I have uploaded fresh versions of npng.c and npng.1 to
/n/sources/contrib/lucio/pub/ for further testing.

The fix recommended by Russ is in there (=CE=B1 premultiplication) as wel=
l
as some (re-)implementation of options.  Other than -v (RGBV or CMAP8)
output, which looks pretty awful on small icons, it all seems to work
at least as well as png(1).  The -e option has me bothered, still.
8.npng is for those who seriously need the executable for the 386.

What I have not yet fixed is the use of sysfatal() for error
reporting, I need to change its name as well as its behaviour.  The
README file has not been updated either.

I have a slightly OT question: is it reasonable that PNG versions of
an image may be bigger than their GIF equivalent and (less
sursprisingly) much bigger than their JPEG versions?  I have not
tested this theory, but I have had this reported to me.
