gwyddion src 76f3fe25d92f2690b435692c9826712316ce8646f2e2fa00a6a42bb25ce8d059 A SPM (scanning probe microscopy) data visualization and analysis tool Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM) and it supports many SPM data formats. However, it can also be used for general height field and image processing, for instance for analysis of profilometry data. Gwyddion aims to provide a modular program for 2D data processing and analysis that can be easily extended by third-party modules and scripts. Moreover, the status of free software enables to provide the source code to developers and users, which makes the further program improvement easier. Its graphical user interface is based on Gtk+. bero <bero@lindev.ch> https://gwyddion.net/
