JQuery JCrop - How to set a fixed size selection area?

Question

I'm trying to figure out how to fix the selection box size under JCrop. The documentation mentions how to set an initial selection area but not how to make it fixed size. Does anybody knows how could I make it fixed. Thanks in advance.

You are basically looking for the API section. Having extensively used this plugin myself, I know exactly what you're looking for:

var api;
var cropWidth = 100;
var cropHeight = 100;

$(window).load(function() {

    // set default options
    var opt = {};

    // if height and width must be exact, dont allow resizing
    opt.allowResize = false;
    opt.allowSelect = false;

    // initialize jcrop
    api = $.Jcrop('#objectId', opt);

    // set the selection area [left, top, width, height]
    api.animateTo([0,0,cropWidth,cropHeight]);

    // you can also set selection area without the fancy animation
    api.setSelect([0,0,cropWidth,cropHeight]);

});
