# ResamplingFilter

A pointer to a resampling filter callback function.

## Declaration

```swift
typealias ResamplingFilter = UnsafeMutableRawPointer
```

## Discussion

Discussion You pass a resampling filter callback to a shear function. The resampling filter pointer can point to a structure that contains a function, rows of precalculated values, flag settings, and so on. The shear function requires that the structure contains a scale factor.
