compose-image-blurhash [![](https://jitpack.io/v/orlando-dev-code/compose-image-blurhash.svg)](https://jitpack.io/#orlando-dev-code/compose-image-blurhash) 2 | 3 | ComposeImageBlurhash is a Jetpack Compose component with the necessary implementation to display a blurred image while the real image is loaded from the internet. 4 | Use blurhash and coil to ensure good performance. 5 | 6 | 7 | 8 | ## Coil 9 | The Coil library is used to load the images asynchronously 10 | 11 | You can find more information here [github](https://github.com/coil-kt/coil)! 12 | 13 | ## More from Blurhash 14 | BlurHash is a compact representation of a placeholder for an image. 15 | 16 | 17 | 18 | You can also see nice examples and try it out yourself at 19 | [blurha.sh](http://blurha.sh/)! 20 | 21 | All blurhash code is here 22 | [github](https://github.com/woltapp/blurhash)! 23 | 24 | ## Users 25 | Who uses ComposeImageBlurhash? : 26 | 27 | Inmersoft - At Immersoft we use ComposeImageBlurhash for a better user experience when loading and displaying images to the end user. 28 | 29 | #How to use 30 | 31 | - In the AndroidManifest add the permissions to use the Internet 32 | 33 | 34 | 35 | - In the build.gradle add the necessary dependencies 36 | 37 | implementation 'com.github.orlando-dev-code:compose-image-blurhash:2.1.0' 38 | 39 | - Add component as required 40 | ``` 41 | class MainActivity :
