Under the Hood
It essentially takes your GUI input and turns it into the following Ghostscript command:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.6 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=[compressed.pdf] "[input.pdf]"
Currently, if any of the below conditions are met, the application will either automatically handle or show an error/warning dialog message that returns to the main window without doing anything upon the user clicking “OK”. This is designed to prevent any dangerous execution of Ghostscript. For the ones that are questionable, it will warn the user and provide a chance to cancel or confirm.
- Output file name was not specified, use “compressed.pdf” by default
Shows an Error Dialog Message and Returns to Main Window Upon the User Clicking “OK”:
- Input file is not specified
- Input file does not end with .pdf
- Input File and Output File are the same
- Input File Name Contains Unsupported Characters(\/:;)
- Output File Name Contains Unsupported Characters(\/:;)
Questionable Conditions that the application will verify with User via A Dialog Message:
- Output File does not end with .pdf, verify with user that’s really what they want
- Output File Name Matches a File in the Output Directory
Download and place “Densify” folder in /opt
Execute the install.sh script to install this application:
cd /opt/Densify/ sudo chmod 755 install.sh sudo ./install.sh
Enter your sudo password when the dialog pops up.
You should then see this:
[email protected]:/opt/Densify$ sudo ./install.sh Installation Complete. If you don't see any errors above, you are good to go! :) [email protected]:/opt/Densify$
Now, you can search for “densify” in Gnome Shell Search and you will see that Densify is available to launch. Enjoy!
