"High-resolution versions of all of the graphics that make up the built-in web controls are now automatically included with your built apps."
Quoting from here:
Yes, but how?
I would like to have some buttons in a webproject, which change color when dragging over or clicking it.
I figured I would use a webcanvas and add some pictures to the project and make use of them in the paint eventhandler of the webcanvas.
But how exactly do I make sure that a HiRes picture is loaded on Retina and lowRes on a standard screen?
"Multi-resolution Images are now available in Web Projects. Just like iOS and Desktop projects, you can now drag in multiple representations of the same image and the Web Framework will automatically deliver the correct version to the browser."
I guess there are some naming conventions to respect, in order to make this work?
Where is this documented? Is there a sample project?
