Quadarto is an Haskell script which performs image tessellation using a QuadTree pattern. The algorithm iterates over the image merging similar square regions of the images on the basis of their level of details.
The algorithm is developed in order as a small toy software for Haskell learning purpose and I'll try to be idiomatic as much as possible.
Quadarto can be installed directly from source:
git clone https://github.com/THeK3nger/quadarto.git
cd quadarto
cabal configure && cabal build
To execute the program, run the following command from the quadarto folder:
cabal run <input_file> <color_threshold> [-o <output_file>]
Where
<input_file>is the input file path.<color_threshold>is a value who indicates how similar two colors have to be in oder to be merged together. Usually values between 50 and 100 are good enough.<output_file>is an optional output file path. If it is not specified the output file will bedefault.png.
There is still a lot of work to do on the algorithm. The software works but it is still heavily non optimized and non idiomatic. I think can be interesting to follow the various commits I'll do to see how the software evolve towards its final idiomatic Haskell version. :)
