Examples

This example uses a SkewTransform to skew text. A skew, also known as a shear, is a transformation that stretches the coordinate space in a non-uniform manner. In this example, the two text strings are skewed -30 degrees and 30 degrees along the x-coordinate.

<Canvas Margin="30">
    <!-- Skew the text using a SkewTransform. -->
    <TextBlock FontSize="32"
               FontWeight="Bold" 
               Foreground="Maroon"
               Text="Skewed Text">
        <TextBlock.RenderTransform>
            <SkewTransform AngleX="-30" AngleY="0" />
        </TextBlock.RenderTransform>
    </TextBlock>

    <TextBlock Canvas.Top="60"
               FontSize="32"
               FontWeight="Bold" 
               Foreground="Maroon"
               Text="Skewed Text">
        <TextBlock.RenderTransform>
            <SkewTransform AngleX="30" AngleY="0" />
        </TextBlock.RenderTransform>
    </TextBlock>
</Canvas>
<Rectangle PointerPressed="IncreaseSkew"
           Width="50" Height="50" 
           Fill="RoyalBlue">
    <Rectangle.RenderTransform>
        <!-- If you give the transform a name 
             you can access it easily from code. -->
        <SkewTransform x:Name="mySkewTransform" />
    </Rectangle.RenderTransform>
</Rectangle>

    mySkewTransform.AngleX = mySkewTransform.AngleX + 5;
}

Inverse Inverse Inverse

Gets the inverse transformation of this GeneralTransform, if possible.

(Inherited from GeneralTransform)

InverseCore InverseCore InverseCore

Implements the behavior for return value of Inverse in a derived or custom GeneralTransform.
