DESCRIPTION
       The package img::ppm is a sub-package of Img. It can be loaded as a part of the complete Img support,
       via package require Img, or on its own, via package require img::ppm.

       so that it supports files containing raster images in the Portable Pixmap format (ppm). More specifi-cally specifically

       image create photo ?name? ?options?
