filter.blurX
Property; a float value that specifies the amount to blur in the x direction, in pixels. Acceptable values are between 0 and 255. This property is defined for Filter objects with a value of "bevelFilter", "blurFilter", "dropShadowFilter", "glowFilter", "gradientBevelFilter", or "gradientGlowFilter" for the filter.name property.
The following example sets the blurX value to 30 and the blurY value to 20 for the Blur filters on the selected object(s):
var myFilters = fl.getDocumentDOM().getFilters();
for(i=0; i < myFilters.length; i++){
if(myFilters[i].name == 'blurFilter'){
myFilters[i].blurX = 30;
myFilters[i].blurY = 20;
}
}
fl.getDocumentDOM().setFilters(myFilters);document.setFilterProperty(), filter.blurY
