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)

repositories { mavenCentral() }

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

dependencies { implementation 'jp.wasabeef.transformers:coil:1.0.6' // Use the GPU Filters  implementation 'jp.wasabeef.transformers:coil-gpu:1.0.6' }

imageView.load(IMAGE_URL) { transformations( CropCenterTransformation(), RoundedCornersTransformation(radius = 120, cornerType = CornerType.DIAGONAL_FROM_TOP_LEFT) ) }

dependencies { implementation 'jp.wasabeef.transformers:glide:1.0.6' // Use the GPU Filters  implementation 'jp.wasabeef.transformers:glide-gpu:1.0.6' }

Glide.with(context) .load(IMAGE_URL) .apply( bitmapTransform( MultiTransformation( CropCenterTransformation(), BlurTransformation(context, 15, sampling = 1) ) ) ).into(imageView)

dependencies { implementation 'jp.wasabeef.transformers:picasso:1.0.6' // Use the GPU Filters  implementation 'jp.wasabeef.transformers:picasso-gpu:1.0.6' }

Picasso.get() .load(IMAGE_URL) .fit().centerInside() .transform( mutableListOf( CropCenterTransformation(), BlurTransformation(context, 25, sampling = 4) ) ).into(imageView)

dependencies { implementation 'jp.wasabeef.transformers:fresco:1.0.6' // Use the GPU Filters  implementation 'jp.wasabeef.transformers:fresco-gpu:1.0.6' }

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) ) )
