Question

I want to draw a text within an image in C# by using the method drawstring.But how can i obtain the co-ordinates of the clicked position and how can i relate this to the dimension of the image.
Please Help.

Working example:

private Bitmap _bmp = new Bitmap(250, 250);

public Form1()
{
  InitializeComponent();   

  panel1.MouseDown += new MouseEventHandler(panel1_MouseDown);
  panel1.Paint += new PaintEventHandler(panel1_Paint);

  using (Graphics g = Graphics.FromImage(_bmp))
    g.Clear(SystemColors.Window);
}

private void panel1_Paint(object sender, PaintEventArgs e)
{
  e.Graphics.DrawImage(_bmp, new Point(0, 0));

}

private void panel1_MouseDown(object sender, MouseEventArgs e)
{
  using (Graphics g = Graphics.FromImage(_bmp))
  {
    g.DrawString("Mouse Clicked Here!", panel1.Font, Brushes.Black, e.Location);
  }
  panel1.Invalidate();
}

You might want to use TextRenderer instead of DrawString. DrawString has issues.

TextRenderer.DrawText(g, "Mouse Clicked Here!", panel1.Font, e.Location, Color.Black);
