Measure surface-area/circumference

To measure surface-area and circumference with the (Area Measurement) tool, left-click once to initiate the drawing. Left-click around the edges of the objects to trace the contours. Use as many or as few points as you wish. The figure is closed automatically, and double-left-click on the last point to end the drawing.

Use the (Edit polyline) tool to adjust the figure after drawing. Upon selecting this tool, red dots will be added where the tracing points has been placed. These can now be dragged into a new position by dragging existing points, new points can be added by clicking where there is no points or removed by pressing ctrl + left mouse click on existing point.

Magic wand

The magic wand is used to automatically detect a figure on the image. To measure surface-area and circumference with the (Magic Wand) tool, adjust the tolerance and max points in the Settings menu. The tolerance is how big a color difference the wand should accept. Too high a value will measure outside the object, too low a value will not measure the whole object. Left-click once on the object and the contours will automatically be traced.

After the measurement has been made, the line can be edited by using the (Edit polyline) tool. The individual points will show up in red, and they can be dragged to tune the figure.

By clicking at the line where no red dot present, a new point will me bade. By holding down “Ctrl” on the keyboard and clicking an existing point, it will be removed.

Note: The magic wand will sometimes be inaccurate, due to lack of contrast and little in the pictures. This tool is mainly used for measuring on drawn images

 

Tip: Always start measuring by left-clicking once and end the measuring by double-left-clicking.
