TW457439B - High quality character generation device - Google Patents

Abstract

The present invention is a high quality character generation device which can generate the exterior frame of character font with arbitrary size and, in addition, it can make the output quality of some specific small character fonts approach those dot-matrix fonts with the highest quality, but will not increase too much amount of the character data. To achieve this purpose, the present invention provides a character generation device which reduces the amount of data by forming the dot-matrix character font from the original dot-matrix reference data (the original dot-matrix reference data is the character stroke data described by the dot matrix), and by sharing the character stroke code, position information, etc. with the exterior frame character font data. High quality dot-matrix character fonts are then generated from the edited dot-matrix reference data and dot-matrix correction data.

Description

457439 V. Description of the invention (I) Background of the invention As of today, there are many electronic products, such as online thunder book processing skimmers, forced viewing, online computers and computers, etc. 'need to produce electronic paper and electronic documents Processors, etc. are needed; to produce Renda: two-way electric touch, and the small characters displayed on the glory screen need to have a dot matrix, but the electronic products do not have sufficient memory quality. However font. When you store, you need to find out all the ancient domains that need to be installed. The installation type of the characters, the production points, and the production points of the yuan have the highest quality and the highest quality. A trend is the type of the typeface of the material and the type of the input. The characters are too small. Taiding Jia Te may be able to do so, but the previous technology said. $ The most commonly used fonts are two, one size font. 'In the case of large characters, the quality of the outer frame font can be arbitrarily produced) The quality is very poor. The other is that when the dot matrix is a kid (such as 6 4 X 6 4 with a fixed size, and generally small characters, such as fonts, it is generally used only for a type that is fixed to large characters.) The quality is poor. A set of 1 30 0 0 The high-quality outer space of the Yu word ^ memory space; and the 4 8 X 4 8 size dot-preform 'requires at least 1 2 MB of 7 MB memory space; the 3 2 X 32 dot matrix_font is uncompressed before, Requires 3. MB of memory space; 24 × 24 dot matrix ^ font type before uncompressed, requires 1 · 6 MB of memory space. Even if used alone ^ uncompressed 'requires 0.9 method to reduce this a lot The amount of data. The best compression technology before 2 also considers that many electronic goods need to have more;

457433 V. Description of the invention (2) Dot matrix fonts of different sizes. If these fonts need to exist at the same time, it requires up to several MB of memory space to store these font data. This huge amount of data causes this type of electronic goods. Many problems such as the inability to reduce prices and insufficient font supply. To outline the installation of production. Yuanzizixinzi >? | 1. The quality and quality of the d one is high and the quality is guaranteed. The quantity of the material is low. Due to the large amount of reduction, it will not be produced for a lifetime. The original copy of the Yuanming character was issued in 1 and it was mentioned that when the Ming C issued the original copy, the Yuan's text box outlines the external production of the original text.

Refer to Figure 4 for the complete character generation flow chart. First enter the glyph code, character code, and character size (F 1) to be generated, and then determine whether it is a lattice size (F 2) according to the entered character size. The frame character generator generates the original frame font (F 3). The method for the frame character generator to generate the frame font belongs to the existing technology in the character generation device, and will not be described in detail here. If it is a dot matrix, first read the total number of strokes (F4) of the character code, and then process each stroke (F5) one by one. For the format of the character data, please refer to Figure 2. In this example, the character size needs to be 2 4 X 2 4, 3 2 X 3 2 or 48 X 48 to generate dot matrix fonts, and the rest of the character sizes will generate frame fonts.

V. Description of the invention (5) New value = old value X 24/256 New adjusted distance of key points A new index value corresponding to this lattice size of the original lattice data. Add this value to the array reference index displacement value to find out that the size of the array is not too large. The distance between the key point and the stroke is different from the key point and becomes the same. Therefore, the final point matrix is only 2 in this example. There are two values of the 0 dot parameter and the stroke code. In the dot matrix reference index table, find the final index value (H1) of the dot in the first stroke dot matrix correction data. Because the new value calculated by the point is not too large, the same stroke is most likely due to the proportion adjustment. The reference index is not too large for consideration. According to the final index value, the matrix reference only describes the coordinates of the final image, so the dot matrix reference (H2) must be drawn based on the stroke of the specific dot size. The corresponding lattice reference can be found. The shape of this point, the upper left starting point is determined as the coordinate of the first key point after the original point is adjusted plus the error value, and the final displacement value is obtained. Finally, the corresponding dot matrix reference is corrected by this displacement value () {3) . The missing image integration device 'generates this stroked image from the corrected dot matrix data and combines it with the original image (F8).俟 After all strokes are processed, a dot image can be generated. "F The final amount of data in this example is 1. 64MB, as detailed in the following analysis:

In this case, 'the frame character generator of this system will have no effect'. Only the information such as the code and key point position in the frame character data are used, and the rest are used to generate the frame font and do not need to be used here. The outer frame character data can be removed, so the outer frame character data that needs to be used is called the outer frame 70 core data. The data amount of the outer frame character core data is only about 9 00KB, so the final data amount can be reduced to 900 + 312 + 126] {胙 134 (^ (much smaller than the uncompressed 6.2 MB without the need for an outer frame font).
