Adding a Freehand ROI on an Image

Introduction

Using ROI tools, you can draw a freehand annotation on an image to highlight a region of interest on an image. Freehand shapes measure arbitrary points on an image.

Steps

1. Right-click the image to display the image context menu.
2. Select Annotations > Freehand ROI.
3. Click and drag to create a freehand ROI.
4. Do one of the following:

   If you want to ...	Do this ...
   Enclose the freehand ROI shape.	Close the ROI shape by joining the end point of the shape to the starting point.
   Create a freehand line.	Release the left-mouse button when you are finished drawing the freehand line. The length of the line displays.

Note:

When you slowly create a freehand ROI, the length measurement might be longer because Synapse counts the micro mouse movements.
