上一篇里，已经知道了“伪3D”是怎么回事，今天结合以前的做的图片广告轮换，又弄了一个图片切换的小东东，不知道以后有什么用，先贴在这里备份：
效果图：
因为silverlight的xml读取策略等其它原因，没办法直接在博客中贴出来，下面是在线示例地址：

思路：
1.将每个图片以及下面的标题文字，封装成控件
1
<UserControl x:Class="ControlTest.model.ImgItem"
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
5 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
6 mc:Ignorable="d" >
7
8 <UserControl.Resources>
9 <Storyboard x:Name="sbShow">
10 <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="img" Storyboard.TargetProperty="(UIElement.Opacity)">
11 <EasingDoubleKeyFrame KeyTime="00:00:00" Value="0.0"/>
12 <EasingDoubleKeyFrame KeyTime="00:00:01" Value="1.0"/>
13 </DoubleAnimationUsingKeyFrames>
14 </Storyboard>
15 </UserControl.Resources>
16
17 <StackPanel Orientation="Vertical">
18 <Image x:Name="img" Width="300" Cursor="Hand" Grid.Row="0">
19 <Image.Projection>
20 <PlaneProjection RotationY="60" RotationZ="4" x:Name="pp"></PlaneProjection>
21 </Image.Projection>
22 </Image>
23
24 <TextBlock x:Name="txtTitle" Text="Image's Title" TextAlignment="Center" TextWrapping="Wrap" Grid.Row="0" Visibility="Collapsed" HorizontalAlignment="Center" Margin="0,5,0,0">
25 </TextBlock>
26 </StackPanel>
27
28</UserControl>
<UserControl x:Class="ControlTest.model.ImgItem"2
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"3
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"4
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"5
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"6
mc:Ignorable="d" >7

<UserControl.Resources>9
<Storyboard x:Name="sbShow">10
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="img" Storyboard.TargetProperty="(UIElement.Opacity)">11
<EasingDoubleKeyFrame KeyTime="00:00:00" Value="0.0"/>12
<EasingDoubleKeyFrame KeyTime="00:00:01" Value="1.0"/>13

<StackPanel Orientation="Vertical">18
<Image x:Name="img" Width="300" Cursor="Hand" Grid.Row="0">19
<Image.Projection>20
<PlaneProjection RotationY="60" RotationZ="4" x:Name="pp"></PlaneProjection>21
</Image.Projection>22
</Image>23
24
<TextBlock x:Name="txtTitle" Text="Image's Title" TextAlignment="Center" TextWrapping="Wrap" Grid.Row="0" Visibility="Collapsed" HorizontalAlignment="Center" Margin="0,5,0,0">25
</TextBlock>26
</StackPanel>27
28
</UserControl>2.动态加载xml数据源,xml配置如下:
1<?xml version="1.0" encoding="utf-8" ?>
2<data>
3 <item src="img/001.jpg" title="第一张图片(点击将跳转到百度)" link="http://www.baidu.com/" />
4 <item src="img/002.jpg" title="第二张图片" link="img/002.jpg" />
5 <item src="img/003.jpg" title="第三张图片(点击将跳转到我的博客)" link="http://yjmyzz.cnblogs.com/" />
6 <item src="img/004.jpg" title="第四张图片" link="img/004.jpg" />
7 <item src="img/005.jpg" title="第五张图片" link="img/005.jpg" />
8 <item src="img/006.jpg" title="第六张图片" link="img/006.jpg" />
9 <item src="img/007.jpg" title="第七张图片" link="img/007.jpg" />
10 <item src="img/008.jpg" title="第八张图片" link="img/008.jpg" />
11 <item src="img/009.jpg" title="第九张图片" link="img/009.jpg" />
12 <config canvasleft="150" smallImgTop="100" smallImgWidth="240" bigImgTop="10" bigImgWidth="500" itemSpace="80" midIndex="4" adjustWidth="70"/>
13</data>
14
<?xml version="1.0" encoding="utf-8" ?>2
<data>3
<item src="img/001.jpg" title="第一张图片(点击将跳转到百度)" link="http://www.baidu.com/" />4
<item src="img/002.jpg" title="第二张图片" link="img/002.jpg" />5
<item src="img/003.jpg" title="第三张图片(点击将跳转到我的博客)" link="http://yjmyzz.cnblogs.com/" />6
<item src="img/004.jpg" title="第四张图片" link="img/004.jpg" />7
<item src="img/005.jpg" title="第五张图片" link="img/005.jpg" />8
<item src="img/006.jpg" title="第六张图片" link="img/006.jpg" />9
<item src="img/007.jpg" title="第七张图片" link="img/007.jpg" />10
<item src="img/008.jpg" title="第八张图片" link="img/008.jpg" />11
<item src="img/009.jpg" title="第九张图片" link="img/009.jpg" />12
<config canvasleft="150" smallImgTop="100" smallImgWidth="240" bigImgTop="10" bigImgWidth="500" itemSpace="80" midIndex="4" adjustWidth="70"/>13
</data>14
3.动态生成1中封装的控件，然后动态加载到主界面中的Canvas 中
详情见源代码
仍有很多改进之外，比如图片太多时，横向可考虑用左右箭头移动，而且现在这种直接渐变出大图的效果也很粗糙，如果有朋友抽空改进了，记得通知我一起分享(目前国内的silverlight研究氛围太淡，需要更多人的关注...)
