for(i=0; i
for(k=0; k<8; k++)

g.drawLine(x + i * 8 + k, y + j, x + i * 8 + k, y + j);

}
}
n就是表示整个宽度需要的字节数，由于宽度为24，故需要3个字节表示。j记录纵向（高度）位置。代码的处理，就是通过一个画线函数进行的。每次以字节为单位(变量k处理)，对“1”进行检测，检测到1后，记录k的位置。
【调用方法】
CustomFont主要用于GameCanvas派生的类。在继承GameCanvas的类中：
(1)声明对象
[html]
private CustomFont cf;
(2) 初始化对象(在构造函数中)
[html]
cf = new CustomFont();
(3) 调用方法(画字符串passwd)
[html]
for(int i=0; i
cf.drawmat(this, graphics, cf.font24x48[passwd.charAt(i)-' '], 24, 48, (width-6*24)/2+i*24, (height-48)/3, Color.WHITE);
}
【效果】
图2中，框中的文字就是通过绘制得到的。
