engauge-digitizer - interactively convert a bitmap graph or map
into numbers
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 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.
- -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 $HOME/.qt/engaugerc.
- -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
- 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.
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.
