       IIPSRV - IIPImage Internet Imaging Server


       IIPImage  is an advanced high-performance feature-rich imaging server system for web-based
       streamed viewing and zooming of ultra high-resolution images. It is designed  to  be  fast
       and  bandwidth-efficient  with  low  processor  and  memory  requirements.  The system can
       comfortably handle gigapixel size images as well as advanced image features such as both 8
       and 16 bit depths, CIELAB colorimetric images and scientific imagery such as multispectral


       The iipsrv.fcgi binary can be run as a standalone program or can be automatically  started
       via  a  web server. This package includes configuration files for both Apache and Lighttpd
       that are automatically installed and configured if either of  these  are  installed.   See
       FILES bellow for details.


       The iipsrv.fcgi binary is installed in /usr/lib/cgi-bin/iipsrv.fcgi

       If  you  have  Apache  installed,  make  sure  you  have mod_fastcgi installed. The iipsrv
       configuration file is automatically placed in /etc/apache2/conf.d/iipsrv.conf

       For Lighttpd, the  configuration  file  is  automatically  placed  in  /etc/lighttpd/conf-

       You  can  edit  the  parameters  in these configuration files. See OPTIONS bellow for more
       details. If you modify any parameters, make sure you restart your web server for  them  to
       take effect.


       iipsrv  will be automatically started by both Apache and Lighttpd. If you wish to run as a
       standalone program, use the following syntax to bind to a particular port:

       % /usr/lib/cgi-bin/iipsrv.fcgi --bind localhost:9000

       You will then need to configure your webserver on the same machine or another to point  to
       this  ip address and port.  Use this method for use with Nginx or Java Application Servers
       such as Tomcat, JBoss or Jetty


       There are several parameters that can be supplied to iipsrv.fcgi

              The log file the module will (attempt) to write to. If no value is  given,  no  log
              will  be  written. Make sure the server process has write access to this directory.
              Paths with spaces in them may not work correctly.

              The level of logging. 0 means no logging, 1 is minimal logging, 2 lots of debugging
              stuff  and 3 even more debugging stuff and 4 a very large amount indeed. Logging is
              only enabled if LOGFILE has also been defined.

              The default JPEG quality factor for compression when the client  does  not  specify
              one.  The value should be between 1 (highest level of compression) and 100 (highest
              image quality). The default is 75.

              Max image cache size to be held in RAM in MB. This is a  cache  of  the  compressed
              JPEG image tiles requested by the client. The default is 5MB.

              This  is  a  prefix automatically added by the server to the beginning of each file
              system path. This can be useful for security reasons to  limit  access  to  certain
              sub-directories. For example, with a prefix of "/home/images/" set on the server, a
              request   by   a   client   for   "image.tif"    will    point    to    the    path
              "/home/images/image.tif".  Any reverse directory path component such as ../ is also
              filtered out. No default value.

              The maximum permitted image pixel size returned by the CVT command  in  conjunction
              with  WID  or  HEI  or  RGN.  The default is 5000. This prevents huge requests from
              overloading the server

       LAYERS The number of quality layers to decode for image that support  progressive  quality
              encoding, such as JPEG2000. Ignored for other file formats. The default is 1.

              TIFF  image  to  use as watermark file. This image should be not be bigger the tile
              size used for TIFF tiling. If bigger, it will simply be cropped to the  tile  size.
              If  smaller,  the watermark will be positioned randomly within the available space.
              The image can be either colour or grayscale.

              The probability that a particilar tile will have a watermark applied to it. 0 means
              never, 1 means always.

              The opacity (between 0 and 1) applied to the watermark image.

              A  comma-delimitted  list  of  memcached  servers  with  optional port numbers. For
              example: localhost,,

              Time in seconds that cache remains fresh. Default is 86400 seconds (24 hours).

              Pattern that follows the name stem for a panoramic image sequence.  eg: "_pyr_" for
              FZ1_pyr_000_090.tif.   In  this  example,  just  supply FZ1 to the FIF command. The
              "000" indicates the vertical angle and "090" the horizontal. This is only  relevant
              to 3D image sequences. The default is "_pyr_".


       The  image  paths  given  to the server via the FIF variable must be absolute paths on the
       server machine (eg. FIF=/images/test.tif)  and  not  paths  relative  to  the  web  server
       document  root  location.  Images do not, therefore, need to be directly accessible by the
       client via the web server. Make sure the server process owner is able to access  and  read
       the images!
