# useZoomFactor
|
|
|
|
Reactive [WebFrame](https://www.electronjs.org/docs/api/web-frame#webframe) zoom factor.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useZoomFactor } from '@vueuse/electron'
|
|
|
|
// enable nodeIntegration if you don't provide webFrame explicitly
|
|
// see: https://www.electronjs.org/docs/api/webview-tag#nodeintegration
|
|
// Ref result will return
|
|
const factor = useZoomFactor()
|
|
console.log(factor.value) // print current zoom factor
|
|
factor.value = 2 // change current zoom factor
|
|
```
|
|
|
|
Set initial zoom factor immediately
|
|
|
|
```ts
|
|
import { useZoomFactor } from '@vueuse/electron'
|
|
|
|
const factor = useZoomFactor(2)
|
|
```
|
|
|
|
Pass a `ref` and the factor will be updated when the source ref changes
|
|
|
|
```ts
|
|
import { useZoomFactor } from '@vueuse/electron'
|
|
import { shallowRef } from 'vue'
|
|
|
|
const factor = shallowRef(1)
|
|
|
|
useZoomFactor(factor) // zoom factor will match with the ref
|
|
|
|
factor.value = 2 // zoom factor will change
|
|
```
|
|
|
|
## Type Declarations

|
|
|
```ts
|
|
export declare function useZoomFactor(factor: MaybeRef<number>): Ref<number>
|
|
export declare function useZoomFactor(
|
