Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device having a graphic creation function.

(Prior Art) Conventionally, nine document creation devices have been developed that have a function of creating not only character strings but also graphics. Such a device stores basic figures (mother turns) such as a square and a circle in advance in a memory, and reads out the basic figure selected by the keymate from the memory and displays it on the display screen. By the way, a desired figure (combined figure)'f: can be created by combining not only basic figures but also basic figures.

FD (70, -
There are devices that have a graphic creation function that stores graphics in a storage device such as a disk, reads them out when necessary, and embeds them in a document.

(Problem to be Solved by the Invention) In a conventional document creation device having a figure creation function, combined figures are stored in a storage device with a name assigned to them, and are retrieved and output from the storage device using this name. It is now possible to do so. However, when recalling the registered combination shape from the storage device, the image of the combination shape cannot be grasped, so when the combination shape is actually embedded in the document, the image differs from the one assumed in advance, and the balance with the document If the situation is bad, you may feel a sense of discomfort.

Furthermore, when a figure is called up and displayed on the display screen for editing, the calling position may not always be appropriate. - The nine figure data embedded in the document are the absolute coordinates (
Since the graphics are managed based on coordinates within the page, deleting, moving, and rereading the graphics requires a lot of effort.

An object of the present invention is to read out a pre-registered combined figure from a storage device and embed it in a document, so that it is not embedded into the document until the operator has determined the desired image. An object of the present invention is to provide a document creation device capable of performing graphic calling processing.

[Structure of the Invention (Means and Effects for Solving Problem 11) The present invention has a function of calling up the cause of death registered in the memory in advance in the graphic mode and displaying it on the display screen, The image creating means is a completely biased device for creating predetermined image data from the graphic data read out by the graphic calling means and displaying it at a position on the display screen specified by the cursor of the input device. The apparatus further includes display means for displaying graphic data determined based on the image data at the position on the display screen where the image data is displayed.

19 The present invention also includes an enlargement/reduction means for enlarging/reducing the graphic data read out by the figure calling means, and predetermined image data is extracted from the graphic data enlarged/reduced by the enlargement/m small means. This device has image creation means for creating an image and displaying it at a position on the display screen specified by the cursor of the input device.

With this configuration, when calling registered graphic data, it is possible to determine and confirm whether the type 1 data to be recalled and its display position are appropriate, based on the image data spread over the graphic data. Become. Furthermore, by enlarging/reducing the image data, it becomes easy to create a figure of an appropriate size.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment.

However, in the professional diagram of Figure 1, functions that are not directly related to non-invention, such as kana-kanji conversion, are not shown. The document creation device of this embodiment uses a key gate input device (key gate: KB) as input means for inputting characters, functions, and instructions.
ll- have. Key? The -do JO is provided with a cursor key and a graphic mode designation key as keys related to the present invention.

Key? - Information input from the code 10 is received by the key manual control section 21 of the CPU ZO. The key human power control section controls the import of key human information into the CPU (such as data transfer requests made by the &-IJ input when the key is -), and also controls the type of information input (character data, cursor movement, etc.). Is it a command such as instructions or starting a function?)
The key human power information is passed under the control of a predetermined program, and the processing of that program is executed. C
The PU 20 has a loaded floppy disk (FD).
) is connected to a floppy disk device (FDD) 30 for sending and receiving data. In this embodiment, an FD storing combination graphic data is loaded into the FDD JO. The CPU reads data from FDD j O and writes data to FDD 30.
The FDD control unit 22 of Zo is in charge. FDD control section 22
FDD 3 to access the specified sector address of the FD.

various commands (SEEK command, REA
D”/■ITE command) and sends and receives data.

Since the FDD control unit 22 is well known, detailed explanation will be omitted. A liquid crystal display (LCD) 40 is connected to the CPU z o for displaying document information, messages to the operator for executing functions, and the like.

The information displayed on the LCD 40 is stored in the display information memory (VR
AM) 50th memorized tail. VRAM 5' 0
has a storage location of 1 bit corresponding to 1 bit displayed on the LCD 40, and is configured as a bitmap memory that can be accessed for each bit. The CPUj17 is provided with a display control unit 23 connected to the LCD 40 and the VRAM 5011C, which reads and writes display information to the VRAM SO and sends data read out from the VRAM 50 to the LCD 40 in accordance with the display timing. Take control. When the CPU 20 writes or reads display information to or from the VRAM, when the dot position coordinates Cx, y on the LCD display screen are given to the display control unit 23, the address of the VRAM 50 corresponding to these position coordinates is accessed. It has become. The display control section 23 is provided with a cursor register 24 . The cursor position coordinates (, Cx *Cy) are stored in the cursor register 24, and the display control unit 23 stores the V corresponding to the cursor position coordinates.
A cursor pattern (in this embodiment, a cross cursor/mother turn that specifies the dot position on the screen of the LCD 40 at the intersection point) is written to the address of the RAM s o, and the
40 screens. When the key input unit 21 detects that a cursor key pointing in any direction is pressed, the coordinate values (Cx, Cy') in the cursor register 24 are updated in the direction indicated by the pressed cursor key.

In this case, the display control unit 23 deletes the original cursor gloss turn from the VRAM 50, and deletes the VRAM corresponding to the new coordinates.
) Write the cursor pattern to the memory location of Al1. Incidentally, writing of the cursor is performed by inverting the pit information currently stored in the VRAM 50 according to the cursor pattern, and erasing is also performed by further inverting the pit information according to the cursor pattern. This is a measure to prevent the original character pattern from being erased even if the cursor pattern overlaps with the character pattern. The CPU 20 is provided with a combination figure processing section 25 that controls the processing of the combination figures of the present invention. The combined figure processing unit 25 includes a “combined figure calling program 25J” and a “figure movement control program 2”.
52", "Graphic enlargement/reduction grogram 253", "Image creation/display program 254", "Graphic data creation program 255", "Graphic data storage grogram 256"
It is made up of. The operation of each program will be explained in detail later. A memory 60 is connected to the CPU 20 as a storage unit for data created or used by the combination graphic processing unit 25.

The memory 60 has a storage section 61 for document data (document character data, document graphic data), and a storage buffer (combined graphic buffer) 62 for combined figures read from the FDD j O.

The operation of this embodiment will be explained below.

When the graphic mode designation key provided on the KBIO is pressed and the key code corresponding to this key is received by the key control unit 21, the 1st combination graphic processing unit 25 is activated, and first the content of graphic processing is selected. A guide will appear at the bottom of the screen. For example, the display shows the keys to be pressed and the contents of the process, such as "insert key → figure creation (recall)", "move key → figure movement", "save call key → figure save", etc.

The operator can execute a desired process by pressing a designated key. Among these functions, the present invention is concerned with the function of "drawing (calling)".

When CPU z o is set to graphics mode, "
When the insert key is pressed, the graphic data creation program 25
5 is activated. First, the graphic type selection screen shown in FIG. 2(a) is displayed. The figures numbered 1 to 7 in the figure are basic figures. By the way, when the ``convert/next candidate key'' provided in KBJO is pressed, other basic figures (circles, sectors, ellipses, etc.) are displayed in the same format along with their numbers. For these basic figures, figure generation routines (for example, one-way generation, circular arc generation) are provided within the system, and a meter (starting point and end point for one-way, folded rock, arrow, etc.), and for a circle, By providing the center and radius for a quadrilateral, the diagonal vertices for a quadrilateral, and the type of line, the coordinates of the dots that make up the figure can be obtained. For example, in the case of generating a "sector" shape, "
Press the Select/Next candidate key to display the line types in order and specify the line type (solid line, dashed line, -dotted chain line, etc.)""Press the Select/Next candidate key to display the line thickness in order and specify the line type." Specify the thickness (1 dot width, multiple r dot width)""Specify the center with the cursor → Execute key""Specify the starting point of the arc with the cursor → Execute key""Enter the angle of the arc → Execute key" Parameters are entered in the step. The position of the first dot on the screen on the document page is always managed, so the coordinates of the starting point of the center coordinate 1 arc within each document page (
The position coordinates with the top of the page as the origin) can be calculated by reading the contents of the cursor register 24 and adding them to the top address of one screen each time the execution key is pressed. Then, the radius can be calculated from the difference between the two coordinates, so the generation formula for a straight line (the algorithm is known) and the coordinates on the line forming the rock and sector connecting the center and starting point or end point of the arc. is calculated, so the dot is inserted into the VRAM SO according to these coordinates (with conversion to a relative address within the display screen based on the in-page position coordinates of the first dot on the screen), Is displayed. The thickness of the line is expressed by interpolating the dots, and the line type is expressed by masking the coordinates when the dots are expanded.

The input parameters (positional coordinates are in the form of intra-page coordinates) are stored in the document graphic data section of the document storage section 61 for each page and managed as part of the document information.

It is also possible to create a graphic such as the one shown in FIG. 3, for example, by combining the creation of the basic graphics described above. At the time of creation, the parameters of each partial basic figure (positional coordinates are in-page positional coordinates) are stored in the document figure data storage section.

When the save call key is pressed in the figure moder, the figure data save program 256 is started, and a guide for specifying the range to be saved and setting the registration code (registered figure name) at the time of saving is sequentially displayed on the LCD 40. go. In other words, save using the following steps: "Start point of the save range At - Specify with the cursor → Execute key""Specify the end point B of the save range (diagonal position from the start point) with the cursor → Execute key""Enter the registered figure name → Execute key" Preparations are made for. The in-page position coordinates of the diagonal corners of the rectangle of the storage range can also be calculated from the in-page position coordinates of the starting point of the screen and the contents of the cursor register 24 at the time the execution key is pressed. Then, the graphic parameters of the page in the document graphic data storage section are searched based on the in-page position coordinates of the points A and B, and the graphic parameters in the storage rectangular area are read out, and each parameter is set at the starting point A1 of the rectangle. Convert to relative coordinate values with the origin (0,0). Each coordinate value in FIG. 2 shows the state after being converted into relative coordinates. The data is then compiled into the data shown in FIG. 3 (referred to as combined figure data), given a figure name ("Christmas" in the example of FIG. 3), and passed to the FDD control unit 22.

The FDD control unit 22 finds a free space on the FD and stores the above-mentioned combined graphic data on the FD. The FD is provided with a storage area for reading the figure data, and the header section contains [Registered figure name 2 First sector address of the area where the combined figure data is stored: The combined figure data is A set of the total number of sectors of the stored area is stored.

Next, a case will be described in which the saved combination graphic data is read out from the FD and used. When the "8→execute key" is input in the state shown in FIG. 2(a).

Input data is passed from the key manual control section 21 to the combination figure processing section 25, and the combination figure calling program 251 is activated. The combination figure calling program 251 first accesses the header section of the FD via the FDD control section 22 and reads out all the registered figure names stored in the header section. Then, the read registered figure name is associated with a number and displayed in the form shown in FIG. 2(b). In this state, the process involves inputting the selection number of the registered figure name. Here, [5, Chris ÷ Sco is the desired combination figure, so [
5->Enter the execution key by the operator. The combination figure calling program 251 is the key human control unit 2
When you receive the data from 1 to [5], you can see that it is a call to a shape registered with the shape name "Christmas", so go to the FD with the registered name "Christmas" and search for the part.
Obtain the first sector address of the area where the corresponding combined figure data is stored and the length (number of sectors) of the area, start the FDD control unit 22, call up the combined figure, and store it in the 1 combined figure buffer 62. . In this state, LCD 4
The display of 0 is in the state shown in FIG. 2(C).

Now, conventionally, before calling, the shape is input using a position cursor to embed the shape, and the called combination shape is converted into the format of in-page position coordinates, stored in the document shape data storage unit, and read out. The display coordinates of the lines constituting this figure are calculated from the figure data, a dot is written to the VRAM 50 (writing C1''), and the
I was called at 20, but it was displayed. In this case, if you are too far from finding the desired shape, the recall position is unbalanced, or the size is not good, start a new shape mode and delete, recall, or move the shape. ,
Processing is complicated because enlargement/reduction processing must be performed. Also, when deleting or moving a figure, the displayed figure must be erased, but only the bits of the called figure remain, leaving the originally displayed document/figure f: V'RAM 20 It is very difficult to delete the graphic data from the document graphic data, and after deleting the graphic data recalled from the document graphic data, it is necessary to recall the document information from the storage unit 61 and display the document again. Furthermore, moving a figure, enlarging/reducing a stone block involves processing such as specifying the target range (rectangle), and converting the figure data (in-page position coordinates) to dead relative position coordinates with the starting point of the rectangle as the origin. It gets even more complicated.

On the other hand, in this embodiment, the combination figure data stored in the combination figure buffer 62 is set as the t-origin at an appropriate position on the current screen (for example, the top P (0°36) of the second line) and a bit image is created. Expand to.

In this state, the retrieved graphic data is undefined data and is a temporary display that is not stored as document graphic data. This display is executed by activating the image creation and display program.The combination graphic data having the registered name "Christmas" stored in the zero combination graphic buffer 62 is in the state shown in FIG. The position coordinates of the figures are sequentially developed from this combined figure data. Since this figure display is a temporary figure display, the thickness and line type data are ignored.
A thin line that can be distinguished from shapes already embedded in the document! (for example, a dotted line), along with a rectangle indicating the range of the figure. Thin lines are used to make it easier to expand to dots and write/erase data into the VRAM 50. Dotted lines are used to indicate shapes that already exist in the document and are called up on top of them. This is to make it easier to distinguish between the figure currently being called and other figures when this is displayed. The image creation display program 254 first reads out the data of the diagonal point (x, y) of the area from the combined figure data stored in the combined figure part 7a 62, and calculates the coordinates of this area on the rectangular line as described above. P
The coordinate data is sequentially generated as the point t - the origin, and this coordinate data is given to the display control unit at intervals of several points because it is a dotted line, and the data at the corresponding bit position of the VRAM 50 is inverted (data output → data invert). → rewrite). The purpose of writing by inversion is to protect the previously stored (displayed) data as described above.Next, the 79 rammeters of each partial basic figure are read from the combination figure buffer 62 and the corresponding A figure generation routine is activated, and the position coordinates of the points on the line that make up the entire figure are generated while skilagging the intervals several points at a time, the coordinates are converted so that the origin becomes the point P, and the coordinates are sent to the display control section 23. Then, the display control unit 23 selects AM 5 corresponding to the coordinates.
The 0 bits are sequentially inverted. Then, the image creation and display program 254 sets the on-screen coordinates of point P in the cursor register, and causes the display control unit 23 to display a cross cursor 4ft at the starting point of the rectangle. LCD at this time
The display state of the 40 screens is as shown in FIG. 2(d). Although omitted in FIG. 2(d), document information (characters and figures) is also displayed on the screen.

In this state, processing is passed to the figure movement control program 252. The graphic movement control program 252 is normally in a state of waiting for a cursor key to be pressed, an execution key, and a cancel key to be pressed. If the graphic image desired by the operator is not obtained, the "cancel key" is pressed. When the graphic movement control program 252 detects depression of the cancel key via the key control section 2J, it performs exactly the same operation as the image generation operation described above, and inverts the corresponding pit position in the VRAM 50 again. This reversal returns the display screen to its original display state. Then, the contents of the combination figure buffer 62 are also cleared, and control is returned to the point in time shown in FIG. 2(b).

On the other hand, when a cursor key is pressed in the state shown in FIG. 2(d), the figure movement control program 252 updates the image creation/display quick cursor register 240 in the direction specified by the key.
Move the cross cursor 41. Before the contents of the cursor register 24 are updated when this cursor movement key is pressed,
The image creation and display program 2541 is activated again, and the bit position data in the VRAM 50 corresponding to the called graphic image is inverted again according to the original cursor position coordinates, thereby erasing the original image. After updating the contents of the cursor register 24, the image creation display program 254
'ft is activated, writes the calling figure image (bit inversion) according to the updated cursor position coordinates, and moves the calling figure. Also, when the cross cursor 41 comes to the edge of the screen, the in-page position coordinates of the display top position are updated in units of one line and -digit, and the document information (characters and figures) in the display range is updated from the in-page position coordinates to the document information. The screen is also scrolled by reading it out from the storage area 61, expanding it into dots, and writing it into the VRAM 50. The calling image is generated as the cursor moves, as described above, with the origin of the generation set to the position coordinates stored in the register 24.

Image creation and display program 2 performs the same operation as deployment to
This is achieved by executing 54. Incidentally, if the cursor key is pressed continuously after the cursor key is pressed for the first time, a key repeat code r is added and the key code is received by the key manual control section 2J.

You can also make the shape with a rectangle move faithfully as the cursor moves (although it is impossible to develop all the images because there is not enough time to develop it), but as long as the key repeat code is not received, the shape will move. Since there is little need for image development, the calling graphic image may be generated and displayed only after the key is released and the key repeat code no longer comes. The moving state of this calling graphic image is shown in FIG. 2(e).

When the figure movement control program receives a notification from the key control unit 21 that the execution key has been pressed, it assumes that the type and position of the called combination figure has been determined and performs the following operations. The current cursor position coordinates stored in the cursor register 24 (am with the origin at the top position of the screen C11ii: the same as the top position coordinates of the calling solid area) and the in-page position S (page (coordinates with the beginning of the origin as the origin)
By adding the X and Y coordinates of both 1 and 1, the in-page i mark of the top position of the graphic area is calculated. Based on the calculated coordinate values, all coordinate values for generating a combination figure stored in the combination figure buffer in the data format shown in FIG. 4 are converted into in-page position coordinates. At this time, the terminal sitting image B of the figure area
The values of (X, Y) are ignored, and only the converted combination graphic data (parameters for graphic generation) are stored in the document information storage unit 610 in the document graphic data storage unit corresponding to the page. Along with this operation, the image creation display grogram 254
is activated, reads out all figure generation i4 parameters (including information on line type and line thickness) except data for rectangular display of the figure area from the combination figure buffer 62, and configures each figure t-. The coordinates of a figure are generated using a module that generates the coordinates of a point on a line (including a mask for coordinate generation according to the line type and interpolation of coordinates according to the thickness of the line). These coordinates are converted into coordinates on the screen based on the current cursor position coordinates stored in the cursor register 24, and are passed to the display control section 23. Then, data 11'' is written to the corresponding bit position of VRAM 50.This time, V
When data is written to the RAM 5o, since the figure is fixed, regular data writing is performed instead of the above-mentioned bit inversion writing. As a result, as shown in FIG. 2(f), a regular combined figure is displayed (the line type and line thickness are also specified, and no frame is displayed). When the above operations are completed, the contents of the combined figures P and F 62 are cleared.

With the above operations, a series of combination figure calling operations is completed.
The operation of the CPU 20 returns to the initial state of waiting for a graphic call input. If the "cancel key" is input here, the operation of the combination graphic processing unit ends, and the operation of the CPU 20 shifts from the graphic mode to the normal key manual input wait (document creation mode).

Furthermore, in this embodiment, the processing state of FIG. 2(d) or (6) (the state before the calling combination figure is determined)
You can now enlarge or reduce shapes. In this state, the figure movement control grogram 252
is in a state of waiting for the input of the cursor, and in this state of waiting for manual input, it is determined whether or not there is an input of a key (enlargement/reduction key) assigned to enlarge/reduce the figure.

When the figure movement control program 252 receives the key code of the enlargement/reduction key from the key manual system # section 21, it starts the figure enlargement/reduction program 253. #First, the figure enlargement/reduction program 253 is currently stored in the cursor register 24. Coordinate values (coordinates on the top screen of the rectangular area of the figure (C)C
1, Cyl ) ) in internal RAM (not shown). Then, the message ``Enlargement/reduction?'' is displayed, and the mode shifts to a mode for specifying the magnification using the cursor 41.

In this embodiment, the magnification is specified for a rectangular area of the figure (point A in FIG. 3).

The size of the rectangle (with point B as the diagonal vertex) is specified by changing the size of the rectangle to be similar. That is, the length of the side of this rectangle in the X direction is specified with the cursor 41. When the cursor 41 is moved, the contents of the cursor reno star 24 are updated, but when the operator notifies that the 1 magnification has been determined by pressing the "execute key", the graphic enlargement/reduction program 253 is activated by pressing the "execute key". After receiving the code, the contents of the current Kanle register (Fig. 5. Coordinates of point Q on the screen (C
x2, Cyl)) is read out, and the already stored X coordinate of point A is subtracted from the X coordinate of point Q to find the side length α11t of a new rectangular area. Next, the figure enlargement/reduction grogram 253 reads out the end point BOX coordinates of the rectangular area from the combination figure buffer 62 as the current side length 11 of the rectangular area, and calculates the specified magnification α by calculating α11/l 1 . Next, the figure enlargement/reduction program 253 starts the image creation/display program 254 and uses the parameters (excluding the thickness and m types of information) currently stored in the combination figure buffer 62 to
The dot information of the recalled temporary display figure stored in the RAM 50 is erased (the pit inversion erase described above). Next, the figure enlargement/reduction grogram 253 performs rounding and combining to perform similarity transformation of figures, and rounds off all the coordinates and radius equal length parameters stored in the figure buffer 62 to 6 times the decimal point. quantize), and rewrite the contents of the combination figure P and F 62. Then, the image creation/display program 254 is activated again, and the temporary display 111W of the figure is scaled based on the changed parameters.
(displayed at point W4). Last remembered A
Point *t on the screen is set in the cursor register 24 to return the cursor 41 to the beginning of the entire display rectangular area. By the above-described operation, the figure can be enlarged or reduced before the calling combination solid is determined.

Note that the combined figure data after scaling is similarly stored in the combined figure buffer 62, so the above-mentioned movement,
It is clear that it can be subject to further scaling.

Note that the graphic data to be called may not be stored in the FD, but may be stored in a memo U (ROM, etc.) inside the main body.

[Effects of the Invention] As explained above, according to the present invention, in order to manage and display the retrieved graphic data in an undefined state, it is possible to check the image of the graphic, its position, and its relationship with the document by looking at the display screen. You can freely embed call shapes into a document while checking the balance.

In addition, since the figure is enlarged or reduced on the screen in an undetermined state, the optimum image can be selected with a simple operation without the need for extra processing such as manipulating the pattern data.
