Drawing Regions of Interest

You can designate an area of the drop as a "region of interest" (ROI) using the Region of Interest (ROI) tool when in Region view (available on the Navigator). Once a region is defined, your imaging system will zoom in on it and image it separately from the drop the next time that drop is imaged.

The boxes in the ROI tool show you the actual photographable area for each imaging type, which is limited by the constraints of the hardware for each imaging method.

Each imaging type is represented by different colors.

When viewing images in Rock Maker, you can zoom in on a region by selecting it from the Region list box in the Controls area. You can also select custom Imaging Settings for the region.

Drawing a Region of Interest:

1. From the Insert group on the Tools tab in the Images contextual tab set, click the Region of Interest button .
2. Position the crosshairs in the center of the area region of interest.
3. Click and drag the crosshairs across the region until the box is the appropriate size.
4. If you would like to lock the region of interest so that it cannot be moved or deleted, right-click it and select Lock Region.
5. Repeat steps 2 – 4 to define more regions.

 

Deleting a Region of Interest:

• Right-click on the region of interest and select Delete Region, or press the DELETE key.

System Property	Default	Explanation
Experiment plate: Region default optic type	QImaging	The optics selected here will be used as the default optic type. For example, if you have visible imaging with QImaging optics and visible imaging with PixeLINK optics, the imager will automatically use the QImaging optics when you draw a visible light Region of Interest.
