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.
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

To start up the date/time converter from within Engauge
Digitizer, this environment variable must be set to the shell
’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.
