Characters outside of image

Hi,
I've got something like this on attached image. The characters are out of an image rectangle. The version of component is 3.13.1.

The code is like that:
var s = _captcha.GenerateCaptchaImageFileStream( HttpContext.Session, 330, 100 ); return s;

Is it a bug or wrong implementation?

It is recommended to add case-ignoring

It is suggested to add case-ignoring judgment when making verification code judgment here.
like this:
var isValid = userInputCaptcha.Equals(HttpContext.Session.GetString(CaptchaCodeSessionName), StringComparison.OrdinalIgnoreCase);
