       engauge-digitizer  -  interactively  convert a bitmap graph or map into


       engauge [options]


       This manual  page  documents  briefly  the  engauge  command  from  the
       engauge-digitizer package.


       -import FILE
              Automatically  import the specified image file at startup. Image
              files may also be imported manually using the menu

       -open FILE
              Automatically open the specified Engauge Digitizer document file
              at startup. Document files may also be opened manually using the

       -help  Display a list of command line options similar to  this  manpage
              in an X window and exit

       -manual DIRECTORY
              Look  for  the  HTML  user guide in the specified directory. For
              Debian    it    is    installed    in    /usr/share/doc/engauge-
              digitizer/usermanual and should need no configuration.

       -axes XMIN XMAX YMIN YMAX
              Scan  the imported file at startup, and locate the X and Y axes.
              Then digitize axis points assuming the X axis ranges  from  XMIN
              to  XMAX, and the Y axis ranges from YMIN to YMAX. The X axis is
              assumed to be near the bottom of the image, and the  Y  axis  is
              assumed  to  be  on  the  left  side of the image. For speed, no
              attempt to rotate the image if it is sideways, so the  digitized
              points  may  require  adjustment.  This feature should be useful
              when using Perl or other scripts to digitize  many  images  with
              known  axes  ranges.  The  axis  points  may  also  be digitized
              manually using the Digitize Axis Points mode

              Postpone scanning for segments that is normally performed during
              startup,  until  either  the  Segments  dialog  is  used, or the
              Segment Fill button is selected.


       -export FILE
              Automatically export the active document at shutdown.  Documents
              may also be exported manually using the menu.


       -reset Reset  all  settings  to  the factory defaults. This option is a
              fast  and  easy  way  to  restore  all  settings  to  a   useful
              configuration,  especially  when  there are problems with one or
              more settings.  Settings are stored  in  a  text  file  such  as


              Show  cursor  location  in  pixel  coordinates rather than graph

       -ctor  Trace constructor calls

       -dtor  Trace destructor calls

              Trace curve combobox operations

              Trace measure combobox operations

              Trace screen refreshes

              Trace image scanning

Environment variables

              To  start  up  the  date/time  converter  from  within   Engauge
              Digitizer,  this  environment  variable must be set to the shell
              command that runs a  javascript-capable  browser.  Examples  are
              ’firefox’, ’konqueror’, ...

              If set, this specifies the directory containing the user manual.
              This option, like the ’-manual’ command line option, should  not
              be needed on a Debian installation.


       The  program  is  documented  quite  nicely  in the HTML user guide and
       tutorial, available under /usr/share/doc/engauge-digitzer/usermanual or
       from Help within the running program.
