我怎样才能让一个WPF图像disableable？ [英] How can I make a WPF Image disableable?

问题描述

我需要禁用（IsEnabled = FALSE）时显示为灰色图像。图像的灰色显示的版本可以通过读取的BitmapImage成被出示一张FormatConvertedBitmap的这里。

我已经能够得到一个用户控件这方面的工作，但现在的我想同样的行为在一个专门的Image类有更多的灵活性。如果这是在XAML实现我不在乎，代码隐藏或两者兼而有之，但它需要图像的子类

用法可能是：

 < D​​isableableImage源=图像/ image1.png/> 
< D​​isableableImage源=图像/ image1.pngIsEnabled =FALSE/> 
 
<！ - 由于IsEnabled被继承了下来树，
图像将被Like按钮的其余部分变灰 - > 
<按钮IsEnabled =FALSE> 
< StackPanel的方向=横向> 
<&的TextBlock GT;确定< / TextBlock的> 
< D​​isableableImage源=图像/ ok.png/> 
< / StackPanel的> 
< /按钮>

编辑：
或的这个（所有你需要的是AutoGreyableImage类）

I need an Image that is grayed out when disabled (IsEnabled=False). A grayed out version of the image can be produced by reading the BitmapImage into a FormatConvertedBitmap which is shown here.

I have been able to get this working with a UserControl but now I would like the same behavior in a specialized Image class for more flexibility. I don't care if this is implemented in XAML, code-behind or both, but it needs to be a subclass of Image.

The usage could be:

<DisableableImage Source="Images/image1.png" />
<DisableableImage Source="Images/image1.png" IsEnabled="False" />

<!-- Since IsEnabled is inherited down the tree,
     the image will be grayed out like the rest of the button -->
<Button IsEnabled="False">
    <StackPanel Orientation="Horizontal">
        <TextBlock>OK</TextBlock>
        <DisableableImage Source="Images/ok.png" />
    </StackPanel>
</Button>
