How to change avatar image height and width

Hi,

I just looking for the avatar image with specified height and width. As i'm receiving the image size with fixed height and width of the following API call

/restapi/vc//users/id/<user-id>/profiles/avatar

/restapi/vc/users/id/<user-id>/profiles/avatar/size/message

Both of the above API returns 65x37px. But i just looking for the 67*37px image. So could you please guide me on how to get it.
