install
npm install @disjukr/croquis-js
# or
yarn add @disjukr/croquis-jsstroke protocol
brush-related functions in croquis.js are working on the stroke protocol.
stroke protocol consists of the down method and the move and up methods of the drawing context.
down method means that the stylus pen has started drawing a stroke. it returns the drawing context containing the move and up methods.
move means that the stylus pen draws a stroke, and up means that the stroke ends.
stroke protocol makes it easy to add features such as stabilization without having to modify the drawing code very much.
look at the simple brush example and the pulled string stabilizer example. you can see that the code is not different except for the part injecting the settings and the part drawing the guide.
