trueSize or min, maxsize not working for large image

[Utsaww]

Hi I am trying to fix my image cropping area like 500x500 or any desire, but it is not possible with trueSize or minSize or maxSize, I have huge large images like 1600x2000 which covers all the browser area so I need a resize method.

   `Jcrop.load('target').then(img => {
        jcp = Jcrop.attach(img, { multi: true });
        jcp.setOptions({
            minSize: [250, 250],
            maxSize: [250, 350]
        });
      
    });`
