With this, he could control everything remotely and even see the currently displayed image in Home Assistant. In 2021, Helge Erbe, wanting to do something useful during the Corona lock-down, built a PictureFrame integration for Home Assistant, the incredibly versatile home automation system. Over the years, users all over the world discovered the beauty of “PictureFrame powered by Pi3D”. Paddy showed interest in my digital picture frame project and offered to write a Python script that would produce beautiful and customizable image transitions for my exact purpose: PictureFrame.py was born. What that means in layman’s terms is that this software fully exploits the graphical capabilities of the small Raspberry Pi. The software dramatically simplifies writing 3D in Python while giving access to the power of the Raspberry Pi GPU. The “guy” from the forum turned out to be Paddy Gaunt, who, together with Tim Skillman and Tom Ritchford, had written Pi3D, a Python Open GL ES 2.0 library for the Raspberry Pi. It built a slideshow of all files in a directory with four transition options.Īmong them was crossfading. There was one demo that got my attention in particular: SlideTransition. One guy suggested that I take a look at 2D/3D rendering software that came with many demo applications. Taking the Raspberry Pi’s graphical capabilities up a few notchesīack in 2014, I had posted in the English Raspberry Pi forum that I was looking for an image transition software. This is where PictureFrame comes to the rescue. I will explain this in more detail in my article “ 5 essential tips I learned from building digital picture frames“. Here is an example of a 10 seconds crossfade transition effect (comes with soft piano music): A lack of transitions means that there is no emotion, nothing that touches you. But then you would be missing out on something magical. You may say, a standard image hard cut image viewer is good enough. Crossfading transition effects with the right duration are the key to digital picture frame heaven. I have tested many types of transition effects for over 12 years now. There may be a sudden change in brightness, which is uncomfortable, something which distracts and doesn’t feel right. The hard cuts between photos cause quite a disturbance, especially with a larger screen. This may be fine for outdoor advertising, but it is unsuited for any social setting. It can only do a hard cut between images. But the problem with feh is that it offers no transitions between images. When I built my first digital picture frame, I initially used feh for the lack of something better. It is a lightweight image viewer that many tutorials on self-made digital picture frames suggest to use. The standard image viewer on Linux is a package called feh. Use “Buster Desktop” for your picture frame! A world of difference Luckily, the Pi Foundation decided to continue to maintain the previous version “Buster” and will supply regular security patches for it. Important note: The latest Pi OS release “Bullseye” from November 2021 brought a number of changes to the graphics routines which make Pi3D PictureFrame crash (and a number of other graphics programs).
