Image transformations for Coil.

Download

Add the library to your app build.gradle:

implementation("com.commit451.coiltransformations:transformations:latest.version.here")

and for GPU (native) transformations (relies on GPUImage):

# Android only
implementation("com.commit451.coiltransformations:transformations-gpu:latest.version.here")

and for Google MLKit Face detection transformations:

# Android only
implementation("com.commit451.coiltransformations:transformations-face-detection:latest.version.here")

Supported Transformations

These transformations are already supported in Coil itself (no need for this library):

• CircleCropTransformation
• RoundedCornersTransformation

From the base library (transformations):

• ColorFilterTransformation
• CropTransformation (top, center, bottom)
• GrayscaleTransformation
• SquareCropTransformation

Android only

• BlurTransformation
• MaskTransformation

From the GPU library (transformations-gpu) Android only

• BrightnessFilterTransformation
• ContrastFilterTransformation
• InvertFilterTransformation
• KuwaharaFilterTransformation
• PixelationFilterTransformation
• SepiaFilterTransformation
• SketchFilterTransformation
• SwirlFilterTransformation
• ToonFilterTransformation
• VignetteFilterTransformation

From the face detection library (transformations-face-detection) Android only

• CenterOnFaceTransformation

Quick Start

To load an image into a Composable with transformations:

AsyncImage(
    model = ImageRequest.Builder(LocalPlatformContext.current)
        .data(imageUrl)
        .transformations(GrayscaleTransformation())
        .crossfade(true)
        .build(),
    contentDescription = sample.name,
    contentScale = ContentScale.Crop,
    modifier = Modifier
        .fillMaxWidth()
        .aspectRatio(1f)
        .clip(RoundedCornerShape(8.dp)),
)
