 Straight line measurement

This function measures the distance of a line drawn on an image and the angle deviation for the horizontal axis.

After selecting this icon from the Tool window, hold down the left mouse button on an image and draw a line.

As a line is drawn its length and angle from the horizontal axis will be continuously updated (displayed) in the Line Measurement status box.

To log the line measurement to disk, click on “Log to DDE.” The distance line drawn will disappear after each line measurement is drawn if under Selection, the Measuring Tools option: Only one Linear Measurement selection is checked on, other wise all distance lines will be left on the current image. The units displayed and stored to disk will correspond to units that have been setup in the calibration distance menu.

Using the Text Tool, the line measurement data can be stamped on an image (see Text Tool).
