WPF change transforms in c#

Question

I tried to change the scale of an Image with

MYIMAGE.RenderTransform.ScaleTransform.ScaleX = 1;

but it didn't work. So my question is how do I change first off the scale but secondly also the Transform methods, or how do I access the different Transformations via code?

Standard caveats around avoiding code-behind apply (though this kind of code can be super useful when dynamically generating animations).

RenderTransform is a property that holds a single object reference. It could be a ScaleTransform, TranlateTransform or even a TransformGroup. It doesn't have a ScaleTransform property. The simple way of handling your code would be to assume you know it's a ScaleTransform:

((ScaleTransform)MYIMAGE.RenderTransform).ScaleX = 1;

If you don't know what the type is then you would need is/as checks. In the case of a transform group you end up with an array. If you know the scale transform is first then this would work:

((ScaleTransform)((TransformGroup)MYIMAGE.RenderTransform).Children[0]).ScaleX = 1;

A more generic/safe implementation is left as an exercise.
