## Installation
A brief description on how to set-up a Raspberry Pi to use this photobooth software.
1. Download latest Raspbian image and set-up an SD-card. You can follow [these instruction](https://www.raspberrypi.org/documentation/installation/installing-images/README.md).
If your display needs some additional configuration, change the file `config.txt` in the `boot`-partition to your needs. For example, I'm using a [Pollin LS-7T touchscreen](http://www.pollin.de/shop/dt/NTMwOTc4OTk-), for which I need to enter the following to avoid overscan:
```
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 6 0 0 0
```
2. Insert the SD-card into your Raspberry Pi and fire it up. Use the `rpi-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.).
3. Reboot and open a terminal. Type `sudo rpi-update` to install the latest software versions. Reboot.
4. Run `sudo apt-get update` and `sudo apt-get upgrade` to upgrade all installed software.
5. Install any additionally required software:
* Pillow:
```
sudo apt-get install python-dev python-pip
sudo pip install Pillow
```
* xinput_calibrator to calibrate touchscreens:
```
wget http://adafruit-download.s3.amazonaws.com/xinput-calibrator_0.7.5-1_armhf.deb
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
```
Calibrate by calling `xinput_calibrator` and pasting the showed snippet to a new file `/etc/X11/xorg.conf.d/99-calibration.conf` (Create the directory if necessary).
6. Checkout the Photobooth repository
```
git clone https://github.com/reuterbal/photobooth
```
## Modifications
In the beginning of the file a number of config options are available. Change them to your liking.
In the beginning of `photobooth.py` a number of config options are available. Change them to your liking.
The GUI-class is separated from the entire functionality. I'm using Pygame because it's so simple to use. Feel free to replace it by your favorite library.
