本發明是有關於一種調整方法和裝置，特別係關於一種自動調整筆劃的方法和裝置。The present invention relates to an adjustment method and device, and in particular to a method and device for automatically adjusting pen strokes.
根據亞洲國家使用標準編碼的字符數量，至少有數千字到數萬字，以台灣所使用的Big5規格就包括13,060個漢字，而以Unicode 15.0的規格，甚至收錄了97,058個漢字字碼。The number of characters encoded in standard formats used by Asian countries ranges from thousands to tens of thousands. The Big5 format used in Taiwan includes 13,060 Chinese characters, while the Unicode 15.0 format includes 97,058 Chinese character codes.
在數位系統上，要使用這些字符，就必須將每個字符製作出來，並放入各種規格定義好的字符代碼中，稱為碼本(codebook)。因此，若要於數位系統上使用新風格字體，需字體設計師做滿一個碼本的新風格字型，往往需要花費數年的時間才能完成。In order to use these characters on a digital system, each character must be produced and put into various character codes defined by specifications, called codebooks. Therefore, if a new style font is to be used on a digital system, a font designer needs to create a new style font that fills a codebook, which often takes several years to complete.
因此，如何加快新風格字體的產生，以解決上述的問題，乃為此一業界亟待解決的問題。Therefore, how to speed up the production of new style fonts to solve the above problems is an issue that the industry needs to solve urgently.

傳統上，若要於數位系統上使用新風格字體，需字體設計師親自做滿一個完整規範碼本的新風格字型，不僅相當耗費時間亦不具時效，在推出時，設計的新風格字體可能已不受消費者所喜愛。因此，本案藉由人工智慧，利用字體設計師親自設計出具新風格字體的字做為代表字，將已存在的風格字體中字體設計師未設計過的字，渲染成具新風格字體的字，同時根據被渲染成新風格字體的字，從筆劃庫中挑選出對應筆劃，自動微調所挑出筆劃的參數，如筆劃位置以及筆劃大小，來符合新風格字體的字，以完善新風格字體的字。由於本案無須字體設計師親自做滿一個碼本具新風格字體的字，因此可節省大量設計時間，更具時效性。Traditionally, if you want to use a new style font on a digital system, the font designer needs to personally create a new style font with a complete standard codebook, which is not only very time-consuming but also not timely. When the new style font is launched, the designed new style font may no longer be liked by consumers. Therefore, this case uses artificial intelligence to use the characters designed by the font designer himself to create a new style font as representative characters, and renders the characters in the existing style font that the font designer has not designed into the new style font. At the same time, according to the characters rendered into the new style font, the corresponding strokes are selected from the stroke library, and the parameters of the selected strokes, such as stroke position and stroke size, are automatically fine-tuned to match the characters in the new style font to improve the characters in the new style font. Since this case does not require the font designer to personally create a full code book of new style fonts, it can save a lot of design time and be more timely.

The input-output unit 13 can be a touch screen or a handwriting board, but the present invention is not limited thereto.
第2圖所示為根據本案一些實施例產生一具新風格字體的方法流程圖。產生具新風格字體的方法200可應用第1圖所示的自動調整匹配筆劃的裝置10，來調整組成新風格字體的筆劃，而無須設計師手動執行，因此可節省大量時間。FIG. 2 is a flow chart of a method for generating a new style font according to some embodiments of the present invention. The method 200 for generating a new style font can apply the device 10 for automatically adjusting matching strokes shown in FIG. 1 to adjust the strokes constituting the new style font without the need for the designer to perform manual operation, thereby saving a lot of time.
產生具新風格字體的方法200，首先於步驟201，產生多種筆劃，其中該些筆劃中的每一者均具有一新風格字體的外觀。在一較佳實施例中，一字體設計師藉由構思欲呈現字體的風格外觀，設計出一新風格字體，並根據此新風格字體，繪製出組成此新風格字體所需的不同筆劃。在一較佳實施例中，字體設計師可於輸入輸出單元13上繪製新風格字體的筆劃資料，並儲存於記憶體11中，以形成一具新風格字體外觀的筆劃資料庫14。The method 200 for generating a font with a new style first generates a plurality of strokes in step 201, wherein each of the strokes has the appearance of a new style font. In a preferred embodiment, a font designer designs a new style font by conceiving the appearance of a font style, and draws different strokes required to form the new style font according to the new style font. In a preferred embodiment, the font designer can draw the stroke data of the new style font on the input-output unit 13 and store it in the memory 11 to form a stroke database 14 of the appearance of the new style font.
接著於步驟202，設置每一筆劃的外框以及關鍵參數組。在一實施例中，根據輸入的多種新風格筆劃，賦與該多種筆劃每一者的對應編號，並以數學式描述筆劃外框。在一些實施例中，所使用的數學式為貝茲曲線用來描述筆劃輪廓的外框。在一些實施例中，當字體設計師於電子裝置的輸入模組上繪製新風格字體的筆劃資料後，自動調整筆劃裝置10可據此筆劃資料，使用貝茲曲線描述此筆劃輪廓的外框，並設置每一筆劃的關鍵參數組，其中每個筆劃至少有兩個關鍵參數組。第3圖所示為根據本案一實施例對一「人」字的筆劃設置關鍵參數組之概略圖示。在此實施例中，自動調整筆劃裝置10設置包括由貝茲曲線所描述「人」字筆劃輪廓的外框。「人」字的第一筆劃，亦即左側筆劃，描述筆劃起始點位置及終點位置的至少二控制點參數A1以及A2，以及描述寬度的寬度參數W1。「人」字的第二筆劃，亦即右側筆劃，描述筆劃起始點位置及終點位置的至少二控制點參數B1以及B2，以及描述寬度的寬度參數W2。Then, in step 202, the outline and key parameter set of each stroke are set. In one embodiment, a corresponding number is assigned to each of the multiple strokes of the new style input, and the stroke outline is described by a mathematical formula. In some embodiments, the mathematical formula used is a Bezier curve to describe the outline of the stroke. In some embodiments, after the font designer draws the stroke data of the new style font on the input module of the electronic device, the automatic stroke adjustment device 10 can use the Bezier curve to describe the outline of the stroke according to the stroke data, and set the key parameter set of each stroke, wherein each stroke has at least two key parameter sets. FIG. 3 is a schematic diagram showing a key parameter set for a stroke of a character "人" according to an embodiment of the present invention. In this embodiment, the automatic stroke adjustment device 10 is provided with an outer frame of the stroke outline of the character "人" described by a Bezier curve. The first stroke of the character "人", i.e., the left stroke, describes at least two control point parameters A1 and A2 of the stroke starting point position and the end point position, and a width parameter W1 describing the width. The second stroke of the character "人", i.e., the right stroke, describes at least two control point parameters B1 and B2 of the stroke starting point position and the end point position, and a width parameter W2 describing the width.
接著於步驟203，形成一基礎字集。在一實施例中，利用步驟201及202產生的筆劃組成具有新風格字體的多個不同字，此些字都具有新風格字體，用以作為後續提取新風格特徵時使用的基礎字集，並儲存於記憶體11中。Then, in step 203, a basic character set is formed. In one embodiment, the strokes generated in steps 201 and 202 are used to form a plurality of different characters with a new style font. These characters all have a new style font and are used as a basic character set for subsequent extraction of new style features and are stored in the memory 11.
接著於步驟204，根據基礎字集產出具有新風格字體外觀的一新字，此新字為設計師未設計的字。在一實施例中，可透過輸入輸出單元13輸入一第一字以及一第二字。其中第一字具有已存在風格字體的外觀，非基礎字集中的字。第二字具有新風格字體的外觀，為基礎字集中的其中一字。第一字是用以作為後續渲染第一字產生融合新風格字體後第一字的字體架構參考來源，字體架構為文字的筆劃的穿插關係。在一些實施例中，所選擇具有的已存在風格字體外觀可為黑體，但本案不以黑體為限。使用第一字的字體架構特徵以及第二字的風格特徵進行融合，渲染第一字以產生融合新風格字體外觀的第一字。在一些實施例中，亦即提取第一字的字體架構特徵，以及提取第二字的風格特徵，以融合第一字的字體架構特徵以及第二字的風格特徵，來渲染第一字以產生具有新風格字體外觀的第一字。Then in step 204, a new character with a new style font appearance is generated based on the basic character set. This new character is a character that has not been designed by the designer. In one embodiment, a first character and a second character can be input through the input and output unit 13. The first character has the appearance of an existing style font and is not a character in the basic character set. The second character has the appearance of a new style font and is one of the characters in the basic character set. The first character is used as a font structure reference source for the first character after the subsequent rendering of the first character to generate a fusion of the new style font. The font structure is the interlaced relationship of the strokes of the text. In some embodiments, the selected existing style font appearance can be bold, but the present case is not limited to bold. The font structure characteristics of the first character and the style characteristics of the second character are used for fusion, and the first character is rendered to generate the first character with a fusion of the new style font appearance. In some embodiments, the font structure features of the first character are extracted, and the style features of the second character are extracted, so as to fuse the font structure features of the first character and the style features of the second character to render the first character to generate the first character with a new style font appearance.
接著於步驟205，選擇可組成新字所有可能匹配的筆劃。根據具新風格字體外觀的第一字，從記憶體11的筆劃資料庫14中選擇可組成第一字所有可能匹配的筆劃。因為，所形成的第一字為字體設計師在設計新風格字體時未設計過的字，而其中所使用之筆劃為筆劃資料庫14中形成基礎字集中的筆劃，因此筆劃的大小或是筆劃位置未必適用於步驟204產出的具新風格字體外觀的第一字。Then in step 205, all possible matching strokes that can form a new character are selected. Based on the first character with the new style font appearance, all possible matching strokes that can form the first character are selected from the stroke database 14 of the memory 11. Because the first character formed is a character that the font designer has not designed when designing the new style font, and the strokes used therein are the strokes in the stroke database 14 that form the basic character set, so the size of the strokes or the stroke position may not be applicable to the first character with the new style font appearance generated in step 204.
因此，於步驟206，自動調整匹配筆劃的參數。將匹配筆劃配置於步驟204所產出具有新風格字體外觀第一字的適配過程中，更自動調整匹配筆劃的參數。在一些實施例中，可對描述筆劃起始點位置及終點位置的至少二控制點參數，以及描述筆劃寬度的寬度參數進行調整，讓第一字字體外觀的整體風格更符合步驟204所產出的具有新風格字體外觀的第一字。其中調整匹配筆劃參數的過程另揭示在第4圖中。Therefore, in step 206, the parameters of the matching strokes are automatically adjusted. In the adaptation process of the first character with the new style font appearance generated in step 204, the parameters of the matching strokes are further automatically adjusted. In some embodiments, at least two control point parameters describing the stroke starting point position and the end point position, and the width parameter describing the stroke width can be adjusted to make the overall style of the first character font appearance more consistent with the first character with the new style font appearance generated in step 204. The process of adjusting the matching stroke parameters is further disclosed in FIG. 4.
最後於步驟207，由設計師進行人工檢視第一字字體外觀的整體風格是否符合新風格字體外觀。若有必要，設計師亦可再次進行第一字微調。Finally, in step 207, the designer manually checks whether the overall style of the first character font appearance conforms to the new style font appearance. If necessary, the designer can also fine-tune the first character again.
第4圖所示為根據本案一些實施例自動調整匹配筆劃的方法流程圖。自動調整匹配筆劃的方法300可應用於第1圖所示的自動調整筆劃裝置10中。處理器12可自記憶體11存取並執行至少一指令，以實施自動調整匹配筆劃的方法300，用以讓第一字字體外觀的整體風格更符合步驟204所產出的具有新風格字體外觀的第一字。FIG. 4 is a flow chart of a method for automatically adjusting matching strokes according to some embodiments of the present invention. The method 300 for automatically adjusting matching strokes can be applied to the automatic stroke adjustment device 10 shown in FIG. 1 . The processor 12 can access and execute at least one instruction from the memory 11 to implement the method 300 for automatically adjusting matching strokes, so as to make the overall style of the first character font appearance more consistent with the first character with the new style font appearance generated in step 204.
自動調整匹配筆劃的方法300，首先於步驟301，配置筆劃至新字的對應筆劃位置上。在一實施例中，將從筆劃資料庫14中選擇出可組成第一字的匹配筆劃，自動配置於步驟204所產出具有新風格字體外觀的第一字中的對應筆劃位置上。在一些實施例中，第5A圖所示為一具有新風格字體外觀的「予」字。第5B圖所示為匹配「予」字的6個筆劃。第5C圖所示為分別框定對應筆劃的位置。第5D圖所示自動配置筆劃於對應筆劃位置上。依此，若步驟204所產出具有新風格字體外觀的第一字為如第5A圖所示的「予」字401，本案根據「予」字401比對筆劃資料庫14中設計師設計的筆劃，選出如第5B圖所示匹配「予」字401的6個筆劃403B-408B，並對「予」字401的6個筆劃403B-408B，如第5C圖所示，分別框定6個筆劃403B-408B的對應筆劃位置403A-408A。在一些實施例中，第5B圖所示的筆劃「、」403B對應第5C圖所示框定位置403A。第5B圖所示的筆劃「ー」408B對應第5C圖所示框定位置408A。其餘之筆劃可依此類推。當選出如第5B圖所示匹配「予」字401的6個筆劃403B-408B，並如第5C圖所示，框定6個筆劃403B-408B的對應筆劃位置403A-408A後，如第5D圖所示，自動將6個筆劃403B-408B分別配置於6個對應筆劃位置403A-408A上。在一些實施例中，筆劃「、」403B被自動配置於對應筆劃位置403A上。其餘筆劃404B-408B可依此類推分別配置於對應筆劃位置404A-408A上。The method 300 for automatically adjusting matching strokes first configures the strokes to the corresponding stroke positions of the new character in step 301. In one embodiment, matching strokes that can form the first character are selected from the stroke database 14 and automatically configured to the corresponding stroke positions in the first character with the new style font appearance produced in step 204. In some embodiments, FIG. 5A shows a character "予" with the new style font appearance. FIG. 5B shows 6 matching strokes of the character "予". FIG. 5C shows the positions of the corresponding strokes framed respectively. FIG. 5D shows that the strokes are automatically configured at the corresponding stroke positions. Accordingly, if the first character with the appearance of the new style font generated in step 204 is the character "予" 401 as shown in FIG. 5A, the present case compares the strokes designed by the designer in the stroke database 14 with the character "予" 401, selects the six strokes 403B-408B that match the character "予" 401 as shown in FIG. 5B, and respectively frames the corresponding stroke positions 403A-408A of the six strokes 403B-408B of the character "予" 401 as shown in FIG. 5C. In some embodiments, the stroke "、" 403B shown in FIG. 5B corresponds to the framed position 403A shown in FIG. 5C. The stroke "ー" 408B shown in FIG. 5B corresponds to the framed position 408A shown in FIG. 5C. The rest of the strokes can be arranged in the same manner. When the six strokes 403B-408B matching the character "予" 401 are selected as shown in FIG. 5B, and the corresponding stroke positions 403A-408A of the six strokes 403B-408B are framed as shown in FIG. 5C, the six strokes 403B-408B are automatically arranged on the six corresponding stroke positions 403A-408A as shown in FIG. 5D. In some embodiments, the stroke "、" 403B is automatically arranged on the corresponding stroke position 403A. The rest of the strokes 404B-408B can be arranged on the corresponding stroke positions 404A-408A in the same manner.
在一些實施例中，也就是說，由步驟204所產出具有新風格字體外觀的「予」字401，每一筆劃均有一特定筆劃大小，亦即原圖筆劃大小。但因為步驟301是從筆劃資料庫14中選擇出可組成「予」字401的6個筆劃403B-408B，此6個筆劃403B-408B和對應原圖筆劃大小會有落差。因此本案於後續步驟中，會根據「予」字401每一筆劃之原圖筆劃大小對此6個筆劃403B-408B進行調整，以讓調整後6個筆劃403B-408B更貼近於原圖筆劃大小。In some embodiments, that is, each stroke of the character "予" 401 with the new style font appearance generated by step 204 has a specific stroke size, that is, the stroke size of the original image. However, because step 301 selects 6 strokes 403B-408B that can form the character "予" 401 from the stroke database 14, there is a difference between the size of these 6 strokes 403B-408B and the corresponding stroke size of the original image. Therefore, in the subsequent steps of this case, these 6 strokes 403B-408B will be adjusted according to the stroke size of each stroke of the character "予" 401 in the original image, so that the adjusted 6 strokes 403B-408B are closer to the stroke size of the original image.
在一些實施例中，自動調整筆劃裝置10可根據筆劃403B-408B資料，設置每一筆劃403B-408B的關鍵參數組，其中每個筆劃403B-408B，至少包括由貝茲曲線所描述筆劃輪廓的外框，描述筆劃起始點位置及終點位置的至少二控制點參數，以及描述寬度的寬度參數。本案即是藉由調整每一筆劃403B-408B的控制點參數和寬度參數，對筆劃403B-408B進行調整，以貼近於原圖筆劃大小。In some embodiments, the automatic stroke adjustment device 10 can set a key parameter set of each stroke 403B-408B according to the stroke 403B-408B data, wherein each stroke 403B-408B at least includes an outer frame of the stroke outline described by a Bezier curve, at least two control point parameters describing the stroke start point position and the end point position, and a width parameter describing the width. In this case, the stroke 403B-408B is adjusted by adjusting the control point parameters and the width parameter of each stroke 403B-408B to be close to the stroke size of the original image.
於步驟302，調整對應筆劃的控制點參數以修正筆劃外觀。在一些實施例中，如第6圖所示，在筆劃「、」403B被自動配置於對應筆劃位置403A後，調整筆劃「、」403B控制點參數。在一些實施例中，可依循一第一方向調整筆劃「、」403B之X方向值以及Y方向值，以拉伸修正筆劃「、」403B外觀。In step 302, the control point parameters of the corresponding stroke are adjusted to correct the stroke appearance. In some embodiments, as shown in FIG. 6, after the stroke "," 403B is automatically configured at the corresponding stroke position 403A, the control point parameters of the stroke "," 403B are adjusted. In some embodiments, the X-direction value and the Y-direction value of the stroke "," 403B can be adjusted in a first direction to stretch and correct the appearance of the stroke "," 403B.
於步驟303，比對修正後筆劃外觀與對應的原圖筆劃外觀的疊合比率。在一些實施例中，係將拉伸修正後的筆劃「、」403B的外觀和對應筆劃位置403A上的原圖筆劃403C的外觀疊合後進行比對，計算拉伸修正後筆劃「、」403B的外觀疊合於原圖筆劃403C的一疊合比率。在一些實施例中，在依循第一方向拉伸修正筆劃「、」403B之外觀後，在和原圖筆劃403C的外觀疊合比對後，若產生的疊合比率下降，表示所依循拉伸修正的第一方向為錯誤方向。在一些實施例中，於步驟303中更可記錄此次拉伸修正的第一方向為錯誤方向，避免再次依此方向進行拉伸修正。In step 303, the overlap ratio of the corrected stroke appearance is compared with the corresponding original stroke appearance. In some embodiments, the appearance of the corrected stroke "," 403B is overlapped with the appearance of the original stroke 403C at the corresponding stroke position 403A and then compared, and an overlap ratio of the corrected stroke "," 403B overlapped with the original stroke 403C is calculated. In some embodiments, after the appearance of the corrected stroke "," 403B is corrected by stretching in a first direction, after being overlapped and compared with the appearance of the original stroke 403C, if the generated overlap ratio decreases, it means that the first direction of the corrected stroke is an incorrect direction. In some embodiments, in step 303, the first direction of the stretch correction can be recorded as an incorrect direction to avoid stretch correction in this direction again.
於步驟304，調整對應筆劃的寬度參數以修正筆劃面積。在一些實施例中，如第6圖所示，在筆劃「、」403B被自動配置於對應筆劃位置403A後，調整筆劃「、」403B的寬度參數，以修正筆劃「、」403B面積。In step 304, the width parameter of the corresponding stroke is adjusted to correct the stroke area. In some embodiments, as shown in FIG. 6, after the stroke "," 403B is automatically configured at the corresponding stroke position 403A, the width parameter of the stroke "," 403B is adjusted to correct the stroke area "," 403B.
於步驟305，比對修正後筆劃面積與對應的原圖筆劃面積比值。在一些實施例中，係將修正後的筆劃「、」403B的面積和對應筆劃位置403A上的原圖筆劃403C的面積進行比對，計算面積比值，判定修正後的筆劃「、」403B的面積是否接近於對應筆劃位置403A上的原圖筆劃403C的面積。藉由步驟302-305，可讓修正後的筆劃「、」403B的外觀近於原圖筆劃403C。在一些實施例中，步驟302-305會被重複執行，直到疊合比率以及面積比值不再變化或變化小於一特定值為止。在另一些實施例中，亦可設置疊合比率以及面積比值的門檻值，達到此門檻值即不再進行筆劃調整。In step 305, the area ratio of the corrected stroke is compared with the area ratio of the corresponding original stroke. In some embodiments, the area of the corrected stroke "," 403B is compared with the area of the original stroke 403C at the corresponding stroke position 403A, and the area ratio is calculated to determine whether the area of the corrected stroke "," 403B is close to the area of the original stroke 403C at the corresponding stroke position 403A. Through steps 302-305, the appearance of the corrected stroke "," 403B can be close to the original stroke 403C. In some embodiments, steps 302-305 are repeatedly executed until the overlap ratio and the area ratio do not change or change less than a specific value. In other embodiments, a threshold value of the overlap ratio and the area ratio can also be set, and when the threshold value is reached, the stroke adjustment is no longer performed.
依此，於步驟306，判斷疊合比率以及面積比值是否不再變化或小於一特定值。若疊合比率以及面積比值於調整後不再變化或小於一特定值。執行步驟307，完成筆劃的調整以及進行調整後筆劃組字。在一實施例中，若筆劃「、」403B完成調整後，即可根據調整後的控制點參數以及寬度參數，進行筆劃「、」403B組字。反之，若疊合比率以及面積比值於調整後會再變化或不小於一特定值。則再次執行步驟302-305，再次調整對應筆劃的控制點參數和寬度參數修正筆劃外觀以及面積藉以趨近於原圖筆劃403C。「予」字401的其餘筆劃可依上述之流程進行調整，藉以完成「予」字401。而其他字的筆劃也可依上述流程進行調整。Accordingly, in step 306, determine whether the overlap ratio and the area ratio no longer change or are less than a specific value. If the overlap ratio and the area ratio no longer change or are less than a specific value after adjustment. Execute step 307 to complete the adjustment of the stroke and to form characters with the adjusted strokes. In one embodiment, if the stroke "," 403B is adjusted, the stroke "," 403B can be formed into characters based on the adjusted control point parameters and width parameters. On the contrary, if the overlap ratio and the area ratio will change again or be not less than a specific value after adjustment. Then, steps 302-305 are executed again, and the control point parameters and width parameters of the corresponding stroke are adjusted again to correct the stroke appearance and area so as to be close to the original stroke 403C. The remaining strokes of the character "予" 401 can be adjusted according to the above process to complete the character "予" 401. The strokes of other characters can also be adjusted according to the above process.
接著於步驟308，產生各筆劃調整過後的控制點參數以及寬度參數。據此即可依所產生各筆劃的控制點參數以及寬度參數組成具新風格字體的字。Then, in step 308, the control point parameters and width parameters of each stroke after adjustment are generated. According to this, a character with a new style font can be composed according to the generated control point parameters and width parameters of each stroke.
由上述本案之實施方式可知，其主要係用以改進以往在根據字體設計師設計之基礎字集生成一基礎字集外具有新風格字體外觀的新字後，仍需字體設計師對所生成新字的筆劃或位置進行微調以更符合新風格字體，相當耗費時間成本。因此，本案提出一種筆劃調整方法，在根據所生成的新字選擇出對應的筆劃後，本案筆劃調整方法會將所選擇出的筆劃疊合在所生成新字的對應筆劃的原圖筆劃上，並根據和所生成新字的對應筆劃的原圖筆劃間的疊合比率以及面積比值，調整選擇出筆劃的控制點參數和寬度參數，來修正選擇出筆劃的外觀以及選擇出筆劃的面積，藉以讓調整後的筆劃趨近於原圖筆劃。由於本案的筆劃調整方法，無須設計師手動調整選擇出的筆劃，因此可節省大量設計時間。From the implementation method of the present case described above, it can be seen that it is mainly used to improve the previous practice of generating a new character with a new style font appearance outside the basic character set designed by the font designer, and the font designer still needs to fine-tune the strokes or position of the generated new character to better conform to the new style font, which is quite time-consuming. Therefore, this case proposes a stroke adjustment method. After selecting the corresponding stroke according to the generated new character, the stroke adjustment method of this case will overlap the selected stroke on the original stroke of the corresponding stroke of the generated new character, and adjust the control point parameters and width parameters of the selected stroke according to the overlap ratio and area ratio between the original stroke of the corresponding stroke of the generated new character to correct the appearance of the selected stroke and the area of the selected stroke, so as to make the adjusted stroke close to the original stroke. Because the stroke adjustment method of this case does not require the designer to manually adjust the selected stroke, it can save a lot of design time.
