Modify PDF Files In Linux With Master PDF Editor

Master PDF Editor is a multi-platform application written in Qt that allows you to create, edit and encrypt PDF and XPS files. The tool can be used to modify or add text, insert images, split, merge or delete pages from PDF files as well as for annotating PDFs, adding sticky notes and much more.

Master PDF Editor is not open source software. The Linux version is free for non-commercial use while the Windows version requires a License ($49.95) after 30 days.

Master PDF Editor features:

  • Change every element of a PDF File;

  • Create new PDF and XPS files or edit existing ones;

  • Add and/or edit bookmarks in PDF files;

  • Encrypt and/or protect PDF files using 128 bit encryption;

  • Convert XPS files into PDF;

  • Add UI controls such as buttons, checkboxes, lists, etc. to PDFs;

  • Highlight text, add sticky notes;

  • Import/export PDF pages into common graphical formats, including BMP, JPG, PNG, and TIFF;

  • Split and Merge PDF files;

  • Move Pages.

In my test, the application was very fast at loading PDF files and I was able to add, remove or change text and images without messing the original PDF formatting (for instance, when importing the same PDF file in LibreOffice Draw, the formatting was messed up).

Download Master PDF Editor

Ubuntu users can install Master PDF Editor by using Ubuntu Software Center: either search for it in Ubuntu Software Center or click the button below to install it:

However, the version available in Ubuntu Software Center is a bit old so if you want to install the latest version, head over to the official Master PDF website to download it - Ubuntu deb file are available.

Arch Linux users can install Master PDF Editor via AUR.

For other Linux distributions, see the Master PDF Editor Linux downloads page - you'll find binaries (RPM and a a generic package) that should work on most Linux distributions.

GNOME Shell Clipboard Extension GPaste 3.8 And 3.3 Available In PPA

GPaste is a clipboard management system that comes with a command line interface as well as a GNOME Shell extension.

The application features URIs (remembers copied files, not just text) and pictures support, option to backup / restore the clipboard history and other useful features.

GPaste 3.3 (for GNOME Shell 3.9.5 and older) and GPaste 3.8 (for GNOME Shell 3.9.90 and newer) were released recently and are now available in the WebUpd8 GNOME 3 PPA.

Changes for GPaste 3.8 (from the previous version available in the PPA):

  • new growing-lines feature - this feature detects if a new copy is an extension of another one and replaces it if that's the case, useful for not polluting your clipboard with variations of the same text;

  • the gnome-shell applet has been totally rewritten and is now more intuitive;

  • the GPaste settings look has been updated to better fit with recent GNOME (GPaste now uses header bars, etc.);

  • new gnome-shell DBus client library;

  • keybinder now uses GNOME Shell if available to grab keys;

  • port to newer glib;

  • preparations for Wayland port;

  • enhanced internal memory management;

  • performance improvements;

  • fixes.

Changes for GPaste 3.3:

  • New growing-lines feature (backported from 3.8)

Install GPaste 3.8 / 3.3 in Ubuntu

The PPA below currently provides:

  • GPaste 3.8 for Ubuntu 14.04 (GNOME Shell 3.10);

  • GPaste 3.3 for Ubuntu 13.10 (GNOME Shell 3.8), Ubuntu 12.10 (GNOME Shell 3.6) and Ubuntu 12.04 (GNOME Shell 3.4).

So, if you're using Ubuntu 13.10 with GNOME Shell 3.10 installed from a PPA, the GPaste version available for your Ubuntu version won't work. But you can manually download (download both gnome-shell-extensions-gpaste and gpaste debs) the GPaste debs from Ubuntu Trusty and install them in Saucy (not tested) and see if that works.

To add the WebUpd8 GNOME 3 PPA and install GPaste, use the following commands:

sudo add-apt-repository ppa:webupd8team/gnome3
sudo apt-get update
sudo apt-get install gnome-shell-extensions-gpaste

Once installed, press ALT + F2 and enter "r" to restart GNOME Shell (or log out and log back in) and then activate GPaste via GNOME Tweak Tool > Extensions.

If you're upgrading from an older GPaste version, run the following command to activate the new features (the command might display an error but that's ok, ignore it):

gpaste dr

Portal 2 Released On Steam For Linux As A Beta

Portal 2, a popular first-person puzzle game developed by Valve, is now available on Steam for Linux, as a beta.

The game, released in April 2011, can be played in single-player campaing or in cooperative campaign (multiplayer) and consists of exploring the Aperture Science Laboratory, a complicated, mechanized maze, and interacting with the environment.

The player must solve puzzles by creating portals connecting two surfaces and the characters can use these portals to move between rooms or to "throw" objects or themselves across a distance.

Below you can watch a Portal 2 Trailer video:

(direct video link)

To install Portal 2 in Steam for Linux, firstly buy the game if you haven't already:

Note that the Steam game product page doesn't yet say the game supports Linux, but it does.

Then, right click the game in Steam for Linux, select Properties and on the BETAS tab, under "Select the beta you would like to opt into" select beta:

Valve hasn't published the Linux system requirements for Portal 2 yet but I've tested it using Intel HD 3000 graphics and it worked pretty well (Ubuntu 14.04). However, you can get an idea on the system requirements by taking a look at the Windows and Mac specifications @ Steam Store.

Portal 2 Beta is available for Linux on Steam and costs 14.99€ to 19.99€ (depends on country) / £14.99 / $19.99.

If you encounter bugs, report them @ GitHub.

Create Classy Slow Motion Videos In Linux With slowmoVideo

slowmoVideo is a Qt application for Linux and Windows that can be used to create beautiful slow motion videos. But don't think all it does is change the video playback speed! The tool can smoothly slow down and speed up the video with optional motion blur.

The application is not new and is actually quite popular, but I just realized I never covered it on WebUpd8, so I though I'd let you know about this cool application, in case you're not familiar with it.

To get an idea on what the application can do, you can watch a video created by the slowmoVideo developer from an image sequence:

Timelapse retiming (slow motion) from Simon A. Eugster.

He explains:

"Source material for this video was an image sequence shot with a Nikon D90. The clouds were moving so quickly that even with shorter intervals (9 seconds; For a different timelapse I used 20 s which was still enough for the clouds there) the video was playing too fast."

Here's another video which has only some parts in slow motion:

Short dream – Hair in slow-motion from Simon A. Eugster

slowmoVideo features:

  • can be used with any video format supported by ffmpeg;

  • supports loading image sequences;

  • motion blur can be added to the videos.

As you can see, the application doesn't offer a huge amount of features and instead it's specialized on doing one thing only: creating amazing slow motion videos from your footage.

slowmoVideo isn't exactly intuitive, but the documentation available on its website should be enough to get you started. You'll find it HERE.

One note though: I recommend trimming your video before importing it into slowmoVideo because it extracts frames from the video when importing it and that will take a long time if your video is relatively large.

Install slowmoVideo in Ubuntu

slowmoVideo can be installed in Ubuntu by using its official PPA (there are no packages for Ubuntu 14.04 yet!). To add the PPA and install slowmoVideo, use the commands below:

sudo add-apt-repository ppa:brousselle/slowmovideo
sudo apt-get update
sudo apt-get install slowmovideo

Download slowmoVideo

Arch Linux users can install slowmoVideo via AUR.

Download slowmoVideo (for Windows or source files). The downloads page includes build instructions for Debian/Ubuntu, Fedora, and openSUSE.
