Get or set the starting two-dimensional coordinates of the linear gradient

Example


--! luart-extensions
import ui
require "canvas"

-- create a simple Window
local win = ui.Window("LinearGradient.start sample", "fixed", 500, 400)

-- create a Canvas
local canvas = ui.Canvas(win)
canvas.align = "all"

local gradient = canvas:LinearGradient { [0] = 0x00FFFFFF, [1] = 0x00008bFF }
gradient.start = { 0, 0 }
gradient.stop = { canvas.width, canvas.height }

function canvas:onPaint()
  self:begin()
  self:fillrect(0, 0, canvas.width, canvas.height, gradient)
  self:flip()
end

await win:showasync()
