Description of the Invention (1) The present invention relates to a personal computer (PC) or a handheld personal computer. , HPC) to realize the italic font display method, especially without using an extra memory boat to stagger the preset italic font, you can use the shift operation to convert various fonts and fonts according to the use The angle of italics set by the user is displayed in italics. Since there is no need to occupy too much memory to stagger various different italic fonts, the efficiency of memory usage is improved and the display query speed is accelerated. At present, most conventional PC or HPC devices use a preset font library for display. Generally, in addition to the standard font library, the system will provide some special deformed font libraries to enrich the effect of font display. The most common deformed font is italics. When the system wants to display the italics of certain text or icons, it will search the corresponding font library 'to find the required italic font, and then display it on the glory screen through the display system. The italic font library's way to handle italic font display does have its convenience, because the system can use the existing font library to complete the italic font display. However, in practical applications, the conventional technology has a number of shortcomings in the processing of oblique ship characters. The main shortcoming of the conventional technology is that it must occupy a considerable memory space. In PC applications, various font libraries (including italic font libraries) will be 'uploaded' from the hard disk device to the main memory when the system is loaded, so it will take up space in the main memory; while in HPC applications , Generally recorded in _Read Memory (Read Only Memory, ROM), so it will occupy —JI \ I ---- 衣 · (谙 Please read the precautions on the back before filling this page) Dimensions are applicable to China National Standard Half (CNS) A4 (210X297 mm) 412691 A7-B7 V. Description of the invention (2) — IΓ1- " ϋζ Iyi — I (谙 Please read the precautions on the back before filling this page) Memory space in system ROM. On the other hand, various font libraries are actually represented by a dot matrix, and the amount of data is quite large. Taking Chinese characters as an example, if displayed in a 16x15 font, each Chinese character (or It is a Chinese italic font), which requires 16 × 15 = 24〇 (bits) ', that is, 30 bytes of data. For six thousand commonly used Chinese words, S ′ requires 30x6000 = 180k bytes of memory space. If you consider the different fonts and icons again, this amount of data is quite substantial. Therefore, the biggest disadvantage of the conventional italic display method is that it must occupy a large amount of memory space. '^. Printed by the Consumers ’Cooperative of the Central Bureau of Standards and Commerce of the Ministry of Economic Affairs In addition, because the conventional fonts are used to display italic characters in conventional technology, it also causes problems in the display effect. Β is most obvious because Each font is displayed by a preset italic font. The enemy's adjacent Chinese characters, English characters, and icons cannot overlap. In addition, all italic fonts use a rectangular display range, so The effect of the presentation is not very natural. Especially in the case of large angle tilt of some relatively complex glyphs, this situation is even more obvious. In addition, at present, in most PC and HPC systems, the display of Chinese characters, English characters, or round labels (and italics) must be limited to 8 or multiples of 8, which also reduces the use of Flexibility in application. Therefore, 'if it is possible to display italics without using a font library' can naturally reduce the occupation ratio of the system's memory space, and can also solve the shortcomings of most conventional technologies in the display effect. However, the premise of this new method is that the processing steps must be very simple, so as not to increase the burden on the system display. At the same time, the processing steps must fully comply with the general Chinese national standard (CNS) of standard digital paper sizes. } A7- B7 Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V. Invention Description (3) The data processing mode, so that it can be more easily applied to the field of PC or Hpc. In view of this, the main features of the present invention The purpose is to provide a method for realizing fast display of italics, which can produce the required italic display effect without using italic font library. Therefore, no additional memory space is needed to preserve italic characters. The type library can also achieve the desired display effect. [4] Another object of the present invention is to provide a method for quickly displaying italic characters, which can use a simple number shift operation to achieve the effect of displaying italic characters. Because the italic font effect is implemented using a simple number shift operation, the displayed font is not limited to the range of general fonts, so it can Show more natural italics. At the same time, because the actual operation is quite simple, it will not cause a burden on the system display. According to the above-mentioned object, the present invention provides a shift operation to achieve fast display of italics. The method can be applied to HpC or PC. First, there must be a standard font library in the system to provide the standard font to be processed. Then, according to an italic font angle, read out the corresponding italic font. Angle shift sequence. After the user specifies the string to be processed, the character point matrix of each character in the string is read from the standard font library, and then according to each shift of the shift sequence Bit item, horizontally shift each column of the font dot matrix to generate a set of italic font dot matrix β. Finally, the italic font dot matrix can be directly displayed on the screen.

Description of the invention (5) is a handheld personal computer (HPC ) Model as an example to explain. This is because HPC is limited by volume and generally cannot provide a very large memory space for use. Therefore, the italicized fast display method provided in this embodiment is used to process words. When the display is displayed, the efficiency of using memory space can be significantly improved. In addition, the present invention uses a simple digital processing technology to display italic characters, so the system itself must provide at least a set of standard (non-tilted) characters. The library is used as a reference for processing. The following describes the hardware part of the HPC of this embodiment and the italicized display soft palate part of the present invention, which are described below. Figure 1 shows the hardware block of the HPC in this embodiment. Architecture diagram: As shown in the figure, HPC includes CPU (Central Processing Unit, central processing unit) 10, keyboard 20, external interface card 30, LCD (liquid crystal display) display 40, LCD driver 50, ROM 70, and random access memory (RAM) Memory) 80. CPU 10 is used as the processing center of the HPC to control other components in the HPC and to process various applications. The keyboard 20 is used to provide user input data and give instructions. The external interface card 30 is It is used to expand the data function of HPC. As for ROM 70 and RAM 80, it is used to store fixed data (such as font library, operating system programs, etc.) and temporary data (such as user data) of HPC. When operating the HPC, the required information can be obtained through the LCD display screen 40, and the general LCD display screen 40 is driven and displayed by a dedicated LCD driver 50. In this embodiment, the HPC system itself must provide standard characters Array library, and this font library can be stored in ROM 70. fill .----- i ------ Order ------ 嗖 1 (Please read the precautions on the back before filling in this Page) This paper size applies to China National Standards (CNS > A4 specifications (: 21 × 297 mm) 412691 π ^ __ V. Description of the invention (6) When the CPU 10 performs italic display, the corresponding standard is read from the ROM 70 Font bitmap. After processing, the corresponding italic font bitmap is temporarily stored in the RAM 80, and then displayed through the general display program. • Through the LCD driver 50, the italic font dotmap is displayed on the LCD. Display screen 40. Based on the hardware architecture of the above HPC, the following describes the procedure for actually processing italics. Printed by the Consumers 'Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the notes on the back before filling this page) The' font dot matrix circle to be processed in this example is a 16x15 font, however, the present invention can also be applied to other Type of font, such as 24x24 font. The oblique character display method disclosed in this embodiment is a process of horizontally translating each column (a total of 16 columns) in a standard font bitmap according to a predetermined inclination angle '. Therefore, in the ROM 70 of the system, the number of translation points made by each column when different tilt angles must be stored first. In this embodiment, the data of the translation points of each column under different tilt angles are collectively stored in a shift table. The second circle represents the schematic diagram of the italicized word processing shift table used in this embodiment. As shown in the figure, the shift table contains an array shift sequence, which corresponds to "standard", "30 degrees to the right", "30 degrees to the left", "45 degrees to the right j" and "45 degrees to the left" 》 Each set of shift sequences contains 16 shift items, corresponding to the 16 columns of the font lattice 囷 ”For a shift sequence inclined 30 degrees to the right, (7, 7) represents the font lattice The top two columns of the circle are shifted to the right by 7 points, (6, means the next two columns are shifted to the right by 6 points, and so on. The shift sequence is shifted by 30 degrees to the left In other words, (0, 0) means that the top two of the font lattice 囷 do not move, and (1, 1) means that the next two columns 'shift 1 point to the right', and so on. 45 ° to the right Θ This paper scale is suitable for {CNS) plus one-printed by the Central Bureau of Standards of the Ministry of Economy, printed by the Bayer Consumer Cooperative 412691 Ar _____B7 Five 'Invention Note (7) and 45 ° to the left, then Follow the same procedure. As can be seen from the above, each shift sequence shown in the second circle is processed by shifting each column of the bitmap to the right, so the shift operation becomes very simple. It must also be noted that FIG. 2 only illustrates the case of certain italic characters, but it is not a limitation of the present invention. In the case of other different tilt angles, other corresponding shift sequences can also be selected to achieve. The user can choose the deformation he wants to achieve, and generate the corresponding shift table data according to the "second sequence" method. The present invention does not show the required deformation according to the data provided by the user. In addition, The shift table shown in the figure can be applied to the case of 16x15 fonts. In the case of 24x24 fonts, each shift sequence must contain 24 shift items, corresponding to the 24 of the font's dot matrix circle. According to the shift table shown in Section 2 (a), the following describes the processing flow for achieving fast display of italics in this embodiment, as shown in Figure 3. First, according to the angle of italics set by the user, The corresponding shift sequence is read from the shift table in FIG. 2 (step S1) e, and then the string to be converted is read (step S2). This string can be a single word or several words The composed text string "After reading the string, calculate the length of the string, set it to LEN, and set another processing word variable a (step S3). The initial value of the processing word variable a is 丨, in Handle word variables while processing the entire string A will increase with the word currently being processed. After completing the initial processing described above, the actual italic type conversion will begin. First, from the standard font library, read the standard 9 papers of the A word.

Then read in according to the step M For each column of the standard glyph point matrix that reads a person, a corresponding horizontal translation is performed (step S5. As described above, each shift sequence in this embodiment is translated in the same direction (right shift ). After the translation process is completed, the translated point matrix can be written into the italicized point matrix of the memory (step S6p if A; tLEN (step ^ S7), indicating that the target substring has not been processed yet) Therefore, the processing word variable a is accumulated by 1 (step S8), and processing is returned to step S4. If a = len, it means that the string has been processed, so the italicized dot matrix circle can be based on The normal display program is output to the LCD screen (step S9), and the display of italics is completed. After the processing steps in FIG. 3, the italics font can be displayed on the string specified by the user. Figures 4A to 4E 囷 show the standard fonts, and the diagonal dot matrix of 30 ° to the right, 30 ° to the left, 45 ° to the right, and 45 ° to the left after performing italic processing in this embodiment.

As shown in the figure, the dot matrix of the standard font is 16x15 (Figure 4A), and in the case of a 30-degree oblique right (Figure 4B) and a 30-degree oblique left (Figure 4C), the entire italic font is Amplification is 16x22, and in the case of a 45-degree oblique right (Figure 4D) and a 45-degree oblique left (circle 4E), the entire italic font is expanded to 16x30. In fact, if italicized fonts are processed with two consecutive words, since they are not limited to the range of individual fonts, the dot areas of the fonts can overlap, and the display effect is more natural. Figures 5A and 5B respectively show an example of the conventional technology and the font dot matrix of the present invention in the case of processing continuous font display.

Description of the Invention (9) The italic font is used to display the continuous italic font in the font library as a unit, so it displays a less natural display effect. In addition, in Figure 5B ' In the present invention, italic characters are processed by a shift operation. Therefore, font display is not limited to a rectangular font bitmap, and adjacent fonts are partially overlapped. The display effect is also relatively natural. It can be seen that the italic display method used in the present invention is indeed superior to the conventional technique. The present invention uses a shift operation to quickly display italic fonts, which has the following advantages: 1 * It does not need to occupy the italic font memory space, so the memory usage efficiency of the entire system can be improved. Models with less space, such as HPC, have very significant improvements. 2. The shift calculation process is quite simple, so it does not cause too much load on the system when displaying italic fonts. 3. The display of italic font is more natural, and it is not limited to the preset italic font. Therefore, it can display continuous italic font in the desired position. Although the present invention is disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and retouches without departing from the spirit and scope of the present invention. The scope of protection of the invention shall be determined by the scope of the attached patent application. 11 m scale applicable; National Standard {CNS) A4 specification (2 丨 0X297 mm) (谙 Please read the precautions on the back before filling this page) Clothing-Order
