DESCRIPTION
This program is part of Netpbm.
pnmscale was obsoleted by pamscale, introduced with Netpbm
10.20 (January
2004). pamscale is backward compatible with pnmscale, plus
adds many
additional functions, including the ability to process PAM im-
ages, and tends
to produce better results.
pnmscale remains in the current Netpbm package because it
probably has fewer
bugs for now than pamscale, and may have superior
performance
characteristics in some cases. Some day, pnmscale will proba-
bly become an
alias for pamscale.
You can use the pamscale documentation for pnmscale, consid-
ering the
following differences:
* pnmscale options are a subset of pamscale's, as documented
above.
* pnmscale always assumes the input is linear, as pamscale
does when you
specify its -linear option.
* pnmscale cannot process PAM images.
