Is there a way to apply a scaling transformation to an element in react native that is relative to the window size by a percentage?

One method that can be used to achieve a similar result is by following this formula:

const { width } = useWindowDimension();
const percentage = width * 0.8; // 80% of the window

<ComponentOrElement style={ width: percentage } />

However, this calculation is based on the width (or sometimes the height) of the element. What I actually want is to achieve the same effect but based on scaling transformation. Here's an example:

const { width } = useWindowDimension();
const percentage = width * 0.8; // 80% of the window?

<ComponentOrElement style={ transform: [ { scale: percentage } ] } />

It's worth noting that scaling typically ranges from 0 to 1, representing a factor rather than specific pixels or dp.

Any suggestions on how to apply this scaling?

Answer №1

To maintain the center view while scaling:

const { width } = useWindowDimension();    

<ComponentOrElement style={{ width: width, transform: [{ scaleX: 0.8 }] }} />

Shifting to the right:

const scale = .8;

<ComponentOrElement
  style={{
    width: width,
    transform: [{ translateX: width * (1 - scale) * 0.5 }, { scaleX: scale }],
  }}
/>

Shifting to the left:

<ComponentOrElement
  style={{
    width: width,
    transform: [{ translateX: width * (scale - 1) * 0.5 }, { scaleX: scale }],
  }}
/>

However, these methods may cause distortion in the content.
