What is ScaleTransform good for?

why I should use ScaleX="2" for example instead of double the width of my control ??

<Button Width = "100" Content="Button1"/>


<Button Width = "50" Content="Button2">
   <Button.RenderTransform>
      <ScaleTransform ScaleX="2" />
   </Button.RenderTransform>
</Button>

both buttons look exactly the same so again, what scale is good for

Solution

  • What if it was more complicated than a Button with a Width? What if you had a complex Path/Geometry, or maybe even a group of controls? You wouldn't want to go and manually change everything. What if you had a custom control, where you wanted to give one instance the size 100x100, and another instance 150x150? What if you were implementing zoom functionality (think google maps)?

    In short, for your specific example, it doesn't provide much use. But there are many other cases where it does.
