SYNOPSIS

10       pnmcomp
11
12       [-align={left|center|right| beyondleft|beyondright}] [-valign={top|mid‐
13       dle|bottom| above|below}]  [-xoff=X]  [-yoff=Y]  [-alpha=alpha-pgmfile]
14       [-invert]   [-opacity=opacity]   overlay_file   [underlying_file  [out‐
15       put_file]]
16
17       Minimum unique abbreviation of option is acceptable.  You may use  dou‐
18       ble  hyphens  instead  of single hyphen to denote options.  You may use
19       white space in place of the equals sign to separate an option name from
20       its value.

DESCRIPTION

25       This program is part of Netpbm(1).
26
27       pnmcomp  was  obsoleted  by pamcomp(1),introducedwithNetpbm10.21 (March
28       2004).  pamcomp is backward compatible with  pnmcomp,  plus  adds  many
29       additional  functions, including the ability to process PAM images, and
30       tends to produce better transparency results.
31
32       pnmcomp remains in the Netpbm package because it may  have  fewer  bugs
33       for  now  than  pamcomp,  and is in some environments faster (but newer
34       compilers have been seen to  produce  code  for  pamcomp  significantly
35       faster  than that for pnmcomp).  Some day, pnmcomp will probably become
36       an alias for pamcomp.
37
38       You can use the pamcomp documentation for pnmcomp, considering the fol‐
39       lowing differences:
40
41
42
43       ·      pnmcomp options are a subset of pamcomp's, as
44                   documented above.
45
46       ·      pnmcomp always assumes the input is linear, as pamcomp
47                   does when you specify its -linear option.
48
49       ·      pnmcomp cannot process PAM images.
