Now available for testing is the PDF import extension, which also includes hybrid PDF-ODF export. PDFs are designed for layout instead of for further editing, so when a word processor, spreadsheet, or presentation application exports to a PDF, the layout and document structure are lost. To avoid disappointment, you must keep in mind creating a PDF is not a reversible process because of the limitations of PDF as a format.

To install the extension is simple.  Grab it here. And simply install it by going to Tools –> Extension Manager –> Highlight My Extensions –> Hit the Add button, locate the extension and voila.

The import process takes a long time compared to opening an OpenOffice.org document because of the necessary guesswork caused by the limitations of PDF.

ImageMagick is a powerful command line image processing package with a number of features you could install it using the following command :

sudo apt-get install imagemagick or sudo yum install imagemagick

After installation is over to convert say sample.pdf to sample.png issue the following command

convert sample.pdf sample.png

convert sample.pdf sample.jpg

Now if sample.pdf has multiple pages ImageMagick would convert each individual page into a separate file for example : 1st page as sample-0.png , 2nd page as sample-1.png and so on .

fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.
