相关API

addCurves

add such curves,receive an Array like pointPositions

curves.addCurves([[[140.80, 15.90],[151.498262,-18.690718]]])

refreshCurvesCoords

refresh curves coords , I want to provide a option to init the lineCoords when you use the addCurves API at frist , finally, I decide to make an API for someone use.

//  maybe addCurves ...
curves.refreshCurvesCoords()

removeFeatureByIndex

this index means pointPositions index

curves.removeFeatureByIndex(0) // delete pointPosition[0] related features

destroy

delete the relevant layer and event

curves.destroy()
