字體設計基礎----線稿的數字化_字體設計教程

　　Digitizing sketches. When the handmade sketches on paper are ready to be scanned, take care of digitizing them in a proper way. More specifically, take care while converting your scanned image manually with a Bezier based pen tool. Too many points on a character, or points at the wrong position can have a negative influence at your font.

　　線稿的數字化。在紙上畫好線稿之后就可以掃描了，這時候要開始要注意，要用正確的方法將其數字化。說的更明確一點，在你用貝賽線鋼筆工具手工描摹你的線稿的時候，要留神。一個字符如果有太多的節點，或者是節點放置在不正確的位置上，都會給你的字體帶來負面的影響。

　　Too many points (=nodes) can not only cause technical problems -e.g. the printer can't print the font anymore- but it is also much harder to control the shapes of a character. Controlling a curve between two nodes is much easier than changing a curve with twelve nodes. Of course it's possible, but it will not end up in a fluent form.

　　過多的節點不僅僅會導致技術上的麻煩，例如打印機無法打印輸出，還會使得字符的外形更加難于控制。在兩個節點之間控制一條曲線，要遠遠容易過操縱一條有12個節點的曲線。當然這并非不可以，但多余的節點必然會導致外形的不平滑。

　　Having the nodes at the wrong position can cause technical problems -e.g. it's impossible to hint the font perfectly- but also practically it is recommendable to put nodes at extreme positions at your glyph. For example, digitizing an 'o' would only need 8 nodes. Four at the outer form, four at the counter form. Putting nodes at extreme positions (most top & down, most left & right) means the BCP (Bezier Control Point) will always be totally horizontal or vertical. In that case they are much easier to control. In most software programs you can use shift key to keep the BCP totally horizontal or vertical.

　　節點放置在錯誤的地方也會導致技術問題，例如無法實現字符在屏幕小字號下的完美顯示（hinting-在計算機屏幕上顯示小字號時的優化顯示技術，是設計者嵌入字體內部的提示信息）。建議是，把節點放置在字符的"頂點"位置。舉例說明，用貝賽線繪制一個“O”要用到8個節點。外面4個，內部的字懷4個。將節點放置在頂點（最上點、最下點、最左點和最右點），意味著BCP（貝賽線控制點）將全部是水平或者垂直的。這樣它們就非常易于控制。在大多數的軟件中，你都可以通過shift鍵來將BCP（貝賽線控制點）的移動限制在水平或垂直方向上。
