Description

Draw a, LCARS elbow polygon. This is a 90-degree rounded corner bend for top left, top right, bottom right and bottom left LCARS corner panels.

Usage

lcars_elbow(
  xmin,
  xmax,
  ymin,
  ymax,
  corner,
  width,
  height,
  ro = width/2,
  ri = height/2,
  n = 20,
  color = "atomic-tangerine",
  draw = TRUE
)

Value

draws a polygon
