RC2 - Export slice layer options x1 x2 x3 explained

[DM1]

If I draw a 32x32 pixel image and export as png with Standard option x1, then reopen the slice, the size is reduced  16x16px? 
If I export the 32x32 px slice as retina x2 then reopen it, the size is 32x32px. Is this correct behaviour and if so why? 🙂

Hi DM1,
 

This is intentional behaviour (although I'm not personally a fan of it).

Because your document is set to 144 DPI the Export Persona automatically creates half size exports when outputting to 1x format, the correct size when outputting at 2x, and double size when out putting at 3x. If you work at 288dpi, then your document will export at the correct size when using 3x, half size then using 2x and then half that when using 1x.

If you work at any other DPI other than those 2 then you should be ok!

Thanks Sean for explaining why it behaves the way it does.

It's simply because, if you used a preset of an iPad, for example, you could preview while you work at retina or standard pixels and then when you output at 1x or 2x you got the thing you were seeing while you were designing.
