pnmcomp - composite (overlay) two PNM images together

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.

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:

• *pnmcomp*/ options are a subset of pamcomp’s, as/ documented above.
• pnmcomp*/ always assumes the input is linear, as /*pamcomp does when you specify its *-linear*/ option./
• *pnmcomp*/ cannot process PAM images./
