ImageCropper中圆圈的长宽比

Question

I have been working on an app which requires crop image to set aspect ratio of profile picture . Right now I have set aspect ratio to (1,1) but it is Square . I want a circle cropped image, So please help me to find out what should be the aspect ratio for circle. I am using a An Open Source Image Cropper | Link for Documentation : HERE Keywords; Android Programming, App developer, Android Studio

CropImage.activity(imageUri)
                .setGuidelines(CropImageView.Guidelines.ON)
                .setAspectRatio(1,1)
                .start(this);

Answer 1

You can't crop an image to be a circle. Images must be rectangular. What you could do is manually cut out a circle and make the rest transparent.

Answer 2

Call the setCropShape() method of ActivityBuilder

CropImage.activity(imageUri)
         .setCropShape(CropImageView.CropShape.OVAL)
         ...
         .start(this);
