Corona SDK Pro Tip of the Day #15
Automatic image downsizing
Use a special script to make lower res image versions. @4x -> @2x -> 1x version.
It takes time to manually save scaled down versions of your original artwork. If you support iPad retina, your original is @4x version, otherwise it's @2x version.
So I've made a script that uses bash and ImageMagick to find and scale down all high res versions into lower res versions.
Grab it here.
Save it in say
/usr/bin, apply execution bit with
chmod +x and use it like this
your/project/directory> downsize.sh png
your/project/directory> downsize.sh jpg
That will find recursively all
jpg images in your project and prepare lower res versions for them.
