sane-pnm(5)

NAME
sane-pnm - SANE PNM image reader pseudo-backend

DESCRIPTION
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 primarly to aide 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

@LIBDIR@/libsane-pnm.a
    The static library implementing this backend.

@LIBDIR@/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.
