Helper script to generate NativeScript image resources for both Android and iOS from an image.

Executing the script with an image path as parameter, it will generate all the necessary image sizes and automatically populate the app/App_Resouces directory tree.

Install the script:

$ sudo cp nsresgen.sh /usr/local/bin/nsresgen

And invoke it while inside the root directory of a NativeScript project, passing an image as parameter:

$ nsresgen /home/user/cats/image.png

The app/App_Resources directory will be correctly populated, so you're now able to use the resource from your code as usual:

<Image src="res://image"></Image>

The nsresgen script depends upon the imagemagick package, so be sure to have it in your system.
