Would the next step be for me to prepare a PR based on this? yes I think so. Perhaps start small with just one distribution function, and once this initial PR is merged you can follow up with other ones -- http://www.spatialys.com My software is free, but my time generally not. __

Hi all, I implemented a plugin raster format that produces raster of random values using the all the distributions that are offered by the standard library's random header. It is different from other random raster functionality in e.g. ArcGIS or QGIS because it does not store the data on file b
