16 bit PNG

Post by mdfisher272 »

I don't see any support for 16bit per channel PNG files. Is this not supported?

In writing.
Isnt RAW like in NEF for Nikons a 16bit format?
But many GUI like the first CS-Photoshops do not "understand" RAW like NEF.
Converting to 16bit formats like PNG 16bit would be very valuable for XnViewMP or XnConvert
in making the workflow much easier when "developing" NEF-files.

But the newest XnViewMP 0.68 does not have any Batch Convert - Options
to get all 16bit from RAW to a useful 16bit format compatible with PS or GIMP.

XnViewMP use 8bits as internal format, so 16bits is only supported as reading
