WPF用RenderTransform实现，随便做了个，代码如下。

Window x:Class="WpfApplication3.MainWindow"
xmlns="
xmlns:x="
Title="MainWindow"
Height="350"
Width="525"
Grid
Image Name="image" Source="/WpfApplication3;component/Images/Hydrangeas.jpg"
Image.RenderTransform
TransformGroup
RotateTransform x:Name="rt"/
ScaleTransform x:Name="st"/
TranslateTransform x:Name="tt"/
/TransformGroup
/Image.RenderTransform
/Image
StackPanel Orientation="Horizontal"
Height="20"
Button Name="btnScale1"
Content="缩小"
Click="btnScale1_Click" /
Button Name="btnScale2"
Content="放大"
Click="btnScale2_Click" /
Button Name="btnRotation1"
Content="左转"
Click="btnRotation1_Click" /
Button Name="btnRotation2"
Content="右转"
Click="btnRotation2_Click" /
Button Name="btnMove1"
Content="左移"
Click="btnMove1_Click" /
Button Name="btnMove2"
Content="右移"
Click="btnMove2_Click" /
Button Name="btnMove3"
Content="上移"
Click="btnMove3_Click"/
Button Name="btnMove4"
Content="下移"
Click="btnMove4_Click" /
/StackPanel
/Grid
/Window
CS如下
namespace WpfApplication3
{
/// summary
/// MainWindow.xaml 的交互逻辑
/// /summary
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = this;
}
private bool _ischecked = false;
public bool IsChecked
{
get
{
return _ischecked;
}
}
private void btnScale1_Click(object sender, RoutedEventArgs e)
{
st.CenterX = image.ActualWidth / 2;
st.CenterY = image.ActualHeight / 2;
st.ScaleX -= 0.1;
st.ScaleY -= 0.1;
}
private void btnScale2_Click(object sender, RoutedEventArgs e)
{
st.CenterX = image.ActualWidth / 2;
st.CenterY = image.ActualHeight / 2;
st.ScaleX += 0.1;
st.ScaleY += 0.1;
}
private void btnRotation1_Click(object sender, RoutedEventArgs e)
{
rt.CenterX = image.ActualWidth / 2;
rt.CenterY = image.ActualHeight / 2;
rt.Angle -= 10;
}
private void btnRotation2_Click(object sender, RoutedEventArgs e)
{
rt.CenterX = image.ActualWidth / 2;
rt.CenterY = image.ActualHeight / 2;
rt.Angle += 10;
}
private void btnMove1_Click(object sender, RoutedEventArgs e)
{
tt.X -= 10;
}
private void btnMove2_Click(object sender, RoutedEventArgs e)
{
tt.X += 10;
}
private void btnMove3_Click(object sender, RoutedEventArgs e)
{
tt.Y -= 10;
}
private void btnMove4_Click(object sender, RoutedEventArgs e)
{
tt.Y += 10;
}
}
}

Q2: 在html5中插入图片，会出现框，应该是图片的影子，但是图片显示不了。
一般来说是因为你的图片路径没写对，或者是图片不存在，请多检查一次。
Q3: html5中怎么把一张图片放另一张图片上
可以通过css中的position:absolute和relative，并结合z-index调整图片的上下关系
Q4: HTML5图片导入和编辑功能的实现
让用户在画板上拖拽、缩放、多图组合操作的话，需要用到Canvas或者SVG的编程，给元素绑定拖拽等鼠标事件
