Freehand tools employ a click and drag method for drawing an ROI, make sure that when using a freehand tool you continue holding down the cursor until you finish drawing the ROI.

  1. Click the image with the tool equipped to start creating an ROI.

  2. Move the cursor to another section of the image, and click again to finalize the shape of the ROI. In this example, a box shape was used for the annotation shape.
