I recently came across ImagePlay on HackerNews.
ImagePlay is a rapid prototyping tool for building and testing image processing algorithms. It comes with a variety of over 70 individual image processors which can be combined into complex process chains. ImagePlay is completely open source and can be built for Windows, Mac and Linux.
It’s GPLv3, so I thought people might like to have a play with it.
Who doesn’t love graphs and nodes? 
Actually I’m wondering if there’s a user-friendly implementation of jonnors work on imgflo and flowhub? He had built out some infrastructure for the grid.io site using GEGL nodes on the server side, and an HTTP API…
I’ve read the news on HackerNews too and I actually wonder why this made a piece of news 
There have been so many similar “visual programming” tools for image processing for years now (and free to use), for instance:
It’s cool to have an other visual programming tool for image processing anyway. I still wonder how they can stand out from the existing. Just curious.
Good luck to them by the way!
What we need is a better front-end to connect to G’MIC on the server side… 
There I might have some ideas… I’ve a working interface between G’MIC and VIPS, and VIPS has complete and well established python bindings. This might already allow to make use of G’MIC filters on the server side? I’m not an expert on that, but to me it sounds possible.
Well, you can already call G’MIC from a server, with the G’MICol service : https://gmicol.greyc.fr/
I’m not the one who did this service, so I’m not sure how easy it could be to call this service from another web interface, but I can ask
It looks nice on the screenshots, but at least when I tried it on a mac it was completely b0rked. Hard to use and ended up freezing all the time. 
For Ubuntu 14.04/15.04 and Mint 17.x you can find imageplay package in my PPA ppa:dhor/myway. To activate it in system:
sudo add-apt-repository ppa:dhor/myway
sudo apt-get update
sudo apt-get install imageplay
… or use GUI Software Sources in System Settings.
We are thankful for bug reports and any help: Issues · cpvrlab/ImagePlay · GitHub
We have released beta.5 last Friday, stability on Mac has been much improved.
Cool, I only have a (up to date) mac in the office. I’ll check it out on Monday.
