move the profile PB along the penlines inside the imagePB

Question

Hello, I have created the profile of a 2D image. Now I want to move the picturebox ( which graphics the profile) along the penline inside the 2D image picturebox.

Thanks. and below is the codes that i have used.

public FrmProfile()

{

InitializeComponent();int xmid = pictureBox1.Width / 2;

xLines =new int[] { xmid };

}

private Pen pen1 = new Pen(Color.Blue,2);

 

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)

{bool yline = false;

pictureBox4.Cursor =

Cursors.SizeWE;

 

 

int xminDistance = int.MaxValue;

int xSelectedLineIndex = 0;

for (int u = 0; u < xLines.Length; u++)

{

int dist = Math.Abs(e.X - xLines[u]);

 

 

if (dist < xminDistance)

{

xminDistance = dist;

xSelectedLineIndex = u;

}

}

selectedLineIndex = xSelectedLineIndex;

yline = false;

}

 

void pictureBox1_MouseMove(object sender, MouseEventArgs e)

{

bool yline = false;

pictureBox1.Cursor =

Cursors.SizeWE;

 

if ((MouseButtons & MouseButtons.Left) != MouseButtons.Left)

return;

if (yline != true && e.X > 0 && e.X < 1534)

xLines[selectedLineIndex] = e.X;pictureBox1.Invalidate();

pictureBox2.Invalidate();

}

void pictureBox4_Paint(object sender, PaintEventArgs e)

{

foreach (int x in xLines)

{

e.Graphics.DrawLine(pen1, x, 0, x, pictureBox1.Height);

}

}
