illustrator actions - live trace settings

Question

I'm trying to set a macro to batch vectorize png to svg vectors, but i'm stuck at the Live Trace action. Illustrator will only use the default preset, how can overwrite the default preset OR create an action using a custom preset ?

i use illustrator CS6

You can do this via scripting, a quick template example:

var traceobj = selection[0].trace();
var opt = traceobj.tracing.tracingOptions;

opt.cornerAngle = 90;
opt.fills = true;
opt.ignoreWhite = false;
opt.maxColors = 32;
opt.maxStrokeWeight = 0;
opt.minArea = 5;
opt.minStrokeLength = 3;
opt.outputToSwatches = true;
opt.palette = '';
opt.pathFitting = true;
opt.preprocessBlur = 0;
opt.strokes = false;
// threshold = 120 // BW only
opt.tracingMode = TracingModeType.TRACINGMODECOLOR

traceobj.tracing.tracingOptions = opt;
