iOS graphics need more than 72 dpi

Hi Jason,

Can you pass on that declare structure for determining the iOS device scale factor?

Cheers

The link to the declare page that shows the scale factor doesn’t show the info. It tried searching but couldn’t come up with it, can you help?

Is it this Declare?

I put the scale factor declare (slightly modernized to use iOSScreen) here:

Pixelcolor Path

ScaleFactor is a property of UIScreen which should be iOSScreen in Xojo. Try Declare function getScale lib UIKit selector "scale" (id as ptr) as CGFloat And in your call to CGImage dim newUIImage as ptr = imageWithCGImage(NSClassFromString(“UIImage”), cgimageref, getScale(App.CurrentScreen.handle), 0) Other values for orientation are (upside)down = 1, left = 2, right = 3

Thanks Paul that does the trick
