Description
The ROI (region of interest) is the rectangle colored box that appears on the
screen when you select certain tools from the program sequence.
Some of the IP (Image Processing) tools work on the entire image and others allow you to define
where you want them to work. The ROI box allows you to tell
that tool where to work. The ROI box can be placed anywhere on the
Viewer window and can be resized and rotated as needed.
Note this tool will change the ROI programmatically.
The "EditROI" options will be overwritten when the tool is run/selected

When the ROI box is selected it will
typicall turn red and 10 smaller boxes will be placed around the ROI so you can
resize and rotate it.
If you hold CTRL down when resizing the
ROI will maintain a perfectly square shape.
If you hold Shift while rotating it will
rotate in 15 degree increments.
If you right-click inside the ROI it
will display the ROI property page which include such attribute as.
- The "Color" and "Highlight color"
options allow you to change the color of the ROI box.
- The Thickness allows you to change the
width of the ROI box line. The higher the number the thicker
the line.
- Coordinate system controls how the
ROI understands where it is on the screen.
