How do I Create iPhone 6+ Screenshots without a Mac

Hi Folks,

When using the Intel XDK for an iOS build, how do you generate the iPhone 6 and 6+ screenshots? (1242x2208 and 750x1334)

I have been exporting to Ejecta/Xcode and using the simulator, but if you don't have a Mac, how do you do it?

I'm wondering if there is an easier way without a Mac?

Thanks,

Alan

Resize it in a photo editor (or Photoshop if you own that)

Of course, but you loose a lot of crispness and detail doing that.
