I am using the following script for drawing a set of paths onto a photoshop image.

var docRef= app.activeDocument;
app.displayDialogs = DialogModes.NO;

var currentRulerUnits = app.preferences.rulerUnits;
var currentTypeUnits = app.preferences.typeUnits;
var currentDialogMode = app.preferences.displayDialogs;

app.preferences.rulerUnits = Units.PIXELS;
app.preferences.typeUnits = TypeUnits.PIXELS;


var height= docRef.height;
var width = docRef.width;


var isHorizontal = false;
var backgroundlayer = docRef.artLayers.getByName("Background");

var layer1,layer2,layer3,layer4;
if(isHorizontal)
{
// Copy and paste the layers in such a way that they are in a horizontal orientation.
layer1 = backgroundlayer.duplicate();
layer1.resize(120,120,AnchorPosition.TOPCENTER)
layer1.name = "A"
layer1.translate(0,height*(-0.5));

layer2 = backgroundlayer.duplicate();
layer2.resize(120,120,AnchorPosition.BOTTOMCENTER)
layer2.name= "B"
layer2.translate(0,height*(0.5));

layer3 = backgroundlayer.duplicate();
layer3.resize(120,120,AnchorPosition.TOPCENTER);
layer3.name = "C";
layer3.translate(0,height*(-0.5));

layer4 = backgroundlayer.duplicate();
layer4.resize(120,120,AnchorPosition.BOTTOMCENTER);
layer4.name= "D";
layer4.translate(0,height*(0.5));
}
else
{
layer1 = backgroundlayer.duplicate();
layer1.resize(120,120,AnchorPosition.MIDDLELEFT);
layer1.name = "A";
layer1.translate(width*(-0.5),0);

layer2 = backgroundlayer.duplicate();
layer2.resize(120,120,AnchorPosition.MIDDLERIGHT);
layer2.name= "B";
layer2.translate(width*(0.5),0);

layer3 = backgroundlayer.duplicate();
layer3.resize(120,120,AnchorPosition.MIDDLELEFT);
layer3.name = "C";
layer3.translate(width*(-0.5),0);

layer4 = backgroundlayer.duplicate();
layer4.resize(120,120,AnchorPosition.MIDDLERIGHT);
layer4.name= "D";
layer4.translate(width*(0.5),0);
}

var topXspread = .18; // 25 % Percentage expressed as decimal
var topYhighspread = 0.2; // 20 %
var topYlowspread = 0.6; // 80%
var yminspread = 0.05; // 5 %
var smalltoffset = yminspread/2;
var overallYoffset = 100; // units are in pixels
var midpointYoffset = -75;

var point1 = GeneratePathPointInfo(Math.floor((width/2) * (1 - topXspread)),overallYoffset+Math.floor(height/2 *(1 + yminspread)));
var point2 = GeneratePathPointInfo(Math.floor((width/2)),overallYoffset+Math.floor(height*(topYhighspread)));
var point3 = GeneratePathPointInfo(Math.floor((width/2)*(1 + topXspread)),overallYoffset+Math.floor(height/2 *(1 + yminspread)));
var point4 = GeneratePathPointInfo(Math.floor((width/2)),overallYoffset+Math.floor(height* topYlowspread));
var point5 = GeneratePathPointInfo(Math.floor((width/2)),midpointYoffset+overallYoffset+Math.floor(height/2));


GenerateTrianglePathItem(point1,point2,point4,"bigtleft",docRef);
GenerateTrianglePathItem(point2,point3,point4,"bigtright",docRef);
GenerateLinePathItem(point2,point4,"vertical",docRef);
GenerateLinePathItem(point1,point5,"lineleft",docRef);
GenerateLinePathItem(point3,point5,"lineright",docRef);


var point1small = GeneratePathPointInfo(Math.floor(width/2 * (1 - topXspread)),overallYoffset+Math.floor((height/2 *(1 + yminspread))+ (height *smalltoffset)));
var point3small = GeneratePathPointInfo(Math.floor(width/2*(1 + topXspread)),overallYoffset+Math.floor((height/2 *(1 + yminspread))+ (height *smalltoffset)));
var point4small = GeneratePathPointInfo(Math.floor(width/2),overallYoffset+Math.floor((height* topYlowspread)+ (height *smalltoffset)));
var point6small = GeneratePathPointInfo(Math.floor(width/2),overallYoffset+Math.floor((height* topYlowspread)+ (height * 6 * smalltoffset)));
GenerateTrianglePathItem(point1small,point4small,point6small,"smalltleft",docRef);
GenerateTrianglePathItem(point3small,point4small,point6small,"smalltright",docRef);
GenerateLinePathItem(point4small,point6small,"verticalsmall",docRef);

function GenerateTrianglePathItem(point1,point2,point3,name,docRef){
var spi = new SubPathInfo();
spi.closed = true;
spi.operation = ShapeOperation.SHAPEXOR;
spi.entireSubPath = [point1,point2,point3];
var line = docRef.pathItems.add(name, [spi]);
};

function GenerateLinePathItem(point1,point2,name,docRef){
var spi = new SubPathInfo();
spi.closed = true;
spi.operation = ShapeOperation.SHAPEXOR;
spi.entireSubPath = [point1,point2];
var line = docRef.pathItems.add(name, [spi]);
};

function GeneratePathPointInfo(x,y){
var startPoint = new PathPointInfo();
startPoint.anchor = [x,y];
startPoint.leftDirection = [x,y];
startPoint.rightDirection = [x,y];
startPoint.kind = PointKind.CORNERPOINT;
return startPoint;
};


The co-ordinates for the points (Point1, 2, 3 ..) are being calculated correctly and are withing the bounds of the image. However, the final path drawn is being drawn completely outside the image bounds.

Can anyone help me with why this is happening so?
