sane-qcam - SANE backend for Connectix QuickCam cameras

<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
The <B>sane-qcam</B> library implements a SANE (Scanner Access Now Easy) back-
|
|
|
|
|
end that provides access Connectix QuickCam cameras.
|
|
|
|
|
|
|
|

|
<H2>DEVICE NAMES</H2><PRE>
|
|
|
|
|
This backend expects device names of the form:
|
|
|
|
|
|
|
|
|
|
<I>port</I>
|
|
|
|
|
|
|
|
|
|
Where <I>port</I> is the I/O port address at which the device resides. This
|
|
|
|
|
address is normally specified in hexadecimal using C syntax (e.g.,
|
|
|
|
|
0x37b) and may be prefixed with the letter "u" (e.g., u0x37b) to force
|
|
|
|
|
the backend to access the camera in uni-directional mode.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
</PRE>
|
|
|
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
|
|
|
The contents of the <I>qcam.conf</I> file is a list port addresses that may be
|
|
|
|
|
connected to a Connectix QuickCam. Empty lines and everything starting
|
|
|
|
|
from a hash mark (#) up to the end of a line are ignored. A sample
|
|
|
|
|
configuration file is shown below:
|
|
|
|
|
|
|
|
|
|
0x37b # /dev/lp0
|
|
|
|
|
0x378 # /dev/lp1
|
|
|
|
|
u0x278 # /dev/lp2 forced in uni-directional mode
|
|
|
|
|
0x3bc # /dev/lp0 (alternate address)
|
|
|
|
|
|
|
|
|
|
In general, it is safest to list only the port addresses that really
|
|
|
|
|
correspond to a QuickCam. For example, if one of the listed addresses
|
|
|
|
|
actually connect to a printer, then starting up this backend will cause
|
|
|
|
|
the printer to perform a device reset (which is generally undesirable).

<H2>FILES</H2><PRE>
|
|
|
|
|
<I>/usr/local/etc/sane.d/qcam.conf</I>
|
|
|
|
|
The backend configuration file (see also description of
|
|
|
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
|
|
|
|
|
|
<I>/usr/local/lib/sane/libsane-qcam.a</I>
|
|
|
|
|
The static library implementing this backend.
|
|
|
|
|
|
|
|
|
|
<I>/usr/local/lib/sane/libsane-qcam.so</I>
|
|
|
|
|
The shared library implementing this backend (present on systems
|
|
|
|
|
that support dynamic loading).

<H2>ENVIRONMENT</H2><PRE>
|
|
|
|
|
<B>SANE_CONFIG_DIR</B>
|
|
|
|
|
This environment variable specifies the list of directories that
|
|
|
|
|
may contain the configuration file. Under UNIX, the directories
|
|
|
|
|
are separated by a colon (`:'), under OS/2, they are separated
|
|
|
|
|
by a semi-colon (`;'). If this variable is not set, the config-
|
|
|
|
|
uration file is searched in two default directories: first, the
|
|
|
|
|
current working directory (".") and then in
|
|
|
|
|
/usr/local/etc/sane.d. If the value of the environment variable
|
|
|
|
|
ends with the directory separator character, then the default
|
|
|
|
|
directories are searched after the explicitly specified directo-
|
|
|
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
|
|
|
would result in directories "tmp/config", ".", and
|
|
|
|
|
"/usr/local/etc/sane.d" being searched (in this order).
|
|
|
|
|
|
|
|
|
|
<B>SANE_DEBUG_QCAM</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>
|
|
|
|
|
Support is currently limited to the color version of the QuickCam. The
|
|
|
|
|
black-and-white camera is starting to work too, but I don't believe it
|
|
|
|
|
works in all cases yet. Reportedly, acquiring images of certain sizes
|
|
|
|
|
work fine, but others result in shifted images (sounds like a problem
|
|
|
|
|
due to byte-padding).
|
|
|
|
|
|
|
|
|
|
The program needs root-priviledges since it needs to be able to access
|
|
|
|
|
the camera's I/O ports.
