# ConvolutionKernel class

Namespace: [Grasshopper2.Imaging.Shaders](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.imaging.shaders.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
public sealed class ConvolutionKernel
```

Represents a custom convolution kernel.

## Properties

- [Height](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/height.md): Gets the full height of the kernel.
- [Inverse](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/inverse.md): Gets the inverse of all cells in the kernel.
- [RadiusX](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/radiusx.md): Gets the radius in the X direction. This is identical to the (Width - 1) / 2.
- [RadiusY](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/radiusy.md): Gets the radius in the Y direction. This is identical to the (Height - 1) / 2.
- [Total](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/total.md): Gets the total weight of all cells in the kernel.
- [Width](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/width.md): Gets the full width of the kernel.

## Indexers

- [this[]](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.shaders.convolutionkernel/item.md): Gets the weight of the specified cell.
