Viewbox, WPF. A Viewbox resizes the control nested within it. With its Stretch attribute, we resize the element to fill the entire Viewbox.
Getting started. Please drag a Viewbox to your Window—it will be nested within the default Grid. Now adjust its properties. Add a Stretch attribute.

Example. Here we adjust a Viewbox and its XAML. In the screenshot, the Stretch attribute is set to "Fill." So the text in the TextBox becomes distorted.
Tip Using "Fill" will not look good: it may also lead to blurring or other pixel artifacts.

Tip 2 When using a Viewbox, I recommend trying all the Stretch options to find the best one for your purpose.
<Window x:Class="WpfApplication10.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <Viewbox HorizontalAlignment="Left" Height="299" Margin="10,10,0,0" VerticalAlignment="Top" Width="497" Stretch="Fill"> <TextBox Height="23" TextWrapping="Wrap" Text="TextBox" Width="120"/> </Viewbox> </Grid> </Window>
RenderTransform. A Viewbox is not the only way to scale and transform a control. You can add a RenderTransform element inside your control to specify how it is rendered.
Tip RenderTransform element can apply skew, scale, rotate and translate transformations.

Note, simple effects. The Viewbox is great for simple stuff. A DoubleAnimation element (along with a Storyboard) can be used for animating things.

WPF has strong support for transforming how elements, including controls, pictures and text, are rendered. And Viewbox is another way we exploit these capabilities.
