首先需要在项目中添加DevExpress组件的引用,然后在XAML中添加ImageEdit控件。
```
<Window x:Class="WpfImageEdit.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"
Title="MainWindow" Height="450" Width="800">
<Grid>
<dxe:ImageEdit Name="imageEdit" />
</Grid>
</Window>
```
接下来,在代码中添加放大和缩小功能的实现。可以通过设置ImageEdit控件的ZoomFactor属性来实现图片的放大和缩小。
```
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void btnZoomIn_Click(object sender, RoutedEventArgs e)
{
imageEdit.ZoomFactor += 0.1;
}
private void btnZoomOut_Click(object sender, RoutedEventArgs e)
{
imageEdit.ZoomFactor -= 0.1;
}
}
```
在XAML中添加两个Button按钮,分别用于触发放大和缩小功能。
```
<Window x:Class="WpfImageEdit.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"
Title="MainWindow" Height="450" Width="800">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Grid.Row="0">
<Button Name="btnZoomIn" Content="放大" Click="btnZoomIn_Click" />
<Button Name="btnZoomOut" Content="缩小" Click="btnZoomOut_Click" />
</StackPanel>
<dxe:ImageEdit Name="imageEdit" Grid.Row="1" />
</Grid>
</Window>
```
这样就完成了一个简单的图片编辑器,可以通过放大和缩小功能来调整图片的大小。
