Select a Region
• Choose the desired selection tool from the Edit menu button.
• Rectangular and Elliptical ROI: To define a rectangular or elliptical type of ROI, start with the
upper-left corner of the desired region and drag the mouse downward and to the right until the
desired area is marked.
• Polygonal ROI: To define a polygonal ROI, click the left mouse button in the upper left area of
the desired ROI, then continue clicking the left mouse button to encompass the remainder of the
desired ROI. When the area is defined, right mouse click anywhere on the image to join the first
and last points and close the ROI.
• FreeForm ROI: To define a ROI with the mouse pointer, keep the left mouse button pressed and
draw around the region of interest. Lift the mouse button to automatically complete and enclose
the area.
• Magic Wand ROI: To mark the ROI automatically on the image, click once inside the region of
interest and the software marks that area by identifying the edges. Zoom in on the image to get a
better outline of the ROI. The Magic Wand slider allows adjustment of the sensitivity of the area
defined by the Magic Wand.
Apart from Analysis features, Copy also uses the region of interest tool. Copy will copy the selected
region to the clipboard. If there is no selected region, the entire image will be copied.
Adjust a Region
If the selection is not quite right, move or resize it without having to start over:
• To change height or width: drag any of the white corner markers to the desired size.
• To move the selection: click on and drag the interior of the ROI to the new location.
Cancel a Region
• Click once anywhere on the image outside of the current ROI. The selection markers will
disappear. Once a region has been cancelled it cannot be undone.
