Recreate gradient thru script

I'm trying to recreate a gradien thru script... but i can't seem to use the following functions:

GradientColor ---> hiliteAngle, hiliteLength, length, matrix and origin.

Please help!

I've enclosed some jpg and the script sofar:

var omf = 2.834645;
var x=0;
var y=0;
var verschuivingx = 0;
var verschuivingy = 0;

var size= 0;

docPreset = new DocumentPreset;
docPreset.width = 100*omf;
docPreset.colorMode = DocumentColorSpace.CMYK
docPreset.previewMode = DocumentPreviewMode.OverprintPreview;
docPreset.rasterResolution = DocumentRasterResolution.HighResolution;
docPreset.title = "testgradientfile";
docPreset.rulerUnits = RulerUnits.Millimeters;
docPreset.height = (100*omf);
docPreset.name = "testgradientfile";
var doc = app.documents.addDocument(DocumentColorSpace.CMYK,docPreset);
app.activeDocument.layers[0].name = "testgradientfile";

var line = doc.pathItems.add();
line.setEntirePath(Array(Array(((x+185.561154924162+verschuivingx)*omf),((y+141.7774260533 51+size - verschuivingy)*omf)),Array(((x+79.7277966023964+verschuivingx)*omf),((y+141.777426053351+ size - verschuivingy)*omf)),Array(((x+79.7277966023964+verschuivingx)*omf),((y+247.610784375116+ size - verschuivingy)*omf)),Array(((x+185.561154924162+verschuivingx)*omf),((y+247.610784375116+ size - verschuivingy)*omf))));
