Requirements
------------

The requirements listed below are the ones used for the development of ``pibooth``, but
other configuration may work fine. **All hardware buttons, lights and printer are optional**,
the application can be entirely controlled using a keyboard, a mouse or a touchscreen.

Hardware
^^^^^^^^

* 1 Raspberry Pi 3 Model B (or higher)
* 1 Camera (Raspberry Pi Camera v2.1 8 MP 1080p
  or any DSLR camera `compatible with gPhoto2 <http://www.gphoto.org/proj/libgphoto2/support.php>`_
  or any webcam `compatible with OpenCV <https://opencv.org>`_ )
* 2 push buttons
* 4 LEDs
* 4 resistors of 100 Ohm
* 1 printer

Software
^^^^^^^^

* Raspbian ``Buster with desktop and recommended software``
* Python ``3.5.3``
* libgphoto2 ``2.5.23``
* libcups ``2.2.1``

Install
-------

A brief description on how to set-up a Raspberry Pi to use this software.

1. Download the Raspbian image and set-up an SD-card. You can follow
   `these instructions <https://www.raspberrypi.org/documentation/installation/installing-images/README.md>`_ .

2. Insert the SD-card into the Raspberry Pi and fire it up. Use the ``raspi-config`` tool
   to configure your system (e.g., expand partition, change hostname, password, enable SSH,
   configure to boot into GUI, etc.).

   .. hint:: Don't forget to enable the camera in raspi-config.

3. Upgrade all installed software:

   ::

        $ sudo apt-get update
        $ sudo apt-get upgrade

4. Optionally install the last stable ``gPhoto2`` version (required only for DSLR camera):

   ::

        $ sudo wget raw.github.com/gonzalo/gphoto2-updater/master/gphoto2-updater.sh
        $ sudo chmod 755 gphoto2-updater.sh
        $ sudo ./gphoto2-updater.sh

5. Optionally install ``CUPS`` to handle printers (more instructions to add a new printer can be found
   `here <https://www.howtogeek.com/169679/how-to-add-a-printer-to-your-raspberry-pi-or-other-linux-computer>`_):

   ::

        $ sudo apt-get install cups libcups2-dev

6. Optionally install ``OpenCV`` to improve images generation efficiency or if a Webcam is used:

   ::

        $ sudo apt-get install python3-opencv

7. Install ``pibooth`` from the `pypi repository <https://pypi.org/project/pibooth/>`_:

   ::

        $ sudo pip3 install pibooth[dslr,printer]

   .. hint:: If you don't have ``gPhoto2`` and/or ``CUPS`` installed (steps 5. and/or 6. skipped), remove
             printer or dslr under the []

.. note:: An editable/customizable version of ``pibooth`` can be installed by following
          these `instructions <https://github.com/werdeil/pibooth/blob/master/docs/dev.rst>`_ .
          Be aware that the code on the `master` branch may be unstable.

Run
---

Start the photobooth application using the command::

    $ pibooth

All pictures taken are stored in the folder defined in ``[GENERAL][directory]``. They are named
**YYYY-mm-dd-hh-mm-ss_pibooth.jpg** which is the time when first capture of the sequence was taken.
A subfolder **raw/YYYY-mm-dd-hh-mm-ss** is created to store the single raw captures.

.. note:: if you have both ``Pi`` and ``DSLR`` cameras connected to the Raspberry Pi, **both are used**,
          this is called the **Hybrid** mode. The preview is taken using the ``Pi`` one for a better
          video rendering and the capture is taken using the ``DSLR`` one for better picture rendering.

You can display a basic help on application options by using the command::

    $ pibooth --help

States and lights management
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The application follows the states sequence defined in the diagram below:

.. image:: https://raw.githubusercontent.com/werdeil/pibooth/master/templates/state_sequence.png
   :align: center
   :alt: State sequence

The states of the **LED 1** and **LED 2** are modified depending on the actions available
for the user. The **LED 3** is switched on when the application starts and the **LED 4**
is switched on during the preview and photo capture.

Commands
^^^^^^^^

After the graphical interface is started, the following actions are available:

======================= ================ =====================
Action                  Keyboard key     Physical button
======================= ================ =====================
Toggle Full screen      Ctrl + F         \-
Choose layout           LEFT or RIGHT    Button 1 or Button 2
Take pictures           P                Button 1
Export Printer/Cloud    Ctrl + E         Button 2
Open/close settings     ESC              Button 1 + Button 2
Select option           UP or DOWN       Button 1
Change option value     LEFT or RIGHT    Button 2
======================= ================ =====================

Final picture rendering
^^^^^^^^^^^^^^^^^^^^^^^

The ``pibooth`` application  handle the rendering of the final picture using 2 variables defined in
the configuration (see `Configuration`_ below):

* ``[CAMERA][resolution] = (width, height)`` is the resolution of the captured picture in pixels.
  As explained in the configuration file, the preview size is directly dependent from this parameter.
* ``[PICTURE][orientation] = auto/landscape/portrait`` is the orientation of the final picture
  (after concatenation of all captures). If the value is **auto**, the orientation is automatically
  chosen depending on the resolution.

.. note:: The resolution is an important parameter, it is responsible for the quality of the final
          picture. Have a look to `picamera possible resolutions <http://picamera.readthedocs.io/en/latest/fov.html#sensor-modes>`_ .

Image effects can be applied on the capture using the ``[PICTURE][effect]`` variable defined in the
configuration.

.. code-block:: ini

    [PICTURE]

    # Effect applied on all captures
    captures_effects = film

Instead of one effect name, a list of names can be provided. In this case, the effects are applied
sequentially on the captures sequence.

.. code-block:: ini

    [PICTURE]

    # Define a rolling sequence of effects. For each capture the corresponding effect is applied.
    captures_effects = ('film', 'cartoon', 'washedout', 'film')

Have a look to the predefined effects available depending on the camera used:

* `picamera effects <https://picamera.readthedocs.io/en/latest/api_camera.html#picamera.PiCamera.image_effect>`_
* `gPhoto2 effects (PIL based) <https://pillow.readthedocs.io/en/latest/reference/ImageFilter.html>`_

Texts can be defined by setting the option ``[PICTURE][footer_text1]`` and ``[PICTURE][footer_text2]``
(lets them empty to hide any text). For each one, the font, the color and the alignment can be chosen.
For instance:

.. code-block:: ini

    [PICTURE]

    # Same font applied on footer_text1 and footer_text2
    text_fonts = Amatic-Bold

This key can also take two names or TTF file paths:

.. code-block:: ini

    [PICTURE]

    # 'arial' font applied on footer_text1, 'Roboto-BoldItalic' font on footer_text2
    text_fonts = ('arial', 'Roboto-BoldItalic')

The available fonts can be listed using the following the command::

    $ pibooth --fonts

Configuration
-------------

At the first run, a configuration file is generated in ``~/.config/pibooth/pibooth.cfg``
which permits to configure the behavior of the application.

A quick configuration GUI menu (see `Commands`_ ) gives access to the most common options:

.. image:: https://raw.githubusercontent.com/werdeil/pibooth/master/templates/settings.png
   :align: center
   :alt: Settings

More options are available by editing the configuration file which is easily
done using the command::

    $ pibooth --config

The default configuration can be restored with the command (strongly recommended when
upgrading ``pibooth``)::

    $ pibooth --reset

See the `default configuration file <https://github.com/werdeil/pibooth/blob/master/docs/config.rst>`_
for further details.

GUI translations
----------------

The graphical interface texts are available in 4 languages by default: English, French,
German, Dutch and Spanish. The default translations can be easily edited using the command::

    $ pibooth --translate

A new language can be added by adding a new section (``[alpha-2-code]``).
If you want to have Pibooth in your language feel free to send us the corresponding keywords via a GitHub issue.

Printer
-------

The print button (see `Commands`_) and print states are automatically activated/shown if:

* `pycups <https://pypi.python.org/pypi/pycups>`_ is installed
* at least one printer is configured in ``CUPS``

To avoid paper waste, set the option ``[PRINTER][max_duplicates]`` to the maximum
of identical pictures that can be sent to the printer.

Set the option ``[PRINTER][max_pages]`` to the number of paper sheets available on the
printer. When this number is reached, the print function will be disabled and an icon
indicates the printer failure. To reset the counter, open then close the settings
graphical interface (see `Commands`_).

Here is the default configuration used for this project in CUPS, it may depend on
the printer used:

================ =============================
Options          Value
================ =============================
Media Size       10cm x 15cm
Color Model      CMYK
Media Type       Glossy Photo Paper
Resolution       Automatic
2-Sided Printing Off
Shrink page ...  Shrink (print the whole page)
================ =============================
