      Can’t look at this right now, but I’ll note that the byteOrder flags refer to the byte order of each *component*, so for a 16-bit PNG, you’d like have something like .byteOrder16Little. Note that your alpha is also likely .premultipliedLast rather than .last.

      so byteOrder32Little is so each color channel is 32-bit?? Is that even possible? And for normal 8-bit channels?

      No, it’s dependent on the bpc value as well. Sorry; should’ve clarified that up-front. An excerpt from Gelphman ‘06:pic.twitter.com/pjyC1h3S7a
