   What is Pympress?
       Pympress  is a PDF presentation tool designed for dual-screen setups such as presentations
       and public talks.  Highly configurable, fully-featured, and portable

       It comes with many great features (more below):

       • supports embedded gifs (out of the box), videos,  and  audios  (with  VLC  or  Gstreamer
         integration)

       • text annotations displayed in the presenter window

       • natively supports beamer's notes on second screen, as well as Libreoffice notes pages!

       Pympress is a free software, distributed under the terms of the GPL license (version 2 or,
       at your option, any later version).

       Pympress was originally created and maintained by Schnouki, on his repo.

   Installing
       • Ubuntu 20.04 focal or newer, Debian 11 Bullseye or newer (maintained by @mans0954)

            apt-get install pympress libgtk-3-0 libpoppler-glib8 libcairo2 python3-gi python3-gi-cairo gobject-introspection libgirepository-1.0-1 gir1.2-gtk-3.0 gir1.2-poppler-0.18

       • RPM-based Linux (Fedora, CentOS, Mageia, OpenSuse, RHEL)

         You can get pympress from the pympress COPR repo of your system.

         With yum or dnf, simply do:

            dnf copr enable cimbali/pympress
            dnf install python3-pympress

         With zypper, fetch the link of the .repo in the table at the bottom of the COPR page and
         add it as a source.

            zypper addrepo https://copr.fedorainfracloud.org/coprs/cimbali/pympress/repo/opensuse-tumbleweed/cimbali-pympress-opensuse-tumbleweed.repo
            zypper install python3-pympress

       • Arch Linux from AUR (maintained by @Jose1711)

            git clone https://aur.archlinux.org/python-pympress.git
            cd python-pympress
            makepkg -si
            pacman -S poppler-glib  # dependency temporarily missing from AUR package

         Or using any other tool to manage AUR packages (yay, pacaur, etc.):

            yay -S python-pympress
            pacman -S poppler-glib  # dependency temporarily missing from AUR package

       • macOS using Homebrew

            brew install pympress

       • Windows with Chocolatey (maintained by @ComFreek)

            choco install pympress

         Or download the latest installer from the latest Github release.

         • If  you  get  an  error  message along the lines of "MSVCP100.dll is missing", get the
           Visual C++ 2010 redistributables from Microsoft (x86  (32  bit)  or  x64  (64  bits)).
           Those libraries really should already be installed on your system.

       • Other  systems,  directly from PyPI  − requires python, gtk+3, poppler, and their python
         bindings:

            python3 -m pip install "pympress"

         • Make sure you have all  the  dependencies.  (These  are  already  included  in  binary
           packages or their dependencies.)

         • Using  pip,  you may want to install with the --user option, or install from github or
           downloaded sources.  See the python documentation on installing.

         • If your python environment lacks the Gobject Introspections module, try

           1. using --system-site-packages for virtual environments,

           2. installing pygobject from pip (pip install pygobject, which  requires  the  correct
              development/header  packages.   See the PyPI installation instructions of PyGObject
              for your system).

   Notes
       To support playing embedded videos in the PDFs, your system must have VLC installed  (with
       the  same bitness as pympress).  VLC is not distributed with pympress, but it is certainly
       available in your system’s package manager and on their website.

   Usage
   Opening a file
       Simply start Pympress and it will ask you what file you want to open.  You can also  start
       pympress from the command line with a file to open like so: pympress slides.pdf or python3
       -m pympress slides.pdf

   Functionalities
       All functionalities are available from the menus of the window with slide previews.  Don't
       be afraid to experiment with them!

       Keyboard  shortcuts  are  also  listed in these menus. Some more usual shortcuts are often
       available, for example Ctrl+L, and F11 also toggle fullscreen, though the main shortcut is
       just F.

       A few of the fancier functionalities are listed here:

       • Two-screen  display:  See  on  your laptop or tablet display the current slide, the next
         slide, the talk time and wall-clock  time,  and  annotations  (either  PDF  annotations,
         beamer  notes  on second slide, or Libreoffice notes pages).  The position of the beamer
         or Libreoffice notes in the slide is detected automatically and can be overridden via  a
         menu option.

       • Media support: supports playing video, audio, and gif files embedded in (or linked from)
         the PDF file.

       • Highlight mode: Allows one to draw freehand on the slide currently on screen.

       • Go To Slide: To jump to a selected slide without flashing through the whole presentation
         on  the  projector,  press G or click the "current  slide" box.  Using J or clicking the
         slide label will allow you to navigate slide labels instead of page numbers, useful e.g.
         for multi-page slides from beamer \pause.

         A  spin  box  will  appear,  and you will be able to navigate through your slides in the
         presenter window only by scrolling your mouse, with the Home/Up/Down/End keys, with  the
         +  and  - buttons of the spin box, or simply by typing in the number of the slide. Press
         Enter to validate going to the new slide or Esc to cancel.

       • Software pointer: Clicking on the slide (in either window) while holding ctrl down  will
         display  a  software laser pointer on the slide. Or press L to permanently switch on the
         laser pointer.

       • Talk time breakdown: The Presentation > Timing Breakdown menu item displays a  breakdown
         of  how  much  time  was  spent  on  each  slide,  with  a  hierarchical  breakdown  per
         chapters/sections/etc. if available in the PDF.

       • Automatic file reloading: If the file is modified, pympress will reload it (and preserve
         the current slide, current time, etc.)

       • Big button mode: Add big buttons (duh) for touch displays.

       • Swap screens: If Pympress mixed up which screen is the projector and which is not, press
         SEstimated talk time: Click the Time estimation box and set your planned  talk  duration.
         The color will allow you to see at a glance how much time you have left.

       • Adjust screen centering: If your slides' form factor doesn't fit the projectors' and you
         don't want the slide centered in the window, use  the  "Screen  Center"  option  in  the
         "Presentation" menu.

       • Resize  Current/Next  slide:  You  can drag the bar between both slides on the Presenter
         window to adjust their relative sizes to your liking.

       • Preferences: Some of your choices are saved in a configuration file,  and  more  options
         are accessible there. See the configuration file documentation for more details.

       • Caching:  For efficiency, Pympress caches rendered pages (up to 200 by default). If this
         is too memory consuming for you, you can change this number in the configuration file.

       • Configurability: Layout of presenter window dynamically configurable, with 1 to 16  next
         slides preview

       • Editable  PDF  annotations:  Annotations  can  be  added,  removed,  or changed, and the
         modified PDF files can be saved

       • Automatic next slide and looping

   Command line arguments-h, --help: Shows a list of all command line arguments.

       • -t mm[:ss], --talk-time=mm[:ss]: The estimated  (intended)  talk  time  in  minutes  and
         optionally seconds.

       • -n  position,  --notes=position:  Set the position of notes on the pdf page (none, left,
         right, top, or bottom). Overrides the detection from the file.

       • --log=level: Set level of verbosity in log file (DEBUG, INFO, WARNING, ERROR).

   Media and autoplay
       To enable media playback, you need to have either:

       • Gstreamer installed (enabled by default), with plugins  gstreamer-good/-bad/-ugly  based
         on which codecs you need, or

       • VLC  installed (and the python-vlc module), with enabled = on under the [vlc] section of
         your config file.

       To produce PDFs with media inclusion, the ideal  method  is  to  use  beamer’s  multimedia
       package, always with \movie:

          \documentclass{beamer}
          \usepackage{multimedia}

          \begin{frame}{Just a mp4 here}
              \centering
              \movie[width=0.3\textwidth]{\includegraphics[width=0.9\textwidth]{frame1.png}}{movie.mp4}

              \movie[width=0.3\textwidth]{}{animation.gif}

              \movie[width=0.3\textwidth]{}{ding.ogg}
          \end{frame}

       If  you desire autoplay, ensure you have pympress ≥ 1.7.0 and poppler ≥ 21.04, and use the
       movie15 package as follows:

          \documentclass{beamer}
          \usepackage{movie15}
          \begin{document}

          \begin{frame}
            \begin{center}
              \includemovie[attach=false,autoplay,text={%
                  \includegraphics{files/mailto.png}%
                }]{0.4\linewidth}{0.3\linewidth}{files/random.mpg}
            \end{center}
          \end{frame}

          \end{document}

   Dependencies
       Pympress relies on:

       • Python (version ≥ 3.4, python 2.7 is supported only until pympress 1.5.1, and 3.x <  3.4
         until v1.6.4).

       • Poppler, the PDF rendering library.

       • Gtk+  3,  a  toolkit  for  creating  graphical  user  interfaces,  and its dependencies,
         specifically:

         • Cairo (and python  bindings  for  cairo),  the  graphics  library  which  is  used  to
           pre-render and draw over PDF pages.

         • Gdk, a lower-level graphics library to handle icons.

       • PyGi, the python bindings for Gtk+3. PyGi is also known as pygobject3, just pygobject or
         python3-gi.

         • Introspection bindings for poppler may be shipped separately, ensure you have those as
           well (typelib-1_0-Poppler-0_18 on OpenSUSE, gir1.2-poppler-0.18 on Ubuntu)

       • optionally  VLC,  to  play  videos  (with the same bitness as Python) and the python-vlc
         bindings.

       • optionally Gstreamer to play videos (which is a Gtk library)

   On linux platforms
       The dependencies are often installed by default, or easily available through your  package
       or  software  manager.   For example, on ubuntu, you can run the following as root to make
       sure you have all the prerequisites assuming you use python3:

          apt-get install python3 python3-pip libgtk-3-0 libpoppler-glib8 libcairo2 python3-gi python3-cairo python3-gi-cairo gobject-introspection libgirepository-1.0-1 libgirepository1.0-dev gir1.2-gtk-3.0 gir1.2-poppler-0.18

       Different distributions might have different package naming conventions, for  example  the
       equivalent on OpenSUSE would be:

          zypper install python3 python3-pip libgtk-3-0 libpoppler-glib8 libcairo2 python3-gobject python3-gobject-Gdk python3-cairo python3-gobject-cairo typelib-1_0-GdkPixbuf-2_0 typelib-1_0-Gtk-3_0 typelib-1_0-Poppler-0_18

       On CentOS/RHEL/Fedora the dependencies would be:

          yum install python36 python3-pip gtk3 poppler-glib cairo gdk-pixbuf2 python3-gobject python3-cairo

       And on Arch Linux:

          pacman -S --needed python python-pip gtk3 poppler cairo gobject-introspection poppler-glib python-gobject

   On macOS
       Dependencies can be installed using Homebrew:

          brew install --only-dependencies pympress

   On windows
       The binary installer for windows comes with pympress and all its dependencies packaged.

       Alternately,  in  order to install from pypi or from source on windows, there are two ways
       to get the dependencies:

       1. using MSYS2 (replace x86_64 with i686 if you're using a 32 bit machine).

          Warning: this can take a substantial amount of disk size as it requires a full software
          distribution and building platform.

             pacman -S --needed mingw-w64-x86_64-gtk3 mingw-w64-x86_64-cairo mingw-w64-x86_64-poppler mingw-w64-x86_64-python3 mingw-w64-x86_64-vlc python3-pip mingw-w64-x86_64-python3-pip mingw-w64-x86_64-python3-gobject mingw-w64-x86_64-python3-cairo

          This is also the strategy used to automate builds on appveyor.

       2. Using  PyGobjectWin32. Be sure to check the supported Python versions (up to 3.4 at the
          time of writing), they appear in the FEATURES list in the linked page.

       • Install native python for windows

       • Get GTK+3, Poppler and their python bindings by executing the PyGi installer.   Be  sure
         to tick all the necessary dependencies in the installer (Poppler, Cairo, Gdk-Pixbuf).

       Alternately, you can build your Gtk+3 stack from source using MSVC, see the Gnome wiki and
       this python script that compiles the whole Gtk+3 stack.  This strategy has not  been  used
       successfully  yet,  due  to problems building Poppler with its introspection bidings (i.e.
       typelib) − see #109.

   Packages
       Official releases are made to PyPI and with github releases.  The  community  maintains  a
       number  of  other  packages  or  recipes  to  install  pympress (see Install section). Any
       additions welcome.

   Configuration file
       Pympress has a number of options available from its configuration file.

       This file is usually located in:

       • ~/.config/pympress on Linux,

       • %APPDATA%/pympress.ini on Windows,

       • ~/Library/Preferences/pympress on macOS,

       • in the top-level of the pympress install directory for portable installations.

       The path to the currently used configuration file can be  checked  in  the  Help  >  About
       information window.

   Shortcuts
       The shortcuts are parsed using Gtk.accelerator_parse():
          The format looks like “<Control>a” or “<Shift><Alt>F1” or “<Release>z” (the last one is
          for key release).

          The parser is fairly liberal and allows lower or upper  case,  and  also  abbreviations
          such  as  “<Ctl>”  and “<Ctrl>”. Key names are parsed using Gdk.keyval_from_name(). For
          character keys the name is not the symbol, but the lowercase name, e.g. one  would  use
          “<Ctrl>minus” instead of “<Ctrl>-”.

       This  means  that  any  value in this list of key constants is valid (removing the initial
       Gdk.KEY_ part). You can verify that this  value  is  parsed  correctly  from  the  Help  >
       Shortcuts information window.

   Layouts
       The  panes  (current  slide,  next  slide,  notes,  annotations,  etc.)  can be rearranged
       arbitrarily by setting the entries of the layout section in the configuration file.   Here
       are  a  couple  examples  of  layouts, with Cu the current slide, No the notes half of the
       slide, Nx the next slide:

       • All-horizontal layout:

            +----+----+----+
            | Cu | No | Nx |
            +----+----+----+

         Setting:

            notes = {"children": ["current", "notes", "next"], "proportions": [0.33, 0.33, 0.33], "orientation": "horizontal", "resizeable": true}

       • All-vertical layout:

            +----+
            | Cu |
            +----+
            | No |
            +----+
            | Nx |
            +----+

         Setting:

            notes = {"children": ["current", "notes", "next"], "proportions": [0.33, 0.33, 0.33], "orientation": "vertical", "resizeable": true}

       • Vertical layout with horizontally divided top pane:

            +----+----+
            | Cu | No |
            +----+----+
            |    Nx   |
            +---------+

         Setting:

            notes = {"children": [
                           {"children": ["current", "notes"], "proportions": [0.5, 0.5], "orientation": "horizontal", "resizeable": true},
                           "next"
                      ], "proportions": [0.5, 0.5], "orientation": "vertical", "resizeable": true}

       • Horizontal layout with horizontally divided right pane:

            +----+----+
            |    | Nx |
            + Cu +----+
            |    | No |
            +---------+

         Setting:

            notes = {"children": [
                           "current",
                           {"children": ["next", "notes"], "proportions": [0.5, 0.5], "orientation": "vertical", "resizeable": true}
                      ], "proportions": [0.5, 0.5], "orientation": "horizontal", "resizeable": true}

       And so on. You can play with the items, their nesting, their order, and the orientation in
       which a set of widgets appears.

       For  each  entry  the  widgets  (strings  that  are  leaves  of  "children"  nodes in this
       representation) must be:

       • for notes: "current", "notes", "next"

       • for plain: "current", "next" and "annotations" (the annotations widget is  toggled  with
         the A key by default)

       • for highlight: same as plain with "highlight" instead of "current"

       A few further remarks:

       • If  you  set  "resizeable"  to  false,  the panes won’t be resizeable dynamically with a
         handle in the middle

       • "proportions" are normalized,  and  saved  on  exit  if  you  resize  panes  during  the
         execution.  If you set them to 4 and 1, the panes will be 4 / (4 + 1) = 20% and 1 / (4 +
         1) = 100%, so the ini will contain something like 0.2 and 0.8 after executing pympress.

   Themes on Windows
       Pympress uses the default Gtk theme of your system, which makes it easy to change on  many
       OSs  either globally via your Gtk preferences or per application.  Here’s the way to do it
       on windows:

       1. Install a theme

          There are 2 locations, either install  the  theme  for  all  your  gtk  apps,  e.g.  in
          C:\Users\%USERNAME%\AppData\Local\themes,    or    just    for    pympress,    so    in
          %INSTALLDIR%\share\themes                (for                 me                 that’s
          C:\Users\%USERNAME%\AppData\Local\Programs\pympress\share\themes)

          Basically pick a theme e.g. from this list of dark themes and make sure to unpack it in
          the  selected  directory,   it   needs   at   least   %THEMENAME%\gtk-3.0\gtk.css   and
          %THEMENAME%\index.theme, where THEMENAME is the name of the theme.

          There are 2 pitfalls to be aware of, to properly install a theme:

          • themes that are not self-contained (relying on re-using css from default linux themes
            that you might not have), and

          • linux links (files under gtk-3.0/ that point to a directory above and that need to be
            replaced  by a directory containing the contents of the target directory that has the
            same name as the link file).

       2. Set the theme as default

          Create a  settings.ini  file,  either  under  C:\Users\%USERNAME%\AppData\Local\gtk-3.0
          (global setting) or %INSTALLDIR%\etc\gtk-3.0 (just pympress) and set the contents:

             [Settings]
             gtk-theme-name=THEMENAME

       In testing this  found these 2 stackoverflow questions useful:

       This page contains the inline documentation, generated from the code using sphinx.

       The code is documented in the source using the Google style  for  docstrings.  Sphinx  has
