PictureBox: Scale Width & Height

[jcis]

Add this on Top (Form level)

   private int mScaleWidth  = 5600;
   private int mScaleHeight = 5356;

Then this is the Paint Event named PaintIt (you can use another name) and a drawLine sub, use this one instead of e.Graphics.DrawLine

	private void PaintIt(object sender, System.Windows.Forms.PaintEventArgs e)
	{
		PB1.BackColor = System.Drawing.Color.White;
		
		//Square
		drawLine(e.Graphics, Pens.Black ,   1000, 1000, 2000, 1000);
		drawLine(e.Graphics, Pens.Black, 2000, 1000, 2000, 2000);
		drawLine(e.Graphics, Pens.Black, 2000, 2000, 1000, 2000);
		drawLine(e.Graphics, Pens.Black, 1000, 2000, 1000, 1000);
	}

	private void drawLine(Graphics Gr,Pen  Pn, int X1, int Y1, int X2, int Y2)
	{
		int ScaledX1 = (int) (((float) X1 / mScaleWidth) * PB1.ClientSize.Width);
		int ScaledX2 = (int) (((float) X2 / mScaleWidth) * PB1.ClientSize.Width);
		int ScaledY1 = (int) (((float) Y1 / mScaleHeight) * PB1.ClientSize.Height);
		int ScaledY2 = (int) (((float) Y2 / mScaleHeight) * PB1.ClientSize.Height);

		Gr.DrawLine (Pens.Black ,ScaledX1, ScaledY1, ScaledX2,ScaledY2);
	}

That should draw a Square using your coordinate system.
