DETAILED DESCRIPTION [Overview] A graphic processing system that is advanced by an object-oriented system. When displaying and processing a drawing in which basic figures and character information are combined, a figure object that defines the shape of the basic figure, the arrangement, area, and operation of the basic figure, and figure elements and areas for the complex figure are specified. The spatial relationship object, the window object that displays the figure and holds the correspondence information between the displayed figure and the spatial relationship object and the figure object, and the corresponding object of the figure element designated on the screen are identified by the area. A window object is provided to notify those objects of a graphic operation instruction. With this configuration, it is possible to obtain a system in which it is easy to recognize and operate a composite graphic in which graphic elements are related. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic processing system of an object-oriented information processing system, and more particularly to a graphic processing system that facilitates handling of a composite graphic including character information and its graphic operation. [Problems to be Solved by Prior Art and Invention] FIG. 5 is a block diagram showing a configuration example of an information processing system. The processing device 1 executes the program loaded in the memory to exchange information with the input device 2 and the display device 3 of the terminal,
The specified processing is performed according to the command information input from the input device 2. The display device 3 includes, for example, a display device, and the input device 2 includes a keyboard having a function of operating a cursor displayed on the surface of the display device 3. For example, in an information processing system that handles graphics such as so-called CAD (Computer Aided Design) represented by computer-aided design in circuit design, the user touches a key of the input device 2 to input a command or A desired command is input by selecting a menu-type command displayed on the screen with a cursor, and the type, shape, position, etc. of the figure are specified on the display screen of the display device 3, and the command is executed by the processing device 1. The graphic processing system 4 according to the present invention interprets the command, sequentially displays the specified graphic on the screen of the display device 3, and updates the displayed graphic. In this way, the graphics that make up one drawing are generated, but in general, the names, dimensions, explanations, etc. of characters, numbers, symbols, etc. that are represented by graphics on the screen (hereinafter, these are collectively Since it is accompanied by character information), they are also sequentially input and displayed at a designated position on the screen by a key touch or a position designated by a cursor on the screen. The drawing data generally includes two types of data of figures and character information. Among them, the figure data is, for example, straight lines, various polygons, circles, arcs, and other basic figures corresponding to the types of basic figures prepared by the system. Drawings for each figure, consisting of this figure type, the position of the reference point of the figure in the drawing, the specified value of the shape, the line type, the surface fill, etc., and the other character information data is represented by those figure data. Consists of a code string to be superimposed on. The above-mentioned drawing data is simply a set of individual basic figures and data of character information, and a meaning indicating correspondence with an actual object represented by a basic figure or a combination thereof, and such a figure. It is difficult to express the relationship between the character information and the necessary character information. Therefore, it is possible to construct an advanced graphic processing system that can recognize them as a composite graphic and support graphic operation according to the object represented by the graphic. There is a problem that you can not. [Means for Solving the Problems] FIG. 1 is a block diagram showing the configuration of the present invention. The figure shows the configuration of the information processing system. 10 is a figure of a basic figure, data of arrangement and area for each basic figure, or a figure object having a character string including a font in character information and a figure operation procedure, 11 is a complex figure Is a space-related object that defines the structure of FIG. 1 and has data of the area of the composite graphic, and 12 is a window object that displays the graphic and recognizes the correspondence between the displayed graphic and the graphic object and the spatial-related object. [Operation] The interface processing unit 13 generates the specified window object 12 according to the command information from the input device 2, and executes the subsequent graphic operation instruction by the window object 12, thereby specifying the specified graphic object 10 and the spatial relationship object. Generate 11. A graphic corresponding to the generated graphic object 10 is displayed on the display device 3 by the window object 12 as a composite graphic according to the spatial relationship object 11. The window object 12 identifies a displayed basic figure, character information, and an instruction by a cursor or the like for a composite figure by a position related to the area, sends a figure operation designation to the corresponding figure object 10, and the figure object 10 The specified operation determined by is executed, and the result is reflected on the display of the screen of the display device 3. As described above, a graphic processing system in which advanced graphic operations can be easily used by providing various necessary objects in the class objects of the graphic object and the spatial relationship object and preparing the graphic operation procedure and the like corresponding to each of them Can be configured. [Example] An object in an object-oriented information processing system is an information unit of a predetermined format including data, a procedure for processing the data, or both, and the object is often described in a frame format. To briefly explain the general form of the frame structure, a frame column showing the frame name at the beginning, then a slot column showing the type of data etc., a slot column followed by a facet column showing the data type etc., and then a facet column. It consists of the value column. Then, in the case of an object to which the frame format is applied, the object name is used as the frame name, and the value is specified with data, data name, program name, etc.
The meaning and data type of the value described in the Value column are specified by facets. In the object-oriented system, an object that is the prototype of the object description (this is called a class object) is provided for each type of object, and based on the specification from the outside, the class object is the prototype and the necessary data values are specified. The generated instance objects (objects having a relationship of inheriting other information described in the class object, which will be simply referred to as objects hereinafter) are generated, and the processing is executed by those objects. Various objects in the frame format will be described below with reference to the drawings. The interface processing unit 13 in FIG. 1 uses the command information from the input device 2 to select one of the window objects 12
Generate The WINDOW class object of the window object 12 is, for example, a frame having slots as shown in FIG. In FIG. 2 (a), the frame name described in the frame column is "WINDOW", and in the following slots, Nam
By specifying the facet of the e-slot as "class", the window name is described as string data (STRING), and Top and Lef
Specifying an integer value (INTEGER) as the upper left coordinate of the window displayed on the screen by setting the facet of the t slot to “class”, and setting the facet of the Width slot and Height slot to “class” adjusts the respective values. Specify a numeric value (INTEGER) as the width and height of the window, and select Dis
In the played-obj slot, the spatial relational objects 11 of the graphic displayed in the window are designated as a list (OBJECT). Further, in the Access-table slot, an access table (TABLE) as shown in FIG. 2 (b) showing the correspondence between the displayed graphic object and the spatial relation object and the rectangular area covering the graphic on the window is generated. Further, the method slot shows the procedure of the operation used by the window object. For example, in the case of "Access", the position on the screen designated by the user is recognized using the input device 2 and the access-table slot is generated. The object of the graphic or character information is determined by referring to the access table, the menu of the graphic operation procedure of the graphic object is displayed on the screen, and the user selects the necessary operation procedure by key touch or cursor movement. Then, when the required parameters for the selected operation procedure are input, a message including such information is sent to the corresponding graphic object or the like to execute the operation. The LINE class object that designates, for example, a "line" which is a basic figure of the figure object 10 is, for example, a frame having slots as shown in FIG. In Fig. 3, the frame name described in the frame column is "LINE", and the facet of each slot of start point x, start point y, end point x, and end point y is "class". Is specified as an integer value (INTEGER). The Area slot is for inputting the coordinate values of two points at the diagonal positions that indicate the area for identifying the instruction input for this figure (line). As a default value when there is no input, this figure (line) The coordinate values that define the smallest rectangular area that covers the are automatically set when the instance object is created. Also, in the Method slot, this figure (line) is displayed (Disp
lay), erase (Erase), move (Move) and other graphic manipulation procedures. For example, Display is a procedure for expanding a figure at a specified coordinate position in the drawing space, displaying the figure in a required window, and updating the area list of the window object accordingly. Further, in the Window slot, a list of window object names designating the window object 12 displaying the figure is specified. Next, the spatial relationship object 11 becomes a frame as shown in FIGS. 4 (b) and 4 (c) corresponding to a simple map example as shown in FIG. 4 (a). Explaining FIG. 4 (a), two houses are arranged opposite to each other across a road having the name "Yamanote Dori". The first house is specified as a “house figure 0” by a figure object, and two squares (square 0, square 0, in the area indicated by the dashed-dotted line frame (defined by the coordinates of the x mark at the upper left and lower right) are specified.
It is defined by arranging a rectangle 1). The second house is specified by the graphic object as "house graphic 1",
It is defined by arranging three squares (square 0, square 1, square 2) and one straight line (line 0) in the area indicated by the one-dot chain line frame (defined by the coordinates of the x mark in the upper left and lower right). It In addition, the road is the area indicated by the one-dot chain line (the upper left and lower right ×
Two parallel straight lines (line 0, line 1) defined by the coordinates of the mark)
And a composite figure of the character string "Yamanote Dori" (sentence 0) are defined as figure objects. Each of the above figures is specified by each slot of the spatial relationship object given a frame name as shown in FIGS. 4 (b) and (c), and the object specified by the facet and value of each slot is Form spatially related objects hierarchically. An example of the spatial relationship object is FIG. 4 (b) in which the frame name described in the frame column is "graphic map 0". In the figure (b), Class, Subspace, House, Road, Are
a, Position x, Position y, Window, etc. are slots that indicate the attributes of the graphic map 0, and for the "graphic map" in the facet "value", it is a class object that inherits the required information. Specify with "Class",
For "house, road" in the facet "value", it is specified by "Subspace" that it is the type of element figure of the composite figure. Furthermore, in the facet “value”, “house figure 0,
"House 1" has already been specified in "Subspace"
"Road figure 0" in the facet "value"
Is also specified by the “road” that has already been specified by “Subspace”. Then, specify that "WO" in the facet "value" is the window object name list of the window displaying this figure with "Window", and the facet "value 0" is the coordinate indicating the display position in that window. Is specified by Position x "," Position y ", and" A
The rea "slot designates the area of the composite figure with a designated value or the same default value as above. The house figure 0 object, house figure 1 object, and road figure 0 object designated by the above-mentioned figure map 0 object further have a spatial relationship. Although designated as an object, a road figure 0 object is illustrated in Fig. 4 (c), in which the frame name described in the frame column is "road figure 0", The figure 0 object is decomposed into basic figures, where Class, Subspace, Dat
a, Area, Position x, Position y, etc. are slots indicating the attributes of the road figure 0, and the Data slot indicates the list of figure object names (line 0, line 1, sentence 0) of the constituent elements, and Position x, Position The y slot, Area slot, etc. are shown in the same meaning as above. Next, for example, a "line 0" graphic object of the road graphic 0 object is decomposed to the minimum unit of the basic graphic as shown in FIG. 4 (d), so that it is generated as an instance object of the LINE class object. Although not shown, prepare a Method slot if necessary,
Designate the procedure for displaying, erasing, moving, and other graphic operations on this graphic. The sentence 0 graphic object is described, for example, as shown in FIG. 4 (e). The coordinates of the upper left corner of the character string at the starting point x and the starting point y slot, the arrangement direction of the character string at the direction slot, and the character type at the font slot. And the character content is specified in the string slot. Although illustration of the house figure 0 object and house figure 1 object shown in the figure map 0 object is omitted, a spatial relationship object and a figure object decomposed from the spatial relationship object are generated in the same manner as described above. As described above, various necessary objects are provided in the class objects of the graphic object and the spatial relation object, and the graphic operation procedure and the like corresponding to each are prepared for those objects, so that the user can define the meaning corresponding to the real thing. To recognize the complex figure,
It is possible to identify and execute graphic operations as it is,
The advanced graphic processing system can be easily configured and used.
