[游戏模版7] Win32 最简单贴图

 

>_<:this is the first using mapping.

>_<:There will be introducing how to do:

• First load bitmap picture return handle give hbmp, as following:
• hbmp=(HBITMAP)LoadImage(NULL,"bg.bmp",IMAGE_BITMAP,600,450,LR_LOADFROMFILE);
• there "bg.bmp" must put in the project folder!
• Second if you want draw this picture in the window,I suggest you should create a CompatibleDC, maybe now you don't know why do this, the reason is also hard to explane. You just remember doing is better for showing many pictures reducing Flash.
• hdc=GetDC(hWnd);
• mdc=CreateCompatibleDC(hdc);
• Third when you finish upper two steps, you can use SelectObject(mdc,hbmp); give the picture to CompatibleDC mdc
• Finally just use BitBlt(hdc,0,0,600,450,mdc,0,0,SRCCOPY); copy mdc including to hdc to show in the window.
