) and extended to handle scanning microscope images, especially of the SxM formats (SAM, SCM, SEM, SFM, SLM, SNOM, SPM, STM), hence its name.
Features
Image SXM supports image ''stacks'', a series of images that share a single window. It can calculate area and pixel value statistics of user-defined selections and intensity thresholded objects. It can measure distances and angles. It can create density
