#1 
display.newImage( [parent,] filename [,baseDir] [,x,y] [,isFullResolution])

when i set true or false, it show same resolution on screen.

as docs say ,when i set false, it should auto scale down to fit the screen.but it didn’t.

config.lua

 width = 320, height = 480,

main.lua

local myImage = display.newImage( "blue-37852.png",display.contentCenterX,display.contentCenterY,true )

blue-37852.png resolution is 1920X1920.
