Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a 7-on-5-tot creation method when registering 7-ont external characters used in microcomputers, word processors, etc.

(Prior art) Figure wK1 (A1. (B) is a diagram showing the display during conventional character registration and the display during normal use, respectively, and shows an example of a pixel configuration in which the IO font pixel matrix is 8 x 5. When registering conventional 7-ont external characters, one font pixel matrix 2 equal to the pixel configuration of the font is displayed on the display device IL such as a CRT, and the font pixel matrix 2 is displayed by pointing with a cursor, light pen, etc.+5 means 3. The desired 7-ont image was created and registered by adding or deleting pixels. However, the pixels for creating the font on the display device 1 were registered so that each pixel of the 7-ont image could be easily pointed at the time of creation. Figure 1 of the IC (A
(see Figure 1 (B)), the balance and shape of the font U when actually displayed or printed (see Figure 1 (B)) are difficult to grasp. In other words, each pixel'f dimension
When you want to delete something, you need to enlarge it to 5mm thick and display it, and when you want to see the whole shape, you need to display it at the normal size, but it has become impossible to satisfy both of these requirements at the same time. In order to eliminate the above-mentioned drawbacks, display on two large and small CRTs 7
Although it has been proposed to use an ont generator, it has the disadvantage of increasing costs because an extra CRT 11 is required.

(Object of the Invention) The object of the present invention is to solve the above-mentioned problems by simultaneously displaying an enlarged 7 font for registering non-standard characters and a 1'□ font for normal display on the same image display device. The font creation method of the present invention aims to provide a font creation method that allows easy font creation. When displaying on a display means in a larger size than in normal use, and creating or deleting one line of drawing work in any pixel on the display means to create a font such as a desired character or pattern, A display in which the pixel size is enlarged compared to the display in normal use and a display in which the pixel size is approximately the same as the pixel size in normal use can be simultaneously displayed on the same display means. V what you did? It is a sign. t.

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

FIG. 2 is a block diagram illustrating one embodiment of an apparatus for implementing the inventive font creation method. By operating the keyboard 1''-11, the 7 font creation mode is selected and supplied to the control computer 3 (hereinafter abbreviated as CPU), and under the control of the display controller 7, the display memory 5 enters the font creation mode. 7-ont pixel matrix image of two large and small !II is generated, and thereafter 0PU13
receives input from the modify key 1 console 12 and controls the programmed modifying operation. The contents of the display memory 15 are as follows:
5 is displayed on the CRT 2 which is a display device.

The screen of the CRT 21 is composed of an enlarged image display frame 22 for creating characters, patterns, etc. within its range, and a full-size image display frame 28 for displaying the characters, etc. being created in their actual size. Each pixel in the enlarged image display 10 frame 22 is enlarged so that it can be easily indicated with the cursor 26. The movement of the cursor 26 is via the correction key 12-1'f on the console 12.
This is done by making 9 works. Each pixel generation/
The operation of displaying the seven onts being corrected during deletion 15 in the same size display frame 28 is performed by executing a program or the like stored in the main memory 14 in the 0PU 18. That is, the cursor 26 in the enlarged image display frame 22
From memory 15 for full display of position A! Detected by the l-dress selector 16, the position σ〉de! - generation, deletion, and simultaneous display in the same size display frame 28 based on the data.

The modification key console 12 includes pixel modification keys 12-2, . Start point 5/end point key 1
2-8, 1-pixel correction key 12-4, end key 12-5, and the above-mentioned cursor control key 12-1. Further, in FIG. 2, 24 and 25 indicate the display state of 7 onts during enlargement and normal size creation, respectively.

Below, the procedure for creating characters/patterns will be explained for each operation. FIG. 8 is a flowchart for explaining the correction of pixels in the invention. First, in order to correct a pixel, the operator operates the cursor 15 cursor control key 12-1 to move the cursor to a location in the enlarged image display frame 22 where the pixel to be corrected exists. When the 1 pixel correction key 12-4 is pressed at that location, the presence or absence of that painting is determined by 0PUI a, and if there is no pixel, a pixel is created, and where there is a pixel, it is deleted and the pixel is reflected. 1 roll. At the same time, the corresponding pixel of 0PU18 Go is the same size image? The image is reversed and the one-stroke correction operation is completed.

FIG. 4 is a 70-chart for explaining the batch correction of multiple pixels in the invention. In the case of batch correction of multiple pixels 5, the operator first presses the cursor control key 12.
-1 to move the cursor to the starting point of the portion to be corrected in the enlarged image display frame 22. When the start point key 12-3 is pressed at that location, the coordinates of that pixel and the corresponding pixel 1P in the same size image are stored as the enlarged image start point and the same size image start point, respectively. Next, by repeating the same operation and pressing the end point key 12-8 at the end point of the portion to be corrected, the enlarged image end point and the same size image end point are stored. Thereafter, by pressing the create or delete key in the pixel modification key 12-2, a straight line from the start point to the end point is created or deleted.ノO Figure 5 shows the simultaneous inversion of multiple pixels in the present invention using
'dH is a flowchart. In the case of batch inversion of multiple pixels, the operator enters the inversion mode by pressing the inversion key in correction keys 1 and 2-2, and the subsequent operations are almost the same as in the case of batch correction described above. . The only difference is that in order to perform inversion, it is necessary to check whether the corresponding pixel in the original image exists or not; in the non-implemented example, after determining the presence or absence of the pixel, the value of the deletion flag is I can tell you that information. Therefore, if there are 10 pixels at the starting point, the pixels from the starting point to the ending point are deleted, and if there are no pixels, they are generated, thereby completing the inversion operation.

If you press the end key 12-5 after completing the creation of the 7-ont by the various operations described above, the 7-ont consisting of the created characters and patterns will be created and the code entered from the keyboard at IEIJ will be displayed. be registered. From now on, you can use the registered font by entering this code from the keyboard.

Non-invention is not limited to the above-mentioned □ Examples211
Many modifications and changes are possible. For example, in the above-mentioned embodiment, the size to be actually used was displayed after creating the same size image, but it is not necessarily necessary that the size is exactly the same as when actually used. It doesn't matter how big the darkness is so that you can get a feel for the entire 7 onts. Furthermore, it is not necessary to always display the enlarged image and the same-size image at the same time; for example, it is also possible to display characters or the like for reference on one side.

(Effects of the Invention) As is clear from the above detailed explanation, according to the uninvented font creation method, both an enlarged image with large pixels and easy to correct, and an approximately life-size image that gives an actual displayed image are Since the font is displayed on one CRT, it is easy to understand the overall shape of the S font and to create individual pixels. Furthermore, since pixels can be inverted and modifications can be made without specifying generation or deletion, the creation time can be shortened. Roughly, it can be executed on one CRT.

(as it can be done, the cost will not be high). l-self
