Re: What software do you use to open chm and pdf format file
Chmlib:
h**p://66.93.236.84/~jedwin/projects/chmlib/
"CHMLIB is a library for dealing with Microsoft ITSS/CHM format files. Right now, it is a very simple library, but sufficient for dealing with all of the .chm files I've come across. Due to the fairly well-designed indexing built into this particular file format, even a small library is able to gain reasonably good performance indexing into ITSS archives. Since the last version there have been major bugfixes, portability improvements, and minor feature additions. Code now runs on Linux, Windows, Solaris, and Irix. 0.31 includes some last minute bug fixes from Andrew Hodgetts which I haven't got time to test tonight. Download it, instead of 0.3, if you are running into problems. The bugfixes included some more portability issues for Solaris, and a problem that caused extract_chmLib to fail on certain files."
XChm:
h**p://xchm.sourceforge.net/
"xCHM is a .chm viewer for UNIX (Linux, *BSD, Solaris), written by Razvan Cojocaru.
Success stories of xCHM on Mac OS X have also been received, and apparently xCHM even works if compiled under the Cygwin environment in Windows.
xCHM can show the contents tree if one is available, print the displayed page, change fonts faces and size, work with bookmarks, do the usual history stunts (forward, back, home), provide a searchable index and seach for text in the whole book. The search is a fast B-tree search, based on the internal $FIftiMain file found inside indexed .chm archives, and it can be customized to search in content or just the topics' titles."
xCHM uses chmlib
Archmage:
h**p://archmage.sourceforge.net/
"This is the page for arCHMage - extensible reader/decompiler of files in CHM format(Microsoft HTML help, also known as Compiled HTML).
arCHMage is based on chmlib by Jed Wing (h**p://66.93.236.84/~jedwin/projects/chmlib/) and is written on python"
NOTE: If you use either arCHMage or xCHM, you need to install chmllib first. I'm currently using xCHM and it works fine (no problems). As for PDF files, just use gpdf or konqueror.
