谁有源码啊,高分征集(关于GDI的)

[kane_yj]

想实现动画效果的位图显示,譬如发牌、出牌时候的动画;
谁有1、透明位图的显示；2、内存绘图的代码；3、拖动位图移动的代码
涉及GDI函数：BitBlt、MaskBlt 、TransBitBlt()、、、、

int nWidthDest,
int hHeightDest,
HDC hdcSrc,
int nXOriginSrc,
int nYOriginSrc,
int nWidthSrc,
int nHeightSrc,
UINT crTransparent
);

Parameters
hdcDest
Handle to the destination device context.
nXOriginDest
Specifies the x-coordinate, in logical units, of the upper-left corner of the destination rectangle.
nYOriginDest
Specifies the y-coordinate, in logical units, of the upper-left corner of the destination rectangle.
nWidthDest
Specifies the width, in logical units, of the destination rectangle.
hHeightDest
Handle to the height, in logical units, of the destination rectangle.
hdcSrc
Handle to the source device context.
nXOriginSrc
Specifies the x-coordinate, in logical units, of the source rectangle.
nYOriginSrc
Specifies the y-coordinate, in logical units, of the source rectangle.
nWidthSrc
Specifies the width, in logical units, of the source rectangle.
nHeightSrc
Specifies the height, in logical units, of the source rectangle.
crTransparent
The RGB color in the source bitmap to treat as transparent.
Return Values
If the function succeeds, the return value is TRUE.

If the function fails, the return value is FALSE.

内存绘图可以使用DIB，用SetDIBBits画，很快。拖动如果用异或就简单了。
如果不是，可以将窗口背景保存为位图，每拖动一次，就将背景重画一次，速度完全够用。

给我点游戏代码好吗

[sizhi]

嘿嘿,这网站上就有啊,还打着灯笼四处找光.

如果没有的话,我光盘里多的是.
给我你的E-mail就ok了.

我有一个DIB类，呵呵。只有1、透明位图的显示；2、内存绘图的代码；涉及GDI函数：BitBlt、MaskBlt 、TransBitBlt()、、、、

好像有拖拉机的源程序
