Ask for advice on the problem of filling circle pictures in FabricJS Canvas

I use the FabricJS library, how to achieve the effect of the above picture? If you achieve this fixed area, no matter how much the filled image is dragged, it will not be allowed to go beyond the circle, similar to the effect of cropping. Wait for advice
