Question

Write an algorithm to create the zig-zag line in Scratch.

Answer 1

Answer:

private void DoTheTest()

{

Bitmap bmp = new Bitmap(970, 512);

var random = GenerateRandom(2500, bmp.Width, bmp.Height).ToArray();

var unity = GenerateUnity(2500, bmp.Width, bmp.Height).ToArray();

var ZigZag = GenerateZigZag(2500, bmp.Width, bmp.Height).ToArray();

using (Graphics g = Graphics.FromImage(bmp))

{

var tUnity = BenchmarkDraw(g, 200, unity);

var tRandom = BenchmarkDraw(g, 200, random);

var tZigZag = BenchmarkDraw(g, 200, ZigZag);

MessageBox.Show(tUnity.ToString() + "\r\n" + tRandom.ToString() + "\r\n" + tZigZag.ToString());

}

}

private double BenchmarkDraw(Graphics g, int n, PointF[] Points)

{

var Times = new List<double>();

for (int i = 1; i <= n; i++)

{

g.Clear(Color.White);

System.DateTime d3 = DateTime.Now;

DrawLines(g, Points);

System.DateTime d4 = DateTime.Now;

Times.Add((d4 - d3).TotalMilliseconds);

}

return Times.Average();

}

private void DrawLines(Graphics g, PointF[] Points)

{

g.DrawLines(Pens.Black, Points);

}
