NAME
pnmcomp - composite (overlay) two PNM images together
SYNOPSIS
pnmcomp
[-align={left|center|right| beyondleft|beyondright}] [-valign={top|mid-
dle|bottom| above|below}] [-xoff=X] [-yoff=Y] [-alpha=alpha-pgmfile]
[-invert] [-opacity=opacity] overlay_file [underlying_file [out-
put_file]]
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)
pnmcomp was obsoleted by pamcomp(1) , introduced with Netpbm 10.21
(March 2004). pamcomp is backward compatible with pnmcomp, plus adds
many additional functions, including the ability to process PAM images,
and tends to produce better transparency results.
pnmcomp remains in the Netpbm package because it may have fewer bugs
for now than pamcomp, and is in some environments faster (but newer
compilers have been seen to produce code for pamcomp significantly
faster than that for pnmcomp). Some day, pnmcomp will probably become
an alias for pamcomp.
You can use the pamcomp documentation for pnmcomp, considering the fol-
lowing differences:
o pnmcomp options are a subset of pamcomp's, as
documented above.
o pnmcomp always assumes the input is linear, as pamcomp
does when you specify its -linear option.
o pnmcomp cannot process PAM images.
