This is an ionic 4 plugin to input signature based on wulfsolter repository.
It's HTML5 canvas based and uses variable width Bézier curve interpolation based on Smoother Signatures post by Square. It works in all modern desktop and mobile browsers and doesn't depend on any external libraries.
This project was tested in ionic 4.0.0-beta.15 for my personal purposes
