Crop a bitmap to circle in Android

CropBitmapToCircle.java

public static Bitmap getCircledBitmap(Bitmap bitmap) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2, bitmap.getWidth() / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);

    return output;
}

Works out of the box, thanks man!

Thanks man)) Works great!

Kotlin

    /**
     * Convert square bitmap to circle
     * @param Bitmap - square bitmap
     * @return circle bitmap
     */
    fun Bitmap.getCircledBitmap(): Bitmap {
        val output = Bitmap.createBitmap(this.width, this.height, Bitmap.Config.ARGB_8888)
        val canvas = Canvas(output)
        val paint = Paint()
        val rect = Rect(0, 0, this.width, this.height)
        paint.isAntiAlias = true
        canvas.drawARGB(0, 0, 0, 0)
        canvas.drawCircle(this.width / 2f, this.height / 2f, this.width / 2f, paint)
        paint.xfermode = PorterDuffXfermode(PorterDuff.Mode.SRC_IN)
        canvas.drawBitmap(this, rect, rect, paint)
        return output
    }

It works fine, you saved my project, thank you!

Thanks man, it works great.
