# GLKTextureLoaderApplyPremultiplication

Whether image data should be premultiplied before being loaded into the sharegroup.

```
let GLKTextureLoaderApplyPremultiplication: String
```

## Discussion

The value for this key is an <doc://com.apple.documentation/documentation/Foundation/NSNumber> object that specifies a boolean value. If <doc://com.apple.documentation/documentation/Swift/false>, the data is loaded into the sharegroup without being modified. If <doc://com.apple.documentation/documentation/Swift/true>, the red, green and blue components of each pixel are multiplied by the alpha value. If the key is not specified, the default value is <doc://com.apple.documentation/documentation/Swift/false>. Never specify <doc://com.apple.documentation/documentation/Swift/true> for a texture that is in a compressed format.
