Shape Area Shape tool

Description

The shape tool allows the user to draw a freehand area which is then measured to provide the surface area and perimeter. To use this tool simply drag it onto the image viewer and then left-click on the image and drag the mouse. A line will start being traced on the image. Once you have finished release the mouse button and again left-click anywhere on the image, the line or shape will turn green. You can edit an existing shape by left-clicking on the line of the shape to highlight it red. The individual points that make the shape can then be edited.
