- The "newImageRect" function selects the best image for the resolution of the current device
-- and displays it at the specified size. 
-- In the example below, the specified image size is 200 x 200 in base content coordinates.
-- (The base content size is 320x480, defined in config.lua)
 
-- If no high-resolution alternates are found, the base image filename is used instead.
-- See the config.lua file for the "imageSuffix" naming table for alternate images.
 
local myImage = display.newImageRect( "hongkong.png", 200, 200 )
myImage.x = display.contentWidth / 2
myImage.y = display.contentHeight / 2
 
 
-- Create text message labels
local label1 = display.newText( "Dynamic Image Resolution", 20, 30, native.systemFontBold, 20 )
label1:setTextColor( 190, 190, 255 )
local label2 = display.newText( "View as different simulated devices", 20, 60, native.systemFont, 14 )
label2:setTextColor( 190, 190, 255 )
local label3 = display.newText( "(Best image is chosen automatically)", 20, 80, native.systemFont, 14 )
label3:setTextColor( 190, 190, 255 )
