NAME

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

SYNOPSIS

       engauge [options]

DESCRIPTION

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

Startup

       -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 menu

       -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

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

Shutdown

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

Settings

       -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 $HOME/.qt/engaugerc.

Debugging

       -pixels
              Show cursor location in pixel coordinates rather than graph coordinates

       -ctor  Trace constructor calls

       -dtor  Trace destructor calls

       -curvecmb
              Trace curve combobox operations

       -measurecmb
              Trace measure combobox operations

       -refresh
              Trace screen refreshes

       -scanning
              Trace image scanning

Environment variables

       ENGAUGE_BROWSER
              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', ...

       ENGAUGE_USERMANUAL
              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.

SEE ALSO

       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.
