问PathItems生成未定义的is不是photoshop脚本中的对象

// create the array of PathPointInfo objects
// Declare a new array called lineArray
var lineArray = new Array();

// Firstly, add PathPointInfo() constructor to the array
lineArray.push(new PathPointInfo());

// declare various components to the array
// of which there are four types
// .kind - determines what type of corner
// .anchor - these are path points
// in order to given them x,y co-orrdinates we have to declare
// another new array with them
// and lastly
// direction - specifically leftDirection and rightDirection
// these are tangents to the bezier curve.
// Truthfully, don't understand how the numbers relate to how
// the tangents look in Photoshop
// by declaring a tangent as as anchor ie = lineArray[0].anchor
// the tangents are tucked away and are at the same point as
// the path point


lineArray[0].kind = 2 ;// for PsPointKind --> 2 (psCornerPoint)
lineArray[0].anchor = new Array(100, 100);
lineArray[0].leftDirection  = lineArray[0].anchor;
lineArray[0].rightDirection = lineArray[0].anchor;

// For the second point (and every subsequent point) 
// we need to push PathPointInfo() to the line array

lineArray.push(new PathPointInfo());

//  Since arrays are zero based, the first element
// of the lineArray is lineArray[0]
// the next point is lineArray[1]

lineArray[1].kind = 2
lineArray[1].anchor = new Array(150, 200);
lineArray[1].leftDirection   = lineArray[1].anchor;
lineArray[1].rightDirection =  lineArray[1].anchor;


// Next create a SubPathInfo object, which will hold the line array
// in its EntireSubPath property.
// It's similar to the above, but why it's needed is beyond me

var lineSubPathArray = new Array();
lineSubPathArray.push(new SubPathInfo());
lineSubPathArray[0].operation = ShapeOperation.SHAPEXOR;
// operation, not kind and therefore needs to be declared with ShapeOperation
// Uning an int just didn't work for me in PS CC 2018
lineSubPathArray[0].closed = false;
lineSubPathArray[0].entireSubPath = lineArray;


// create the path item, giving a unique name, 
// passing subpath to the add method
var myPathItem = docRef.pathItems.add("A Line", lineSubPathArray);

// stroke it so we can see something using the preset brush tool
myPathItem.strokePath(ToolType.BRUSH);
