PiCameraApp: A graphical user interface (GUI) for the Picamera library written in Python using Tkinter / ttk.
While developing a camera interface to a 32x32 RGB matrix, I was constantly programming the Picamera in code to test options. I decided to develop a GUI that provides an interface to all of the Picamera's API. Since I haven't done much GUI programming in Linux, I used the Tkinter API.
Note: I am an old (old, old, old, ..., so very old) Windows programmer going back to the days of Windows 2.1 (Petzold). Both the Python language as well as Linux on the Raspberry Pi are new to me, so please forgive unintentional (or blatant) misuses of the API or Python coding 'standards'.
Download the Source directory and execute PiCameraApp.py. Under Wheezy, you must run as root in order to access the GPIO on the PiCamera. If you are not running as root, then the LED interface is disabled.
To run, open a terminal, change to the directory containing the source files, and enter sudo python PiCameraApp.py.
PiCameraApp has been developed using Python ver 2.7. In addition, it uses the following additonal Python libraries:
| Library | Usage |
|---|---|
| picamera | The python interface to the PiCamera hardware. See https://picamera.readthedocs.io/en/release-1.13/install.html |
| RPi.GPIO | Required to toggle the LED on the camera. Can get it at http://www.raspberrypi-spy.co.uk/2012/05/install-rpi-gpio-python-library/ |
| PIL | The Python Image Library. |
