如何在 C++ 中截取全屏游戏的屏幕截图?我知道它可以用directx 来完成,并且我编写了一个简单的代码,可以截取窗口的屏幕截图,但我不知道如何获得游戏的HWND。这是我的代码。
#include <d3dx9.h>
#include <d3dx9tex.h>
#include <stdio.h>
#pragma comment(lib,"d3d9.lib")
#pragma comment(lib,"d3dx9.lib")
int main()
{
IDirect3DSurface9 *surface;
IDirect3DDevice9 *g_pd3dDevice;
IDirect3D9 *g_pD3D;
D3DDISPLAYMODE d3ddm;
D3DPRESENT_PARAMETERS d3dpp;
HWND hWnd = GetConsoleWindow();
if((g_pD3D = Direct3DCreate9(D3D_SDK_VERSION)) == NULL)
{
printf("fail 1");
}
if(FAILED(g_pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm)))
{
printf("fail 2");
}
ZeroMemory(&d3dpp, sizeof(D3DPRESENT_PARAMETERS));
d3dpp.Windowed = TRUE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.BackBufferFormat = d3ddm.Format;
d3dpp.BackBufferHeight = d3ddm.Height;
d3dpp.BackBufferWidth = d3ddm.Width;
if(FAILED(g_pD3D->CreateDevice(D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL, hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &g_pd3dDevice)))
{
printf("fail 3");
}
g_pd3dDevice->CreateOffscreenPlainSurface(800, 600, D3DFMT_A8R8G8B8, D3DPOOL_SCRATCH, &surface, NULL);
g_pd3dDevice->GetFrontBufferData(0, surface);
D3DXSaveSurfaceToFile("c:\\tmp\\output.jpg", D3DXIFF_JPG, surface, NULL, NULL);
surface->Release();
return 0;
}
