#  What is
Pympress?
Pympress is a little PDF reader written in Python using Poppler for PDF rendering and GTK+ for the GUI.
It is designed to be a dual-screen reader used for presentations and public talks, with two displays: the
Content window for a projector, and the Presenter window for your laptop. It is portable and has been
tested on various Mac, Windows and Linux systems.
It comes with many great features ([more below](#functionalities)): - supports embedded gifs and videos -
text annotations displayed in the presenter window - natively supports beamer's notes on second screen!
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](https://github.com/Schnouki), on [his
repo](https://github.com/Schnouki/pympress).
Here is what the 2 screen setup looks like, with a big notes slide next to 2 small slides (current and
next) on the presenter side: 
# Installing
• Linux, macOS: pip install pympress − requires [python, gtk+3, poppler, and their python
bindings](#dependencies).
• Windows: choco install pympress with [Chocolatey](https://chocolatey.org/) or download the installer
from the [latest Github release](https://github.com/Cimbali/pympress/releases/latest).
### 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](https://www.videolan.org/vlc/). - On Linux and macOS,
make sure you have all [the dependencies](#dependencies), as they do not come via pip. (On Windows, they
are included in the binary package.) - Using pip, you may want to use python3 -m pip as the command if
pip points to the python 2.x pip. You may also want to install with the --user option, or install from
github or downloaded sources. See [the python documentation on installing](‐
https://docs.python.org/3.7/installing/index.html) for more details.
### Troubleshooting - If your python environment lacks the Gobject Introspections module, try
1. checking you have all [the dependencies](#dependencies),
2. using --system-site-packages for [virtual environments](‐
https://docs.python.org/3.7/library/venv.html),
3. installing pygobject from pip (pip install pygobject, which requires the correct development/header
packages. See [the PyPI installation instructions of PyGObject for your system](‐
https://pygobject.readthedocs.io/en/latest/getting_started.html)).
• For manually downloaded installers, 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)](‐
https://www.microsoft.com/en-in/download/details.aspx?id=5555) or [x64 (64 bits)](‐
https://www.microsoft.com/en-us/download/details.aspx?id=14632)). Those libraries really should already
be installed on your system.
# 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, or beamer notes on second slide). The position of the beamer 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 S
• Estimated 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, in ~/.config/pympress or
~/.pympress on linux, and in %APPDATA%/pympress.ini on windows.
• 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.
## 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).
# Dependencies
Pympress relies on: * Python (version 3.x strongly recommended though 2.7 should still work fine). *
[Poppler](http://poppler.freedesktop.org/), the PDF rendering library. * [Gtk+ 3](http://www.gtk.org/),
a toolkit for creating graphical user interfaces, and [its dependencies](‐
https://www.gtk.org/overview.php), specifically:
• [Cairo](https://www.cairographics.org/) (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](https://wiki.gnome.org/Projects/PyGObject). 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](https://www.videolan.org/vlc/), to play videos (with the same bitness as Python)
### 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 in 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 macOS
Dependencies can be installed using [Homebrew](https://brew.sh/):
brew install gtk+3 poppler gobject-introspection pygobject3
### On windows The [binary installer for windows](#installing) 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](‐
https://github.com/Cimbali/pympress/tree/master/scripts/build_msi_mingw.sh).
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](https://www.python.org/downloads/windows/)
• Get GTK+3, Poppler and their python bindings by executing [the PyGi installer](‐
https://sourceforge.net/projects/pygobjectwin32/). 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](‐
https://wiki.gnome.org/Projects/GTK+/Win32/MSVCCompilationOfGTKStack) and [this python script that
compiles the whole Gtk+3 stack](https://github.com/wingtk/gvsbuild/). This strategy has not been used
successfully yet, due to problems building Poppler with its introspection bidings (i.e. typelib) − see
[#109](https://github.com/Cimbali/pympress/issues/109).
# Contributing
Feel free to clone this repo and use it, modify it, redistribute it, etc, under the GPLv2+. Pympress has
inline sphinx documentation ([Google style](http://www.sphinx-doc.org/en/latest/ext/example_google.html),
contains rst syntax), and the [docs folder](https://github.com/Cimbali/pympress/tree/master/docs/)
contains the documentation generated from it, hosted on [the github pages of this repo](‐
https://cimbali.github.io/pympress/pympress.html).
## Translations
If you want to add a translation, check if pympress/share/locale/<language>/pympress.po already exists.
If not, take [the template file](‐
https://github.com/Cimbali/pympress/tree/master/pympress/share/locale/pympress.pot) as input and
translate all the strings, then add it to the repo in pympress/share/locale/<language>/pympress.po.
Finally pass this .po file to msgfmt and add the output to the repo at
pympress/share/locale/<language>/LC_MESSAGES/pympress.mo.
## Packages
Official releases are made to [PyPI](https://pypi.org/) and with [github releases](‐
https://github.com/Cimbali/pympress/releases). The community maintains a number of other packages or
recipes to install pympress (and more can be added to this list): - [@Jose1711](‐
https://github.com/jose1711) made the [AUR pympress package](‐
https://aur.archlinux.org/packages/python-pympress/) - [@ComFreek](https://github.com/ComFreek) maintains
the [Chocolatey pympress package](https://chocolatey.org/packages/pympress) # Pympress package
This page contains the inline documentation, generated from the code using sphinx.
The code is documented in the source using the [Google style](‐
https://google.github.io/styleguide/pyguide.html) for docstrings. Sphinx has gathered a [set of
examples](http://www.sphinx-doc.org/en/latest/ext/example_google.html) which serves as a better crash
course than the full style reference.
Retructured text (rst) can be used inside the comments and docstrings.
