            // Create the Font object for the image text drawing.
            Font objFont = new Font("Arial", 20, FontStyle.Bold, GraphicsUnit.Pixel);

            // Create a graphics object to measure the text's width and height.
            Graphics objGraphics = Graphics.FromImage(objBmpImage);

            // This is where the bitmap size is determined.
            intWidth = (int)objGraphics.MeasureString(sImageText, objFont).Width;
            intHeight = (int)objGraphics.MeasureString(sImageText, objFont).Height;

            // Create the bmpImage again with the correct size for the text and font.
            objBmpImage = new Bitmap(objBmpImage, new Size(intWidth, intHeight));

            // Add the colors to the new bitmap.
            objGraphics = Graphics.FromImage(objBmpImage);

            // Set Background color
