       sane-pnm - SANE PNM image reader pseudo-backend

DDEESSCCRRIIPPTTIIOONN
       The ssaannee--ppnnmm library implements a SANE (Scanner Access Now
       Easy) backend that provides access to PNM (Portable aNyMap
       files, which covers PBM bitmap files, PGM grayscale files,
       and PPM pixmap files).  The purpose  of  this  backend  is
       primarly  to aide in debugging of SANE frontends.  It also
       serves as an illustrative example of a minimal SANE  back-
       end.

       This backend provides two devices called 00 and 11..

              If the library  was  compiled  with  debug  support
              enabled,  this  environment  variable  controls the
              debug level for this backend.  E.g., a value of 128
              requests  all  debug output to be printed.  Smaller
              levels reduce verbosity.
