Image scaling on iPhone4s

Getting Started Newbie Questions
#1

I am using several newImage calls in my code and all works fine on sim Android and iPad2 but on iPhone 4s the scaling goes to pot!
backing=display.newImage(“app-backing.png”)

This is fine and works fine on all except iPhone4s

Any clues? [import]uid: 40581 topic_id: 25624 reply_id: 325624[/import]

More info would be useful here (image size, config setup, etc.) but have you tried using newImageRect? :slight_smile: [import]uid: 52491 topic_id: 25624 reply_id: 103607[/import]

Could this be related to the auto-scaling that is done if the image is larger than the device’s screen? If your image is bigger than the device screen, you need to add TRUE to your newimage call.

 backing=display.newImage("app-backing.png",true)

This is explained on the newimage reference page.

isFullResolution
boolean: To override autoscaling and show the image at its full-resolution, use the optional isFullResolution parameter. By default, it is false, but if you specify true, then the new image is loaded at its full resolution (maximum of 2048 x 2048). [import]uid: 56820 topic_id: 25624 reply_id: 103611[/import]
