## Methods

- [Dilate](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/dilate.md): Apply a dilation (or scaling) transformation to this shader.
- [Flip](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/flip.md): (2 overloads) Repeat and flip a value within a [0, limit] domain.
- [Rotate](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/rotate.md): Apply a rotation transformation to this shader.
- [Transform](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/transform.md): Apply a custom transformation to this shader.
- [Translate](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/translate.md): Apply a translation transformation to this shader.
- [ValueAt](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/valueat.md): Evaluate this shader at a specific ray location.

## Convertors

- [operator implicit](https://developer.rhino3d.com/api/gh2/type/grasshopper2.imaging.raycasting.valueshader/op-implicit.md): (static) Create a constant value shader.
