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 primarly to aid in debugging of SANE frontends.
|
|
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.

<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 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.
