and hello <span>Pankaj,<br>

I would be willing to mentor you on getting a PDF-Import filter
for Calligra Words done. I am available in our irc-channel
#calligra (on <a>irc://irc.freenode.net/calligra</a> - use e.g. the
"Konversation" application to connect to IRC) as "sebsauer".<br>
<br>
First steps would be;<br>
1. Build Calligra yourself from the sources. See
<a href="http://community.kde.org/Calligra/Building" target="_blank">http://community.kde.org/Calligra/Building</a><br>
2. Get a KDE git-account to commit work you do. See
<a href="http://techbase.kde.org/Contribute/Get_a_Contributor_Account" target="_blank">http://techbase.kde.org/Contribute/Get_a_Contributor_Account</a><br>
3. Get familar with the area where the work will happen. That is
the filter-framework. We are going to write a filter-plugin that
reads PDF-files using the poppler library and then generating
OpenDocument ODF. The filter-framework will take care of all the
things around including passing the resulting ODT-file on to
Calligra Words so it's loaded+displayed and the user can
edit+save.<br>
<br>
For point 3 you may like to have a look at;<br>
* in our sources at the Text-file importer located at
calligra/filters/words/ascii/AsciiImport.cpp to have an idea how a
filter looks like.<br>
* at the poppler-library. For that install libpoppler (if not
already installed cause it's a pretty standard-library used by
applications like Okular to display PDF-files). There look at the
header-files to have an idea how the API looks like.<br>
<br>
Once those initial steps are done we would create an initial
filter skeleton for the PDF-import filter. We could basically copy
the AsciiFilter linked above over and 1) change the CMakeLists.txt
to link against libpoppler and 2) change the desktop file so we
take PDF-files as input and not text-files like the text-filter
does and 3) start to use the libpoppler-API to evaluate the
PDF-document.<br>
<br>
So much for the start :-)<br>
