Abstract

PURPOSE:To improve the operability and operation efficiency by automacally displaying all selected elements including a part which exceeds an image plane and is not displayed before the selection at a position and with magnification matching operation within a display limit coordinate range. CONSTITUTION:A calculating means 13 calculates the display limit coordinates of elements on the screen of a display 15. When one element on the screen of the display 15 is selected with a selecting means 16 such as a light pen, an update storage means 14 reads the coordinate values of the selected element out of a 1st storage means 11 and, calculates coordinates for movement display from the display limit coordinates from the calculating means 13, and stores them in a 2nd storage means 12. Then the display 15 makes a display according to the coordinates for the display stored in the 2nd storage means 12, so the selected elements are displayed including the part which exceeds the screen and is not displayed before the selection according to the coordinates for the movement display which are updated and stored into the 2nd storage means 12 so that the selection position or center value of the elements is in the center of the screen.

Description

[Detailed Description of the Invention] [Summary] Regarding the window processing method b by selecting elements on the screen in a computer-aided dissection (CAD) system, the purpose is to improve the operation efficiency of window processing and to select the method. In a window processing method in which an arbitrary element on a screen of a display selected by a means is moved and displayed at a specified position at a desired magnification, a first storage means for storing coordinate values of each selectable element; a second storage means for storing display coordinates indicating the position of the element being displayed on the screen; and a second storage means for storing display coordinates indicating the position of the element being displayed; a calculation means for calculating a display limit coordinate indicating a limit position; and a calculation means for reading out from the first storage means only the coordinate values of the element selected by the notation selection means among the selectable elements and outputting the coordinate value from the calculation means. Calculate moving display coordinates for displaying the entire selected element within the screen, and update and store the moving display coordinates in the second storage means as the display coordinates. The present invention relates to a window processing method, and more particularly, the present invention relates to a window processing method, and particularly to a window processing method by selecting elements on a screen in an H1 machine-aided design (CAD) system. Regarding the processing method. In a CAD system, a window operator is required that selects and enlarges/reduces necessary graphical elements from among the graphical elements projected on the screen of the display, and moves as well. For this reason, it is desired to improve the efficiency of window processing in terms of operation of the CAD system.

[Conventional technology]

Conventional window processing first specifies the enlargement/reduction of graphical elements on the display screen. This designation can be made by inputting from the Yarboard or by placing the light pen on a predetermined position on the screen (for example, when the light pen is placed on an arbitrary position on the 10th half of the screen, it will be enlarged, and when it is placed on an arbitrary position on the 10th half of the screen, it will be enlarged; Togi is reduced).

Next, use the light pen to indicate the part of the graphic element that you want to move to the center of the screen. As a result, all graphical displays on the screen will move, and the part indicated by the light pen will be located in the center of the screen and will be displayed at the initially specified enlargement or reduction ratio.1. [Problem to be Solved by the Invention] However, in order to enlarge/reduce the size of the above-mentioned graphical elements to a magnification suitable for the work, the operator has conventionally performed the enlargement/reduction based on his or her appropriate intuition, and also , some of them are not displayed on the screen but protrude from the screen, so in order to get the graphic elements at the optimal magnification and position for the final work, you need to perform the same window processing many times. The present invention has been made in view of the above issues, and provides a window processing method that can improve the operability and work efficiency of window processing. The purpose is to provide a method.

[Means to solve the problem]

FIG. 1 shows a block diagram of the principle of the present invention. In the same figure, 11
12 is a first storage means, and 12 is a second storage means that stores coordinate values of each selectable element and display coordinates indicating the position of the element being displayed on the display 15. I remember.

Reference numeral 13 denotes a calculation means that calculates display limit coordinates indicating a limit position that can be displayed on the screen based on the display coordinates. 14
is an update storage means, which reads only the coordinate values of the element selected by the selection means 16 from the first storage means 11 and displays the entire selected element on the display screen together with the display limit coordinates from the calculation means 13. The coordinates for display are outputted as the latitude stem, and the external target for moving display is updated and stored in the second storage means 12 as the coordinates for display.

In the present invention, the display 15 selected by the selection means 16
A window processing method for moving and displaying an arbitrary element on a screen at a specified position at a desired magnification, comprising the above-mentioned first storage means 11, second storage means 12, calculation means 13 and update storage means 14. It is something.

[Effect]

Elements (graphical elements such as circles and lines) on the screen of the display 15 are stored in the second storage means 12, and their display limit coordinates are extracted by the calculation means 13.

In this display state, when a certain element on the screen of the display 15 is selected with the selection means 16 such as the light 1 to the pen,
The update storage means 14 reads out the coordinates of the selected element from the first storage means 11, calculates the moving display coordinates based on this and the display limit coordinates from the calculation means 13, and stores the coordinates in the second storage. The means 12 is made to update and store it.

Since the display 15 performs display based on the display coordinates stored in the second storage means 12, the above-mentioned selected element is displayed based on the display coordinates for movement stored in the second storage means 12. Based on this, the entire element, including the part that was not displayed because it was off the screen before selection, is an appropriate size within the display limit coordinate range, and the selection position or the center value of the element is at the center of the screen. 1 [Embodiment] Figure 2 shows a configuration diagram of an embodiment of the present invention. 1 In the same figure,
Components that are the same as those in Figure 1 are designated by the same reference numerals. , In Figure 2, 20 is the central river! The system (CPU) is composed of a processing section 21 and a memory 22, the memory 22 constitutes the first storage means 11, and 23 is a noisle which stores the actual elements such as lines and circles. This is an external storage device that stores the coordinate values of . ．． 2 4+. The second storage means 12 is comprised of a display control section 25 and a screen memory 26. , display control section 25
is connected to the CPU 20 via the interface unit 24, and causes the display 15 to display the figure based on the display coordinates of the figure from the screen memory 26.

27 is a pen, 28 is a keyboard, these are [,
It constitutes the selection means 16 which has not yet been mentioned.

Processing section 21, interno server section 24, and display control section 2
Reference numeral 5 constitutes the calculation means 13 and the update storage means 14, which are realized by the processing section 21 according to the processing steps of the flowcharts 1 to 1 shown in FIG. This will be explained with reference to FIGS. 2 to 4. Upon startup of the CPIJ 20, the storage coordinate information of the file 23 is transferred to the memory 22.

On the other hand, based on instructions from the processing section 21, the display control section 25 reads out the coordinates of the graphic elements stored in the screen memory 26, and displays them on the display 15.

In this state, the processing section 21 operates at step 30 in FIG.
It is judged whether the input of the selected element is on the right side or not.
When the operator performs a selection operation on an arbitrary position on the display tree of the display 15 using the pen 27 or the V-board 28, the processing section 21 determines that the selected C element is to be input.

For example, suppose that the screen of the display 15 is displaying a figure in which a circle and a line segment ■ partially overlap, as shown in Figure 4 (A>), and the position of point O is moved to the center of the screen. Here, the coordinates of the four corners of the screen are (X
+ , Y+ >. (X2 .Y2 >. (X3 .
Y3) and H (Xa.Y4), and the coordinates of one end point of line segment Only the part between (Xs . Ys ) and (X6 . Y6 ) is displayed, and the marked part is overflowing from the screen.The operator holds the light pen 27 as shown in FIG. When the position of point 0 is hit or the position coordinates of point O are input using the keyboard 28, the processing section 21 determines that the selection element has been input in step 30 of FIG. Actual coordinate values of selected elements ■ and ■ <X7
, Yy >, (XB, Ya), etc., the display coordinates (X6 .
Y6) Read out the incense and mark the external mark for display (Xs,
Y6 ) etc. are displayed on the control unit 25 → internoce unit 24
The processing unit 21 calculates the display limit coordinates indicating the limit position where the line segment ■ can be displayed on the screen.Next, the processing unit 21 selects the selected element I. Using both coordinates of II and the display limit coordinates, calculate the coordinates for movement display, transfer these to the screen memory 26 via the interface unit 24 and display control unit 25, and use this as an external target for display. Avoid updating memory.The coordinates for moving and displaying are such that both selection elements 1 n and 1 n are displayed on the screen, and the coordinates of the selection position O are in the middle of the screen. The external target values of both pant points of the line segment ■ are (X7', Y7'), (X8' .
Y8').

Next, at step 3/I in FIG. 3, the changed display coordinates are read out from the screen memory 26 and displayed on the display 15 by the display control section 25. As shown in Figure 4 (1-8), the actual coordinates of the selection summary ■ and H are displayed as ■' and ■' respectively on the screen, including the line segments that are not displayed on the screen before selection. and the coordinates of the selected position O are O'
It is displayed at the center of the screen as if it were small. In this way, according to the present embodiment, by just one operation of selecting an element with the light pen 27 or the gearboard 28, the element is automatically selected at a magnification suitable for the work and so that the specified position is in the center of the screen. You can process the window to display.

Note that regarding the hierarchies, the center of the element {ITj can also be placed in the center of the screen.

〔Effect of the invention〕

As described above, according to the present invention, the selected element is automatically positioned and magnified to suit the work within the display limit coordinate range, including the part that was not displayed because it was off the screen before selection. Because it is now displayed, window processing can be done with just one selection operation.Therefore, there is no need to perform window processing many times as in the past, greatly improving operability and work efficiency. It has the features of
