求助:如何把这段代码中指针变直?这里的指针总是弯的
作者: 523066680    时间: 2010-6-14 18:06

我记得指针时钟有人发过呀!#@¥@#¥……

哈哈 其实这个已经不弯了。两点之间构成一直线,而这个点太粗啦~

像这个:
000
      000
             000

上次qzwqzw弄了个改注册表之类的可以控制 字符大小,那个顶~

如 4 楼所述, 基于显示硬件的光栅式显示原理, 除了水平方向和垂直方向的直线外, 在显示硬件上是没有绝对的直线的, 非水平和垂直方向的直线只能用水平线段和垂直线段的组合构成折线来近似显现, 目前我所知 直线最好的画法 是 Bresenham 算法, 请参考
