Hi-Res Images at Natural Size?

Scott,

I think this is only achievable using density mapped images, I’d guess you already understand the process, but I just used this lesson to remind myself…

http://lessons.livecode.com/m/15262/l/156530-how-do-i-support-different-device-screen-densities

I tried a quick test and it looks like you do need to use a referenced image and a high resolution version with the name format <image>@2x.<ext> or <image>@extra-high.<ext>

Having read what it says about ‘Device Resolution’ at the end of the lesson, I would have thought setting the 'useDeviceResolution' of the stack to true would do the trick, but it doesn’t seem to affect images, at least not in my limited tests.

HTH

Paul
