https://forums.adobe.com/message/9810176#9810176

function drawCustomShape(points, color) {
    try {
        
        var doc = app.activeDocument,
            countPoints = points.length,
            lineArray = [];
        for (var i = 0; i < countPoints; i++) {
            lineArray = new PathPointInfo;
            lineArray.kind = PointKind.CORNERPOINT;
            lineArray.anchor = [Number(points[0]), Number(points[1])];
            lineArray.leftDirection = lineArray.anchor;
            lineArray.rightDirection = lineArray.anchor;
        }
        var lineSubPathArray = new SubPathInfo();
        lineSubPathArray.closed = true;
        lineSubPathArray.operation = ShapeOperation.SHAPEADD;
        lineSubPathArray.entireSubPath = lineArray;
        var myPathItem = doc.pathItems.add("myPath", [lineSubPathArray]);
        //Werte für die Farbfläche bestimmen
        var desc1 = new ActionDescriptor();
        var ref1 = new ActionReference();
        ref1.putClass(stringIDToTypeID("contentLayer"));
        desc1.putReference(charIDToTypeID("null"), ref1);
        var desc2 = new ActionDescriptor();
        var desc3 = new ActionDescriptor();
        var desc4 = new ActionDescriptor();
        desc4.putDouble(charIDToTypeID("Rd  "), color.rgb.red); // R
        desc4.putDouble(charIDToTypeID("Grn "), color.rgb.green); // G
        desc4.putDouble(charIDToTypeID("Bl  "), color.rgb.blue); // B
        desc3.putObject(charIDToTypeID("Clr "), charIDToTypeID("RGBC"), desc4);
        desc2.putObject(charIDToTypeID("Type"), stringIDToTypeID("solidColorLayer"), desc3);
        desc1.putObject(charIDToTypeID("Usng"), stringIDToTypeID("contentLayer"), desc2);
        executeAction(charIDToTypeID("Mk  "), desc1, DialogModes.NO);
        //Pfad entfernen
        myPathItem.remove();
    } catch (e) {
        alert(e + "\n" + e.line);
    }
}
var color = = new SolidColor();
color.rgb.hexValue = '808080';
var points = [[1000,250], [1250,750],[750,750] ];
drawCustomShape (points, color);

This works perfectly if the document has 72dpi, but not at 300dpi.

Do I have to convert something?

The Shape is at 300 dpi outside the document and is too big

Thanks in advance for the help
