推荐答案

您可以从MSDN查看资源是否有关于此类主题的数据。他们已经有了这些主题的实例，这些主题很有帮助，并且（在他们正在执行的几乎每一行代码中都有注释）解释代码及其在上下文中的用法。



这是代码将图像转换为GreyScale [ ^ ]。



您可以从已存在的图像或运行时创建位图图像。

You can look into resources are data on such topics from MSDN. They've got working example on these topics that are helpfull and have comments (on almost each and every line of code they're executing) that explain the code and its usage in the context.

Here is the code that converts the Image to GreyScale[^].

You create a Bitmap image from an already present Image or on the runtime.

BitmapImage myBitmapImage = new BitmapImage();

您可以为其添加源。你创建一个FormatChangedBitmap对象

You add a source to it. You create a FormatChangedBitmap object as

FormatConvertedBitmap newFormatedBitmapSource = new FormatConvertedBitmap();

将其源代码添加为UI中的Bitmap。然后，您只需更改像素的格式，并将其更改为GrayScale。在上面的文档中，这一行就是这样做的。

Add its source to be the Bitmap you're having from the UI. Then you just change the format of the pixels, and change them to GrayScale. In the above document, this line does it.

newFormatedBitmapSource.DestinationFormat = PixelFormats.Gray32Float;

完成此操作后，您将创建一个新图像，将其源作为此灰度图像添加，然后在UI中显示。像这样，

Once this is done, you create a new Image, add its source as this grayscale-ed image and then show it inside the UI. Like this,

myImage.Source = newFormatedBitmapSource;

现在将其添加到面板（或面板的背景）。

Now add it to a panel (or the panel's background).
