#### Adding Tools

The tool icons are located above the image area.

There are two ways to add a tool to an image:

1. Click on the tool icon.
2. Click and drag a tool icon into the image area, then adjust the region of interest (ROI) by grabbing one of the ROI's four anchor points and sizing the ROI as needed.

##### Region of Interest (ROI)

- All AutoVISION tools have an ROI except Match Strings, String Format, and Logic.
- A tool will only execute its function within its own ROI.
- Larger ROIs require more processing time.
- ROIs of different tools can overlap and still function correctly.
- Some ROIs can rotate. ROI rotation is available for the following tools:

- Decode Tool
- OCR Tool
- Count Tool
- Presence / Absence Tool
- Measure Tool
