通过设置Image控件Stretch属性的值可以控制图片的显示形式:
包含的值:None、Fill、Uniform、UniformToFill
1 <Grid x:Name="LayoutRoot" Background="White" Height="489" Width="603">
2 <Image Height="150" HorizontalAlignment="Left" Name="image1" Stretch="None" VerticalAlignment="Top" Width="200" Source="/SilverlightApplication1;component/Images/2009011911345229.jpg" Margin="10,14,0,0" />
3 <Image Height="150" HorizontalAlignment="Left" Margin="325,14,0,0" Name="image2" Stretch="Fill" VerticalAlignment="Top" Width="200" Source="/SilverlightApplication1;component/Images/2009011911345229.jpg" Grid.ColumnSpan="3" />
4 <Image Height="150" HorizontalAlignment="Left" Margin="10,239,0,0" Name="image3" Stretch="Uniform" VerticalAlignment="Top" Width="200" Source="/SilverlightApplication1;component/Images/2009011911345229.jpg" />
5 <Image Height="150" HorizontalAlignment="Left" Margin="325,239,0,0" Name="image4" Stretch="UniformToFill" VerticalAlignment="Top" Width="200" Source="/SilverlightApplication1;component/Images/2009011911345229.jpg" Grid.ColumnSpan="3" />
6 <TextBlock Height="67" HorizontalAlignment="Left" Margin="12,166,0,0" Name="textBlock1" VerticalAlignment="Top" Width="207" TextWrapping="Wrap">
7 <TextBlock.Text>
8 None:图片直接加载到Image控件中,不进行拉伸,如果Image控件的大小是100X100 而图片的大小为1000X1000 则只显示顶部的100X100
9 </TextBlock.Text>
10 </TextBlock>
11 <TextBlock Height="67" HorizontalAlignment="Left" Margin="325,166,0,0" Name="textBlock2" VerticalAlignment="Top" Width="200" TextWrapping="Wrap" Grid.ColumnSpan="3">
12 <TextBlock.Text>
13 Fill:图片会拉伸或缩小以适应Image控件 长宽比可能改变
14 </TextBlock.Text>
15 </TextBlock>
16 <TextBlock Height="67" HorizontalAlignment="Left" Margin="12,395,0,0" Name="textBlock3" TextWrapping="Wrap" VerticalAlignment="Top" Width="200" >
17 <TextBlock.Text>
18 Uniform:图片会拉伸到最佳大小(不一定充满整个Image控件)保持长宽比不变
19 </TextBlock.Text>
20 </TextBlock>
21 <TextBlock Height="67" HorizontalAlignment="Left" Margin="325,395,0,0" Name="textBlock4" VerticalAlignment="Top" Width="200" TextWrapping="Wrap" Grid.ColumnSpan="3">
22 UniformToFill:图片会在不改变长宽比的前提下拉伸,它会充满整个Image控件 但可能被裁减
