Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a screen display method for mixed text and graphics, and in particular, to a method for displaying text and graphics on a mixed screen, and in particular to a method for displaying text and graphics in an easy-to-see manner by effectively using the screen. This invention relates to a method for displaying mixed figures on a screen.

<Prior Art> For example, when a design drawing or the like is created interactively in a CAD/CAM system, a message text and a drawing may be displayed simultaneously on the screen of a display device. At this time, as shown in Fig. 5, the message is displayed on the left side of the CR7 screen 1, while the drawing is displayed in the drawing display area 4 set on the right side of the screen, and the message and the drawing are displayed separately. That's what I do.

<Problems to be Solved by the Invention> However, conventionally, the drawing display area 4 of the screen is fixedly set as the display area of the right half of the circle, for example, so that the message is not displayed as shown in FIG. 6(A). When each row of If there are long lines, the message will overlap the drawing and some of the characters and shapes will become unclear.

In view of the drawbacks of the prior art, it is an object of the present invention to provide a mixed screen display method for characters and graphics that balances the display size of character information with the display size of graphics so that both characters and graphics can be easily seen. do.

<Means for Solving the Problems> FIG. 1 is a schematic explanatory diagram of a method for displaying a mixed screen of characters and graphics according to the present invention.

14 is a display screen, and this display screen 14 is divided into a message display area 30 and a drawing display area 32.

Function> A message is displayed with the left end of the message display area 30 of the display screen 14 as the top position of the line, and the display length Q of the longest line in the message is determined. Then, the message display area 30. The size of the drawn figure display area 32 is determined, and the drawn figure is displayed to fill the drawn figure display area 32.

<Embodiment> FIG. 2 is a block diagram of a display device for a CAD/CAM system according to the present invention. In Figure 2,
The display device 10 includes an input/output ink face 12 that receives message data, drawing data, etc. from the outside;
A display 16 having a display screen 14 (FIG. 1) and an R O storing programs for displaying messages, drawings, etc. on the display screen 14.
M2S, a RAM 20 for storing received data and various data necessary for displaying the display screen 14, a frame buffer 22 for storing data to be displayed on the display screen 14 in the form of bit images, and a RAM 20 for storing received data and various data necessary for displaying the display screen 14, a frame buffer 22 for storing data to be displayed on the display screen 14 in the form of bit images, and a RAM 20 for storing received data and various data necessary for displaying the display screen 14, and a frame buffer 22 for storing data to be displayed on the display screen 14 in the form of bit images. A processor 2 that manages various processes necessary for the operation of the display device 10 such as display.
Consists of 4.

CA D/CAM systems are designed to create blueprint data, processing data, etc. in an interactive format. Therefore, during the design process, for example, drawing a drawing based on data that has already been input, and making changes to the next input operation. A message indicating necessary selection conditions is displayed at the same time, and the system main body sequentially forms message data and drawing data according to the operator's operations and outputs them to the display device 10.

The display device 10 displays message data and drawing data input from the system main body on a display screen 14.
Each area 3 is obtained by dividing the display area (range of AXB in FIG. 1) into two: a message display area 30 and a drawing display area 32.
Messages and drawings are displayed separately at 0 and 32.

Hereinafter, a method for displaying a mixed screen of characters and graphics according to the present invention will be described.

Referring to flowchart 1 in FIG.
4 receives message data for displaying the next screen from the system main body side via the input interface 12, and stores it in the RAM 20 (steps 100 and 102).

Next, set N, which represents the length of the longest line of the message, to zero,
The first line of data is read from the message data, and while being converted into a character font corresponding to each character data, it is written to a predetermined line position of the frame buffer 22 and displayed on the screen (steps 104 to 108).

Here, the display screen 14 is divided into two, a message display area 30 on the left side and a drawing display area 32 on the right side, and messages are displayed with the left end of the message display area 30 as the starting position of the line. It will be done.

The processor 24 then displays the display screen 1 in the first row.
4.Register the blue flame above as Q, compare the size of N and Q, and if Q is larger, set N=Q and register the length of the longest line N.
If Q is less than or equal to N, leave N as before and change the second
If there are no lines below the line, move on to the next drawing process (Step 1
10 to 116), if there is a second line, read the data of the second line from the message in the RAM 20, and convert each character data to a character font while displaying the message display area 30.
is written to a predetermined position in the frame buffer 22 corresponding to the second line starting from the left end of the frame buffer 22 and displayed on the screen (steps 106 and 108).

Next, the processor 24 registers the note length of the second line as Q on the display screen 14, and compares it with N to determine Q.
If is large, change the registered value N of the longest line length by setting N=Q, and if it is less than N, leave it as it is (step 11
0-116).

If there are messages from the third line onwards, store the character font in the frame buffer 22 for each line's message in the same way, change N if necessary, and once the processing for one page is completed. Next, the pro sensor 24 receives the drawing data from the system main body side via the input/output interface 12 and stores it in the RAM 20 (step 118.
120).

Then, the processor 24 sets the position and size of the drawn diagram display area 32 to a position at a distance Q on the display screen 14 from the left end of the message display area 30 as a boundary position between the message display area 30 and the drawn diagram display area 32. rear,
RA so that the figure is displayed completely in the drawing display area 32.
The drawing magnification is determined based on the drawing data in M20 (for example, represented by drawing commands, numerical values, etc.), various figures are generated as bit images according to the drawing data, and the frame buffer 22 corresponding to the drawn figure display area 32 is The message is stored in a predetermined location, the figure is read together with the message, and is input into the CRT to be displayed on the screen (steps 122 to 3).
128). Note that frame buffers may be provided for messages and drawn figures, respectively, and the frame buffers may be combined when outputting to a CRT.

Fig. 4 (This is an example of the display in which the present invention is applied; Fig. 4 (A)
(B) shows the case where the maximum message line length is long, and (B) shows the case where the maximum message line length is long.

In the above embodiment, if the length of the longest line in a message becomes too long, the drawing display area 32 becomes relatively too small, so an upper limit is set in advance on the length of the longest line in a message formed by the system main body. It is desirable to keep it. Alternatively, the system main body side does not set a restriction on the length of the longest message line, and the display device side sets a lower limit value in advance for the size of the drawing display area, and when the boundary position exceeds this lower limit, the lower limit value is set in advance. The drawing display area may be set based on the size and a certain degree of overlap with the message display may be allowed.

<Effects of the Invention> As explained above, according to the present invention, the size of the figure display area for displaying figures is not fixed, but the size is automatically changed according to the maximum blue flame of the message, thereby reducing waste. Since the display screen is effectively used to display figures at an appropriate size by eliminating blank spaces, the displayed characters and figures are easy to see.
