# TextureResource.Semantic.scalar

Use the texture to store a single value in each pixel.

## Declaration

```swift
case scalar
```

## Discussion

Discussion Properties that specify a semantic of scalar use the texture to store a single floating point value in each pixel. If the texture’s source is an RGB image, the property uses only the red channel value.
