filter.angle
Property; a float value that specifies the angle of the shadow or highlight color, in degrees. Acceptable values are between 0 and 360. This property is defined for Filter objects with a value of "bevelFilter", "dropShadowFilter", "gradientBevelFilter", or "gradientGlowFilter" for the filter.name property.
The following example sets the angle to 120 for the Bevel filters on the selected object(s):
var myFilters = fl.getDocumentDOM().getFilters();
for(i=0; i < myFilters.length; i++) {
if(myFilters[i].name == 'bevelFilter'){
myFilters[i].angle = 120;
}
}
fl.getDocumentDOM().setFilters(myFilters);
