NOTE: As from Titanium 5.0 you only need one DefaultIcon.png for iOS. Windows support has been added in Titanium 5.1. Use the new Titanium SDK Version option to generate the right icons for your project.

Generate Icons & Splash (Launch) Images

For Appcelerator® Titanium™ & Alloy

Icons

You could generate all icons from a single 2048x2048 PNG. Set Border radius to 10 when you do. It is more likely you want to run it once for iOS using a flat image and then again for the other platforms using a transparent image for unique shapes.

Splashes

You could use the same flat square 2208x2208 PNG for both icons and splashes. Set Border radius to 10 and disable Crop It is more likely you run it one (or two) times for icons and one time for splashes, or two if you want a perfect nine-patch for Android and provide a croppable input for the other platforms.

Assets

You can now also generate image assets. Simply upload any image and specify its density under the Assets tab or let it autodetect if the input filename has @2x or @3x .

Compression

Thanks to device fragmentation icons & splashes make a big part of your app's size. Use ImageOptim to reduce the size up to 50%. Just drop your entire project on the app and get a coffeee while it melts your laptop.
