光栅操作码:BitBlt之dwRop
我叫Raster Operater, 这名不是白叫的,下面来研究一下API函数BitBlt.
BitBlt中最难理解的就是dwRop,不光难记,API浏览器里还不全.
以下是《三元光栅操作》,很全的.
http://www.vchome.net/tech/graphics/graph26.htm
看完之后也觉得没什么,其中高字是索引,
令(画刷)P=0xF0, (源)S=0xCC, (目标)D=0xAA, 进行所需的运算, 结果就是索引.
索引*0x10000就是dwRop.低字不用管他.
低字古里古怪的,我找不到一点规律.但据我所知,他没有任何作用.
现在我都不用API常数中的这些值了,直接用PSD着三个值算.也挺简单的.
可能高手早知道了,我还在这里唠叨.....见笑了.
另:dwRop的低字总该有些意义的.有谁知道吗?
不至于吧,这么冷清?
还是标题太没吸引里了?
自己先顶一下.
陨落雕和Zyl两位应该会有些说法，我。。。没话讲。。。
//dwRop
[in] Specifies both foreground and background ternary raster operation codes (ROPs) that the function uses to control the combination of source and destination data. The background raster operation code is stored in the high-order byte of the high-order word of this value; the foreground raster operation code is stored in the low-order byte of the high-order word of this value;
**the low-order word of this value is ignored, and should be zero.**
我也觉得低位字似乎没什么用。
寻找资料ing
我也不知道怎么用
但基本的256种足够了

Public Const NOMIRRORBITMAP As Long = &H80000000
其实这样就行了：
Const ROP_P=0xF00000
Const ROP_S=0xCC0000
Const ROP_D=0xAA0000
Const ROP_PDSox = (ROP_D OR ROP_S) XOR ROP_P
随叫随到,哈哈....
//Const ROP_PDSox = (ROP_D OR ROP_S) XOR ROP_P
是呀，本来就是这样定义的嘛 :)

the low-order word of this value is ignored, and should be zero.
低字被忽略，并且可以为零。
既然是忽略，还要弄一些奇奇怪怪的数做什么。
不知道微软在弄什么玄虚。
但这个是MaskBlt成员函数的dwRop参数说明 :D
不知道，我说的MaskBlt是被封装在MFC的CDC类中的成员函数。不过觉得没区别。
::Bitblt中有这样一段说明：
Rop3: This parameter can be any one of 256 ternary raster-operation values
说明应该只有256种。我也不知道其低位“操作码”的含义了
呵呵，散分了。
我开这个帖，本来就是想散分的。
双星的我就不给分了，不介意吧。
