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:
There are the following tools available:

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.

Enables you to draw rectangular ROI.

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.

You can draw a polygon by the standard Polygon tool.

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).


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.

A ROI can contain holes as well. Use the Draw Holes button to switch any of the drawing tools to the “holes” mode.

This button merges multiple overlapping ROIs together.

This button erases all ROIs.


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.

Pressing this button opens this help page.

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.

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.

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.
This command enables you to convert ROIs of the current image to binary layer(s).
Swaps current binary image with Measurement ROI image.
Note
You can get general overview of working images by using View > Thumbnails.

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.
The current ROI(s) are inverted and this inversion is inserted into the image as a new ROI.
