Gets or sets the x-axis scale factor. This is a dependency property.

Values between 0 and 1 decrease the width of the scaled object; values greater than 1 increase the width of the scaled object. A value of 1 indicates that the object is not scaled in the x-direction.
Negative values flip the scaled object horizontally. Values between 0 and -1 flip the scale object and decrease its width. Values less than -1 flip the object and increase its width. A value of -1 flips the scaled object but does not change its horizontal size.

This example shows how to use a ScaleTransform to scale an element.
Use the and ScaleY properties to resize the element by the factor you specify. For example, a value of 1.5 stretches the element to 150 percent of its original width. A ScaleY value of 0.5 shrinks the height of an element by 50 percent.
Use the CenterX and CenterY properties to specify the point that is the center of the scale operation. By default, a ScaleTransform is centered at the point (0,0), which corresponds to the upper-left corner of the rectangle. This has the effect of moving the element and also of making it appear larger, because when you apply a Transform, you change the coordinate space in which the object resides.
<!-- Scales a rectangle by 200% from a center of (0,0).--> <Rectangle Height="50" Width="50" Fill="#CCCCCCFF" Stroke="Blue" StrokeThickness="2" Canvas.Left="100" Canvas.Top="100"> <Rectangle.RenderTransform> <ScaleTransform CenterX="0" CenterY="0" ScaleX="2" ScaleY="2" /> </Rectangle.RenderTransform> </Rectangle>
<!-- Scales a rectangle by 200% from a center of (25,25).--> <Rectangle Height="50" Width="50" Fill="#CCCCCCFF" Canvas.Left="100" Canvas.Top="100" Stroke="Blue" StrokeThickness="2"> <Rectangle.RenderTransform> <ScaleTransform CenterX="25" CenterY="25" ScaleX="2" ScaleY="2" /> </Rectangle.RenderTransform> </Rectangle>
The following illustration shows the difference between the two ScaleTransform operations. The dotted line shows the size and position of the rectangle before scaling.
