Description of the invention () Field of the invention: The present invention relates to a font scaling method, in particular to a dot matrix font scaling method, and a dot matrix. The font scaling device can be used in various processing systems to reduce the use of hardware resources and improve the efficiency when displaying fonts of various sizes. Background of the Invention: In the application of various processing systems, such as different application software, window systems, or various circular environments, the function of displaying various text fonts and symbols is required to use Chinese, English, or other language texts, to convey system information, achieve communication and communication with users, and complete various functions and operations of the system. Under current common application programs and window systems, the fonts that are more commonly used can include raster fonts, vector font sizes, and true type fonts. Dot-matrix fonts directly use graphic data, that is, the distribution of display points (or lit points) displayed in a certain area to form a shape that represents a specific character or symbol, such as the so-called 16x16 characters Type or 24x24 font, that is, the length and width of each area is 16 or 24 points, using the display of each point in the area to describe the glyph; the vector font provides the end points of the line segments that make up the glyph The collection uses vectors to display the patterns of various texts through operations; while in the true words, it is described by the line segments and curves that make up the outline of the glyph, plus the function of decoration (please read the first Note: Joe filled out this paper. 5) This paper size is applicable to Chinese National Standard (CNS) A4 (210X297 gong). Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 408 275275 A7 B7_ 5. Description of the invention () The shape of the text or symbols. According to the comparison of the above three fonts, the glyphs of the dot matrix font have a fixed size, such as 16x 丨 6 points or 24x24 points. Therefore, the amount of data required for each of the characters is small, and the font file that stores the characters It is small, and the code for font processing is relatively simple. As for the display process, the required calculation process is simplified, the display processing speed is fast, and the required software and hardware resources are very small. However, because the dot matrix font uses a fixed number of display points to represent the text, it is not suitable for reduction or enlargement. Otherwise, it is easy to distort the reduced or enlarged glyphs and affect the font display and discrimination effect. As a result, the font size of the application is subject to many restrictions. In the case of vector fonts and true-to-true fonts, since the font itself does not have a fixed dot matrix size, it can be more unlimited in reducing and enlarging, and it can still maintain the original glyph after scaling, which can fully Meet your app ’s needs for fonts of all sizes. However, the vector font Chengquan font database file is much larger than the bitmap font data file, and often takes several MB (million bytes) to hundreds of MB of storage space. The font processing code is also more complicated, and the processing system resources are limited. Under the circumstances, the processing speed during display will be slower, so the host speed, and hardware and software resource requirements will be much higher than the applications using dot matrix fonts. The various font forms described above can be used in various language families. Text display, as well as basic graphic and symbol display applications, and for applications such as Chinese characters such as hieroglyphics, due to its complex glyphs and character variations, the paper size applies the Chinese national standard (CNS > Α4 ^ Grid < 210 × 297 Gong) --1 -1 I---11-. 丨 ^ -I -_____ 1 — »___ _ _ -5 V- (Please read the notes on the back first and fill in the ΐτ version (Page)-_ Yin Ju 408275 _ ^ __ of the Central Bureau of Standards, Ministry of Economic Affairs and Consumer Cooperatives. 5. Description of the invention () There are many types of characters, and the character set is huge. Take the use in a window environment as an example. Suitable for individuals Brain and higher-level processing systems, and for processing systems with limited resources, such as most portable processing systems or processing systems of personal digital assistants (PD A), Only the dot-matrix fonts of Chinese characters with lower requirements for software and hardware resources are more suitable. Based on the current application of processing systems such as personal digital assistants, 16x16 Chinese dot matrix fonts are mostly used on Chinese fonts. The method of scaling and processing the dot matrix fonts is very limited. The Chinese fonts that can be displayed and output are limited to 16xI6 (that is, characters). The width and height of the dot matrix are 16 dots each), a few bytes such as 24x24, and 32x32 are aligned to eight bits. Not only cannot display dot Chinese characters below 16x16, but also less like 1 5x 1 3, 2 1 x25 And other non-eight-aligned Chinese character fonts, so in processing system applications such as personal digital assistants, the change in the size of Chinese character fonts on its output or display interface is greatly restricted, and cannot be viewed by the user or by different applications. Need to freely adjust the size of the displayed font. Object and Summary of the Invention The object of the present invention is to provide a method and a device for font scaling. Another object of the present invention is to provide a dot matrix font scaling method and a dot matrix font scaling device, which can be applied to various processing systems to reduce the use of hardware resources.

Various instructions and information required when the system is operating; in the case of a personal digital assistant system, the wheel-in unit 20 may be a touch-sensitive induction wheel-in element, or other types of keyboards or buttons. Outside the input unit 20 The font scaling device may include the creation of a font database 22 to record the font data created by the user through the application. Similarly, the creation of the font database 22 may also use random access memory (RAM) ) 'For example, commonly used dynamic random access memory (DRAM), etc. In this example, a scalable font storage device 16 can be integrated to create a font database 22, and the random access memory of the shared system is shared. Physical resources. In the font scaling method of the present invention, the schematic flow chart is shown in the third circle. First, the dot matrix data of the font is read in step 30, that is, the required font is taken out from the font dot matrix database; and then in step Read the font display setting data in the device environment in 32, that is, the size of the font the user wants to display, for example, the original dot matrix font is 16x16, and the user sets the font display setting in the device environment to 18x24; then in step 34, that is, according to the font dot matrix data (16x16) and font display setting data (18x24), calculate the horizontal zoom ratio (= 18/1 6) and vertical zoom ratio (= 24Π 6) β, then proceed to step 36. The horizontal and vertical scaling of the font. The horizontal and vertical scaling of the font in this example is based on the line segments composed of adjacent display points in the dot matrix font. The importance of each point in the dot matrix is different. The points that are displayed (or lighted up) are more important than the points that are not displayed (or not touched). t; Α4 regulations (210X297), (please read the precautions on the back before filling this page) 丨 install * 1T-408275 in V. Description of the invention () Bright points) is more important, so the dot matrix is reduced The minimum length of the display line segment is one, that is, a point, and it will not become 0 due to reduction. The display point in ¾.¾¾ disappears during the zooming process. In the dispute of this embodiment, the dot matrix is enlarged. In order to maintain uniform thickness strokes, appropriate adjustments should be made after the line is enlarged. When the magnification dot matrix is less than 32x32 and the magnification is claw, one of the calculation methods that can be used in this example is: The length of the subsequent line segment = (the original line segment length -1) * m + 1; In addition, if the enlarged line segment length is greater than (the original line raft length * m), then: ---------- crack- ** (Please read the note on the back first!?-^ ¾¾This page} The Central Bureau of Standards of the Ministry of Economic Affairs prints an enlarged line segment for the Industrial and Consumer Cooperatives = the original line segment m ~ i. In order to maintain uniform thickness and strokes, However, when the general font is not enlarged, the stroke may be broken. Therefore, it must be modified. Processing β Therefore, in step 38, the font is modified after scaling, and the modification process is to add display 1 to the break between adjacent display points of the font to target the stroke characteristics of the Chinese font or its hieroglyph. Micro, to maintain the complete continuity of strokes and the positional connection between the strokes. ”After the retouching step of the scaled font in step 38, you can further add step 40 of the class control to rotate the data of the scaled font to Display β in the device environment. In a preferred embodiment, the scale of the paper modified by the body after scaling in step 骅 38 is applicable to the country's national standard (CNS) A4 specification (210X297) 犮 Λ 7 Β7 40827 ^ 5 2. Description of the invention () process, you can check the wide dot matrix to imagine the adjacent state of each display point and its composed line segments and other points in the eight directions of the weekly group, in order to maintain the original stroke connection state and stroke continuity as far as possible. Under the rules, determine the display conditions of certain points on the scaled dot matrix 'to avoid the font from being cut off during the scaling process and the corners of the stroke' and to prevent the pen from breaking In the modification process t, when the display point (ie, the lighted point) is checked for the adjacency relationship, 'in fact, only one side, such as the left or right side adjacency relationship needs to be checked' to determine whether repair is needed and additional display points are needed. Way to keep the readability of strokes. Refer to the third ffl 'It is the detailed font modification of the scaled font in step 38, an example of an embodiment of the detailed process flow diagram' The scaled font modified Buma may include the following steps, first in step 38a 'on the font dot matrix data Take a display point as the reference point, assuming that its coordinates are (X, y); and in step 38b, the font corresponds to the reference point position after scaling, and a correspondence is obtained by scaling according to (x, y). Point [X, Y]; Then in step 38c, first determine the connection relationship between the displayed points in the original dot matrix and the lower left. When the point below the reference point (X, y-1) is not displayed, and the reference point is When the lower left point (3 {_1, Can 1) is displayed, the lower left point γ · 1] of the corresponding point [X, γ] is displayed in step 38d. 'Then go to step Zae 38e, determine the connection relationship between the display point in the original dot matrix character and the upper left, when the upper point (x, y + 1) of the reference point (X, y) is not displayed, and the upper left of the reference point When the point (xi, y + i) is displayed, the upper left point [xi, y + i] of the corresponding point [χ, γ] is displayed at step 38f. Therefore, with the use of Bu Hung 38c to 12 paper sizes, China® House Standard (CNS) Λ4 (210x297 mm) (please read the precautions on the back before filling this page) Printed by the Bureau of Standards for Consumer Cooperation 408S75 A7 B7 Printed by the Consumers Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention () Step 3 8 f, you can judge the connection relationship to the left of each display point of the original dot font , Use the display point to the left of the corresponding point of the font after zooming to achieve the purpose of decoration. Finally, repeat the above steps 'until the modification corresponding to all the display points is completed, that is, using step 38g in the figure, where a judgment is made as to whether the reference point is the last processed display point', and it is possible to repeatedly target each original point. The dot matrix character indicates the purpose of the judgment processing. Refer to the third figure, which is an example of the improvement of the display effect of the font after the scaling method is applied in the present invention. Figure 42 shows the "wen" character of the original 16x16 Chinese dot matrix font; Figure 44 shows This is an 18x24 font with dot matrix characters only directly scaled. It can be seen that the font is damaged due to broken strokes; and Figure No. 46 is an 18x24 font processed using the reduction method in the present invention. It can be seen that the continuity of the font strokes has been significantly improved, and the display effect of the scaled font, especially when zoomed at non-integer times, is avoided due to the broken strokes. Therefore, with the method and device in the present invention, dot matrix fonts such as Chinese characters or other hieroglyphs, characters or symbols can still maintain a good connection relationship after scaling, and display more complete glyphs, and Because the resource is a font library and control data of dot matrix fonts, it can reduce the load of system resources and the demand for system resources during operation, improve the efficiency and effect when displaying various fonts of different sizes, and control the various differences of dot matrix fonts.
