freetype 使用小結
freetype是乙個完全開源的 可擴充套件 可定製且可移植的字型引擎，它提供truetype字型驅動的實現統一的介面來訪問多種字型格式檔案，包括點陣字 truetype opentype type1 cid cff windows fon fnt x11 pcf等。freetype函式庫具有以下特...
初探freetype字型庫
文字的顯示依賴於字型字型檔，大致的字型字型檔分為點陣字型檔 筆畫字型檔和輪廓字型檔。點陣字型檔 缺點比較明顯，縮放存在鋸齒，渲染旋轉等操作相對複雜，且效果不理想，先大多用在嵌入式行業 基本拋棄 常見格式有bdf，pcf，fnt，hbf，hzf等。筆畫字型 不討論。輪廓字型 即向量字型，利用字型輪廓及...
freetype的使用及總結
總結 1 首先建立乙個庫 2 根據字型檔案得到face object 3 設定字型大小及第乙個座標值 4 載入face得到字型的glyph及buffer 5 顯示 每次顯示乙個字元都是根據前乙個字元的glyph得到下乙個字元座標的原點值，這樣方便顯示 include include include ...
