BitmapEffect.InitializeBitmapEffect(SafeHandle, SafeHandle) 方法

定義

警告

此 API 現已淘汰。

使用指定的 IMILBitmapEffectPrimitive,初始化從 CreateBitmapEffectOuter() 獲得的 IMILBitmapEffect 控制代碼。Initializes an IMILBitmapEffect handle obtained from CreateBitmapEffectOuter() with the given IMILBitmapEffectPrimitive.

範例

下列範例示範的CreateUnmanagedEffect執行, 其InitializeBitmapEffect使用方法來初始化具有自訂效果的包裝函式物件。The following example shows an implementation of CreateUnmanagedEffect that uses the InitializeBitmapEffect method to initialize the wrapper object with the custom effect.

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
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
