通过定义扩展大字体文件,可以减小复合 Kanji 字符的大小。扩展大字体使用子形编码,后面紧跟一个 0。 扩展大字体文件的第一行与普通的大字体文件一样。文件中其他行的格式如下所示: *0,5,font-name character-height, 0, modes, character-width,0 . . . *shape-number,defbytes,shape-name . code,0,primitive#,basepoint-x,basepoint-y,width,height, . . code,0,primitive#,basepoint-x,basepoint-y,width,height, . terminator 下表介绍大字体定义文件中的字段:
为达到一定的比例因子,程序将字体原型缩放为某个平方单位,然后将其乘以宽度和高度得到字符的形。大字体形定义文件中字符代码(形编号)的值最大可到 65535。下表描述了扩展大字体文件中的字段。
下图是一个 16 x 16 点阵的样例,可用于设计扩展大字体(例如 Kanji 字符)。在此样例中,点之间的距离为一个单位。标注指向正方形单位。 Kanji 字符的方形矩阵 下图是 Kanji 字符的样例。每个字符占据一个 M×N 矩阵(矩阵不必为方阵),与上图所示矩阵类似。每个图例上的编号是相关联的形编号。 Kanji 字符的样例 下图展示了 Kanji 字体原型。 Kanji 原形样例 注: 并非所有字体都定义在方阵中,有些字体是用长方形矩阵定义的。
