# init(axis_mask:function:i_desc:o_desc:scale:bias:)

Returns a new quantization layer parameters structure using the supplied parameters.

## Declaration

```swift
init(axis_mask: Int, function: BNNSQuantizerFunction, i_desc: BNNSNDArrayDescriptor, o_desc: BNNSNDArrayDescriptor, scale: BNNSNDArrayDescriptor, bias: BNNSNDArrayDescriptor)
```

## Parameters

- `axis_mask`: A bitmask that defines the axis to which the function applies scale and bias. Set to 0 to apply scale and bias to the entire tensor.
- `function`: The quantize function.
- `i_desc`: The descriptor of the input.
- `o_desc`: The descriptor of the output.
- `scale`: The descriptor of the scale.
- `bias`: The descriptor of the bias.
