Answer 1

You can use the DrawString method to write text out onto an image.

// Create string to draw.
String drawString = "Sample Text";

// Create font and brush.
Font drawFont = new Font("Arial", 16);
SolidBrush drawBrush = new SolidBrush(Color.Black);

// Create point for upper-left corner of drawing.
PointF drawPoint = new PointF(150.0F, 150.0F);

// Draw string to screen.
e.Graphics.DrawString(drawString, drawFont, drawBrush, drawPoint);

It's not clear if you are trying to add the text to the image or just display text on the image:

To the image:

using (Graphics g = Graphics.FromImage(yourImage))
{
  g.DrawString(...);
}

or On the image:

e.Graphics.DrawImage(...);
e.Graphics.DrawString(...);
