Use round cropping

roundCrop(optional, boolean || object) - Activates the round cropping feature for an original image. If the value is true, then the feature returns a circular cropped image that’s centered from the original image and has a diameter of the smallest edge of the original image. For example:

const imageRequest = JSON.stringify({
    bucket: "<myImageBucket>",
    key: "<myImage.jpeg>",
    edits: {
        roundCrop: true
    }
})

The following roundCrop variables are shown in the following code sample:

roundCrop.rx (optional, number) - Specifies the radius along the x-axis of the ellipse. If a value isn’t provided, the image handler defaults to a value that’s half the length of the smallest edge. roundCrop.ry (optional, number) - Specifies the radius along the y-axis of the ellipse. If a value isn’t provided, the image handler defaults to a value that’s half the length of the smallest edge. roundCrop.top(optional, number) - Specifies the offset from the top of the original image to place the center of the ellipse. If a value isn’t provided, the image handler defaults to a value that’s half of the height. roundCrop.left (optional, number) - Specifies the offset from the left-most edge of the original image to place the center of the ellipse. If a value isn’t provided, the image handler defaults to a value that’s half of the width.

const imageRequest = JSON.stringify({
    bucket: "<myImageBucket>",
    key: "<myImage.jpeg>",
    edits: {
        roundCrop: {
            rx: 30,   // x-axis radius
            ry: 20,   // y-axis radius
            top: 300, // offset from top edge of original image
            left: 500 // offset from left edge of original image
        }
    }
})
