where i call zoom() right after initialization or Or set a value for startTransform in the options ?
i want default value zero and also when load image should also zoom out how to do this ?

Answer

Either call zoom() right after initialization

$elem.panzoom("zoom", 1.1, {silent: true})  // +10%

Or set a value for startTransform in the options

$elem.panzoom({
    //...
    startTransform: "scale(1.1)"  // +10%
})

(from this issue: https://github.com/timmywil/jquery.panzoom/issues/218)

Edit:

(function() {
    var $section = $('#focal1').first();

    var elements = $section.find('.panzoom1');

    // initialize
    elements.panzoom({
        startTransform: 1.0,  // = no zoom
        $zoomIn: $section.find(".zoom-in-1"),
        $zoomOut: $section.find(".zoom-out-1"),
        $zoomRange: $section.find(".zoom-range-1"),
        $reset: $section.find(".reset-1")
    });

    // set new zoom value with animation
    elements.panzoom("zoom", 2.0, { animate: true });  // = 200%
})();
