## Engauge Digitizer - Measure Geometry Window

The measure geometry window shows angles, distances and areas for the currently active measure (which is displayed in the Digitize toolbar). Regions in the window may be selected and then exported to other applications by either copying or dragging. Control-C is used for copying.

At each point, the angle is defined between the line from the previous point, and the line to the next point.

At each point, the distance is defined as the length of the line to the next point.

The functional area of the measure is the area calculated by integrating the area under the curve. The polygonal area of the measure is the area within the polygon through all of the points in the measure.

Until the coordinates are defined by axes points or a scale bar, the measure geometry window will show information in the screen coordinates, which are in units of pixels. Afterwards, the geometry measurements are in the measure coordinates.

An example of a measure geometry window is shown below. The FuncArea may be ignored since it is not useful for a measure. The PolyArea is the area inside the closed polygon. The distances along the measure, in either direction, are shown, along with the angle at each point, and the coordinates of each point.
