Select the shape of ROI to be drawn.
Draw the ROIs.
Click the Finish button. The toolbar will be closed.
Hold the Ctrl button and select multiple ROI objects by mouse.
Click on the
Connect button.All ROIs which overlap will be merged together.
This command deselects all defined ROIs within the currently opened document.
This command copies all defined ROIs to clipboard. Use command in the image contextual menu to paste the copied ROIs to a different image document.
This command removes all ROIs touching the image border.

Creates any number of regions of interest. The following tool bar appears:
Figure 478.
There are the following tools available:
Pointing tool The Pointing tool switches the current tool to a pointer mode. Then the cursor has similar functionality as if the ROI editor was is closed.
Rectangle Enables you to draw rectangular ROI.
Ellipse There are several ways to draw an elliptical shape. Invoke the pull-down menu and select between them: Circle, 3pt Circle, Npt Circle, Ellipse, 4pt ellipse. Please see View > Analysis Controls > Annotations and Measurements 
for details about the tools.
Polygon You can draw a polygon by the standard Polygon tool.
Bezier Enables you to draw a Bezier curve. Use the tool in the same way as the Polygon tool (just place the points around the area of interest and finish it by right-click).
Auto Detect, 
Auto Detect All Use the Auto Detect tool to let the system detect an area of similar pixels. A continuous area () or more isolated areas () can be created. Please see ROI > Auto Detect ROI for details about the basic autodetect tool.
Draw Holes A ROI can contain holes as well. Use the Draw Holes button to switch any of the drawing tools to the “holes” mode.
Connect This button merges multiple overlapping ROIs together.
Clear This button erases all ROIs.
Undo, 
Redo These buttons enables the user to browse the history of changes made on ROIs.
Caution
The Redo button cannot be used after some manual change is made. For example, if you pressed the Undo button several times to go backward in the history of changes, the Redo button enables you to go forward and revert the change. However, if you press the button and then make some change such as adding a new ROI, the button gets disabled and the “forward history” is deleted.
Help Pressing this button opens this help page.
Finish When you are finished with creating ROIs press this button to close the editor.

The ROI Editor enables the user to modify the region of interest. It contains a selection of drawing tools of the Binary > Binary Editor command. See Binary Editor for description of all tools.

Use this command to draw a rectangular ROI in the current image.
(requires: Automatic Measurement)
Use this command to draw a square ROI in the current image.
(requires: Automatic Measurement)
Use this command to draw a circular ROI in the current image.
(requires: Automatic Measurement)
Click and drag to draw the inner circle, then release the mouse button and click and drag again to draw the outer circle. Release the mouse button again and the ring shaped ROI is created in the current image.
(requires: Automatic Measurement)
Use this command to draw an elliptic ROI in the current image.
(requires: Automatic Measurement)
Use this command to draw a polygonal ROI in the current image.
(requires: Automatic Measurement)
Use this command to draw a bezier ROI in the current image.
(requires: Automatic Measurement)
This command will use an auto-detection algorithm to determine borders of an object within the image. It switches mouse cursor to the ROI auto-detection mode. A ROI is created after user interaction.
See Mouse Wheel.
(requires: Automatic Measurement)
This command copies the binary image to the ROI.
(requires: Automatic Measurement)
This command moves the binary image to the ROI.
(requires: Automatic Measurement)
This command enables you to convert ROIs of the current image to binary layer(s).
(requires: Automatic Measurement)
This command moves the ROI to current binary image.
(requires: Automatic Measurement)
Swaps current binary image with Measurement ROI image.

(requires: Automatic Measurement)
Replaces all ROIs on the current image with the new ROIs created from the current graticule. This function is recommended to use only with rectangular, circle or simple circle graticule types.
(requires: Automatic Measurement)
If you have deleted some ROIs, this command renumbers all the remaining ones so that numbering starts from 1 and is continuous. Only numbers greater than the deleted ones are renumbered.
(requires: Automatic Measurement)
This command displays labels of defined ROI in the current document.
(requires: Automatic Measurement)
This command creates a new image document which contains data only from selected ROI. When more ROIs are selected, each of them creates a separate document.
