Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a character pattern generation method, and particularly to a printer,
This invention relates to a character pattern generation method in a terminal device such as a video terminal.

[Conventional technology]

Conventionally, this divine character pattern generation method divides characters into a grid and stores information on whether each part is white or black.

[Problem that the invention seeks to solve]

In the conventional character pattern generation method described above, character pattern information is stored as a dot image, and character resolution is limited by the number of dots into which a character is divided, making it impossible to represent complex characters. Another disadvantage is that when the characters are enlarged, the diagonal lines become step-like and the characters become very unsightly.

Problems to be Solved by the Invention An object of the present invention is to provide a character pattern generation method that improves the above-mentioned drawbacks by generating character patterns in an analog manner.

[Means for solving current issues]

In the character pattern generation method ri of the present invention, which generates a pattern using a vector method, information on parts and circular arcs that constitute the outline of one character pattern, and information on points indicating the inside or outside of the outline are provided. [Embodiment] The following 1 invention is constituted by comprising a + stage for storing the character pattern, and a means for filling out the inside of the outline when generating the character pattern, or inverting the outside after filling out the outside of the outline. The character pattern generation method will be explained with reference to the drawings.

FIG. 1 is a diagram showing the first actual case of the present invention.

In the figure, the character pattern generation system includes a receiving ml that manually receives data from a host device, a receiving buffer 2 that temporarily stores the data, and a decoding unit 3 that discriminates the data.
A character generator 5 that stores character pattern information in advance, an image processing unit 4 that generates a character pattern while searching the character generator 5 according to the above data, an image buffer 6 that temporarily stores the above character pattern, and one character. It has a printing section 7 that reads a pattern from the image buffer 6 and prints it. That is, the figure shows a character pattern generation method in a dot matrix type printer.

FIG. 2 is an enlarged view showing an example of character patterns stored in the image buffer 6 described above. In the same figure, the outline is given by the character pattern ri ligament Ll-LIO and the circular arc CI. Then, a character pattern is generated by filling the inside of the outline with a point P inside the outline.

FIG. 3 is an enlarged view of a character pattern showing a second embodiment of the present invention. In the same figure, character pattern rltm Lt
It is contoured by t~Lt4o and the circular arc CIl~C1m. Then, a character pattern is generated by filling the outside of the outline with the point ptt outside the outline and then inverting it. This can be easily realized by adding a reversal processing function to the same system configuration as in the above character pattern diagram.

FIG. 4 is a diagram showing a third embodiment of the present invention. [In Figure 51, the character pattern generation method is based on the video R that temporarily stores the character pattern generated by the image processing section 4.
AM16 and a display that reads character patterns from the video RAM 16 and displays them? 5u @ section 17 and C1tT18
It is equipped with That is, the figure shows a character pattern generation method in a graphic display. In addition, in the same figure, receiver 3 section l, receiver section 7 a 2. Decoding section 3. Image processing section 4. and character generator 5V''
i It has the same function as in Fig. 1. Furthermore, character patterns can be generated as described in FIGS. 2 or 3.

〔Effect of the invention〕

As explained in detail above, according to the uninvented character pattern generation method, the minutes and arcs that make up the outline of the character pattern are stored as character pattern information, and when the pattern is generated, it is painted using the outline as the boundary. Since the method is flattened, it has the effect of obtaining a high-quality character pattern through simple processing.

Also, since the character pattern information @i is stored as a vector, it has the effect of reducing the storage area compared to the dot-z generation system.

Figure 41 is a block diagram showing the implementation of the letter P/11 of the present invention, Figure 2 is an enlarged view showing /, ;d of the character pattern, and Figure 3 is a block diagram showing the implementation of the present invention. Second Embodiment FIG. 4 is a perspective view showing an example of the character pattern according to FIG. 1, and FIG. 4 is a perspective view showing a third embodiment of the present invention.
