PNG with transparent background

Hi!

I need to export an image in PNG format, so that a developer uses it in order to apply rounded corners and border to a dialog, using the 9-slice technique 9-slice scaling - Wikipedia
He needs a transparent background, though, which I can´t export from Antetype, because the background is white, despite adjusting a transparency of 0%.

Or is there a way to do it? If not, this would be a feature request.

9 slice

Thanks in advance!

Unfortunately, we do not currently support the export of transparent pngs. But you can use Safari to do that. Open Developer Tools, right click on the cell you want to export and choose capture screenshot.
