name

Name of the annotation type

uiFunction

Shiny module UI function that takes an id parameter and returns a tagList.

serverFunction

Shiny module server function that returns a list with items:

arguments: Function that returns a list of arguments to be passted to drawFunc
drawFunc: Function that draws the annotation. Takes a list of arguments as returned above, plus x and y coordinates as the first two arguments, and (possibly) a named xpd argument. Should NOT be reactive nor depend on the UI.
script: Function that returns a string containing the code to draw the annotation. Takes the same arguments as drawFunc. Should NOT be reactive nor depend on the UI.
getBoundingRect: Function that returns vector containing the bounding rect of the annotation for hit testing. Takes the same arguments as drawFunc, returns c(left, bottom, right, top).
focus: Function that highlights an annotation (typically by drawing a red border). Takes the same arguments as drawFunc.
updateInputs: Function that updates the UI to reflect the argument list. Takes the same arguments returned by arguments.
