PURPOSE
Please read the Release Notes to see version comparisons and download older version(s) if needed.
Origin's standard Digitizer Tool allowed you to import an image of a line, symbol or line + symbol plot and recreate the data behind the plot. This was a handy tool for graphing and analyzing data for which you did not have the original dataset(s).
Origin's newer Enhanced Digitizer builds on this basic functionality by adding faster and more powerful methods of capturing data points. In addition to the standard manual, point-by-point digitizing method, you can interactively pick points using either of four automated methods. Easily remove extraneous points by dragging out a box around them. All point-picking and removal operations are made easier by your ability to zoom in on a portion of the graph.
The Enhanced Digitizer supports digitizing of points in the 2D Cartesian, Polar and Ternary coordinate systems. For all coordinate systems, digitizing multiple axes graph is also supported by setting group for lines, because each group can have independent axis settings.
INSTALLATION
Save the attached EnhancedDigitizer.opx, drag and drop it onto the Origin workspace (must have Origin 9.1 SR1 + ) to install it, then access this tool by selecting "Tools:Digitizer..." from top menu.
OPERATION
Refer to the Enhanced Digitizer tutorial or watch this video.
KEY FEATURES
Image Pre-Processing
- Rotate image
- Remove background
- Remove gridlines
Data Point Capture
- Manually Pick Points: Pick points by aligning cross-hairs on the data plot and double-clicking with your mouse.
- Auto Trace Line by Points: Pick several lines on a plot and this tool automatically picks the remaining points.
- Auto Pick Points by Grids: Drag out a grid with your mouse and pick points wherever the grid intersects the plot.
- Area Auto Trace: Hybrid method picks points along curve inside of rectangule.
- Boundary-Limited Area Auto Trace: Similar to Auto Trace except that points are created only within the selected area. When the selected area contains uncrossed multiple curves, the results will be put in different lines. Possible to merge the lines if they belong to the same curve.
SUPPORTED COORDINATE SYSTEMS
- 2D Cartesian
- Polar
- Ternary
KNOWN ISSUES
- Remove Gridline may also remove axes. Recommended to set axes prior to removing gridlines.
- May not work for some GIF format images.
