NAME
sane-pnm - SANE PNM image reader pseudo-backendDESCRIPTION
The sane-pnm 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 primarily to aid in debugging of SANE frontends. It also serves as an illustrative example of a minimal SANE backend.DEVICE NAMES
This backend provides two devices called 0 and 1.CONFIGURATION
No configuration required.FILES
/usr/lib/x86_64-linux-gnu/sane/libsane-pnm.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-pnm.so
The shared library implementing this backend (present on systems that support dynamic loading).ENVIRONMENT
SANE_DEBUG_PNM
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.BUGS
If the sane-pnm backend is installed and saned(8) is used to allow users on remote computers to scan on the local machine, PNM files can be read by the remote user. This is limited to
the files saned(8) can access (usually it's running as user "sane"). All PNM files can be read if saned(8) runs as root which isn't recommended anyway. The sane-pnm backend is dis‐
abled by default. If you want to use it, enable it with configure (see configure --help for details). Be sure that only trusted users can access the sane-pnm backend over saned(8).AUTHOR
