从UserControl获取图像(预览) [英] Getting Image (Preview) from UserControl

问题描述

大家好.

好吧，这是一个奇怪的问题，但是来了

是否可以在不以用户控件的形式呈现并将其加载到wpf表单的情况下表示有关usercontrol的预览?

用类似这样的代码

在xaml中，我们有预览图像组件

Hi all.

Well this is odd question but here it comes

Is it possible to represent preview about usercontrol without presenting and loaded it on the wpf form as a usercontrol?

in code something like this

in xaml we have preview image component

<Image x:Name="previewImage"></Image>

并在代码背后的某个地方

and somewhere in codebehind

MyUserControl control = new MyUserControl();
//get here image of control and present it as a Source of previewImage component
previewImage.Source = "Here is preview about my usercontrol"

接收到的图像应在运行时内存中处理，而不要保存在硬盘驱动器中.

希望你有主意:)

干杯！

Received image should be handled in runtime memory and not to be saved in hard drive.

Hope you got idea :)

Cheers!

推荐答案

您可以使用您可以添加一个Rectangle(而不是您的Image):

You can add a Rectangle (instead of your Image):

<Rectangle Name="myRect" Stroke="Black" StrokeThickness="2" Margin="5" />

，并使用包含您的控件的VisualBrush设置其Fill:

and, set its Fill with a VisualBrush that contains your control:

MyUserControl control = new MyUserControl();

VisualBrush vb = new VisualBrush
{
    Visual = control,
    Stretch = System.Windows.Media.Stretch.Uniform
};

myRect.Fill = vb;
