Draw Polygon

Question

Hello,

 

I cant draw polygon using system Drawing.

 

My Coordinates

 Name Y X H

5 0592612.238 0758030.902 1520.23

22 0592571.590 0758534.210 152.25

23 0592612.269 0758575.110 654.05

25 0592604.649 0758680.098 382.14

28 0592384.293 0758597.392 548.45

34 0592155.367 0758760.827 12.21

35 0592061.813 0758730.954 98.34

5 0592612.238 0758030.902 874.15

 

 this moment i am using only Y and X coord.

 

my code

brTacaka - is means number of point 

ime - is means point name

tacke3D - is class for reading file with coordinates 

 

int brTacaka = tacke3D.Count(i => i.ime != "");

System.Drawing.Graphics g;

Point[] p = new Point[brTacaka];

System.Drawing.Pen pen1 = new System.Drawing.Pen(Color.Blue, 2F);

List<double> minimumX = new List<double>();

List<double> minimumY = new List<double>();

for (int i = 0; i < brTacaka; i++)

{

minimumX.Add(tacke3D[i].x);

minimumY.Add(tacke3D[i].y);

}

double minX = minimumX.Min();

double minY = minimumY.Min();

for (int i = 0; i < brTacaka; i++)

{

int a = Convert.ToInt32(tacke3D[i].y - minY);

int b = Convert.ToInt32(tacke3D[i].x - minX);

p[i] = new Point(a, b);

}

g = pictureBox1.CreateGraphics();

g.DrawPolygon(pen1, p);

 

 

Picture box Weidght 485, Height 331

 

Where is the problem

 

Thanks in advance
