Description

Detailed Description of the Invention (5) Technical Field of the Invention The present invention relates to an input data processing method in a graphics processing system, and in particular, the application processing unit that performs graphics processing The present invention relates to an input data processing method in a graphic processing system that allows necessary coordinate data or character data to be obtained from any input source without being aware of the input source.

(B) Prior art and problems For example, in a graphic processing system that inputs and processes graphic information such as IC wiring diagrams and architectural design drawings, coordinate data indicating the position of each graphic element is input, and the It is often necessary to also input character data indicating the type of element. Input sources include, for example, a coordinate input device such as a graphic cursor, a tablet, or a light pen, and a character input device such as a keyboard. However, it is not impossible to obtain character data from a coordinate input device; for example, you can obtain character strings by hitting a menu using a so-called menu-only method, or conversely, obtain coordinate data from a character input device or a character string on a menu. It is possible to obtain. Therefore,
It is desirable to be able to input both coordinate data and character data from any input source as needed.

According to the conventional method, an application processing unit such as any application program that processes graphic information must first perform processing with consideration given to the type of device of the input source, which increases the processing load and increases the processing load. , there was a problem that there was no flexibility in changing the input source. Second, for example, whether character data is input using a menu or directly from a keyboard as a string of character codes corresponding to keys pressed is fixed in advance, and the input mode is now fixed. There is a problem that the input operation means is fixed and the operator cannot arbitrarily select the optimum input operation means.

Thirdly, there is a problem in that when the application processing section requires one unit of data, the input operation means cannot be changed during the input.

(Q. Purpose and Structure of the Invention The present invention aims to solve the above problems, and automatically converts information from any input source into coordinate data or character data according to the request of the input request source, and further converts information multiple times into coordinate data or character data. Even for attention-based inputs, we provide a method for handing over only the ultimately required converted data to the human requester, making it possible to reduce the processing burden, make the input source more flexible and general-purpose, and improve operability. Therefore, the input data processing method in the graphic processing system of the present invention is the input data processing method in the graphic processing system that has a coordinate input source and a character input source and inputs and processes coordinate data or character data. a menu conversion unit that converts coordinate values input from the coordinate input source into menu information based on specified information from the application processing unit regarding graphic information;
The coordinate input device includes a text conversion unit that converts input information from the character input source or the menu conversion unit into character string information, and a coordinate conversion unit that converts input information from the text conversion unit into coordinate data. The present invention is characterized in that coordinate data output from the coordinate conversion section or character data output from the text conversion section is supplied to the application processing section for each data unit requested by the application processing section. Embodiments will be described below with reference to the drawings.

The application processing unit 1 realizes functions determined by a so-called application program, for example, FORTR.
For example, set/viewport instruction 2 and attention instruction 3 are prepared as macro instructions related to this embodiment, which consist of a group of machine language instructions compiled from a user's program written in a high-level language such as AN or COBOL. . The set viewport command 2 is a command that instructs to set an arbitrary virtual coordinate system within the screen coordinate system indicating an absolute position on the screen of the graphic fist display 14. The attention command 3 is a command that instructs to process coordinate data, character data input, menu settings, message output, etc. according to the attention procedure stored in advance in the attention procedure file 5. be. As the parameters of the attention command 3, the entrance name of the attention procedure, the address of the coordinate data buffer 6, the address of the character data buffer 7, etc. are given. The application processing unit 1 is
By simply specifying these parameters and issuing the attention command 3, the required input data can be obtained in the coordinate data buffer 6 or the character data buffer 7, as will be explained below.

As will be described later with reference to FIG. 2, the window control unit 4 is activated by the set/viewboard command 2, and generates information that associates the screen coordinates of the graphic Φ display 14 with the virtual coordinates of the window defined by the user. It controls giving the coordinate transformation unit 16 .

The attention control unit 8 is activated by the attention command 3. The procedure fetch unit 9 searches the directory section of the attention procedure file 5 loaded in advance, and sequentially retrieves each of the procedures from the entrance name specified by the attention instruction 3, as described later with reference to FIG. It fetches statements. Each fetched statement is delivered to the procedure analysis unit 10. The procedure analysis unit 10 successively analyzes the statements, processes the assigned statements, and activates the following processing units corresponding to each statement. When the above statement requests the input of coordinate data, the coordinate processing unit 11 performs processing to obtain the requested number of coordinate data from the data normalization unit 15 and set it in the coordinate data buffer 6. It is something. If the above statement requests the input of character data, the character processing unit 12 obtains the requested number of characters of character data from the data normalization unit 15 and performs processing to set it in the character data buffer 7. The menu setting unit 13 executes processing for setting the contents of the menu table 19 that associates menu positions related to coordinates with character strings according to the specifications of the above statements. Various processing units are provided, including one for outputting promotional messages.

The data normalization unit 15 normalizes the input information from the coordinate input source 25 and the character inputs '# and 26 into a data format required by the attention procedure under the control of the attention control unit 8. It is. The coordinate conversion unit 16 converts the screen coordinates input from the coordinate input source 25 into coordinate data of a virtual coordinate system defined by the user based on coordinate conversion information from the window control unit 4. Further, the coordinate conversion unit 16 analyzes the character string related to the coordinate information supplied from the text conversion unit 18 according to the coordinate syntax, and converts it into coordinate data of a virtual coordinate system.

The menu converter 17 converts the input information from the coordinate input source 25 into corresponding menu position information based on the arrangement setting information by the menu setting unit 13, and sends the information to the text converter 18. be. The text converter 18 searches the menu table 19 according to the menu position information from the menu converter 17, and outputs the character string of the menu corresponding to the menu position.

It also obtains a character code from the character input source 26, performs character string analysis, and when in the menu selection mode, refers to the menu table 19 and edits a predetermined amount of character strings.
Output the editing results as a coordinate string or regular character data. The switching unit 23 guides the output data of the text converting unit 18 to the character data buffer 7 when the character processing unit 12 requests input of character data. Further, when the coordinate processing section 11 requests input of coordinate data, the switching section 23 switches the output of the text conversion section 18 to the side C shown in the figure, and guides the output to the coordinate conversion section 16. When the menu selection mode is specified by the menu setting section 13, the switching section 24 switches the input information from the coordinate input source 25 from the illustrated side to the illustrated side, and guides it to the menu conversion section 17. If no menu is selected, the screen coordinate input information is directly led to the coordinate conversion section 16. Coordinate conversion section 1
6. The menu converter 17 and the text converter 18:
Each has stack areas 20 to 22 for temporarily holding and storing input information. These stack areas 20-2
In step 2, information that is being input is stored, and the results of editing in predetermined take units are supplied to each processing section at the next stage.

Examples of the coordinate input source 25 include a tablet 27 and a so-called graphic cursor 28 that controls a cursor on a display screen, and examples of the character input source 26 include a keyboard 29 and the like. However, in the case of the present invention, since the data normalization unit 15 automatically converts the take as described above, it is possible to arbitrarily input both coordinate data and character data from the character input source 26. Similarly, from the input source 25, it is possible to input coordinate data and character data using a menu. In other words, the application processing unit 1 only needs to specify whether coordinate data or character data is required, without being aware of the types of input devices of the coordinate input source 25 and the character input source 26. You can get the information you need without having to worry about it.

Transformation information by the coordinate transformation unit 16 is given, for example, by a set viewport (STVP) command 2 as shown in FIG. In FIG. 2, reference numeral 31 represents the display screen of the graphic display 14. In FIG. The absolute coordinates corresponding to the position of each pixel on the display screen 31 are so-called screen coordinates, for example 4096X31
When the size is 20 dots, the X coordinate is O~4095
, the X coordinate takes a value from 0 to 3119. These coordinates are determined by the physical conditions of the graphic display 14, and it is desirable for the application processing unit 1 to be able to set any coordinate system within the display screen 31 for convenience of calculation or for versatility. It will be done.

The first parameter “■P1” of 5TVP instruction 2 shown in Figure 2
is the coordinate system set by the user (hereinafter referred to as the window)
It gives the identification name of

The virtual coordinates within the window are (VLX.

VLY) and (VUX, VUY) at the upper right corner. Using this window, you can set the coordinate origin to any position and obtain any unit length. (VLX, VLY) and (VUX.

The absolute screen coordinates corresponding to (VUY) are (SL
X, 5LY) and (SUX, 5UY). There is no need to explain the coordinate transformation algorithm performed by the coordinate transformation unit 16 based on this information.

Next, with reference to FIG. 3, the manner of input processing of coordinate data and character data will be described. For example, when inputting drawing information of a circuit diagram using an IC, it is necessary to input the position information of the IC and the identification code of the IC. The application processing unit 1 prepares an attention procedure file 5, a coordinate data buffer 6, and a character data buffer 7, and issues an attention command 3, as shown in FIG. 3, for example. The illustrated attention command 3 in FIG. 3 specifies rATIJ as the entry base for the contents of the attention procedure file 5. Further, the label rcl-IRBUFJ of the character data buffer 7 and the label rPO8BUl;J of the coordinate data buffer 6 specify the addresses of the respective buffers.

Statement S1 of the attention procedure is
This is an instruction to display an input prompt message. By interpreting and executing this statement S1, the attention control section 8 sends the message field 3 on the display screen 31 of the graphic display 14.
2, the character string "IC-POS)" is displayed. The next statement S2 instructs to input one set of coordinate data. At this time, the coordinate system is
The window name rVPIJ is specified. By this statement S2, the coordinate processing section 11 shown in FIG. 1 requests the data normalization section 15 to input coordinate data. The operator sees the prompting message by the statement 81 and enters the coordinate data D+ (
” p y) can be input. This coordinate data D is stored in the coordinate data buffer 6 via the coordinate conversion unit 16.

Statement S3 is the promotion message r of the IC identification name.
This is an instruction to display IC-CODE)J. Furthermore, statement S4 instructs to input 4-digit character data. Statesmen 1-
84, the character processing section 12 is activated, and the character processing section 12 requests the data normalization section 15 to input four-digit character data. Based on this request, four-digit character data is supplied from the text converter 18 and set in the character data buffer 7. Note that, at this time, it is also possible to input by multiple input attentions until the input character string reaches 4 digits, and this is handled within the data normalization unit 15. Through these processes, for example, the display screen 31
I
It becomes possible to input C information.

The menu is displayed on the tablet 27, for example, as shown in FIG.
It is defined by preparing a character sheet 34 on top and giving many-knee information using an attention procedure. The statement hs5 shown in FIG. 4 provides menu arrangement information. In the case of this embodiment, menus are arranged in 4 rows and 4 columns. Statement S6
The menu position (1,1') is the string rMODIF
This indicates that it corresponds to "Y". In statement S7, the menu position (1, 2) is the string rFDLO.
This indicates that it is compatible with ADJ.

Similarly, up to 16 character strings can be associated.

All of this information will be set in the menu table 19 shown in FIG. As a result, when the menu position (1, 1) on the tablet 27 is hit, the character string "rMODIFY" will be input, but this character data will be inputted character by character from the keyboard 29.
Application processing section 1 in the same way as when inputting the character string "IFY"
It will be handed over to.

(g) As described in detail, according to the present invention, it is possible to make the data request source and the data input source independent, for example, in graphic conversation processing. Therefore, the data requester can obtain the desired data by simply specifying the type and amount of data required, without having to be aware of the input device type or input mode, reducing the processing burden. At the same time, it becomes possible to generalize the system without depending on its equipment configuration. Further, for the operator, data can be entered by selecting an appropriate input device, and input can be performed even with multiple attentions, so there is an advantage of good operability. Furthermore, since a system can be constructed by arbitrarily combining various input devices, it is possible to provide an economical graphic processing system depending on the system scale.
