NAME
       pnmcomp - composite (overlay) two PNM images together

SYNOPSIS
       pnmcomp

       [-align={left|center|right|	beyondleft|beyondright}]     [-valign={top|middle|bottom|
       above|below}]  [-xoff=X]  [-yoff=Y]  [-alpha=alpha-pgmfile]  [-invert]  [-opacity=opacity]
       overlay_file [underlying_file [output_file]]

       Minimum	unique	abbreviation of option is acceptable.  You may use double 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 following 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.
