Inconsistent documentation at http://www.imagemagick.org/Usage/formats/#png_write in comparison to http://www.imagemagick.org/script/comma ... hp?#define

In the former, the = sign is missing.

Also just as example, I have not been able to force other than 8/1-bit or 16/1-bit for

convert -size xc:'#00000000' -define -define png:depth=32 result.png
convert -size xc:'#00000000' -define -define png:depth=32 PNG32:result.png

convert -size xc:'#00000000' -define png:color-type=6 result.png
convert -size xc:'#00000000' -define png:color-type=6 PNG32:result.png


Always show 1-bit version. Don't know if this should show 16-bit values for Q16. Perhaps I misunderstand, maybe it is showing 16 bit values as they are still zero no matter what.

I am on Mac OSX Tiger IM 6.5.5-1 Q16 HDRI

Sorry for the HDRI right now.

Fixed the former!

Sorry can't do anything about the later.

thanks, Anthony.

New things I had not seen before and was trying to answer a user's questions and could not get it to work.
