问题描述
我有以下 xaml.
<ScrollViewer HorizontalAlignment="Stretch" Margin="107,0,0,0" Name="scrollViewer1" VerticalAlignment="Stretch" HorizontalScrollBarVisibility="Visible">
<Image Name="image1" Stretch="None" MouseWheel="image1_MouseWheel" RenderTransformOrigin="0,0">
</Image>
</ScrollViewer>
后面的代码.
// initialise.
private TransformGroup group = new TransformGroup();
private ScaleTransform st = new ScaleTransform();
group.Children.Add(st);
image1.RenderTransform = group
// mouse event.
TransformGroup group = (TransformGroup)image1.RenderTransform;
ScaleTransform scale = (ScaleTransform)group.Children.Last();
double zoom = e.Delta > 0 ? .2 : -.2;
scale.ScaleX += zoom;
scale.ScaleY += zoom;
如何让滚动条考虑到图像现在的大小不同.滚动条的大小保持不变，我不知道如何更改它们.
How do I get the scroller to take into account that the image is now a different size.The scroll bars remain the same size, and I cannot work out how to change them.
谢谢
推荐答案
您需要 Silverlight Toolkit.不要在图像上设置 RenderTransform，而是将其放在 LayoutTransformer 中.
You need the LayoutTransformer from the Silverlight Toolkit. Instead of setting a RenderTransform on your Image, put it inside a LayoutTransformer.
