An Android transformation library providing a variety of image transformations for Coil, Glide, Picasso, and Fresco.

Glide Transformations, Picasso Transformations, Fresco Processors are deprecated.
Development will stop soon.. For an up-to-date version, please use this.

• Android 5.0+ Lollipop (API level 21)

  mavenCentral()
}

This Transformer is NOT using android.support.v8.rendererscript because librs.so make the APK file too big.

val request: ImageRequest =
  ImageRequestBuilder.newBuilderWithSource(IMAGE_URL.toUri())
  .setPostprocessor(BlurPostprocessor(context, 25, 4))
  .build()

holder.image.controller = Fresco.newDraweeControllerBuilder()
  .setImageRequest(request)
  .setOldController(draweeView.controller)
  .build()

Use Composable Images when using with Jetpack Compose.

GlideImage(
  model = IMAGE_URL,
  modifier = Modifier.preferredWidth(120.dp),
  options = RequestOptions().transform(
    BlurTransformation(context, radius = 25, sampling = 4)
  )
)
