ICNS at a glance
ICNS
ICNS reflects the Mac graphics-resource tradition where a single icon asset is really a packaged set of representations for one application or object identity.
DDS at a glance
DDS
DDS grew out of Microsoft's graphics API and game-development ecosystem, which is why it feels more like an engine or texture-delivery format than a conventional consumer image file.
