Background of the invention
目前已經有很多的字型產生系統，可用於產生亞洲文 字的字型，亞洲字型係指一些表意圖形所組成的文字字 型，亞洲語言可能包含上千個以上的文字，例如中國語言 就包含二萬個以上的文字。At present, there are many font generation systems that can be used to generate Asian fonts. Asian fonts are text fonts composed of ideographic graphics. Asian languages may contain more than a thousand characters. For example, the Chinese language contains More than 20,000 words.
一種傳統的電腦技術用來產生亞洲字型的方法，係採 用字型的外圍邊線來表現文字的形狀，例如（阿斗米系統 公司（Adobe System, Inc.)描述於n PostScript Language Tutorial and Cookbook” (Addi sion-Wesley Publ ishing，1985)的系統就屬於這種技術，其方法係將 文字字型之外圍邊線儲存成直線段及曲線段的集合，這種 技術有如下缺點：（1)由於不同的字型必須定義不同的外 圍形狀，於是需要相對大量的儲存空間，（2)字型外圍形 狀在高解像度空間上所定義的字型資料，僅適用於高解像 度空間上的顯像，並不適用於在相對低解像度空間上做高 品質的顯像用，換言之，字型資料在不同顯像度空間具有 不能相容的特性。A method used by traditional computer technology to generate Asian fonts, which uses the outer edges of the font to represent the shape of the text, such as (described by Adobe System, Inc. in PostScript Language Tutorial and Cookbook "( Addision-Wesley Publ ishing (1985) belongs to this technology. Its method is to store the peripheral edges of the text font as a set of straight and curved segments. This technique has the following disadvantages: (1) due to different Fonts must define different peripheral shapes, so a relatively large amount of storage space is required. (2) Font data defined by font peripheral shapes in high-resolution space is only suitable for development in high-resolution space, and is not applicable. It is used for high-quality imaging in a relatively low resolution space. In other words, font data has incompatible properties in different resolution spaces.

為了克服外圍字型的缺點，本發明人曾經提出採用圖 樣為基礎的字型產生方法並提出專利申請（美國專利申請 案號09/425, 449，申請日期為公元一九九九年十月二十二 曰），在該案中，一個圖樣是指構成亞細亞文字之個別封 閉形狀的單元，而每個亞細亞文字包含一個或多個圖樣， 且每個圖樣是由一個或多個筆晝所組成，在圖樣基礎之字 型裏，每個文字字型是用各別不同組成之基本圖樣來表 現。圖樣基礎字型具有低容量記憶空間以及可在高解像及 低解像空間具有相容之顯像特質，因此圖樣字型非常適合 於不同解像度系統之間供作字型傳訊使用。 因此，在字型傳訊的應用上就可採用圖樣字型適合字 型傳訊的優點，其需求就是要有一套系統，方法，以及電 腦可讀取的媒介裝置，可提供自動轉換文件被擷取之任何 外圍字型成為一圖樣字型，使得該文件可以在不同解像度 之系統裝置間自由傳遞高品質的字型，不致於產生從高解 像度系統裝置傳遞字型資料至低解像度系統裝置時會產生 品質變差之現象，反之亦然。In order to overcome the shortcomings of peripheral fonts, the inventor has proposed to use a pattern-based font generation method and filed a patent application (U.S. Patent Application No. 09/425, 449, the application date is October 2, 1999. (12th), in this case, a pattern refers to the individual closed-shaped units that make up the Asian script, and each Asian script contains one or more patterns, and each pattern is composed of one or more pens In the pattern-based glyph, each text glyph is represented by a basic pattern with a different composition. The pattern basic font has low-capacity memory space and compatible development characteristics in high-resolution and low-resolution spaces. Therefore, the pattern font is very suitable for font communication between different resolution systems. Therefore, in the application of font messaging, the advantages of graphic fonts suitable for font messaging can be adopted. The requirement is to have a system, method, and computer-readable media device that can automatically convert documents to be retrieved. Any peripheral font becomes a pattern font, so that the document can freely transfer high-quality fonts between system devices of different resolutions, and will not produce quality when transferring font data from high-resolution system devices to low-resolution system devices The phenomenon of deterioration and vice versa.

科奸突貝 的圖樣字型資料。據本發明所轉換出來之圖樣字型資料僅 需相對少之記憶量，適合於在不同解像度之各個不同系統 之間作字型傳訊的應用，不管在高解像度或低解像度之不 同系統的輸出儀上顯像時皆可獲致高品質的顯像字型。 本發明的方法首先定義一組基本圖樣集，然後再用它 們來定義文字的字型集，使得被定義的這些字型適合於在 低或高解像度之輸出裝置上顯像。定義一組基本圖樣集的 方法是從一組文字集中挑選相似形狀的圖樣，然後對每一 被挑選的圖樣逐一定義，每個基本圖樣的定義方式皆一 樣，首先在基本圖樣的外圍邊線定義特徵點，然後再根據 這些被定義的特徵點來定義關鍵點及寬度值。通常，關鍵 點是選在邊緣端點上，或者是形狀彎曲部分的内側或外 侧，或者是主幹中心線通過其他關鍵點之水平或垂直線的 交點上，關鍵點是基本圖樣的第一項外顯參數，其優點是 可藉著移動關鍵點的位置來改變圖樣之外圍形狀。另外， 寬度值也是在基本圖樣之定義裡被採用為另一項的外顯參 數，也具有可藉著改變寬度值來改變圖樣之外圍形狀的優 點。本方法於是再根據這些關鍵點及寬度值反推計算特徵 點位置的方程式，以及再根據特徵點推算曲線形狀之細分 結構裡各個節點上的曲線比例值。曲線比例值乃係根據不 同解像度來分層儲存，使得藉著對不同層級的資料擷取， 可在二個相鄰特徵點間產生不同解像度需求之曲線段，愈 高解像度需求包含愈細密層級的資料，反之，愈低解像度Pattern font information of Kelu Tube. The pattern font data converted according to the present invention only needs a relatively small amount of memory, and is suitable for applications in which fonts are communicated between different systems of different resolutions, regardless of the output instrument of different systems with high or low resolution. You can get high-quality development fonts when developing. The method of the present invention first defines a set of basic patterns, and then uses them to define a font set of text, so that the defined fonts are suitable for displaying on a low or high resolution output device. The method of defining a set of basic patterns is to select similarly shaped patterns from a set of text sets, and then define each selected pattern one by one. Each basic pattern is defined in the same way. First, define features on the outer edges of the basic pattern. Points, and then define keypoints and width values based on these defined feature points. In general, the key points are selected at the edge endpoints, either inside or outside of the curved part of the shape, or at the intersection of the horizontal or vertical line of the trunk center line through other key points. The key points are outside the first item of the basic pattern Display parameters have the advantage that the shape of the periphery of the pattern can be changed by moving the positions of key points. In addition, the width value is also adopted as another explicit parameter in the definition of the basic pattern. It also has the advantage of changing the outer shape of the pattern by changing the width value. The method then inversely calculates the equations for calculating the position of the feature points based on these key points and width values, and then calculates the curve proportion values at each node in the subdivision structure of the curve shape based on the feature points. The curve ratio value is stored in layers according to different resolutions, so that through the acquisition of data at different levels, curve segments with different resolution requirements can be generated between two adjacent feature points. The higher the resolution requirement, the finer the level Data, conversely, the lower the resolution
第11頁 恕^?7 n ' :_ &)L· i 僅需低層級之曲線比例值的資料，本方法藉此機制來產生 與解像度無關之高品質曲線段。本方法反覆使用上述步驟 來定義基本圖樣，使得在文字集的一些相似圖樣，至少皆 能有一個基本圖樣相互對應。Page 11 ^^ 7 n ': _ &) L · i only needs the data of the curve scale value of the lower level, this method uses this mechanism to generate high-quality curve segments that have nothing to do with the resolution. This method repeatedly uses the above steps to define basic patterns, so that at least one basic pattern in the text set can correspond to each other.
根據本發明的一項觀點，本方法在確定每個圖樣外圍 之特徵點的步驟係採自動偵測的程序，該程序先將圖樣固 定在一個極大極小的方框裡，然後確定最左、最右、最 上、最下的切線點為特徵點，決定該些特徵點之後再偵測 其他特徵點的存在，若該些特徵點相鄰之間的曲線段不是 落在相鄰特徵點之連線的同侧，則表示至少有一反曲點的 特徵點需被確定，如果曲線段是在同側則偵查該曲線段上 是否有尖角點的存在可被確定為特徵點，當上述這些特徵 點被決定之後再確定是否該些新的各組相鄰特徵點間之極 大極小方框皆已包含期間之曲線段，若尚未能包含其間曲 線段，則在該曲線段上最左、最右、最上、最下的切線點 處確定特徵點。According to an aspect of the present invention, the step of determining the feature points on the periphery of each pattern of the method adopts a procedure of automatic detection. This procedure first fixes the pattern in a large and small box, and then determines the leftmost, most The right, top, and bottom tangent points are feature points. After determining these feature points, the existence of other feature points is detected. If the curve segments between the feature points are not connected by adjacent feature points, On the same side, it means that at least one characteristic point of the inflection point needs to be determined. If the curve segment is on the same side, it is detected whether there is a sharp corner point on the curve segment. It can be determined as the characteristic point. After the decision is made, it is determined whether the new minimum groups of adjacent feature points have included the period curve segments. If the interval curve segments have not been included, then the curve segment is the leftmost and rightmost. The feature points are determined at the upper, lower, and tangent points.
根據本發明的另一項觀點，基本圖樣係被切割成至少 包含一個單跑段掃瞄線區域，一個單跑段掃瞄線區域係指 在基本圖樣裡的一個沒有空洞的實體部分，該實體部分可 被單跑段掃瞄線填滿，將基本圖樣儲存成單跑段掃瞄線區 域之數據結構的優點，乃是可藉此結構來簡化基本圖樣的 塗黑動作。According to another aspect of the present invention, the basic pattern is cut to include at least one single-run scanning line area. A single-run scanning line area refers to a solid part without holes in the basic pattern. The entity Part of it can be filled by the scanning line of the single run, and the basic pattern can be saved as the data structure of the scanning line area of the single run. The advantage is that the structure can be used to simplify the blacking of the basic pattern.

根據本發明的又一項觀點，用以定義基本圖樣之關鍵 點可以被標示來固定其點矩陣網點區隔上的特定位置，利 用這種標示當作暗示情報，可以微調基本圖樣的細部形 狀，使得字型在低解像度空間上顯像時可避免字型組成圖 樣間推擠在一起的情況發生。According to another aspect of the present invention, the key points used to define the basic pattern can be marked to fix a specific position on the dot matrix dot segment of the dot. Using this marking as hinting information, the detailed shape of the basic pattern can be fine-tuned. When the fonts are displayed on the low-resolution space, the situation that the font composition patterns are pushed together can be avoided.
根據本發明再一項觀點，本發明更進一步地提供一種 方法以及電腦可讀取之媒介裝置具有電腦可執行之指令， 採用一組預先被儲存於基本圖樣資料庫之預先被定義之基 本圖樣集的參數資料，來進行自動轉換外圍字型資料成為 以該些參數定義之圖樣字型資料。如上所述，每個基本圖 樣是被定義成為可產生圖樣形狀輸出的一個程式，其過程 是基於每個基本圖樣是由其外圍形狀上的特徵點為其形狀 輸出的指紋，根據該指紋所確定之特徵點位置，利用預製 預存之劇本句子的解譯來推算關鍵點及寬度值。所以字型 資料之自動轉換的方法係首先去擷取外圍字型的形狀資 料，從擷取字型中逐一以其組合圖樣與該外圍字型的形狀 比對進行將外圍字型資料自動轉換成基本圖樣之參數資 料，首先從外圍字型資料中逐一找出其構成圖樣之特徵點 及其指紋的數據結構，其次從基本圖樣資料庫找尋可匹配 該圖樣指紋之基本圖樣，再根據定義該基本圖樣之參數的 劇本句子解譯如何以特徵點來推算出該圖樣之關鍵點及寬 度值，並將推算出之關鍵點及寬度值儲存於預製之程式According to yet another aspect of the present invention, the present invention further provides a method and a computer-readable medium device having computer-executable instructions using a set of pre-defined basic pattern sets stored in a basic pattern database in advance. Parameter data to automatically convert peripheral font data into pattern font data defined by those parameters. As mentioned above, each basic pattern is defined as a program that can produce a pattern shape output. The process is based on the fingerprint that each basic pattern outputs from its feature points on its peripheral shape for its shape. For the feature point position, the interpretation of pre-stored script sentences is used to estimate the key points and width values. Therefore, the method of automatic conversion of font data is to first extract the shape data of the peripheral fonts, and then automatically convert the peripheral font data to the shape of the combined font and the shape of the peripheral fonts one by one. The basic pattern parameter data, first find out the feature points and fingerprint data structure of the pattern one by one from the peripheral font data, then find the basic pattern that can match the fingerprint of the pattern from the basic pattern database, and then define the basic pattern according to the definition The script sentence interpretation of the pattern parameters explains how to use the feature points to calculate the key points and width values of the pattern, and store the calculated key points and width values in the pre-made program.
第13頁 裡，可藉由該程式之執行來提供該圖樣形狀的輸出，此時 就已經將對應該圖樣之外圍字型資料部分轉換成重新定義 之基本圖樣參數值的圖樣字型資料，反覆上述步驟一直到 該字型資料已經完全轉換成圖樣字型資料為止。 根據本發明之其中一項觀點，當從基本圖樣資料庫搜 尋其中之一基本圖樣來匹配字型資料的圖樣，係指該基本 圖樣之指紋和該字型資料之圖樣形狀的指紋在拓樸結構上 是完全一致的。 根據本發明之又再一項觀點，從事顯像輸出基本圖樣 的程式包含有可從基本圖樣的關鍵點及寬度值決定特徵點 之方程式，該程式更進一步地包含可從每組相鄰兩特徵點 間預製預存於曲線層級表中之曲線比例值來產生該兩特徵 點間的曲線形狀，當該程式在建造某一被選圖樣之顯像 時，該程式包含比對預製預存於基本圖樣之曲線比例值來 匹配該被選圖樣之拓樸形狀。 根據本發明尚且另一項觀點，每個基本圖樣之顯像程 式更進一步地包含一塗黑演算法從事填滿至少一個單跑段 掃瞄線區域，當建造被選圖樣之顯像時，該程式更進一步 地包含擷取其所對應基本圖樣之預製預存塗黑演算法的步 驟0On page 13, the output of the pattern shape can be provided by the execution of the program. At this time, the part of the external font data corresponding to the pattern has been converted into the pattern font data of the redefined basic pattern parameter values. The above steps are continued until the font data has been completely converted into pattern font data. According to one aspect of the present invention, when one of the basic patterns is searched from the basic pattern database to match the pattern of the font data, it means that the fingerprint of the basic pattern and the fingerprint of the shape of the font data are in a topological structure. It is exactly the same. According to yet another aspect of the present invention, a program for developing a basic pattern for development includes an equation for determining feature points from a key point and a width value of the basic pattern. The program further includes two adjacent features from each group. Pre-points are pre-stored in the curve ratio value in the curve level table to generate the curve shape between the two characteristic points. When the program is building an image of a selected pattern, the program contains a comparison of pre-stored pre-stored in the basic pattern. Curve scale value to match the topology of the selected pattern. According to yet another aspect of the present invention, the imaging program for each basic pattern further includes a blacking algorithm to fill at least one single-run scanning line area. When constructing the imaging of the selected pattern, the The program further includes the step of capturing a pre-stored pre-stored blackout algorithm of the corresponding basic pattern.

Note that patterns 3 2, 44, 52, and 66 (the parts shown in white) all have the same shape and structure. , They are a pattern composed of a slightly curved oblique stroke 3 2 a and a vertical pen day 32b. These four patterns 32, 44, 52, and 66 can be defined by the same basic pattern, for example, using pattern 32 Define as the basis, and make the other three patterns from the fine-tuning of the basic pattern. According to the above example, one characteristic of Asian languages is that a limited number of similar patterns are commonly owned by a group of character sets, and the similar patterns have the same shape and structure, as shown in Figures 3 (1) ~ (4). Therefore, if each text can be defined by patterns, and similar patterns can be generated separately from a basic pattern, the amount of font data can be significantly reduced. And the parameter value of each basic pattern can be interpreted by a program to generate the shape and display of these basic patterns. In short, the program explains some calculation processes according to the parameter values. It contains the The outer shape, and the inner area that contains an algorithm to fill the base pattern. Some steps for defining the basic pattern will be described in detail in Figure 4 (1). The next step, as shown in block 24, involves automatically converting the peripheral font data into the pattern basic font data using the pre-defined basic pattern set shown in block 22. Specifically, the text data of each peripheral font is Redefining the text data of "one or more basic patterns" This kind of automatic conversion steps will be described in more detail in Figure 4 (2).

首先參照方塊70，字型設計人員可用掃瞄的文字圖形 檔，或用筆晝基礎的文字圖形檔，當作一組欲被建造成圖 樣基礎的字型集，當然其他方式取得的字模也可以，只要 其影像或者外圍形狀可以被拿來用作圖形的匹配即可。一 組文字集係指相同的字型為主，如果此文字集為中文字， 則不同中文字型的例子有：手寫字體、草體、流體、宋 體、明體等等。字體設計人員可以掃瞄這些文字集，或者 可以使用筆晝基礎之字型集，筆畫基礎字型的定義方法是 描述在美國專利申請案號：08/717, 712 (申請日期：九月 二十日，一九九六年）以及美國專利申請案號： 5, 852, 488，該兩案皆是與本發明相同的讓渡人，簡而言 之，這個方法採用關鍵點及寬度值為其外顯資料，以及採 用特徵點及一個樹狀結構的曲線比例值當作隱含數據。外First refer to block 70. The font designer can use the scanned text graphics file or the pen-based text graphics file as a set of fonts to be built into the pattern. Of course, the fonts obtained in other ways can also be used. , As long as its image or peripheral shape can be used for matching graphics. A group of character sets refers to the same font type. If the character set is Chinese characters, examples of different Chinese character types are: handwritten font, cursive, fluid, Song, Ming, and so on. Type designers can scan these text sets, or they can use the pen-day-based glyph set. The definition of stroke-based glyphs is described in US Patent Application No. 08/717, 712 (application date: September 20 Japan, 1996) and US Patent Application No .: 5, 852, 488, both of which are the same assignees of the present invention.

顯及隱含數據也將被用來定義在本發明上，所以從現有的 筆畫基礎文字集取得的資料，將更容易被用來定義本發明 的方法，因為我們可以直接利用其中部分相同的外顯及隱 含參數的資料。 當一組文字如方塊70所示被掃瞄進來或產生出來後， 則如方塊72所示，字型設計人員開始確認一組相似的圖樣 形狀，確定相似圖樣可藉由觀察一組被掃瞄進來的文字集 中去擷取，或者透過影像分析的技巧去自動擷取。 其次如方塊74所示，字型設計人員從相似圖樣中選擇 < 其中一個圖樣，當作具有代表性的圖樣，並據以用來定義 ^個基本圖樣’這個基本圖樣最能代表這些相似圖形的產 生，通常最常出現的圖樣被選為最具代表性的圖樣，這種 * 選取的步驟可以透過人工篩選或自動取得。例如在方塊72 所示圖三（1)〜（4)的文字中確定相似圖樣32，44，52 · 以及66，然後選圖樣32為基本圖樣來代表那些在方塊74的 圖樣，同理，可以選圖樣64為基本圖樣來代表相似圖樣42 及6 4的這些圖樣，其次如方塊7 6所示，那個在方塊圖7 4被 選擇的基本圖樣就被指定為第i個基本圖樣，本方法定義 | 第i個基本圖樣的數學表現是如下： G^FiUKj}，{Wm}，L)，i=l，.........，n (整數） ♦ G=基本圖樣的形狀 i =基本圖樣的編號Explicit and implicit data will also be used to define the present invention, so the data obtained from the existing stroke basic text set will be more easily used to define the method of the present invention, because we can directly use some of the same foreign Data for explicit and implicit parameters. When a group of text is scanned in or generated as shown in box 70, then as shown in box 72, the font designer starts to confirm a group of similar pattern shapes, and determines that similar patterns can be scanned by observing a group Retrieve the incoming text set, or use image analysis techniques to automatically retrieve it. Secondly, as shown in block 74, the font designer selects one of the similar patterns as a representative pattern and uses it to define ^ basic patterns. This basic pattern can best represent these similar patterns. The most commonly occurring patterns are selected as the most representative patterns. This * selection step can be obtained manually or automatically. For example, determine the similar patterns 32, 44, 52, and 66 in the text in Figures 3 (1) to (4) shown in block 72, and then select pattern 32 as the basic pattern to represent those patterns in block 74. Similarly, you can Select pattern 64 as the basic pattern to represent these patterns of similar patterns 42 and 64. Secondly, as shown in block 76, the basic pattern selected in block diagram 74 is designated as the i-th basic pattern.

(圖一（2 ))裡來執行，該程式包含一組確認特徵點的 規則，如圖四（3 )方塊150所示，基本圖樣的圖形座標是 被設定在一個極小方框理，例如在圖六（1 )的一個圖樣 151是用一個極小方框152來逼近，其次在圖四（3)的方 塊153，本方法於最左、最下、最右、及最上之極小方框 的邊緣上確認四個主要特徵點，在圖六（1 )的四個主要 特徵點Pi〜p4就是這樣被確定的。 其次如方塊154所示，對於每一組相鄰的主要特徵 點，本方法再決定是否其間的曲線段皆在它們連線的同一 邊，參考方塊15 6，例如在圖六（1 )，我們可以看出在兩 個曲線段157a及157b並不位於連接點匕到匕線段的同一 邊，這時必須如方塊158所示，確定轉折點為特徵點，例 如在圖六（1 )的特徵點S4就是一個轉折點。 再如方塊156所示，如果所有曲線段都已經在兩個相 鄰特徵點連線的同一邊，或者已經如方塊158所示，所有 轉折點都已確認，則如方塊160所示，再決定它們之間是 否還有其他尖角點的存在，如圖六（1 )的$就是一個尖角 點，因此如方塊162所示，$就被選為是一個特徵點，最 後，在圖六（1 )的情形就會得到六個特徵點： (Pp $，P2, S4, P3，P4) 如方塊1 60所示，如果已經知道沒有任何尖角點存(Figure 1 (2)), the program contains a set of rules for identifying feature points, as shown in box 150 of Figure 4 (3). The graphic coordinates of the basic pattern are set in a minimal frame, such as in A pattern 151 in FIG. 6 (1) is approximated by a small box 152, followed by box 153 in FIG. 4 (3). The method is applied to the edges of the leftmost, bottom, right, and uppermost small boxes. The four main feature points are identified above, and the four main feature points Pi ~ p4 in Figure 6 (1) are thus determined. Secondly, as shown in block 154, for each set of adjacent main feature points, the method then determines whether the curve segments in between are on the same side where they are connected. Refer to block 15 6. For example, in Figure 6 (1), we It can be seen that the two curve segments 157a and 157b are not located on the same side of the connection point dagger to the dagger line segment. At this time, as shown in block 158, the turning point must be determined as the characteristic point. For example, the characteristic point S4 in FIG. 6 (1) is A turning point. As shown in block 156, if all curve segments are already on the same side where two adjacent feature points are connected, or if all the turning points have been confirmed as shown in block 158, then as shown in block 160, then determine them. Is there any other sharp point between them? As shown in Figure 6 (1), $ is a sharp point, so as shown in block 162, $ is selected as a feature point. Finally, in Figure 6 (1 ) Will get six feature points: (Pp $, P2, S4, P3, P4) As shown in box 1 60, if you already know that there are no sharp corner points stored
第22頁 在，€ 角點已被確定，則再如方塊163所示，做出以 兩個相鄰特徵點為對角端點的方框，再如方塊164所示，Page 22 Now, if the corner point has been determined, then as shown in block 163, make a box with two adjacent feature points as diagonal endpoints, and then as shown in block 164.
察看是否有任何其間的曲線段超出了此方框，果真有的 話，則如方塊166所示，擴展方框來完全包容所有的曲線 段，並確定此新擴展方框的最左、最下、最右、及最上邊 線可能相切的點為特徵點，如圖六（1 )的例子，方框 168a係由兩個相鄰特徵點S4以及Ρ3所組成，這時有部分曲線 段超出了方框168a，因此需要擴展方框168a至新的方框 168b，才可完全包容所有在此兩個特徵點間的曲線段，所 以就在其上確定了特徵點$，它係在方框168的最左邊線 上，其他特徵點S和33亦是透過相同的程序被確定出來 的。 方塊170是個可有可無的步驟，該步驟將在基本圖樣 外圍邊線上示出所有被確定的特徵點，如方塊172所示， 這時，字型設計人員就可觀察其正確性，如前所述，圖樣 的特徵點應當被定義在其外型有曲率變化處，如果有特徵 點沒有被適當地定義，則如方塊174所示，字型設計人員 可直接補增該特徵點。Check to see if there are any curve segments beyond this box. If so, expand the box as shown in box 166 to fully contain all the curve segments, and determine the left and bottom of the new extended box. The points that may be tangent to the rightmost, rightmost, and uppermost edges are the feature points. As shown in the example of Figure 6 (1), box 168a is composed of two adjacent feature points S4 and P3. At this time, some curve segments exceed the square. Box 168a, so you need to expand Box 168a to a new Box 168b to fully encompass all the curve segments between these two feature points, so the feature point $ is determined on it, which is in the box 168 On the far left line, other characteristic points S and 33 are also determined through the same procedure. Block 170 is an optional step. This step will show all identified feature points on the peripheral edge of the basic pattern, as shown in block 172. At this time, the font designer can observe its correctness, as previously described. It is stated that the feature points of the pattern should be defined where the shape has curvature changes. If any feature points are not properly defined, as shown in block 174, the font designer can directly add the feature points.
一旦在圖樣外框中的所有特徵點皆被適當地確認後， 就如方塊176所示，沿著外框的順序儲存所有被確定的特 徵點，例如在圖六（1 )中，本方法可能從h開始追跡，沿 著圖樣外框逆時針方向逐一儲存特徵點直至P4為止。這Once all the feature points in the outer frame of the pattern are properly identified, as shown in block 176, all identified feature points are stored in the order of the outer frame. For example, in Figure 6 (1), this method may Start tracking from h and store the feature points one by one counterclockwise along the outer frame of the pattern until P4. This

時，在相鄰特徵點Pi和^之間就形成曲線段11 ;在相鄰特 徵點Si和82之間就形成曲線段12 ;其餘曲線段亦是這樣形 成的，當然連接任何一個圖樣外框的特徵點可依順時針或 逆時針方向來排列，圖六（3 )係以樹狀結構示出在圖六 (2)中的特徵點，這種樹狀結構的排列順序就構成該基 本圖樣外形的『圖樣指紋』，任何一個基本圖樣表示的所 有相似圖樣，皆和其對應的基本圖樣具有相同的圖樣指 紋，換言之，圖樣指紋確定基本圖樣及其所代表之相似圖 樣的外形。In this case, a curve segment 11 is formed between the adjacent feature points Pi and ^; a curve segment 12 is formed between the adjacent feature points Si and 82; the rest of the curve segments are also formed in this way, of course, connecting any frame of the pattern The feature points of can be arranged in a clockwise or counterclockwise direction. Figure 6 (3) shows the feature points in Figure 6 (2) as a tree structure. The arrangement order of this tree structure constitutes the basic pattern. The "pattern fingerprint" of the shape. All similar patterns represented by any one basic pattern have the same pattern fingerprint as the corresponding basic pattern. In other words, the pattern fingerprint determines the appearance of the basic pattern and the similar pattern it represents.
如圖四（1 )方塊79所示，每個基本圖樣之圖樣指紋 係被儲存起來，並提供進一步地定義基本圖樣使用。As shown in block 79 of Figure Four (1), the pattern fingerprint of each basic pattern is stored and provides further definition of basic pattern use.
其次如方塊8 0所示，本方法定義一些曲線比例值，用 以造出相鄰特徵點間的曲線段，曲線比例值的結構表示了 相鄰特徵點間的曲線段是如何在不同層級解像度的空間裡 被建造出來的。在本發明的具體化表現中，係採用貝茲曲 線產生的演算法來表現曲線段，以及採用曲線層級表格對 照不同顯像度之曲線比例值的列表來分辨曲線段的細密程 度。 圖七（1 )示出一個二次貝茲曲線的幾何，二次貝茲 曲線的產生，可由兩個特徵點h *F2及一個可移動之中間 控制點h所構成的三角形來表現，移動中間控制點込可以Secondly, as shown in block 80, this method defines some curve ratio values to create curve segments between adjacent feature points. The structure of the curve ratio values indicates how the curve segments between adjacent feature points are resolved at different levels. Built out of space. In the embodiment of the present invention, the algorithm generated by the Bezier curve is used to represent the curve segments, and the curve level table is used to distinguish the fineness of the curve segments using a list of curve ratio values for different visualizations. Figure 7 (1) shows the geometry of a quadratic Bezier curve. The generation of a quadratic Bezier curve can be represented by a triangle formed by two characteristic points h * F2 and a movable intermediate control point h. Control point

If the end points of Pi and 1 ^ are connected to form the L2 line segment, and the midpoint of L2 is A, then the quadratic Bezier curve is a tangent to Pi Fi and Pi Fi + 1 respectively. And Fi + 1 and a quadratic curve through A. Here a curve segment can be represented by C (r), where nr ”represents a specific curve proportion value, which is defined as follows: C (r) 二 (Cr (X ), Cr (y) where (^ (xXJxj / LJx) and
Cr(y )二 LJyVLi (y) 因此，再參照圖七（3 )，那麼圖七（1 )所示的曲線 段就被定義為(；（1)，係屬於在特徵點巧和Fi+1間之第0層級 解像度（L=0)的第一條曲線，其值於是被儲存在對應一個 樹狀結構之曲線層級列表的第π Οπ層級裡。 當第一條曲線段需要再細分，以求得更精細的逼近曲 線形狀，可在高解像度輸出裝置上取得更高品質的顯像 時，那就如圖七（2 )所示，將它再細分成二條線段，每 條曲線段也是用貝茲曲線來定義。如圖七（2 )的情形， 在Fi+i，Α以及可移動之中間控制點Ρ2所形成三角形裡，產 生一條被細分的二次貝茲曲線段，同理，此曲線段會和 Ρ2Α以及P2Fi+1*別相切，而且會通過P2*AFi+1線段終點的連 線終點B，這條曲線段就被定義為(；（2)，A和匕間的曲線段 被定義為Cr(3)，這二條曲線段Cr(2)和Cr(3)就被儲存在解Cr (y) two LJyVLi (y) Therefore, referring to Fig. 7 (3), the curve segment shown in Fig. 7 (1) is defined as (; (1), which belongs to the feature point Qiao and Fi + 1 The first curve of the 0th level resolution (L = 0) is then stored in the π Οππ level of the curve level list corresponding to a tree structure. When the first curve segment needs to be subdivided, When obtaining a more detailed approximation curve shape, when a higher-quality image can be obtained on a high-resolution output device, as shown in Figure 7 (2), it is subdivided into two line segments, and each curve segment is also used. Bezier curve is defined. As shown in Fig. 7 (2), in the triangle formed by Fi + i, Α and the movable middle control point P2, a subdivided quadratic Bezier curve segment is generated. Similarly, this The curve segment will be tangent to P2A and P2Fi + 1 *, and will pass the end point B of the end of the P2 * AFi + 1 line segment. This curve segment is defined as (; (2), the curve between A and D The segment is defined as Cr (3), and the two curve segments Cr (2) and Cr (3) are stored in the solution
第25頁 顆 _ 像度層級為n l’’的列表裡，如圖七（3 )所示，曲線段 Cr(2)可能在被細分成二條曲線段Cr(4)和Cr(5)，Cr(4)和 CF(5)就被儲存在解像度層級為Π2Π的列表裡，因此，如圖 七（3 )所示，每條曲線段都會和其所屬解像度層級（L = 0, 1，2)發生關連。In the list of _ image level n l '' on page 25, as shown in Figure VII (3), the curve segment Cr (2) may be subdivided into two curve segments Cr (4) and Cr (5). Cr (4) and CF (5) are stored in a list with a resolution level of Π2Π. Therefore, as shown in Figure 7 (3), each curve segment will be associated with its resolution level (L = 0, 1, 2 ) Related.
藉著對不同解像度層級來定義曲線段的方式，使得本 發明在不必特別在意低或高解像度之輸出裝置的情況下， 皆能得到高品質的字型輸出。字型設計人員可以在兩個相 鄰特徵點間，細分成很多曲線段來定義該兩點間曲線段的 形成，愈細密的曲線段組織愈能提供高解像度的顯像用， 反之，愈上層組織的曲線段愈適合用來提供低解像度的顯 像。例如，參看圖七（3 )的情形，若解像度層級數L 是最上層），則僅是Cr(l)的曲線段會被擷取，若L 是ΠΓ’（中間層），則Cr(2)和Cr(3)的曲線段會被擷取，若 L是Π2Π(最下層），則不同被細分的Cr(3)和Cr(4)以及Cr(5) 的曲線段會被擷取。By defining the curve segments for different resolution levels, the present invention can obtain high-quality font output without having to pay particular attention to low or high resolution output devices. The font designer can subdivide into many curve segments between two adjacent feature points to define the formation of the curve segment between the two points. The finer the curve segment organization, the more it can provide high-resolution imaging, otherwise, the higher the layer The more curved sections of the tissue are more suitable for providing low-resolution imaging. For example, referring to the situation of Fig. 7 (3), if the resolution level L is the uppermost layer), only the curve segment of Cr (l) will be captured. If L is ΠΓ '(the middle layer), then Cr (2 ) And Cr (3) curve segments will be retrieved. If L is Π2Π (the lowest layer), then the different subdivided curve segments of Cr (3) and Cr (4) and Cr (5) will be retrieved.
圖四（4)示出如上所述之定義曲線段的流程，如方塊 180所示，本方法定義一條或多條二次貝茲曲線段，再如 方塊182所示，本方法指定每條曲線段所屬的曲線層級， 然後如方塊184所示，本方法決定是否被定義的曲線段已 經吻合了基本圖樣外形，如果沒有則如方塊186所示，本 方法繼續細分沒有吻合部分的曲線段，再回到方塊180用Figure 4 (4) shows the process of defining curve segments as described above. As shown in block 180, this method defines one or more quadratic Bezier curve segments. As shown in block 182, this method specifies each curve. The curve level to which the segment belongs. Then, as shown in block 184, the method determines whether the defined curve segment already conforms to the basic pattern shape. If not, as shown in block 186, the method continues to subdivide the curve segment that does not have a matching part, and then Back to block 180

As shown in block 18-8, the method stores all curve proportion values representing the curve segments and the curve levels to which they belong respectively in a tree-level curve level list. As shown in block 190, the method specifies the size of the point matrix. The range of is given to each curve level, and represents the range of the size of the point matrix governed by the number of levels. This point will be described below.
一旦所有的曲線段皆被定義後，就回到圖四（1 )， 如方塊87所述，本方法將基本圖樣切成一個或多個單跑段 掃瞄線區域，一個單跑段掃瞄區域是指在基本圖樣理的一 個實體區塊，因為它不含有空心，所以它可被單跑段掃瞄 線填滿。將基本圖樣切成單跑段掃瞄線區域可以簡化塗黑 填滿基本圖樣的工作，例如在圖八裡，就示出一個基本圖 樣的樣本194被切成四個單跑段掃瞄線區域，則區域1獨立 形成一個單跑段掃瞄線區域，它可以被箭頭196所示的單 跑段掃瞄線塗黑填滿，同樣地，圖樣中間部分1 94分成2和 3二個區域，分別可以被箭頭198 a及198 b的單跑段掃瞄 線塗黑填滿，因此，本方法僅需對每個被定義出來的單跑 段掃瞄線區域做出塗黑填滿的演算即可。 如圖四（5)方塊199所示，有關對每個單跑段掃瞄線 區域定義塗黑演算法，本方法首先如方塊200所示，指定Once all the curve segments have been defined, return to Figure Four (1). As described in block 87, this method cuts the basic pattern into one or more single-run scan line regions, and a single-run scan The area is a solid block in the basic pattern. Because it does not contain hollows, it can be filled by the single-scanning line. Cutting the basic pattern into the single-scanning scanning line area can simplify the work of filling the basic pattern with black. For example, in Figure 8, a sample of the basic pattern 194 is cut into four single-scanning scanning line areas. Then, area 1 independently forms a single-run scan line area, which can be filled with black by the single-run scan line shown by arrow 196. Similarly, the middle part of the pattern 1 94 is divided into 2 and 3 areas. It can be filled with black lines by the single-scanning lines of arrows 198 a and 198 b respectively. Therefore, this method only needs to make a black-filling calculation for each defined single-scanning line area. can. As shown in block 199 in Figure 4 (5), regarding the definition of the blackout algorithm for the scanning line area of each single run, the method firstly specifies the block as shown in block 200, specifying

一個單跑段碼給每個區域，再如方塊202所示，本方法確 定區域左右二邊曲線段的號碼’例如在圖八的情形’區 域’’1”是由{左曲線段=20 3&，右曲線段=2031>}所定義，其中 曲線段230a和203b係如前述之圖四（1)方塊80所定義， 同理，區域’’2”是由{左曲線段=2 04&，右曲線段=2041)}所定 義，以此類推。藉著這樣的建構，則塗黑圖樣1 94來顯像 的工作就比較容易，因為這時只要依序來分別塗黑填滿每 個單跑段掃瞄線區域即可。A single run segment code is given to each area, and as shown by block 202, this method determines the number of the left and right curve segments of the area 'for example, in the case of FIG. ;, The right curve segment = 2031 >}, where the curve segments 230a and 203b are defined as the box 80 in Figure 4 (1) above. Similarly, the area `` 2 '' is defined by {left curve segment = 2 04 & , Right curve segment = 2041)}, and so on. With this construction, the work of blackening the pattern 194 for development is easier, because at this time, it is only necessary to blacken and fill each scanning line area in order.
其次，方塊2 0 5是個可有可無的步驟，本方法將各個 單跑段掃瞄線區域以及它們的左右曲線段顯示在螢幕上， 讓字型設計人員可以驗證，如方塊206所示，字型設計人 員決定某個區域是否適當地被定義，如果沒有則如方塊 208所示，字型設計人員透過輔助工具適當地將此區域定 義，然後如方塊210所示，本方法於是儲存這個區域的左 右曲線段資料，俾供塗黑演算法使用，如方塊211所示，Secondly, block 205 is an optional step. This method displays the scanning line area of each single running segment and their left and right curve segments on the screen for font designers to verify, as shown in block 206. The font designer determines whether an area is properly defined. If not, it is shown in block 208. The font designer appropriately defines this area through auxiliary tools, and then shown in block 210. The method then saves this area. The left and right curve segment data is used for the blackout algorithm, as shown in block 211.
本方法決定是否所有的單跑段掃瞄線區域皆已定義，如果 沒有則跳到方塊19 9，繼續定義另一個尚未被定義的單跑 段掃瞄線區域，提供塗黑演算法使用，如果已如方塊2 11 所示，所有的單跑段掃瞄線區域皆已被定義，本方法於是 回到圖四（1)的方塊81。 其次如圖四（1 )方塊82所示，本方法定義及儲存第i 個基本圖樣之「關鍵點」，參照圖五以知曉關鍵點&至1(4This method determines whether all the scan line areas of the single run have been defined. If not, skip to box 19 9 and continue to define another scan line area of the single run that has not yet been defined to provide a blackout algorithm. If As shown in block 2 11, all the scanning line areas of the single run have been defined. The method then returns to block 81 in FIG. 4 (1). Secondly, as shown in block 82 of FIG. 4 (1), the method defines and stores the “key points” of the i-th basic pattern. Refer to FIG. 5 to know the key points & to 1 (4

是怎樣被定義的。關鍵點是用來定位以及從事局部變化基 本圖樣之形狀用，因此關鍵點的選取是依照基本圖樣之外 觀，以及能表現相似圖樣的特點來定義，關鍵點可由字型 設計人員透過輔助工具來選取，或者可依據語言描述的軟 體工具加予定義。關鍵點可選在基本圖樣的内部、邊線上 面、或其外部，使得可藉著移動關鍵點來控制基本圖樣的 局部形狀，一般而言，關鍵點通常被選在基本圖樣的起點 或終點上，或者基本圖樣突然改變方向的局部位置上，使 得改變關鍵點的位置，可以造成增長、拉大或縮小，或者 彎曲基本圖樣之部分區域的形狀，藉此特點可以修正基本 圖樣的形狀來逼近吻合文字理得各個相似圖樣，因此一個 圖樣至少需要兩個關鍵點，有關於移動關鍵點來改變基本 圖樣之形狀的方法將在下面有更完整的敘述。 其次如方塊82所示，當某個關鍵點被標示為『暗示情 報』時，則該點會被強迫座落在網格的特定位置上，並作 為重新計算特徵點位置及圖樣之外圍形狀的基礎，簡而言 之，標示關鍵點為『暗示情報』具有避免文字字型扭曲在 一起的優點，有關暗示情報的詳細說明將在以下敘述。How it is defined. The key points are used to locate and engage in the shape of the basic pattern of local changes. Therefore, the selection of key points is defined according to the appearance of the basic pattern and the characteristics that can represent similar patterns. The key points can be selected by font designers through auxiliary tools. , Or it can be defined based on the software tools described in the language. The key points can be selected inside, above the border, or outside the basic pattern, so that the local shape of the basic pattern can be controlled by moving the key points. Generally speaking, the key points are usually selected at the starting point or end point of the basic pattern. Or the basic pattern suddenly changes the direction of the local position, so that changing the position of key points can cause growth, enlargement or reduction, or bend the shape of a part of the basic pattern. With this feature, the shape of the basic pattern can be modified to approximate the text. Each similar pattern is processed, so a pattern needs at least two key points. The method of moving the key points to change the shape of the basic pattern will be described more fully below. Secondly, as shown in block 82, when a key point is marked as "suggested intelligence", the point will be forced to be located at a specific position on the grid and used as a recalculation of the feature point position and the outer shape of the pattern. Basically, in short, marking the key point as "suggested intelligence" has the advantage of avoiding distorted text fonts. A detailed description of hinted information will be described below.

In Figure 9 (1), 141a and 141b are two unmarked key points. At this time, the middle part will occupy two grids and cause a thickening phenomenon. This makes the quality worse, because the other parts only occupy the thickness of a grid, which is an inconsistent phenomenon. On the contrary, as shown in Figure 9 (2), when 141a and 141b are marked,

Of course, moving the marked key points to the center of the grid in the above example is just one example of using hinted information. Other options can also be used, such as forcing the key point to be located at the midpoint of the edge of the grid. The font designer can specify that the action of hinting information is only needed from that resolution level onwards, because beyond this resolution level, it is used for high-resolution development, so there is no need to deal with fine-tuning. For example, if the font designer specifies that level 1 is the level to initiate hinting information, then if the level is lower than that level, it is a low-resolution display. The key points marked must be moved to generate the hinting information processing and show its effect.
其次如方塊83所示，本方法定義並儲存至少一個基本 圖樣的寬度值，例如圖五有四個寬度值W1至W4被定義出 來。定義寬度值可由字型設計人員透過輔助工具來設定， 或者可依據語言描述的軟體工具加以定義。同理，寬度值 是用來控制基本圖樣的局部形狀，因此也可以藉由其值的Secondly, as shown in block 83, the method defines and stores the width value of at least one basic pattern. For example, in Figure 5, four width values W1 to W4 are defined. The definition width value can be set by font designers through auxiliary tools, or can be defined according to software tools described by the language. Similarly, the width value is used to control the local shape of the basic pattern, so you can also use its value

As shown in block 88, once all the basic patterns have been completely defined, the method stores the definition data of each basic pattern in the basic pattern database 15 (Figure 1 (2)), such as the i-th basic pattern. Number (ID), its key points, width values, equations for calculating feature points from key points and width values, curve ratio values are stored as a curve level list, and programs that provide blackout algorithms for output visualization are those definitions The data of the i-th basic pattern 'and the display program (Gi) of each basic pattern's pattern fingerprint (stored in box 79 of figure four (1)) and the script sentence (box 86) are stored in the basic pattern Library 15. Secondly, as shown in block 90, this method determines whether all the basic patterns have been completely defined and appropriately stored as executable programs. In other words, this method determines whether all the patterns in the text set have at least one basic pattern. To represent its shape, if not, the method jumps back to block 72 and continues to define another pattern in the manner described above. Once all the basic patterns have been fully defined, the basic pattern database contains a set of programs that can be used to display the shapes of all basic patterns. The display pattern of each basic pattern is related to its special pattern reference and The script sentences are related, that is, the basic pattern database contains a set of pre-defined basic pattern sets, which can be used to convert the external font data from

圖四（2)示出圖一（2)之轉換程式16用於將外圍字 型資料轉換成圖樣基礎字型資料的一般步驟。首先如方塊 130所示，擷取定義外圍字型資料之以直線段以及曲線段 組成的外圍線段，這些被計算機1擷取之外圍字型資料可 以整批或分批載錄至計算機的系統記憶體11，再如方塊 132所示，從被擷取之字型檔中選其中一字逐一轉換，如 方塊134所示，比對該字典18 (圖一（2 ))的資訊，字典 18儲存的資訊包含字碼、字體、製造商、每字對應的基本 圖樣數目、每個圖樣之相對座標等，從該資訊中挑選對應 該字知其中一個基本圖樣來逐一和該字的部分形狀作比 對。Fig. 4 (2) shows the general steps of the conversion program 16 of Fig. 1 (2) for converting the peripheral font data into the pattern basic font data. First, as shown in block 130, the peripheral line segments composed of straight line segments and curved line segments that define the peripheral font data are retrieved. These peripheral font data retrieved by the computer 1 can be recorded into the computer's system memory in batches or in batches. Body 11, and then as shown in block 132, select one of the words from the extracted font file to convert one by one. As shown in block 134, compare the information of the dictionary 18 (Figure 1 (2)) with the dictionary 18 to store The information includes the code, font, manufacturer, the number of basic patterns corresponding to each character, the relative coordinates of each pattern, etc. From this information, select one of the basic patterns corresponding to the character to compare one by one with the partial shape of the character .

As shown in block 140, the pattern fingerprint must match the pattern fingerprint defined by its corresponding basic pattern before the next step of the calculation process.
如方塊142所示，一旦該基本圖樣指紋被確認之後， 該基本圖樣預先定義的劇本句子就被擷取出來，再採用如 方塊13 6所示之圖樣指紋的特徵點位置來計算關鍵點位置 以及寬度值，一旦該基本圖樣之所有被預先定義之關鍵點 及寬度值皆依預存之劇本句子被推算出來之後，其次就如 方塊144所示，該基本圖樣之編碼就指定給該被選圖樣，As shown in block 142, once the fingerprint of the basic pattern is confirmed, the pre-defined script sentence of the basic pattern is extracted, and then the feature point positions of the pattern fingerprint shown in block 13 6 are used to calculate the key point positions and Width value. Once all the pre-defined key points and width values of the basic pattern are calculated from the pre-stored script sentences, the next step is as shown in block 144. The encoding of the basic pattern is assigned to the selected pattern.

If not, then start the pattern definition program repeatedly as described above until all the peripheral data have been converted into patterns. The program is stopped only after the font's explicit data and its implicit parameter values. The implicit parameter values include how to calculate the parameter values of the feature points from the key points and width values, and how to calculate the curve between them from the feature points. The curve scale value of the shape. Once the explicit and implicit parameter values of all these combined patterns are determined, these data are stored in the pattern base font database 17 and used as the text of the selected peripheral font in Figure 1 (2).

The process of character image development is exactly the reverse processing step of the above-mentioned automatic conversion construction technology. The steps in Figure 4 (6) are completed in the graphics basic font development program 20, which is used in computer 1 (Figure 1 (2)) to store the implicit and explicit font database outside the graphics basic font database. Parameter values, one by one, are suitable for high-quality imaging output with low or high resolution. As shown in block 300, when the method captures the text for development or printing in a general application, such as a word processing program, as shown in block 302, the method first determines the developing device or printer As shown in block 304, the corresponding curve scale values are pre-stored in the curve level list of each component pattern, which are just suitable for the use of the printer or the display device of the resolution level.

Therefore, as shown in block 312, the pattern is developed according to these The key points and width values obtained at the end are calculated. The calculation process is to find the position of the feature points from the key points and the width values, and then calculate the curve segment between adjacent feature points according to the curve proportion value extracted from the curve level list. The curve level list is made based on the resolution of the special output device. Finally, a blackout algorithm is used to fill the inner area of the pattern 'to produce a dot matrix image. ^ Because the mother pattern is cut into multiple single-run scanning lines. Area, the blackout algorithm simply fills the scan line area of each single run. For example, the grid of a point matrix is covered by more than 50% of the scan line area of a single run. The point matrix is blackened, or if the center point of the grid falls within the scan line area of a single run, the point matrix of the grid is also blacked out.

Each position on the button point defines a feature point, for example, the display area 402 starts with“ + The position indicated by '' is the defined feature point.
圖十一（1)至（3)示出本方法在CAD工具上定義關鍵點 及寬度值，在圖十一（1)中，字型設計人員從CAD工具的主 搁選n Add Key11 410下達命令，並移動十字游標至各個欲被 定義為關鍵點的位置上，再以按钮確定該位置來定義一個 關鍵點，例如顯示區402裡以π+π表示的位置就是被定義的 關鍵點。 同理，在圖十一（2)中，字型設計人員選擇n Add Thicknessn412下達命令，產生一個如圖十一（3)所示的視 窗414，然後字型設計人員在顯示區402移動十字游標取二 點418 及420，貝丨J>^lfAdd Thi ckness” 視窗裡n New Thickness”欄盒41 6裡會顯示它們之間的距離，若按 下” 0K”則以此距離值定義寬度值。Figures 11 (1) to (3) show that the method defines key points and width values on the CAD tool. In Figure 11 (1), the font designer selects Add Key11 410 from the main selection of the CAD tool Command, and move the cross cursor to each position to be defined as a key point, and then use the button to determine the position to define a key point. For example, the position indicated by π + π in the display area 402 is the defined key point. Similarly, in Figure 11 (2), the font designer selects n Add Thicknessn 412 to issue a command to generate a window 414 as shown in Figure 11 (3), and then the font designer moves the cross cursor in the display area 402. Take the two points 418 and 420. In the “New Thickness” window in the “New Addness” box, the distance between them will be displayed. If you press “0K”, the width value will be defined by this distance value.

示，剛開始時其形狀是一直線段，因為PA&PB連線是在共 線上，因此π 0’’的起始設定讓PA和匕之間的曲線段是一條直 線段，此後，字型設計人員開始移動Pi來逼近PA和1\之間的 曲線，產生一條逼近想要得到之曲線形狀的一條二次曲 線，並記下如圖七（1)所示的 (XrXL^xVL^x)，L^yVLJy))為層級π0’’ 的曲線比例 值。 如圖十二（3)所示，字型設計人員在曲線層級碼的方 塊422輸入層級’’ Γ’，開始定義層級’’ Γ’的曲線比例值，如 圖十二（4 )所示，想要得到的原始曲線形狀被分成二段，ΡΑ 和Pe以及Pe和匕二段，再如上所述在其間分別產生中間控制 點匕及已，並依上述步驟分別移動P2和？3用它們所決定的二 次曲線段分別逼近原始曲線形狀，並分別記下如圖七（2) 所示Cr(2)及Cr(3)為層級丨f 1Π的曲線比例值，依此反覆步 驟類推，於是產生愈高層級愈細密分段的各層級曲線比例 值。 如圖十二（5)所示，字型設計人員將每個層級所對應的解 像度範圍填入，字型設計人員使用n Add Level”視窗420裡 的解像度範圍顯示區432，在顯示區432列出曲線層級數以 及對應的解像度範圍，例如在圖十二（5)裡，字型設計人 員設定24x24點矩陣及其下尺寸係屬於曲線層級0，25x25 至64x64 尺寸之間的解像度屬於曲線層級1，通常，字型In the beginning, the shape is a straight line segment, because the PA & PB connection is on a collinear line, so the initial setting of π 0 '' makes the curve segment between PA and dagger a straight line segment. After that, the font design The person starts to move Pi to approach the curve between PA and 1 \, and generates a quadratic curve that approximates the shape of the curve that he wants, and writes down (XrXL ^ xVL ^ x) as shown in Figure 7 (1), L ^ yVLJy)) is the curve scale value of the level π0 ''. As shown in Fig. 12 (3), the font designer enters the level "Γ '" in block 422 of the curve level code, and starts to define the curve proportion value of the level "Γ', as shown in Fig. 12 (4). The original curve shape you want to get is divided into two sections, PA and Pe, and Pe and dagger. Then, as described above, the intermediate control points dagger and dagger are generated respectively, and P2 and? Are moved respectively according to the above steps. 3 Use the quadratic curve segments determined by them to approximate the original curve shape, respectively, and note down the curve proportion values of Cr (2) and Cr (3) as shown in Figure 7 (2), and repeat them accordingly. The steps are analogized, and then the curve proportion values of each level are divided into more detailed levels. As shown in Figure 12 (5), the font designer fills in the resolution range corresponding to each level. The font designer uses the resolution range display area 432 in the n Add Level window 420, and there are 432 columns in the display area. Show the number of curve levels and the corresponding resolution range. For example, in Figure 12 (5), the font designer sets the 24x24 point matrix and its lower dimensions to belong to the curve level 0. The resolution between the 25x25 to 64x64 dimensions belongs to the curve level 1. , Usually, font
