engauge-digitizer - interactively convert a bitmap graph or map into numbers
This manual page documents briefly the engauge
command from the
- -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
- 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 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.
- Show cursor location in pixel coordinates rather than graph
- Trace constructor calls
- Trace destructor calls
- Trace curve combobox operations
- Trace measure combobox operations
- Trace screen refreshes
- Trace image scanning
- To start up the date/time converter from within Engauge
Digitizer, this environment variable must be set to the shell command that
- 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.
