Windows GDI三元光栅操作 2011-03-06 15:19:58| 分类： windows程序设计 | 标签： |字号大中小 订阅
Windows 绘图是在DC(device context)中进行。所有的的位图操作都会涉及到 源位图，目的位图和当前DC的画刷。这三者之间可以进行 逻辑与，逻辑或，逻辑非和逻辑异或 操作。三者的不同组合一共构成了256种操作的结果，也就是有256种三元光栅操作。使用BitBlt、PatBlt和StretchBlt时都会使用到这三钟光栅操作码,即ROP 码，像SRCCOPY ，PATPAINT ，SRCAND 等。这256种光栅操作在windows种由四个字节定义，他们都是规定好的。其高位字（high-order word）是布尔操作索引，其低位字（low-order word）是操作码。16位的操作索引从0开始。具体的十六进制值如下所示，你会发现这些编码是从0x00 － 0xFF.
