The Engauge Digitizer tool assists in interactively extracting numbers from images of graphs. Conceptually, it is thus the opposite of a graphing tool that converts data points to graphs. It provides assistance in enhancing the image quality and matching the data points. Engauge Digitizer is used by individuals such as grad students and researchers as well as engineers and employees in large government and commercial organizations for processing single files but also managing databases of thousands of image files.Features of Engauge Digitizer include:Automatic grid line removalAutomatic point and axis matchingAutomatic curve tracingImage processing for separating important details from background informationA wizard providing an interactive tutorial to explain the basic stepsMultiple coordinate systems in the same image can be digitized in advanced modeCubic spline interpolation between points gives more accurate curves with fewer pointsHandling of cartesian, polar, linear and logarithmic graphsSupport for drag-and-drop and copy-and-pasteContext-sensitive help, user manual and tutorials explaining every featurePreview windows to give immediate feedback while modifying settingsAutomated line and point extraction to rapidly digitize data
