pibooth 0.0.6

A Photo Booth application in pure Python for the Raspberry Pi.

The pibooth project attempts to provide a Photo Booth application out-of-the-box for Raspberry Pi.

Requirements

The requirements listed below are the one used for the development of pibooth, but other configuration may work fine. All hardware buttons and lights are optional.

Hardware:

• 1 Raspberry Pi 2 Model B (or higher)

• 1 Camera (Pi Camera v2.1 8 MP 1080p or any camera compatible with gphoto2)

• 2 push buttons

• 2 LEDs

• 2 resistors of 100 Ohm

• 1 printer (optional)

Software:

• Python 3.5.3

• RPi.GPIO 0.6.3

• picamera 1.13

• Pillow 4.0.0

• pygame 1.9.3

• gphoto2 1.8.0 ( libgphoto2 2.5.15 )

• pycups 1.9.73 ( CUPS 2.2.1 )

Install

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

1. Download latest Raspbian image and set-up an SD-card. You can follow these instructions .

2. Insert the SD-card into the Raspberry Pi and fire it up. Use the raspi-config tool that is shown automatically on the first boot 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. Reboot and open a terminal. Install the latest firmware version:

   $ sudo rpi-update

4. Upgrade all installed software:

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

5. Optionally install gphoto2 (required only for external camera):

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

6. Optionally install CUPS to handle printers (more instruction to add a new printer can be found here):

   $ sudo apt-get install cups libcups2-dev

7. Install pibooth from the pypi repository:

   $ sudo pip install pibooth

   Hint

   If you don’t have gphoto2 and/or CUPS installed (steps 5. and/or 6. skipped), use the --no-deps option to avoid installation failures (you may need to install Python dependencies yourself)

Run

Start the Photo Booth application using the command:

$ pibooth

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

Action	Keyboard key	Physical button
Toggle Full screen	Ctrl + F	-
Choose pictures	LEFT or RIGHT	Button 1
Take pictures	P	Button 1
Export Printer/Cloud	Ctrl + E	Button 2
Quit	ESC	-

All pictures taken are stored in a subfolder of the one defined in the configuration, named YYYY-mm-dd hh-mm-ss which the time when first photo of the sequence was taken.

Configuration

At the first run, a configuration file is generated in ~/.config/pibooth/pibooth.cfg which permits to configure the behavior of the application. The configuration can be easily edited using the command:

$ pibooth --config

The default configuration can be restored with the command:

$ pibooth --reset

Below is the default configuration file:

[GENERAL]
# User interface language (fallback to English if not found)
language = en

# Path to save pictures
directory = ~/Pictures/pibooth

# Cleanup the 'directory' before start
clear_on_startup = True

# How long to debounce the button in seconds
debounce_delay = 0.3

[WINDOW]
# (width, height) of the display monitor or 'fullscreen'
size = (800, 480)

# Blinking background when picture is taken
flash = True

# How long is the preview in seconds
preview_delay = 3

# Show a countdown timer during the preview
preview_countdown = True

# Keep background images in a buffer (best performances but more memory used)
buffer = True

[PICTURE]
# How many pictures to take by default (4 max)
captures = 4

# First text displayed
footer_text1 = Footer 1

# Second text displayed
footer_text2 = Footer 2

# Footer text RGB color
text_color = (0, 0, 0)

# Background RGB color
bg_color = (255, 255, 255)

[CAMERA]
# Resolution for camera captures (see picamera modes)
resolution = (1920, 1080)

# Adjust for lighting issues (normal is 100 or 200. Dark is 800 max)
iso = 100

# Rotation of the camera (valid values are 0, 90, 180, and 270)
rotation = 0

[PRINTER]

# Name of the printer to send the pictures
printer_name = default

# How long is the print view in seconds (0 to skip it)
printer_delay = 10

Run pibooth at startup

To run pibooth in fullscreen at the boot of the raspberry pi follow these instructions:

1. Create a pibooth.desktop file in the ~/.config/autostart/ folder

2. Fill the following info in the file:

[Desktop Entry]
Name=pibooth
Exec=pibooth
Type=application

Printer configuration

Here is the default configuration used in CUPS, this 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)
