# TextureResource.Compression

The compression to apply when importing an image as a texture.

```
struct Compression
```

## Overview

Compression allows varying levels of memory usage gains at the cost of image-quality reduction.

## Topics

### Specifying the compression settings

[`static var `default`: TextureResource.Compression`](/documentation/RealityKit/TextureResource/Compression/default)

A texture you can create and export with lossy compression.

[`static var none: TextureResource.Compression`](/documentation/RealityKit/TextureResource/Compression/none)

A texture you can create with no compression.

[`static func astc(blockSize: TextureResource.Compression.ASTCBlockSize, quality: TextureResource.Compression.ASTCQuality) -> TextureResource.Compression`](/documentation/RealityKit/TextureResource/Compression/astc(blockSize:quality:))

Compresses the imported image with ASTC.

[`enum ASTCBlockSize`](/documentation/RealityKit/TextureResource/Compression/ASTCBlockSize)

The compressed block size.

[`enum ASTCQuality`](/documentation/RealityKit/TextureResource/Compression/ASTCQuality)

Selects the level of processing time allocated to achieve compression.
