Images for Retina Display

Hey Stone Preston Matthew Mascioni Kevin Lozandier Sarah Parmenter ,

When using images.assets folder, it is indicated that one should use an image in two sizes.

If I only upload the 2x image for retina displays, does a non-retina device then automatically render the 2x image as a normal/1x image? I already made sure that the 2x image is an even number, so that it can be divided by 2. Or do I have to manually make both an 1x and a 2x image for each image I use in the app?

Thanks a lot!

Cheers, pascal

You have to manually make both 1x and 2x images for each image that you use in the app. This is simple in Sketch, however - makes it easy to do this in two easy exports. Simply export all your assets at @2x then run it again at regular size.

Only the @2x artwork needs to have @2x on the end of it. For example. If you had a file titled "logo". It would render like this: logo.png logo@2x.png

Hope that helps!
