This method is intended for use with both render-target and depth stencil surfaces because they must be created multisampled to be used together.
The following C# code fragment demonstrates the use of CheckDeviceMultiSampleType to test for devices that support a specific multisampling method.
[C#]
public void Test_Manager_CheckDeviceMultiSampleType()
{
int result;
// Test some formats
IsDeviceMultiSampleOK(DepthFormat.D16, Format.A8R8G8B8, MultiSampleType.TwoSamples, out result);
if (result != (int)ResultCode.Success)
System.Windows.Forms.MessageBox.Show(String.Format("The multisample options are invalid: {0}", result));
}
public bool IsDeviceMultiSampleOK (DepthFormat depthFmt, Format backbufferFmt, MultiSampleType multisampleType, out int result)
{
AdapterInformation ai = Manager.Adapters.Default;
int qualityLevels = 0;
// Verify that the render target surface supports the given multisample type
if (Manager.CheckDeviceMultiSampleType(ai.Adapter, DeviceType.Hardware, backbufferFmt, false, multisampleType, out result, ref qualityLevels))
{
// Verify that the depth stencil surface supports the given multisample type
if (Manager.CheckDeviceMultiSampleType(ai.Adapter, DeviceType.Hardware, (Format)depthFmt, false, multisampleType, out result, ref qualityLevels))
{
return true; // if both calls succeed
}
}
return false; // if either call fails. NOTE: HRESULT passed back in result
}
The preceding code returns true if the device supports the full-screen MultiSampleType.TwoSamples multisampling method with the surface format.
