NAME

       imview - displays and interactively analyses images

SYNOPSIS

       imview [ options ] [ image ... ]

       Where  image  is an image file in one of the supported formats, e.g: TIFF, JPEG, GIF, PNG,
       BMP, XPM, PNM, etc...

DESCRIPTION

       Imview is an X11 and Windows GDI GUI application for displaying images on screen.  It  has
       advanced  capabilities  for interactive image analysis (getting information out of images)
       and can be easily controlled through a socket connection for embedding in  image  analysis
       systems.

       Imview  supports  a  large  number  of  popular and scientific image file formats, in part
       through the use of the ImageMagick library.

OPTIONS

       Here is the complete list of optional arguments for imview.

       -      Reads an image from the standard input stream. Example:

       -a     Reads and appends to an existing pointfile (see option -p).

       -C <lutname>
              Specifies <lutname> as the default look-up tables for all the images on the command
              line.

       -c <lutname>
              Applies the look-up table <lutname> to the preceding image on the command line (see
              example section).

       -debug Starts a debugging GUI console where debugging messages can be seen (there are lots
              of them!). Under Unix messages are also appended to the file /tmp/imbugs.txt.

       -delete
              Any  image  given to imview on the command line will be deleted after imview exits.
              This is useful when imview is started from an interpreter with a temporary image as
              argument.  For safety only images with paths beginning with /tmp, /usr/tmp or under
              the standard  environment  variable-controlled  TMPDIR  directory  are  effectively
              deleted.

       -disable_io_keys
              This  option disables some I/O shortcut that are not menu-dependent, such as c that
              closes an image. This is useful  in  conjunction  with  options  -hide_menubar  and
              -disable_menubar for limiting the user's interaction with the application.

       -disable_menubar
              This  option  completely  disables  the  menu  bar  (but  does  not  hide  it,  see
              -hide_menubar for that). Both hiding and disabling the menubar at the same time can
              be  useful for producing a viewer that users cannot control other than through some
              other means than the menu  (if  imview  is  embedded  in  another  application  for
              example).

       -disable_quit
              This  option disables the shortcut ways of quitting the imview application, such as
              the Escape key, clicking the windows manager `close window' button,  etc.  This  is
              useful to restrict the user's control over imview.

       -fork  Sends  imview  to  the background (works on all platforms including windows). It is
              better to use this option rather than the shell semantics (adding & at the  end  of
              the command under Unix) when the server is ran in conjunction with -server, because
              imview will synchronize  the  foreground  and  background  processes  so  that  the
              foreground process can know the server port number.

       -gamma <value>
              Sets  the  default  gamma for all the images. A gamma between 0 and 1.0 will darken
              the displayed image while a gamma greater than 1.0 will brighten them.

       -h     Prints an abbreviated list of options and exits.

       -hide_menubar
              Hides the main menubar. The menu items are  still  accessible  via  shortcuts.  For
              example  try  Alt+f to get the file->open menu. From there you can use the keyboard
              arrow keys to select a menu item for example. This is useful  if  you  have  little
              screen real estate, but confusing for the beginner!

       -no_dblbuf
              Do  not use double buffering at certain zoom factors. This is a hack you might want
              to experiment with if you find that imview does not redraw  some  parts  of  images
              after closing and re-opening images.

       -locked
              Equivalent   to   all   the   following   options   used  together:  -hide_menubar,
              -disable_menubar, -disable_iokeys and  -disable_quit.  If  run  with  this  option,
              imview  can  only  be  controlled  via  a socket in server mode. This is useful for
              embedding imview in another application.

       -mag <zoom facto>
              Magnifies all images by  <zoom  factors>.  Any  positive  value  is  legal.  Values
              between  0 and 1.0 will reduce the size of the images while values greater than 1.0
              will expand them.

       -no_magick
              Disables the use of the ImageMagick  library.  This  library  is  very  useful  for
              reading  and  writing  a  large  number  of  file  formats but tries to do too much
              sometimes, such as converting text files to images.

       -p <pointfile>
              Specifies the point file name. A pointfile is a regular text file  in  which  point
              (pixel) information can be recorded. The default point file name is pointfile. This
              option simply changes that default, no other action is taken.

       -portfile <file>
              This option is only useful in combination with -server. Imview's server binds to  a
              port in the range 7600-7700. Because it is often useful to have more than one image
              server at the same time and because  of  the  interactive  nature  of  imview,  the
              precise  port  number  is  impossible  to predict, so when the server is started it
              prints the port it decided to bind against on the command line, or alternatively in
              a file, specified by this option.

              NOTE:  If  you  are  planning to send imview to the background, for this command to
              work as expected, you must also use the -fork  option,  otherwise  the  file  might
              still be empty when the command returns.

       -server
              Starts  the  imview  server.  In  server mode imview performs as a TCP/IP server on
              which images can be uploaded and commands can be run. The aim  is  to  make  imview
              completely  remote-controllable:  every command accessible via the menu can also be
              made available through the server.

              Imview uses its own text-based protocol. For  simple  commands  a  standard  telnet
              session  is  enough  to  communicate with imview. However for uploading images into
              imview a protocol similar to FTP has been implemented. A simple  imview  client  is
              shipped  in  source  form  with the imview distribution. For a specification of the
              imview protocol see the full documentation.

              Imview's server port number is in  the  range  7600-7700  which  allows  up  to  50
              different  imview  server  to  be  run on the same machine (each server uses up two
              ports: one for commands and the other for binary data exchange, such  as  uploading
              images).

       -stopdebug
              Used  in  conjunction  with  -debug,  will  stop  the  program after each debugging
              message. To continue the user must type <Enter>.

       -v     Prints the version and build numbers, the date of build, the configuration  options
              and exits.

       -wt <title>
              Changes the title of the main window. The default is Imview.

EXAMPLES

       In the following examples `%' indicate the shell prompt.

   SIMPLE USAGE
        % imview

       Simply  starts  imview displaying the splash screen. An image can then be loaded using the
       menus.

        % imview myimage.tiff

       Will display image myimage.tiff.

        % imview /home/talbot/images/astro/*

       Will display all images in the directory  /home/talbot/images/astro/.  Use  <spacebar>  to
       switch from one image to the next.

   ADVANCED USAGE
        % imview aGreyLevelImage.tif -c heat.lut

       Will  display  image  aGreyLevelImage.tif.  Assuming  this  image only contains grey-level
       information (a black and white photograph for  example),  the  false  colours  defined  in
       heat.lut will be applied to it.

   SERVER USAGE
        % imview -server -fork
       Port: 7600

       This  will  start  imview in server mode. The only difference with the normal mode is that
       imview can now be "remote-controlled" via a TCP/IP connection. The port imview is bound to
       is  printed  on  the  command  line  when  the server starts. To save it to a file use the
       -portfile option.

       A simple telnet session can be used to remote-control imview, as  follows.  See  the  full
       documentation for more details:

        % telnet localhost 7600
       user talbot
       Welcome, talbot /tmp/fileBlabla 000 OK
       load "/home/talbot/images/astro/neptune.tiff"
       000 OK
       zoom factor 2
       000 OK
       end
       Connection closed by foreign host.

       imclient  is  shipped with the source distribution as an implementation of a sample client
       that can upload images into imview, as follows:

        % imclient -p 7600 /home/talbot/images/astro/jupiter.tiff

BUGS

       See the TODO file in the source distribution or the web site for an updated list of  known
       bugs. Here is a list of the most significant ones:

       · resize  still  a problem sometimes. Imview gets itself into a weird state with incorrect
         limits and partial redraws. Specifying a complete redraw  should  clear  everything  but
         doesn't.

       · Move  to  the middle of the screen. Sometimes for no apparent reason Imview moves to the
         middle of the screen. This seems to be happening if the main window resises.

       · last line and last column of image often missing when scrollbar are present.
