Why another captcha generator?

I want a simple and framework-independent way to generate captcha. It also should be flexible, at least allow me to pick my favorite font.

install

go get github.com/steambap/captcha

usage

func handle(w http.ResponseWriter, r *http.Request) {
    // create a captcha of 150x50px
    data, _ := captcha.New(150, 50)

    // session come from other library such as gorilla/sessions
    session.Values["captcha"] = data.Text
    session.Save(r, w)
    // send image data to client
    data.WriteImage(w)
}
