Remarks

A SkewTransform is useful for creating the illusion of three-dimensional depth in a two-dimensional object.

The local origin 0,0 for an object can be offset on a Canvas using Canvas.Left and Canvas.Top, but this does not count as a transform; the object retains its own local 0,0 in this case for transformation purposes.

Multiple transforms can be applied with a TransformGroup. Custom transforms can be created with a MatrixTransform.

The following illustration shows three examples of a SkewTransform applied to a Rectangle.

TextBlock using a SkewTransform

Different AngleX, AngleY, and Center values.

Transforms can alter the display of text in your application to create a decorative effect. The following illustration shows text skewed along the x-axis.

Text skewed along the x-axis

Skewed text.

NoteNote:

A typeface can simulate an italic style by shearing, or skewing, a glyph. However, a non-simulated italic typeface is typically designed to have a better visual appearance than a simulated italic typeface.

Examples

The following 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.

Run this sample

The example below shows how to increase the AngleX property value of a SkewTransform applied to a Rectangle every time the Rectangle is clicked.

Run this sample

    <Rectangle MouseLeftButtonDown="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>
