How to output multiple image sizes from one design?
I am designing an app for Android and as you may know that Android uses 6 different density buckets from LDPI to XXXHDPI.
Is there a way to save multiple outputs of different sizes from one design using either Photoshop, Illustrator, or another software?
If not will I have to resize it 6 times or is there an easy way?
You can use this script to output all the icons in one shot. It was written for CS6, but should work fine in CC or CC 2014.
Another simple approach would be to record the process as an Action, so you can replay on any image.
Alternatively, with a bit of careful finessing you could use the Generator in CC 2014 to create them.
