To accept that candidate point, press the right arrow key Click on the point to start point matchingĮngauge will display a candidate point. Move the cursor over a typical point in the curve again. If the cursor circle does not change color then adjust the Color Filter settings for this curve Move the cursor over a typical point in the curve. When the Segment Fill line appears, click on it to generate points If a line does not appear then adjust the Color Filter settings for this curve The coordinates are defined by creating axis pointsĬlick on an axis tick mark, or intersection of two grid lines, with labeled coordinatesĬlick on an axis tick mark, or intersection of two grid lines, with labeled coordinates, away from the other axis pointĬlick on an axis tick mark, or intersection of two grid lines, with labeled coordinates, away from the other axis points Each step will show a check when it has been completed. New users are encouraged to use this wizard.įollow this checklist of steps to digitize your image. The wizard can be turned on and off using the Help menu. This wizard also provides a quick summary of the most useful features of Engauge. By following those steps, you can obtain digitized data points in an exported file. This wizard creates a checklist of steps that can serve as a helpful guide. With points only (no lines between points)Įngauge converts an image of a graph or map into numbers, as long as the image has axes and/or grid lines to define the coordinates. What are the names of the curves that are to be digitized? At least one entry is required. If desirable features have been removed from the image, the parameters can be adjusted using Settings / Color Filter, or the original image can be displayed instead using View / Background / Show Original Image. When the parameters have been set correctly, unimportant information (such as grid lines and background colors) has been removed from the filtered images so automated feature extraction can be performed. This filtered image is produced from the original image according to the parameters set in Settings / Color Filter. Why does the imported image look different?Īfter import, a filtered image is shown in the background. To run the Checklist Guide Wizard when an image file is imported, select the Help / Checklist Wizard menu option.

Following these steps should produce a set of digitized points in an output file. This box contains a checklist of steps suggested by the Checklist Guide Wizard.
