gridROI (Region of Interest) Grid

The ROI Grid is a unique grid ROI.  Each box in the grid has the same properties as an individual square ROI.  That is, a point can be found at the center and ROIs from other tools can key off that point or the dimensions of an individual box in the grid.

When the ROI box is selected it will turn red and 9 smaller boxes will be placed around the ROI so you can resize it. 

If you hold CTRL down when resizing the ROI will maintain a perfectly square shape.

If you right-click inside the ROI it will display the ROI property page.  On the "GeoGrid" page the grid size can be set.  Use the X and Y dimensions to set the number of boxes in the grid.

On the "Display" tab:

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.

The Coordinate system controls how the ROI understands where it is on the screen.
