sane-pnm - SANE PNM image reader pseudo-backend

|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-pnm</B> library implements a SANE (Scanner Access Now Easy) back-
|
|
end that provides access to PNM (Portable aNyMap files, which covers
|
|
PBM bitmap files, PGM grayscale files, and PPM pixmap files). The pur-
|
|
pose of this backend is primarily to aid in debugging of SANE fron-
|
|
tends. It also serves as an illustrative example of a minimal SANE
|
|
backend.

|
<H2>DEVICE NAMES</H2><PRE>
|
|
This backend provides two devices called <B>0</B> and <B>1.</B>
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
No configuration required.
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/lib/sane/libsane-pnm.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-pnm.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_DEBUG_PNM</B>
|
|
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><PRE>
|
|
If the <B>sane-pnm</B> backend is installed and <B><A HREF="saned.8.html">saned(8)</A></B> 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 <B><A HREF="saned.8.html">saned(8)</A></B> can
|
|
access (usually it's running as user "sane"). All PNM files can be read
|
|
if <B><A HREF="saned.8.html">saned(8)</A></B> runs as root which isn't recommended anyway. The <B>sane-pnm</B>
|
|
backend is disabled by default. If you want to use it, enable it with
|
|
configure (see <I>configure</I> <I>--help</I> for details). Be sure that only trusted
|
|
users can access the <B>sane-pnm</B> backend over <B><A HREF="saned.8.html">saned(8)</A></B>.
