Exporting upsized pngs lose transparancy

[lindsay.ragsdale]

I am trying to upsize a png in Gigapixel 8.0.1 and it is adding a white background along with significant artifacts. Another member on my team is experiencing same problem. Bit depth, color space, output format all preserved/set correctly. When changing output format from preserve original to png, results in same unwanted background.

Any ideas?

It looks like a transparency layer issue. Topaz doesn’t preserve the alpha info properly.

If you can create the equivalent image without an alpha layer it should enlarge properly.
