Migration of hyper-fractal analysis from visual basic 6 to C# .Net

In Grossu et al. (Comput. Phys. Commun. 184 (2013) 1812–1813) we presented Hyper-Fractal Analysis, a visual tool for estimating the fuzzy fractal dimension of images and 4D objects. As Visual Basic 6 could be considered an outdated language, with limited Object-Oriented Programming capabilities, migrating the application to C# .Net was treated in high priority. Following the goal of creating a highly reusable fractal analysis library, the code was also refactored to SOLID. Together with various improvements, the.Net version is also providing new tools for iso-fractal areas identification. The project success was confirmed by a comparative old/new version study. On the other hand, the most relevant functionalities were covered by unit tests.
