The Scalable Function Graphic Converter
PhotoFunction is a free, prototype piece of software that uses a machine learning algorithm to develop complex mathematical functions that define given images. These mathematical functions can then be used to scale the corresponding images up dramatically, without blurring or loss of quality.
To use this software first download the '.zip' file to the right.
Once it has downloaded, right click on the file and select 'Extract'. This will unpack the zip file into a folder called 'PhotoFunction'.
Double clicking on the 'PhotoFunction.jar' file inside this folder will launch the PhotoFunction program (you may need to assign executable priviledges in Ubuntu). Full instructions for use are contained, along with active prompts to make things easier.
Bear in mind that PhotoFunction is a minimalist prototype, intended to demo an image conversion and rendering technology. As such the program has a minimal user interface, with the vast majority of time having gone into the development of Scalable Function Graphics along with the PhotoFunction learning algorithm.
Do not store the the 'PhotoFunction' folder in a UAC protected directory, such as 'C:\Program Files\...'. Typical security settings will prevent PhotoFunction from being able to save and render SFG files within this directory.
Additionally do not move or rename any of the folders contained within the 'PhotoFunction' folder.

The wiki commons photograph 'Sunset from Battery Park, New York City' by Alex Proimos has been cropped and scaled down to a 40 by 40 thumbnail. It has then been scaled back up 1000% in order to compare different scaling algorithms and demonstrate the quality of scalable function graphics.
Note: PhotoFunction requires Java. The '.jar' file will launch in an operating system with an installed JRE.
