Attenzione

BitmapEffects are deprecated and no longer function. Consider using Effects where appropriate instead.

Inizializza un handle IMILBitmapEffect ottenuto da CreateBitmapEffectOuter() con l'interfaccia IMILBitmapEffectPrimitive specificata.

Esempio

Nell'esempio seguente viene illustrata un'implementazione di CreateUnmanagedEffect che usa il InitializeBitmapEffect metodo per inizializzare l'oggetto wrapper con l'effetto personalizzato.

unsafe protected override SafeHandle CreateUnmanagedEffect()
{
    const uint CLSCTX_INPROC_SERVER = 1;
    Guid IID_IUnknown = new Guid("00000000-0000-0000-C000-000000000046");
    Guid guidEffectCLSID = new Guid("84CF07CC-34C4-460f-B435-3184F5F2FF2A");
    SafeHandle wrapper = BitmapEffect.CreateBitmapEffectOuter();

    COMSafeHandle unmanagedEffect;
    uint hresult = Ole32Methods.CoCreateInstance(
                        ref guidEffectCLSID,
                        wrapper.DangerousGetHandle(),
                        CLSCTX_INPROC_SERVER,
                        ref IID_IUnknown,
                        out unmanagedEffect);
    InitializeBitmapEffect(wrapper, unmanagedEffect);
    if (0 == hresult) return wrapper;
    throw new Exception("Cannot instantiate effect. HRESULT = " + hresult.ToString());
}

<SecurityPermissionAttribute(SecurityAction.Demand, Flags := SecurityPermissionFlag.UnmanagedCode)>
Protected Overrides Function CreateUnmanagedEffect() As SafeHandle
    Const CLSCTX_INPROC_SERVER As UInteger = 1
    Dim IID_IUnknown As New Guid("00000000-0000-0000-C000-000000000046")
    Dim guidEffectCLSID As New Guid("84CF07CC-34C4-460f-B435-3184F5F2FF2A")
    Dim wrapper As SafeHandle = BitmapEffect.CreateBitmapEffectOuter()

    Dim unmanagedEffect As COMSafeHandle
    Dim hresult As UInteger = Ole32Methods.CoCreateInstance(guidEffectCLSID, wrapper.DangerousGetHandle(), CLSCTX_INPROC_SERVER, IID_IUnknown, unmanagedEffect)
    InitializeBitmapEffect(wrapper, unmanagedEffect)
    If 0 = hresult Then
        Return wrapper
    End If
    Throw New Exception("Cannot instantiate effect. HRESULT = " & hresult.ToString())
End Function
