问题：directx截图的问题
描述: 怎么我GetBackBuffer截出来的图是花的
private void button1_Click(object sender, EventArgs e)
{
Microsoft.DirectX.Direct3D.Device myDevice;
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = true;
presentParams.AutoDepthStencilFormat = DepthFormat.D16;
presentParams.SwapEffect = SwapEffect.Discard;
presentParams.PresentFlag = PresentFlag.LockableBackBuffer;
presentParams.BackBufferWidth = 1280;
presentParams.BackBufferHeight = 800;
presentParams.MultiSample = MultiSampleType.None;
presentParams.BackBufferCount = 1;
presentParams.DeviceWindowHandle = this.Handle;
myDevice = new Device(0, DeviceType.Hardware, this, CreateFlags.SoftwareVertexProcessing, presentParams);
Surface mySurface = myDevice.GetBackBuffer(0, 0, Microsoft.DirectX.Direct3D.BackBufferType.Mono);
SurfaceLoader.Save("c:\\Screenshot.bmp", ImageFileFormat.Bmp, mySurface);
Microsoft.DirectX.GraphicsStream gStr = Microsoft.DirectX.Direct3D.SurfaceLoader.SaveToStream(ImageFileFormat.Bmp, mySurface);
pictureBox1.Image = Bitmap.FromStream(gStr);
Bitmap screen = new Bitmap(Bitmap.FromStream(gStr));
gStr.Dispose();
mySurface.Dispose();
}
解决方案1:
PresentParameters pp = new PresentParameters();
pp.Windowed = true;
pp.SwapEffect = SwapEffect.Discard;
Device dv = new Device(0, DeviceType.Hardware, this, CreateFlags.HardwareVertexProcessing, pp);
Surface sf = dv.CreateOffscreenPlainSurface(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, Format.A8R8G8B8, Pool.SystemMemory);
dv.GetFrontBufferData(0, sf);
GraphicsStream gs = SurfaceLoader.SaveToStream(ImageFileFormat.Bmp, sf);
pictureBox1.Image = Bitmap.FromStream(gs);
以上介绍了“directx截图的问题”的问题解答，希望对有需要的网友有所帮助。
