int height = objImage.Height;
//height
int width = objImage.Width;

//Convert in to a Graphics object
System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bitmapimage);
//Creating Brush

System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.FromArgb(113, 255, 255, 255));


g.DrawString(" Anish ", new Font("Arial", 18, System.Drawing.FontStyle.Bold), brush, 0, 100);
