如何讓精靈適合多個設備的整個屏幕

Question

我一直在與corona幾個工作，我想知道如何使精靈（使用紋理打包機），並將其設置爲我的應用程序的背景。我也希望它能夠適應儘可能多的設備，而不會將任何精靈內容都裁剪掉。總之，我想精靈爲背景，而不會丟失任何精靈的內容

我希望這可以幫助您的裝修整個屏幕：

local _W = display.actualContentWidth 
local _H = display.actualContentHeight 

local bg = display.newImage('bg.jpg') 
bg.x, bg.y = display.contentCenterX, display.contentCenterY 


local mode = 'inside' 

-- the image will fill the device width/height exactly 
if mode == 'stretch' then 
    bg.width, bg.height = _W, _H 

-- the image will be scaled proportionally to fit inside the device width/height 
elseif mode == 'inside' then 
    local scale = math.min(_W/bg.width, _H/bg.height) 
    bg:scale(scale, scale) 

-- the image will be scaled proportionally to completely fill the area, 
-- allowing portions of it to exceed the bounds defined by device width/height 
elseif mode == 'outside' then 
    local scale = math.max(_W/bg.width, _H/bg.height) 
    bg:scale(scale, scale) 
end
