|
|
The Engauge Digitizer tool accepts image files
|
|
(like PNG, JPEG and TIFF) containing graphs,
|
|
and recovers the data points from those graphs.
|
|
The resulting data points are usually used as input
|
|
to other software applications.
|
|
Conceptually, Engauge Digitizer is the opposite of
|
|
a graphing tool that converts data points to graphs.
|
|
The process is shown below - an image file is imported,
|
|
digitized within Engauge, and exported as a table of
|
|
numeric data to a text file.
|
|
Work can be saved into an Engauge DIG file.

|
New features already added to Engauge:
|
|
</p>
|
|
<p>
|
|
- Grid lines are displayed for fine adjustments of the axis points that define the coordinate systems
|
|
- Automated line and point extraction rapidly digitizes data
|
|
- Image processing for separating important details from background information
|
|
- Undo/redo of all operations means recovering from mistakes and experimenting with options is painless
|
|
- Installers for Windows and OSX operating systems, and repository packages for Linux make installation easy
|
|
- Wizard provides an interactive tutorial to explain the basic steps
|
|
- Wizard creates a checklist guide to interactively leads user through steps from file import to file export
|
|
- Cubic spline interpolation between points gives more accurate curves with fewer points
|
|
- Axes Checker briefly highlights the axes when they are defined or modified, to reveal entry mistakes
|
|
- Graph coordinates can be specified as date and time values, or as degrees, minutes and seconds
|
|
- File import and data export by drag-and-drop and copy/paste
|
|
- Test suite for regression testing minimizes code breakage as new features are added
|
|
- Multiple coordinate systems in the same image can be digitized in advanced mode
|
|
- Axes with only one known coordinate (floating axes) can be digitized in advanced mode
|
|
- Geometry Window displays geometric information about the selected curve
|
|
- Curve Fitting Window fits a polynomial function to the selected curve
