For isocp.shx the font has incorrect bulge and weird vertical alignment

[NikhilSP]

The solution to weird vertical alignment:

// Add code as parameter
private static TextShape _ParseCode(ShxFile file, uint code, byte[] data, double scale)
    {
        var currentP = new Point();
        var polyLines = new List<PolyLine>();
        var currentPolyLine = new List<Point>();
        var sp = new Stack<Point>();
        var isPenDown = false;

        for (int i = 0; i < data.Length; i++)
        {
            var cb = data[i];

            if (i == 0 && cb == code) continue; // add this

            switch (cb)
            {
                case 0x00:
                    break;

Solution for bulge (Problem was radian and center of bulge are not calculated properly) :

 private static IEnumerable<Point> _GenerateArcPoints(Point start, Vector2 distance, double bulge)
    {
        var end = start + distance;
        var isClockwise = bulge < 0;
        var isLargeAngle = false;
        bulge = Math.Abs(bulge);
        var halfLength = Vector2.Distance(distance, Vector2.Zero) / 2;
        var h = halfLength * bulge;
        var radian = 4 * Math.Atan(bulge);// Add This for correct radian
        var normal = new Vector2(distance.Y, -distance.X);
        normal.Normalize();

        var radius = Math.Abs(halfLength / Math.Sin(radian / 2));
        var temp = Math.Sqrt((radius * radius) - (halfLength * halfLength)); // Add This for correct center
        normal *= temp; // Add This for correct center

        var center = start + distance / 2;
        if (isLargeAngle ^ isClockwise)
            center += normal;
        else center -= normal;
