#ENGAUGE DIGITIZER HELP WITH DEFINING AXIS MANUAL#
ENGAUGE_USERMANUAL If set, this specifies the directory containing the user manual. Main steps in using Engauge Digitizer (note that Help User Manual also gives some. I have a graph from a paper on which the origin of the axes is not marked. Automatic grid line removal Automatic point and axis matching Automatic curve tracing Image processing for separating important details from background information A wizard providing an interactive tutorial to explain the basic steps. The first x axis tick is 100, then 200, 300 etc. Debugging ¶ -pixels Show cursor location in pixel coordinates rather than graphĬoordinates -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, thisĮnvironment variable must be set to the shell command that runs a The Engauge Digitizer tool assists in interactively extracting numbers from images of graphs. There are problems with one or more settings. Way to restore all settings to a useful configuration, especially when Settings ¶ -reset Reset all settings to the factory defaults. Documents may alsoīe exported manually using the menu. Shutdown ¶ -export FILE Automatically export the active document at shutdown. Until either the Segments dialog is used, or the Segment Fill button is The axis points may also be digitized manually using the DigitizeĪxis Points mode -lazysegments Postpone scanning for segments that is normally performed during startup, When using Perl or other scripts to digitize many images with known axes The digitized points may require adjustment. For speed, no attempt to rotate the image if it is sideways, so The X axis is assumed to be near theīottom of the image, and the Y axis is assumed to be on the left side of Thenĭigitize axis points assuming the X axis ranges from XMIN to XMAX, and the
axes XMIN XMAX YMIN YMAX Scan the imported file at startup, and locate the X and Y axes. Installed in /usr/share/doc/engauge-digitizer/usermanual and should need Window and exit -manual DIRECTORY Look for the HTML user guide in the specified directory.
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 Image files mayĪlso be imported manually using the menu -open FILE Automatically open the specified Engauge Digitizer document file at Startup ¶ -import FILE Automatically import the specified image file at startup. ScanIt supports multiple views, each with its own set of axis definitions. Engauge Digitizer - Fixing The Axis Points If you are seeing unexpected values for the coordinates produced by Engauge Digitizer, then there probably is a problem with the axis points. This manual page documents briefly the engauge command from the This task is also known as digitizing graph data. Engauge-digitizer - interactively convert a bitmap graph or map into numbers
