# MPSImagePyramid

A base class for creating different kinds of pyramid images.

```
class MPSImagePyramid
```

## Topics

### Initializers

[`init(coder:device:)`](/documentation/MetalPerformanceShaders/MPSImagePyramid/init(coder:device:))

### Methods

[`init(device:)`](/documentation/MetalPerformanceShaders/MPSImagePyramid/init(device:))

Initializes a downwards 5-tap image pyramid with the default filter kernel and device.

[`init(device:centerWeight:)`](/documentation/MetalPerformanceShaders/MPSImagePyramid/init(device:centerWeight:))

Initialize a downwards 5-tap image pyramid with a central weight parameter and device.

[`init(device:kernelWidth:kernelHeight:weights:)`](/documentation/MetalPerformanceShaders/MPSImagePyramid/init(device:kernelWidth:kernelHeight:weights:))

Initialize a downwards n-tap image pyramid with a custom filter kernel and device.

### Properties

[`kernelWidth`](/documentation/MetalPerformanceShaders/MPSImagePyramid/kernelWidth)

The width of the filter window. Must be an odd number.

[`kernelHeight`](/documentation/MetalPerformanceShaders/MPSImagePyramid/kernelHeight)

The height of the filter window. Must be an odd number.
