Using resolve() to get coordinates / position

I'm trying the get positions of a line, and since geometricBounds / visibleBounds just give me the frame position I thought I could get it through "resolve()". But I'm apparently missing something; every example I find for resolve() uses AnchorPoint and CoordinateSpaces, but I'm not sure how to reference them

 

Example:

const id = require("indesign");
const app = id.app;

// We only have one item (line) in the document
const line = app.activeDocument.pageItems.item(0); 
// Use resolve method, where all examples look like this:
const position = line.resolve(AnchorPoint.TOP_LEFT_ANCHOR, CoordinateSpaces.SPREAD_COORDINATES)[0];
console.log(position);

Which gives

ReferenceError: AnchorPoint is not defined

How do I set up my code so that it gets the correct "AnchorPoint.TOP_LEFT_ANCHOR" and "CoordinateSpaces.SPREAD_COORDINATES" ?

    As @rob day pointed out - you need to get into PathPoints collection of the Path(s) of the Object.

     

    But I don't think you need to use resolve() ?

    Or, if the line is pasted into a pageitem:

     

    var gl = app.activeDocument.pageItems[0].graphicLines[0].geometricBounds

alert("X: " +gl[1]+ "  Y: " + gl[0])

     

     

    To use resolve try this:

    var gl = app.activeDocument.pageItems[0].graphicLines[0]
var a = gl.paths[0].pathPoints[0].anchor

//returns points
alert(gl.resolve(a,CoordinateSpaces.PARENT_COORDINATES))

      Yes, this is probably what I'm after 🙂

      But how do I find the correct CoordinateSpace enum?

       

      Example, when I run this:

      var gl = app.activeDocument.pageItems[0].graphicLines[0]
var a = gl.paths[0].pathPoints[0].anchor

//returns points
alert(gl.resolve(a,CoordinateSpaces.PARENT_COORDINATES))

      I get a value for "a", but I get this error for the second parameter:

      ReferenceError: CoordinateSpaces is not defined

      Hi @Øyvind235243823c6v , Try getting graphicLines:

       

      var gl = app.activeDocument.graphicLines[0].geometricBounds

alert("X: " +gl[1]+ "  Y: " + gl[0])

      Yes, that gives me the frame position, but I need to get the position for the contents of the frame, i.e for each line start and end

       

      E.g. these two lines will give me the same geometricBounds:

       

      I need to find the find the x1,y1,x2,y2 point of each line. The x1,y1 of the blue line is not the x1,y1 of the black line

       

      I was probably a bit unclear describing my problem 🙂

       

      I've looked through all attributes and cannot find any reference, so I thought I needed to use a function like resolve()

       

      Is there any other attributes on 

      app.activeDocument.graphicLines

      that show these values?
