Crop image in circular shape in android

Hello Friends,

Have you searching for cropping an image and convert it into circular shape ???
Following function will helps you to convert an image into circular shape.



Note: I am passing my image in bitmap format as a parameter in a function.

  /*
  * Making image in circular shape
  */
 public Bitmap getRoundedShape(Bitmap scaleBitmapImage) {
  // TODO Auto-generated method stub
  int targetWidth = 50;
  int targetHeight = 50;
  Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, 
                            targetHeight,Bitmap.Config.ARGB_8888);
  
                Canvas canvas = new Canvas(targetBitmap);
  Path path = new Path();
  path.addCircle(((float) targetWidth - 1) / 2,
  ((float) targetHeight - 1) / 2,
  (Math.min(((float) targetWidth), 
                ((float) targetHeight)) / 2),
          Path.Direction.CCW);
  
                canvas.clipPath(path);
  Bitmap sourceBitmap = scaleBitmapImage;
  canvas.drawBitmap(sourceBitmap, 
                                new Rect(0, 0, sourceBitmap.getWidth(),
    sourceBitmap.getHeight()), 
                                new Rect(0, 0, targetWidth,
    targetHeight), null);
  return targetBitmap;
 }


For providing border around your imageView :
   
    <ImageView
            android:id="@+id/imgView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_above="@+id/btnEdit"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="40dp"
            android:background="@drawable/rounded"
            android:adjustViewBounds="true"
            android:gravity="center"
            android:src="@drawable/happy"/>

Add this xml inside your drawable folder :

=>rounded.xml

<?xml version="1.0" encoding="utf-8"?>

    <solid android:color="@android:color/white" />

    <stroke
        android:width="3dip"
        android:color="#FF0000" />

    <corners android:radius="10dp" />
    <padding
        android:bottom="0dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp" />

</shape>



Hope , this will helps anyone......
Enjoy Coding.... :)

  2. I Agreed that image is not clear .Sorry, I just forgot to update my answer.

    Try to use antialiasing and filterbitamp in your code. Try this code....an d let me know its work or not....

    Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight,
    Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(targetBitmap);
    Path path = new Path();
    path.addCircle(((float) targetWidth) / 2,
    ((float) targetHeight) / 2,
    (Math.min(((float) targetWidth), ((float) targetHeight)) / 2),
    Path.Direction.CW);
    Paint paint = new Paint();
    paint.setColor(Color.GRAY);
    //paint.setStyle(Paint.Style.STROKE);
    paint.setStyle(Paint.Style.FILL);
    paint.setAntiAlias(true);
    paint.setDither(true);
    paint.setFilterBitmap(true);
    canvas.drawOval(new RectF(0, 0, targetWidth, targetHeight), paint) ;
    //paint.setColor(Color.TRANSPARENT);
    canvas.clipPath(path);
    Bitmap sourceBitmap = scaleBitmapImage;
    canvas.drawBitmap(sourceBitmap, new Rect(0, 0, sourceBitmap.getWidth(),
    sourceBitmap.getHeight()), new RectF(0, 0, targetWidth,
    targetHeight), paint);

  5. Thanks Gaurav,
    You can add the 3dp round border across your image using "drawable". I am sharing my code in which I am doing the same thing.May be its helps you.....

    rounded.xml:










    And in my layout(xml) where I am using the imageview to show the rounded image with 3 dp border,I just set the backround from drawable.
    See the code:




    Let me know its helps you or not??

  9. Hey Mukesh Good morning. I need more help from you dear. I have implemented as per you code and it's work perfectly. But Mukesh How can I give that bitmap image height and weight in DP? I want that cropped images circular shape in "80*80 DP" ... so please could you please help me?

    Thanks,
    Gaurav

    ReplyDelete
  10. Hey , there is two way to achieve this:
    1. Using xml, simply provide the layout_height and layout_width as 80*80 dp Or
    2. Using java first find the id of imageview and then
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
    LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    params.width = 80;
    params.height = 80;
    imgView.setLayoutParams(params);

    In this way you can do it in java.

    ReplyDelete
  11. hey dear Mukesh, I have did something else. I have implemented method to get DP to pixel value.. and it work perfectly. :) See below code:

    public static int getDPEquivalentPixels(Context context, float dp){
    DisplayMetrics metrics = context.getResources().getDisplayMetrics();
    int pixels = (int) (metrics.density * dp + 0.5f);
    return pixels;
    }

  12. Thanx Gaurav, for sharing your code and I like the way you did.The another and good way to do this.

    thanks a lot...

  17. hello, have you tried using "Oval" in xml, how its look like ?

    ReplyDelete
  18. Yes Mukesh I just replaced and checked.However after setting the image i cannot see the border i have used your above method getRoundedShape() and changed the targetWidth and targetHeight to 150 dp also tried using 50dp but still only the image is visible not the border around it.

  31. Hello Mukesh,

    I am using your source code from git.
    after it execute line

    startActivityForResult(cropIntent, PIC_CROP);

    in performcrop() function, its not entering onActivityResult() fuction.

    I can see that it is failing at line

    if (resultCode == RESULT_OK)
    [ while its not failing at this line when onActivityResult() is being called by startActivityForResult(captureIntent, CAMERA_CAPTURE); line ]

    Any idea why its happening.

    I am using Eclipse and virtual device manager.
