When designing for a retina website in Xd, should you use a custom artboard and design at 2732x 1536 (1366 x 768 @x2) and then export choosing "Designed at 2x"
I assume this them creates assets at 100% size and half size?
Whereas if you designed at 1366 x 768 and exported at "designed at 1x" it creates 100% and double size? is that right?
Done my own testing and this appears to be the case, I was concerned that designing at 1366x768 and exporting at "designed at 1x" would upscale any none vector content but it looks like as long as the original image is large enough then it doesn't upscale
Oops! This one slipped through the cracks. This is right - designed at 1x means that it'll create the other sizes (depending on whether you're exporting for web, iOS, or Android). The only exception to this is SVG, which only exports one size.
Glad you got it worked out!
