compiledClipInstance.tintPercent
Read-only property; a string that, when the Color Effect Property Inspector is using style tint (colorMode == 'tint'), returns the tint percentage from -100 to 100. Otherwise, using this property results in an error.
The following example illustrates use of this property:
var elem = fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0];
if (elem.colorMode = 'tint') {
fl.trace(elem.tintColor);
fl.trace(elem.tintPercent);
}
