Util::RotateCaptcha - captcha recognition via supported services
Overview of the scraper
This scraper is typically used as a plug-in component in other scrapers where it may be necessary to solve image-based captchas that require the number of degrees to rotate the image as an answer.
The principle of this scraper's operation consists of sending the captcha image to a solving service and receiving back the number of degrees the image needs to be rotated. The accuracy of the solving depends solely on the solving service.
