Get information about layer styles with script

Question

Is there a way for a script to get information about the currently existing layer styles on a layer?

For example, can I find out if a layer has a dropShadow, and if so, can I find that dropShadow's size, transparency, color, etc...?

If you don't have CS4 you will need Xbytor's script. With CS4 you can the the descriptor from the layer

var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var desc = executeActionGet(ref).getObjectValue(stringIDToTypeID('layerEffects'));
if( desc.hasKey( stringIDToTypeID('dropShadow') ) ){
     desc = desc.getObjectValue(stringIDToTypeID('dropShadow'));
     alert('opacity = '+ desc.getDouble( stringIDToTypeID('opacity') ) );
     alert('distance = '+ desc.getDouble( stringIDToTypeID('distance') ) );
     alert('spread = '+ desc.getDouble( stringIDToTypeID('chokeMatte') ) );// spread
     alert('blur = '+ desc.getDouble( stringIDToTypeID('blur') ) );
     var desc = desc.getObjectValue(stringIDToTypeID('color'));
     var r = desc.getDouble( stringIDToTypeID('red') ) ;
     var g = desc.getDouble( stringIDToTypeID('green') ) ;
     var b = desc.getDouble( stringIDToTypeID('blue') ) ;
     alert( 'r = ' + r +'\rg = ' + g + '\rb = ' + b );
}

There is no easy way to get this information, but you can get to it.

Get my xtools library (from ps-scripts.sourceforge.net) and in there you will find xtools/xlib/Styles.js.

In there, you will find Styles.getLayerStyleDescriptor(). The will get you the ActionDescriptor that

describes the styles applied to a layer.
