<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>sane-pnm</B>
|
|
|
|
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.

|
<H2>DEVICE NAMES</H2>
|
|
|
|
This backend provides two devices called
|
|
<B>0</B>
|
|
|
|
and
|
|
<B>1.</B>
|
|
|
|
<A NAME="lbAE"> </A>
|
|
<H2>CONFIGURATION</H2>
|
|
|
|
No configuration required.

The static library implementing this backend.

The shared library implementing this backend (present on systems that

support dynamic loading).

<DD>
|
|
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.

<H2>BUGS</H2>
|
|
|
|
If the pnm backend is installed and saned 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 can access (usually it's running as
|
|
user "sane"). All pnm files can be read if saned runs as root which isn't
|
|
recommended anyway. The pnm backend is disabled 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 pnm backend over saned.
