The desire of this proposal is to make a system that works with a minimal number of assets and a minimal syntax. It retains pixel crispness when possible, but still presents a usably sized display on all devices. It also optionally allows for using multiple images to get better clarity on multiple devices when a project can afford to produce multiple assets.
A user creates a single image.png
file and should be able to use this in the interface like this:
<Image ux:File="image.png"/>
This should work across all devices, that is ones with different screen densities. It won't be significantly larger or smaller if the target screen density differs. It produces a predictable UI layout.
