Util::RotateCaptcha - captcha recognition through supported services
Overview of the scraper
This scraper is usually used as a plug-in component in other scrapers, where it may be necessary to decipher captchas in the form of images and the response to which should be the number of degrees to rotate the image.
The principle of this scraper is to send the captcha image to the deciphering service and receive the number of degrees to rotate the image in response. The accuracy of deciphering depends exclusively on the deciphering service.
