Create Annotations with 'author' name tool property

Philip Cord‌ has kindly sent me this code that allows to create annotations with the "Author" tool property (older versions than CS3 couldn't get this on script listener - only on the CS3 script listener).

Hope it helps anyone like me that can't have access anymore to CS3

var colour = new SolidColor();
colour.rgb.hexValue = 'ff00ff';
selectNote(0);
colourNote(colour);
addAuthorToNote("Author Name");


function colourNote(colour) {
var Saturation = colour.hsb.saturation;
var Brightness = colour.hsb.brightness;
var Hue =colour.hsb.hue;
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putEnumerated( stringIDToTypeID('annotation'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
desc.putReference( charIDToTypeID('null'), ref );
var desc2 = new ActionDescriptor();
var desc3 = new ActionDescriptor();
desc3.putUnitDouble( charIDToTypeID('H   '), charIDToTypeID('#Ang'), Hue );
desc3.putDouble( charIDToTypeID('Strt'), Saturation );
desc3.putDouble( charIDToTypeID('Brgh'), Brightness);
desc2.putObject( charIDToTypeID('Clr '), charIDToTypeID('HSBC'), desc3 );
desc.putObject( charIDToTypeID('T   '), stringIDToTypeID('annotation'), desc2 );
executeAction( charIDToTypeID('setd'), desc, DialogModes.NO );
};
function selectNote(number) {
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putIndex( stringIDToTypeID('annotation'), number );
desc.putReference( charIDToTypeID('null'), ref );
try{
executeAction( charIDToTypeID('Shw '), desc, DialogModes.NO );
}catch(e){}
};
function addAuthorToNote(Author) {
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putEnumerated( stringIDToTypeID('annotation'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
desc.putReference( charIDToTypeID('null'), ref );
var desc2 = new ActionDescriptor();
desc2.putString( charIDToTypeID('Athr'),  Author);
desc.putObject( charIDToTypeID('T   '), stringIDToTypeID('annotation'), desc2 );
executeAction( charIDToTypeID('setd'), desc, DialogModes.NO );
};


function makeAnnotation(X,Y,Width,Height) {
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putClass( stringIDToTypeID('annotation') );
desc.putReference( charIDToTypeID('null'), ref );
var desc2 = new ActionDescriptor();
var desc3 = new ActionDescriptor();
desc3.putUnitDouble( charIDToTypeID('Hrzn'), charIDToTypeID('#Pxl'), X ); 
desc3.putUnitDouble( charIDToTypeID('Vrtc'), charIDToTypeID('#Pxl'), Y ); 
desc2.putObject( charIDToTypeID('Lctn'), charIDToTypeID('Pnt '), desc3 );
var desc4 = new ActionDescriptor();
desc4.putUnitDouble( charIDToTypeID('Hrzn'), charIDToTypeID('#Pxl'), Width );
desc4.putUnitDouble( charIDToTypeID('Vrtc'), charIDToTypeID('#Pxl'), Height );
desc2.putObject( charIDToTypeID('Sz  '), charIDToTypeID('Ofst'), desc4 );
desc2.putEnumerated( stringIDToTypeID('annotType'), stringIDToTypeID('annotType'), stringIDToTypeID('annotText') );
desc.putObject( charIDToTypeID('Usng'), stringIDToTypeID('annotation'), desc2 );
executeAction( charIDToTypeID('Mk  '), desc, DialogModes.NO );
};
