In such a way, the hidden character-string becomes visible.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a document processing device, and more particularly to a document processing device that creates and edits documents.

[Conventional technology]

In recent years, desktop publishing (so-called DTP) using computers and the like has been desired. Normally, when creating a document in this type of system, an operation is performed in which characters input from a keyboard or the like are expanded into each frame in which the document is expanded.

[Problem to be solved by the invention]

By the way, in this DTP, it is desired to rotate characters in a free direction without having to write vertically or horizontally, or to erect an image. Moreover, even if frame rotation is realized, problems remain. In other words, the rotation often hides a part of the other frame that was previously visible. The present invention has been made in view of such prior art, and it is an object of the present invention to provide a document processing device that allows character strings that would otherwise be hidden by rotating a frame to be rearranged and made visible.

[Means to solve the problem]

In order to solve this problem, the document processing device of the present invention has the configuration shown below. That is, a document processing device that creates and edits a document by expanding and displaying a character string or an image in at least one frame set within a page, comprising: a rotation means for rotating a desired frame; a detection means for detecting whether or not there is a frame having a character string hidden by part or all of the frame rotated by the rotation means; and character string arrangement means for rearranging character strings so as to avoid the frame rotated by the rotation means.

[Effect]

In this configuration of the present invention, a desired frame is rotated by the rotating means. Then, the detecting means detects whether there is a frame having a character string that is partially or completely hidden by the rotated frame. Then, the character string within the detected frame is rearranged by the character string arrangement means so as to avoid the rotating frame.

【Example】

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. <Description of System Configuration> FIG. 1 is a block configuration diagram of a document processing system in an embodiment. In the figure, 1 is a CPU that controls the entire system, and 2
is a ROM that stores the boot program at the time the device is powered on, and 3 stores programs read from an external storage device (such as programs related to the flowchart in Figure 6.10 described later) and document information being edited. , C
This is a RAM used as a work area for PU1. 4 is a font memory (stores so-called outline fonts) that stores coordinate format data for generating character patterns; 5 is a VRAM that develops images to be displayed on the display screen; and 6 is the VRAM-5. This is a CRT display that displays an image developed on the screen. Reference numeral 7 denotes a magnetic storage device, typically a floppy disk device or a hard disk device, which stores various programs (loaded into the RAM 3) related to document processing in this device, document information, and the like. 8 is a keyboard for giving predetermined instructions to the characters composing the document or this system; 9 is C;
This is a mouse for controlling the movement of a graphic cursor displayed on the display screen of the RT display 6. Reference numeral 10 denotes an image memory capable of developing an image for one page of SP recording paper when the stage of actual printing processing is reached; reference numeral 11 forms a visible image on a recording medium based on the image developed in the image memory 10. It's a printer. The printer 11 in this embodiment will be described as a laser beam printer. Usually, CRT display devices only need to be able to confirm the edited content, so their resolution is lower than that of high-quality printers such as laser beam printers. When performing printing processing, character patterns and the like matching the resolution of the printer are generated in accordance with the document information to be printed, according to the data read out from the font grid 4, developed in the image memory 0, and printed. Explanation of Frame> FIG. 2 shows an example of the layout of a frame that is a development area of a document in the embodiment. In the figure, 20 represents recording paper, and 21 to 23 represent each character string (
This is a frame for expanding documents. The size and settings of the frame are performed by operating the mouse 9. Specifically, by operating the mouse 9, you can freely scroll the recording paper displayed on the display screen, move the graphic cursor to any two points within it, and press the button provided on the mouse 9. Press (hereinafter referred to as "click"). These two points are taken as the end points of the diagonal of the rectangle (=frame). After this, a document is created by specifying an appropriate frame using the mouse, etc., and expanding the character string input from the keyboard 8 (hereinafter, in the example, a single character is included) into the frame. . Note that even after inputting a document or the like, the layout and size of the frame can be changed freely. In the above configuration, multiple frames are set within each page, and a document is created by expanding character strings entered manually using the keyboard 8 (at this time, however, the RAM 3 contains data as shown in Figure 3). In the figure, 31-1.2...n indicates information on each page (hereinafter referred to as page information).As you can see from the page information 31-1 of the first page, In the example,
Data for one frame is composed of three pieces of information: a frame header area 32, a character code area 33, and a character attribute area 34. Each area will be explained below. The frame header area 32 stores data necessary for editing the frame. In the embodiment, this frame header area contains information as shown in FIG. , and an area for storing its attribute information.The frame number is a number to distinguish the frame of interest from other frames, and no two frames have the same number.This is because, for example, when an operator selects a frame, Every time you set a new one, you just need to increment it by one. Link information is information that specifies the frames that logically precede and follow the spout frame. In other words, which frame is the frame you are looking at? Each frame number is stored to indicate which frame is the one that follows the frame of interest and which frame is the next one after the frame of interest.Furthermore, if there are no frames to be connected before or after, a number that cannot exist (for example, , “O”, etc.). Incidentally, both “
O", the frame of interest is an isolated frame. Also, the size, coordinate position, and number of characters are as described above. In addition, in the device of the embodiment, each frame is an isolated frame. If it is placed parallel to the frame, it can be rotated in 1 degree increments.The value is stored in the rotation angle.Finally, regarding the attribute information of the frame header, it is possible to rotate it in units of 1 degree. Attribute name information that allows the operator to add simple comments, document layout information such as whether the document in the frame is written vertically or horizontally, font size information (number of points), character vertical and horizontal magnification information, and Roman characters. typeface information (for kanji, Mincho or Gothic; for European characters, Fourier, Herbetica, Times, etc.), distance information between lines,
It is composed of inter-character distance information, angle information of italic characters, information on the presence or absence of prohibition processing, information indicating whether the information in the frame is text or an image, etc. The attributes of this frame header are set to default values unless the operator actively instructs to change each piece of information. Note that when the information in the frame is an image (read by an image scanner), the image data is stored in the illustrated character code area. Although the explanation will be repeated later, when the operator sets a frame, first, an area for the frame header, a character code area, and a character attribute area are each secured in the RAM 3. Next, in the character code area in FIG. 3, individual character codes constituting the document developed within the corresponding frame are stored. However, if the information within the attention frame is an image, the character attribute area 34 is not generated, as a matter of course. Further, the character attribute area 34 stores attribute information for each character in the corresponding character code area. There are various types of attribute information for individual characters, but
To name a few, font size information, font type (type of font), decoration information (color of font decoration, presence or absence of underlining, presence or absence of overline, presence or absence of shading, and the shading is the type of pattern, the information surrounding the character string. information on the presence or absence of enclosing ruled lines, etc.), character shape information, character color, vertical position of characters, character spacing, and information on whether to invert the display pattern. Among these, there are two types of glyph information: front characters and shadow characters. For front characters, double the width (50-200% range) and double the height (50-20%).
00% range), presence/absence of border, angle of italic, direction of italic, rotation direction (range of 0 to 360 degrees), and type of fill pattern. Information for setting almost the same parameters as for front characters is also secured for shadow characters. According to the above explanation, it may seem that the attribute information in the frame header area and the information in the character attribute area for each character overlap, but this is not the case. That is,
In the system of the embodiment, information in the character attribute area is given priority over attribute information in the frame header area. In other words, 1
Most of the attributes for the two frames are controlled by the attribute information in the frame data area, and the output form for each character, such as a request to make only this character larger, in the frame is controlled by the information in the character attribute area. control based on <Description of character avoidance processing by frame rotation> As explained above, each corner of the embodiment can have individual rotation angle information. To rotate a frame, first, use the mouse 9 to specify the frame to be rotated. After specifying this frame, the operator gives an instruction to rotate the frame. In the embodiment, this rotation processing method uses the mouse 9
There are two methods available: determining the rotation angle according to the operator's sense, and inputting the rotation angle as a numerical value using the keyboard 8, etc. After setting the zero rotation target frame, select one of these methods. . If the method of inputting the angle value using the keyboard 8 is selected, it is sufficient to simply input the value. In addition, if you select to rotate the mouse 9 arbitrarily, as the mouse 9 moves, only the outline of the half frame will be drawn and updated at any time, allowing the operator to check how much it has been rotated. . Then, the angle of the outline that was being displayed when it was clicked is set as the rotation angle of the frame of interest. After the rotation angle is determined in this way, the data is stored in the "rotation angle" column provided in the frame header information in the frame of interest. Then, if the frame is an image, etc.,
The well-known rotation equation of the following formula, (夛) ” (2)
Company 7 g) Calculate the new coordinate position of each dot based on (夛： ) and perform rotation processing on the entire image. however,(
xo, yo) are the dot coordinates before rotation, θ is the rotation angle, (
x, y) are the coordinates after rotation. In addition, when the frame of interest consists of character information, a new character pattern is generated according to the rotation angle, and the information (character (including pitch, font size, etc.). A detailed outline of frame rotation using the mouse 9 will be explained with reference to FIG. First, by moving the graphic cursor 53 linked to the mouse 9 on the screen, the center of the frame 51 is set as the center of rotation, and its outline! The display of I52 is updated as shown. The operator determines the rotation angle of the frame 51 by clicking, for example, in the illustrated state. Then, it becomes possible to obtain the result shown in the illustrated frame 51'. The operation processing contents of the CPUI will be explained according to the flowchart shown in FIG. When the operator specifies one frame by operating the mouse 9, the CPU first performs processing related to the frame specification in step S1. Specifically, it is based on the coordinate position of the graphic cursor at the time the mouse 9 is clicked, and from the coordinate position, size, rotation angle, etc. of the frame in the frame header information in the page data displayed at that time. , find out which frame the graphic cursor is on when clicked. When the corresponding frame (frame number) is identified through this search process, the process proceeds to step S2, where the user selects whether the rotation angle should be input numerically from the keyboard 8 or input by the operator's sense using the mouse 9. . When inputting the rotation angle using the keyboard 8 is selected, the numerical value is input in step S3, and the process proceeds to step S7. Further, if the mouse 9 is selected as the input target, the process proceeds to step S4, where the relative movement distance and button status are input from the mouse 9, and in step S5, the rotation angle is updated based on the results and the obtained rotation is The display of the outline of the frame of interest is updated based on the angle. Hereinafter, this step S4. The process in S5 is repeated until it is determined that the mouse 9 has been clicked. Then, the updated rotation angle at the time of clicking is determined as the rotation angle of the frame of interest, and the process proceeds to step S7. In any case, once the rotation angle for the designated frame is determined in step S1, the value is stored in the "rotation angle" column provided in the frame header information of the frame of interest in step S7. Then, in step S8, the frame of interest is actually rotated based on the stored rotation angle. The rotation process is as described above, so a detailed explanation will be omitted here. As described above, the frame (and information within the frame) designated by the operator is rotated. One problem here is how to handle information within a frame that has been placed, for example, in the background of the rotated frame due to frame rotation. Now, suppose that two frames 70 and 71 are adjacent to each other as shown in FIG. 7A, and frame 71 is rotated (however, frame 71 has priority over frame 70 (front location)). In this case, CPU 1
The simplest process is to display only the rotated frame 71' and leave the information in the frame 70 untouched, as shown in FIG. However, in this case, the characters located behind the frame 70' cannot be seen. Therefore, in this embodiment, when a frame configured as described above is rotated, if part of the other frame is eclipsed by the process, r character dodge j is performed as shown in FIG. make it possible. In addition, in the same figure (C),
A mark 72 displayed at the lower right of the frame 70° indicates that the character string has overflowed from the frame. This mark 72 is
The frame 70' is resized so that all the characters inside can be displayed, or the display continues until a predetermined number of characters are deleted. By the way, in order to meet the demand that "character avoidance" may not be performed in some cases, the attribute information for each style (see Figure 4) includes information that indicates that the character string within the relevant frame is subject to "character avoidance". (The operator specifies these attributes for each frame, but as an initial value, the frame that expands character strings stores data indicating that characters should be avoided.) ).Of course, the frame in which the image is expanded is not subject to the "text avoidance" process due to the nature of the information. As described above, even if a frame does not overlap with another frame before the frame is rotated, it may overlap after that process. Therefore, it is necessary to determine which frame the image is superimposed on by rotating the frame. In the embodiment, as shown in FIG. 7(B), when the frame is rotated by 71 degrees, the points A at the four corners of the frame. The coordinate positions of B, C, and D are determined, and each point is determined by comparing it with the coordinate position and size (including the rotation angle) in the header information 32 of each frame displayed at that time. For example, in the case of FIG. 7(B), if the size and coordinate information in the header information of the frame 70 are compared, point B is located within the frame 70.
It can be determined that it is inside. Next, the "text avoidance" process in the embodiment will be explained. "Character avoidance" in the embodiment is processed according to the rules shown below. In other words, ``by rotating the frame of the line of interest (if the line is divided into a few spaces where characters can be expanded, expand the character string in the wider expansion width)'' Figure 8 (A) shows the character string expansion. This is a case where there is a frame 82 (a frame in which characters or images are developed) within a frame 81. In the case shown in the figure, the space in which characters can be developed is divided to the right in the 3rd and 4th lines in the frame 81 by the frame 82. However, since it was determined that the space on the left side was wide, the character string was expanded as shown in the figure. Figures 8 (B) and (C) show the results when the frame 82 in Figure 8 (A) is rotated at different angles. This shows the result of the "character avoidance" processing for frame 81. In the same figure (B), the space in which characters can be developed is on the right in the second and third lines, and on the left in lines 4 and 5. This shows that it was judged to be wide.In addition, in the same figure (C),
Each row indicates that the left side is determined to be wide. An overview of the "text avoidance" processing of CPLI 1 will be explained using FIG. 9. Basically, the widest space in which characters can be expanded is found for each line. In the case shown, the first metal body becomes the space where characters can be developed, and in the case of the second line, βL and b are compared and the larger one (
In the illustration, β, l) is a character expandable space. Thereafter, the characters read from the character code area 33 are sequentially developed into the determined space until the space reaches the determined character development space. However, since each character has a character attribute (data in the character attribute area 34), a character pattern is generated and developed based on the attribute. When character expansion in the character expandable space for one line is completed, focus on the next line and repeat the same process.
When the line to be processed finally goes outside the frame of interest, the process ends (°, ° There is no point in processing characters that are not displayed). The above-mentioned processing can be summarized as shown in the flowchart shown in FIG. First, in step Sll, the first row is set as the row of interest as an initial value. In the next step S12, the character code area 33
Then, data for one character is read from the beginning of the character attribute area 34. After this, in step 313, the widest character expandable space in the line of interest is selected. In step S14, the size of the character pattern generated based on the previously read data for one character is compared with the selected character expandable space, and it is determined whether the character pattern can be expanded in that space (step S14). If there is no character expandable space in the line of interest and it cannot be selected in step 313, it is naturally determined that character expansion is not possible). If it is determined that it is the development period, the process proceeds to step S15, in which the character pattern generated in the character development possible space is developed,
In the next step S16, data for the next character is read, and the process returns to step S14. In this way, character patterns are developed one after another until it is determined that the character pattern cannot be developed in the character development space.Now, when it is determined that the character pattern that is about to be developed cannot be developed in the line of interest, the process advances to step S17. , move the line of interest to the next line 6 Then, in step 318, it is determined whether the updated line of interest has moved out of the frame currently being processed. Then, unless it is determined that the line of interest has gone outside the frame, the process returns to step 313 and continues the above-described process. As a result of the above processing, Fig. 7 (C), Fig. 8 (B), (C
) can be obtained. In addition, in the process described above, if it is determined that even one character pattern generated in the line of interest can be expanded, that character is expanded, but in this case, only one character exists in that line. There will be cases where you don't. Therefore, when the process moves from step S12 or step 818 to step S13 (excluding the process from step S16), the selected character expandable space is
Determine whether there are more than the number of characters (or length C). By doing this, it is possible to eliminate the unnaturalness of having only one character on one line.In this case, the variable n (or the length may be changed depending on the operator's preference) Good. <Explanation of the second embodiment> In the embodiment described above, a plurality of objects (one
For each frame rotation, the widest one was selected from among the spaces in which characters can be developed (up to 2 characters). In the example of Mizui 2, we will explain an example of "dodging characters" in a way that is easier for readers to understand. In general, it is easier to understand horizontally written Japanese and English when sentences flow from left to right. Therefore, as shown in FIG. 11(A), when the character developable space is divided into left and right by the rotation process of the frame 112,
Make the characters (sentences) flow as shown in the figure. However, as explained in the first embodiment above, if the number n of characters that can be expanded in a line in each expandable space is less than a predetermined value, characters are not expanded there and the process shown in FIG. Make it flow like this. Switching from FIG. 11(A) to FIG. 11(B) can be easily achieved by increasing the setting value n, so a detailed explanation thereof will be omitted here.As explained above, this implementation According to the example, it is possible to rearrange a sentence that has a character string that is hidden by rotating the frame to avoid the rotated frame. In the example, horizontal writing was explained as an example, but similar Since the principle can be applied to vertical writing, the present invention is not limited to this. [Effects of the Invention] As explained above, according to the present invention, character strings that are hidden by rotating the frame can be reproduced. It becomes possible to provide an extremely convenient document processing device that can be arranged and viewed.
