Path Segments: Convenience Functions for Path Segments

Description

These functions are convenience constructors for path segment objects of classes "PathMoveTo", "PathLineTo", "PathCurveTo" and "PathClosePath".

Usage

moveTo(x, y)
lineTo(x, y)
curveTo(x, y)
closePath(x, y)

Value

For moveTo, an object of class "PathMoveTo".

For lineTo, an object of class "PathLineTo".

For curveTo, an object of class "PathCurveTo".

For closePath, an object of class "PathClosePath".

Arguments

x

A numeric vector representing x-locations.

y

A numeric vector representing y-locations.

Details

For x and y, they should each be of length one so that they represent a single point location except in the case of curveTo. In the case of curveTo, it expects x and y vectors of length four, which represent control points in a cubic bezier curve.
