如何使用SharpDX离线将着色器应用于Bitmap

Question

我想使用sharpdx将着色器应用于位图（离线处理）。我在SharpDX主页上找到了一个样本，可以通过离线处理将效果应用于图像。现在我想将shader.fx应用于它，但我不知道该怎么做。 谁能帮我吗？

以下是代码片段：

# This one will fail
$usfd = [System.IO.IsolatedStorage.IsolatedStorageFile]::GetUserStoreForDomain()

# Inspect the current AppDomain's Evidence
[threading.thread]::GetDomain().Evidence


# Modify the current AppDomain's Evidence
$evidence = new-object System.Security.Policy.Evidence
$zone = new-object System.Security.Policy.Zone('MyComputer')
$evidence.AddHost($zone)
$currentAppDomain = [threading.thread]::GetDomain()
$securityIdentityField=$currentAppDomain.GetType().GetField('_SecurityIdentity','Instance,NonPublic')
$securityIdentityField.SetValue($currentAppDomain, $evidence)

# Inspect the current AppDomain's Evidence
[threading.thread]::GetDomain().Evidence

# This one will succeed
$usfd = [System.IO.IsolatedStorage.IsolatedStorageFile]::GetUserStoreForDomain()

以下是shader.fx

// Effect 1 : BitmapSource - take decoded image data and get a BitmapSource from it
    var bitmapSourceEffect = new d2.Effects.BitmapSource(d2dContext);
    bitmapSourceEffect.WicBitmapSource = formatConverter;


    // Effect 2 : GaussianBlur - give the bitmapsource a gaussian blurred effect
    var gaussianBlurEffect = new d2.Effects.GaussianBlur(d2dContext);
    gaussianBlurEffect.SetInput(0, bitmapSourceEffect.Output, true);
    gaussianBlurEffect.StandardDeviation = 5f;

    d2dContext.BeginDraw();
    d2dContext.DrawImage(gaussianBlurEffect);
    d2dContext.EndDraw();
