Modify / Update a JPEG image programmatically to add a text

Question

I was wondering if there is an image library in .NET which would allow me to open a JPEG image on the fly and add a text field (for ex: Software version) Basically I should be able to send the software version to this library. And this image based library should modify/add a text to the image and save it.

Answer 1

You want to use the System.Drawing namespace. See this:

Is there a way to programmatically add text to a System.Drawing.Image?

Answer 2

Image origImage;
using (Stream s = new FileStream(path, FileMode.Open, FileAccess.Read);
{
    origImage = Image.FromStream(s);
}

using (Image newImage = new Bitmap(origImage))
{
    Graphics graphics = Graphics.FromImage(newImage);
    graphics.DrawString("Software version: " + version, font, Brushes.Black, 0, 0);

    newImage.Save(newPath, ImageFormat.Jpeg);
}

origImage.Dispose();
