Question

I need the easy to learn & fast method for generating image from background image, texts and after that saving as JPEG format.

What you can suggest? Any library or tutorial on this? Important criteria is simpleness.

Answer 1

I usually do this using GDI+. There are lots of tutorials on this on the net, but basically what you need to do is something like this:

using(Image image = new Bitmap(Width, Height))
using (Graphics g = Graphics.FromImage(image)) {
  g.Draw....
  g.Draw....
  image.Save(filename, ImageFormat.Jpeg);
}

The calls to Draw.... you can draw primitives, images, text and so forth.

Also remember that is text looks jagged, you have methods on the Graphics object to smooth this out. In this case g.TextRenderingHint = TextRenderingHint.AntiAlias;

There are also other options to make it look better, if you feel it is jagged. The default settings is geared more towards performance than quality, so if you want high quality you need to set this yourself. g.SmoothingMode set to for example HighQuality will make your round primitives look much smoother than the default configuration.

It’s really easy to use, and to make the final image look like you want it to, so give it a try!
