Here is a gist with working BorderedCircleTransform implemenetation:

Unable to apply on SandboxView instead of image?

I am sorry if this is trivial, but I am a beginner. and currently I am using Kotlin. I want to blur my image after downloading using picasso.

and here is the code I use:

Picasso.get()
           .load(currentEvent.posterDownloadPath)
           .transform(BlurTransformation(25,3))
           .into(recommendedEventViewHolder.blurryImageView)

but unfortunately I have error like in this image: https://i.stack.imgur.com/Nvq53.png

so how to properly use BlurTransformation effect ?

hi,

Thanks for your awesome library.
But I have problems with integrate the lib into my app.
I tried to put this line
compile 'jp.wasabeef:picasso-transformations:2.1.0'

but nothing is downloaded. Can you give me some helps?
Thanks

CropCircleTransformation has no parameters, several instances are useless.
This class may provide a static getInstance() method and return the same instance every time, and thus public constructor should be deprecated.

RSBlur creates 4 Objects(2 Allocation, RenderScript and ScriptIntrinsicBlur) but it only destroys the RenderScript. This causes the resources to stick around and never get released. Calling destroy on all of those object in the finally clause fixes the issue.

I will try to find the time to make a PR.

Tested on a Nexus 6

is it possible to add effect to bitmap ?

Dear wasabeef,

I have some feature request.
I need to clean specific color and change it to transparent.
Could it be possible to implement new feature or any suggestion that I can modify your class?

I want to remain only radar stuff and change background and seashore lines to transparent..
So

change this

to this

I just want to set cleaned image to the overlay of google maps

Many Thanks for your great work!!

It would be nice if the POM included the gpuimage-library dependency, so that it will be downloaded automatically with picasso-transformations and we don't have to add that additional dependency to our projects.

already add renderscript in build.gradle:

 defaultConfig {
        applicationId "xxx"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        renderscriptSupportModeEnabled true
    }

when i build the project:

    Path in archive: lib/armeabi-v7a/libblasV8.so
Error:duplicate files during packaging of APK /Users/rowandjj/AndroidStudioProjects/PaimaiNews/app/build/outputs/apk/app-debug-unaligned.apk

so i exclude those .so file by packingOptions:

    packagingOptions{
        exclude 'lib/armeabi-v7a/libblasV8.so'
        exclude 'lib/armeabi-v7a/librsjni.so'
        exclude 'lib/armeabi-v7a/libRSSupport.so'
        exclude 'lib/mips/libblasV8.so'
        exclude 'lib/mips/librsjni.so'
        exclude 'lib/mips/libRSSupport.so'
        exclude 'lib/x86/libblasV8.so'
        exclude 'lib/x86/librsjni.so'
        exclude 'lib/x86/libRSSupport.so'
    }

but it not worked either.....

what should i do?

KuwaharaFilterTransformation turns the transparent part black.
I still want to leave it transparent or change it to white

Is there any way?

I tried excluding the lib from packaging options as suggested by the compiler, but it didn't work. That could be a problem on my end. I'll be going with another library in any case. I also tried

the blur effect is not blurry enough, how can i adjust the amount of blur?

Whenever I apply BlurTransformation with 10px or any px value for that matter. The image just becomes invisible. Anyone got a solution for this?

I can't recognize what is going wrong please help.
My code :

`Picasso.with(PlayScreenActivity.this)
                    .load(uri)
                    .transform(new BlurTransformation(this,25,10))
                    .placeholder(R.drawable.ic_default)
                    .error(R.drawable.ic_default)
                    .into(new Target() {
                        @Override
                        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                        }

                        @Override
                        public void onBitmapFailed(Drawable errorDrawable) {
                        }

                        @Override
                        public void onPrepareLoad(Drawable placeHolderDrawable) {
                        }
                    });`

Hello,

Thanks for the library , this was what i needed!

It always go in onPrepareLoad and then onBitmapFailed! and errorDrawable is null.

Picasso.with(CameraActivity.this).load(filename)
.transform(new SwirlFilterTransformation(CameraActivity.this)).into(new Target() {
@OverRide
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
imageView.setImageBitmap(bitmap);
bmp = bitmap;
}

                @Override
                public void onBitmapFailed(Drawable errorDrawable) {

                }

                @Override
                public void onPrepareLoad(Drawable placeHolderDrawable) {

                }
            });

Hey,

Very nice lib but is there a way to also transform the error and the placeholder image?

I believe it's not necessary to create squaredBitmap. Instead, the BitmapShader can be given a Matrix that has setTranslate(-width, -height). This should accomplish the same thing that creating squaredBitmap does, shifting the viewport on source so that its centre is drawn into bitmap.

CropCenter isn't doing what I expect in the example app. The demo.jpg is 640x359 and the CropCenter example crops it to 300x100 center - I would expect the resulting image to just about cover the dogs' heads but it seems to be full width as you can see the red stripe on the far left of the first dog and the wicker basket on the shelf on the right?

What I expect it to look like:
