I used a DOS port of wvware to extract the png from a doc file that 
consists only of one embedded png, produced by a scanner.

Viewed with less, the png file starts with <89>PNG.  The doc file has a 
lot of <FF) and @^ and then <89>PNG.  At the end it has more <FF> and @^ 
and then something about WORD.

I could probably just use a text editor to manually chop off the beginning 
and end of this sort of doc file instead of wvware, but can someone 
suggest a script which would delete all characters before <89>PNG

The png file ends with IEND<AE>B`<82>.  The WORD file continues with many 
pages of @^ (to encourage you to get a larger hard drive?) and <FF> and 
then the names of the two people working at that office repeatedly, some 
comments on what is in the document that they probably added, and various 
mentions of Microsoft Word 9.0.  So I could also just chop that off.

<82> is presumably a hex character and perhaps a shell script would need 
to refer to it differently.  Pico shows a file starting in a small dark 
box and ending in this same box plus Spanish upside-down question mark.
I included the IEND in case the <AE>etc. part occurred elsewhere.

Antiword does fine with text WORD files so the above could for my purposes 
substitute for wvware and be a lot smaller.  (Like pbmtolj instead of gs 
to print my own scanner output).  It would also be library independent.

It would not be difficult to edit one file manually with e3 or pico but 
people send me collections of them.

This would be a handy script to use with netpbm instead of wvware.
