having issue with display.newText

Audio and Graphics
#1

i’m getting this in the terminal

WARNING: Due to system limitations, display.newText() height is going to be increased to nearest multiple of 4: 1843 ===> 1844.
 

im using build 1135

heres my config.lua

[lua]

    local aspectRatio = display.pixelHeight/display.pixelWidth

    application =
    {
        content =
        {
            width = 320 * (aspectRatio>1.5 and 1 or 1.5/aspectRatio),
            height = 480 * (aspectRatio<1.5 and 1 or aspectRatio/1.5),
            scale = “letterbox”,

            imageSuffix =
            {
                ["@2x"] = 1.5,
                ["@4x"] = 3.0,
            },
        },
    }

[/lua]

and here’s how i tried to correct then problem

where var.displayLength is set to contentHeight - 50px

[lua]

var.displayLength = var.displayLength+(var.displayLength%4)
      print("__"…var.displayLength)
      appText = display.newText( appLogGroup, “”, _api.oriX, _api.oriY+20, _api.cntW-_api.oriX, var.displayLength, native.systemFontBold, 12*var.scale )
[/lua]

now this works fine in sim on iphone,iphone4,iphone5 but i get the warning on most other devices

using the above config.lua file and this code below you can try it in the various sims and check the terminal

[lua]

local _w = display.contentWidth

local _h = display.contentHeight

local _x = display.screenOriginX

local _y = display.screenOriginY

local textHeight = ((_h - _y) - 50)

print("textHeight = "…textHeight)

textHeight = textHeight + (4 - textHeight%4)

print("new textHeight = "…textHeight)

local txt = display.newText( “”, _x, _y+20, _w-_x, textHeight, native.systemFontBold, 12 )
[/lua]

happens in 1195 also

it seems as if some devices in the sim are not using content scaling for newText

#3

Because text renders to an OpenGL texture, things divisible by 4 are common place (like masks).   I think this is a mostly harmless warning.  If you set a text box width of 199, it’s going to make the box 200 and spew that error.  Those extra 1-3 pixels will rarely be hit the way things wrap, so it shouldn’t impact your UI design that much.   Brent sent a message to the engineers earlier today to make sure.

Thx rob
But I have to determine how big to make the text box for multiple devices using multiple orientations and at times the box needs to be recreated over and over. And I can’t figure out how to calculate the size I need to make the box so this doesn’t happen.
I can send you the code to look at if you want. It’s too big to post it’s almost 1000 lines of code

#5

I think you can just ignore the warning and go on.  I’m not sure how you’re setting the size now.  But in my apps, I just you whatever size I want and let Corona deal with rounding it up to the next divisible by 4 number.

#6

I’m fine with that but read that it causes a slight delay. Although I haven’t noticed one the code is for a module that others will use so not sure if it will cause a delay in their code.

#7

just double checked my code the text box is only created once the warning is displayed every time the text is updated
