Below is the method which will add a text as a water marked text to an image.
public Bitmap WaterMarkToImage(string ImagePath, string watermark)
{
Bitmap bmp;
bmp = new Bitmap(ImagePath);
Graphics graphicsObject;
int x, y;
try
{
//create graphics object from bitmap
graphicsObject = Graphics.FromImage(bmp);
}
catch (Exception e)
{
Bitmap bmpNew = new Bitmap(bmp.Width, bmp.Height);
graphicsObject = Graphics.FromImage(bmpNew);
graphicsObject.DrawImage(bmp, new Rectangle(0, 0,
bmpNew.Width, bmpNew.Height), 0, 0, bmp.Width,
bmp.Height, GraphicsUnit.Pixel);
bmp = bmpNew;
}
int startsize = (bmp.Width / watermark.Length);
//get the font size with respect to length of the string
//x and y cordinates to draw a string
x = 0;
y = bmp.Height / 2;
System.Drawing.StringFormat drawFormat =
new System.Drawing.StringFormat(StringFormatFlags.NoWrap);
//drawing string on Image
graphicsObject.DrawString(watermark, new Font("Verdana",
startsize, FontStyle.Bold),
new SolidBrush(Color.FromArgb(100, 255, 255, 255)), x, y, drawFormat);
//return a water marked image
return (bmp);
}
