sane-qcam(5)		 SANE Scanner Access Now Easy		  sane-qcam(5)

NAME
       sane-qcam - SANE backend for Connectix QuickCam cameras

DESCRIPTION
       The sane-qcam library implements a SANE (Scanner Access Now Easy) back‐
       end that provides access Connectix QuickCam cameras.

DEVICE NAMES
       This backend expects device names of the form:

	      port

       Where port 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.

CONFIGURATION
       The contents of the qcam.conf 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).

FILES
       /etc/sane.d/qcam.conf
	      The   backend   configuration  file  (see	 also  description  of
	      SANE_CONFIG_DIR below).

       /usr/lib/arch_triplet/sane/libsane-qcam.a
	      The static library implementing this backend.

       /usr/lib/arch_triplet/sane/libsane-qcam.so
	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

ENVIRONMENT
       SANE_CONFIG_DIR
	      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 /etc/sane.d.	If the
	      value  of the environment variable ends with the directory sepa‐
	      rator character, then the default directories are searched after
	      the  explicitly  specified  directories.	 For  example, setting
	      SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
	      "tmp/config",  ".",  and	"/etc/sane.d"  being searched (in this
	      order).

       SANE_DEBUG_QCAM
	      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.

BUGS
       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-privileges since it needs to be able to access
       the camera's I/O ports.
