# setZoomValue(_:)

Sets the zoom value.

```
func setZoomValue(_ aValue: Float)
```

## Parameters

`aValue`

The zoom value. This value should be greater or equal to zero and less or equal than one. A zoom value of zero corresponds to the minimum size (40x40 pixels). A zoom value of one means images fits the browser bounds. Other values are interpolated.

## Discussion

You must use `setZoomValue` or [`setCellSize(_:)`](/documentation/Quartz/IKImageBrowserView/setCellSize(_:)), but not both. Setting the zoom value changes the cell size, and vice versa.

## See Also

[`func setCellSize(NSSize)`](/documentation/Quartz/IKImageBrowserView/setCellSize(_:))

Sets the cell  size.
