Retina image gotchas?

Hey all,

I’ve got my app running fine now, after figuring out some differences between the simulator’s treatment of the mic and my iPhone’s treatment of it. My problem now is that the device does not want to load retina graphics. I’ve got files named appropriately (as far as I know):

app_title.png

app_title@2x.png

My config file is this:

if ( string.sub( system.getInfo("model"), 1, 2 ) == "iP" and display.pixelHeight \>= 960 ) then &nbsp; &nbsp;application = &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; content = &nbsp; &nbsp; &nbsp; { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;width = 320, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;height = 480, &nbsp; &nbsp; &nbsp; &nbsp; fps = 60, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;scale = "letterBox", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;xAlign = "center", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;yAlign = "center", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;imageSuffix = &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ["@2x"] = 1.5, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ["@4x"] = 3.0, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}, &nbsp; &nbsp; &nbsp; }, &nbsp; &nbsp;} &nbsp; &nbsp; elseif ( string.sub( system.getInfo("model"), 1, 2 ) == "iP" ) then &nbsp; &nbsp;application = &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; content = &nbsp; &nbsp; &nbsp; { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;width = 320, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;height = 480, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fps = 60, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;scale = "letterBox", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;xAlign = "center", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;yAlign = "center", &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;imageSuffix = &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ["@2x"] = 1.5, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ["@4x"] = 3.0, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}, &nbsp; &nbsp; &nbsp; }, &nbsp; &nbsp;} &nbsp; &nbsp; end

And I just create the image like this:

talk\_btn = display.newImage(talk, "talk\_btn.png")

Any ideas why it wouldn’t be picking up talk_btn@2x.png?

Figured it out! I need to use display.newImageRect instead of display.newImage.
