Dynamic Crop

Hi there, ı maked an app its working stabile but ı have problem with crop screen.
I normally used android crop plugin but ıts not enough for me so ı searched internet and ı found the Scanbot maybe you see already the plugin if you not you can see this link :> https://scanbotsdk.github.io/documentation/cordova/
So this point ı mailled the scanbot and ı asked price its 12.500 euro for year its a lot of money for me.Finally ı want to ask you do you know any plugin or site about dynamic crop.Thanks for suggestions.
