Re: [htdig] Indexing large Powerpoints

[David A. <D.J...@so...>]

How are you using htdig to index .ppt files?  Recent versions of doc2html=
.pl=20
have a default input limit of 20Mbytes and will not try to convert files =
any=20
larger.  Just increase the limit in the doc2html.pl script.

I have found that ppthtml 0.4 from www.xlhtml.org (now relocated to=20
http://chicago.sourceforge.net/xlhtml), which is what I use, does not alw=
ays=20
succeed in extracting text after the first embedded image.

I have not found problems with ppthtml on RedHat Linux, but on Solaris th=
e=20
process size could be very large.  With >20Mbytes .ppt files I doubt if i=
t=20
would run.
