, 3” indicating the first row and third column is stored in the column number VLC, and “48, 16” is stored in the coordinate VCD.
[0067]
In the character marker MC2, the data content DCT indicates that the data is the character marker MC2, the address indicating the “CL” cell CL in the pointer PTB, and the address indicating the “CL” cell CL in the pointer PTA, “1, 6” indicating the first row and sixth column is stored in the row and column numbers VLC, and “96, 16” is stored in the coordinate VCD. That is, the respective coordinates VCD of the character markers MC1 and MC2 are the coordinates of the lower end point of the boundary portion between the characters on both sides.
[0068]
As shown in FIG. 13, the underline UL1 is represented by vector data having several intermediate points PM between the start point PEs and the end point PEe. The two graphic markers MF1 and MF2 include a distance DST (dx, dy) between the start point PEs and the coordinate VCD of the character marker MC1, or a distance DST (dx, dy) between the end point PEe and the coordinate VCD of the character marker MC2. Is memorized.
[0069]
For example, as shown in FIG. 14A, the graphic marker MF2 includes data for identifying the underline UL1 as the graphic ID, data for identifying the character marker MC2 as the character marker ID, and the terminal point PEe and the character at the distance DST. Coordinates representing distances from the coordinates VCD of the markers MC2 are stored in the coordinates VCD, respectively.
[0070]
