将动态创建的位图对象绑定到 WPF 中的图像
我有一个不是静态资源的位图对象。通常，通过 WPF 中的图像绑定，您可以绑定到字符串路径。但是，我有一个动态创建的位图对象，我想绑定到该对象。是否可以执行类似的操作：
<WrapPanel x:Name="imageWrapPanel" HorizontalAlignment="Center">
<Image Source="{Binding Material1}" Margin="10" />
<Image Source="/NightVision;component/Images/concrete_texture.tif" Margin="10" />
</WrapPanel>
在文件后面的代码中，我有一个公共访问器：
public Bitmap Material1 {
get
{
return new Bitmap(/* assume created somewhere else*/)
}
}
上面的内容显然不起作用，但是，有没有办法执行类似的操作？
I have a bitmap object that is not a static resource. Normally, with image binding in WPF you can bind to a string path. However, I have a dynamically created bitmap object that I would like to bind to. Is it possible to do something like:
<WrapPanel x:Name="imageWrapPanel" HorizontalAlignment="Center">
<Image Source="{Binding Material1}" Margin="10" />
<Image Source="/NightVision;component/Images/concrete_texture.tif" Margin="10" />
</WrapPanel>
And in the code behind file I have a public accessor:
public Bitmap Material1 {
get
{
return new Bitmap(/* assume created somewhere else*/)
}
}
The above is obviously not working however, is there a way to do something similar?

您唯一需要做的就是将
Bitmap转换为可在Image控件中使用的ImageSource。因此，在您的绑定中，您可以添加Converter可以实现这一点。转换的实现可能可以在 的答案中找到这个问题。（如果您有机会直接使用
BitmapImage(WPF) 而不是Bitmap(WinForms)，这可能是个好主意）The only thing you need to do is convert the
Bitmapto anImageSourcewhich can be used in theImagecontrol. So in your binding you can add aConverterwhich accomplishes that. The implementation of the conversion is likely to be found in the answers to this question.(If you have a chance to work directly with
BitmapImage(WPF) instead ofBitmap(WinForms) that might be quite a good idea)
