SYNOPSIS
pngtopam [-verbose] [-alpha | -mix] [-background=color] [-gamma=value]
[-text=filename] [-time] [pngfile]
Minimum unique abbreviation of option is acceptable. You may use dou‐
ble hyphens instead of single hyphen to denote options. You may use
white space in place of the equals sign to separate an option name from
its value.
DESCRIPTION
This program is part of Netpbm(1).
pngtopnm was obsoleted by pngtopam(1),introducedwithNetpbm10.44 (Sep‐
tember 2008). pngtopam is backward compatible with pngtopnm, plus adds
many additional functions, including the ability to produce a PAM image
that includes an alpha (transparency) channel.
pngtopnm remains in the Netpbm package because it may have fewer bugs
for now than pngtopam, and may be faster in some environments. Some
day, pngtopnm will probably become an alias for pngtopam.
You can use the pngtopam documentation for pngtopnm, considering the
following differences:
· pngtopnm options are a subset of pngtopam's, as documented
above.
· Any change that the pngtopam manual says happened in or after
Netpbm 10.44 doesn't apply to pngtopnm.
