Collect
RESONATOR collects all the design elements from all of your project's screens (icons, buttons, UI controls, etc.) into a single Res-Project.psd. Additionally, all of the elements are collected in the densities you need, so you can quickly fix “blurry” graphics and other defects that arise during resizing.

If you want to save your element as .9.png, put special layers named “.content” and “.stretch” in the current folder with “~”. The “.content” layer determines the location of content within the element (the rightmost and bottommost black single-pixel lines); the “.stretch” determines how the element will stretch (the leftmost and topmost black single-pixel lines). Here's a short video: https://youtu.be/qwABM64Nvpc...S8uTpb0ZPkRBEm1_6t2AN2JVmThy that shows an example of how this works.

Export
RESONATOR exports all design elements with file names and a folder structure that are “correct” for developers. And it works for any platform: Android, iOS, Retina Web, and even Windows Phone :-)

RESONATOR will arrange resource files using a naming convention and folder structure that is “correct” for developers.

For example, for Android RESONATOR creates subfolders named “drawable-xxhdpi”, “drawable-xhdpi”, etc. and places files in them. For iOS RESONATOR adds the prefix “@2x” or “@3x” to your names, as needed.

Store
RESONATOR stores all the design elements you draw and transfers them to developers in a single file. This means no more "slices" in separate files and no more endlessly searching for them when you need to fix something.
