macOS Highlighting only image over button when it is clicked

Hi all,

Right now when I set an image over a button and make it border-less and try to click it, it always shows a rectangular portion highlighted along with the image, which is the actual dimension of button clicked.

My requirement is: I want to highlight only the image over it, not the whole rectangular portion.

Can anyone suggest me some logic to implement it?

Thanks,

Monaj
