How can I toggle the "Ignore Color" button with a script?

/* Here is the full code as text.

@VMPrinting,

It will be easy if you have share code as a text as it helps to debug easily. Also, as per the documentation the setting of property ignoreWhite work only when tracingMethod is set to TracingMethodType.TRACINGMETHODABUTTING.

Hi @VMPrinting, it might help to set all the tracing options yourself. Have a look at the Tracing Object, and more importantly, TracingOptions.

Here is a script for example:

(function () {

    var doc = app.activeDocument,
        item = doc.selection[0];

    if (typeof item.trace !== 'function') {
        alert('Please select a traceable page item.');
        return;
    }

    var itemTrace = item.trace(),
        tracingOptions = itemTrace.tracing.tracingOptions;

    tracingOptions.tracingMode = TracingModeType.TRACINGMODEBLACKANDWHITE;
    tracingOptions.ignoreWhite = true;
    tracingOptions.threshold = 128;
    tracingOptions.pathFidelity = 50;
    tracingOptions.cornerFidelity = 20;
    tracingOptions.fills = true;
    tracingOptions.strokes = false;
    tracingOptions.cornerAngle = 135;

    // var tracedItem = tracingOptions.expandTracing();
    // tracedItem.selected = true;

})();

If you need to use a preset, then the TracingOptions object has "loadFromPreset" and "storeToPreset" methods. You could load the one you want, and then set the tracingOptions.ignoreWhite property.
