> **Tip**
>
> For extracting lines, circles, arcs, and parallel lines, you can directly click and draw on the image to add them.
> For other functions, the system will first check whether the modules above the current position have output the corresponding data before determining if they are available for addition. For example, if you are at the 6th function module in the workflow and want to add a point-to-point distance function, but none of the modules 1-5 have output any points, clicking the point-to-point distance quick function module will not work.
> When the modules above have output points, selecting the point-to-point distance quick function module will draw all valid points on the image. You can then simply use the mouse to select the points you want to measure.

**Best Fit:** After zooming in or out on the image with the mouse, you can click this operation to quickly adjust the image to the best display effect, meaning all images will be contained within the image area and scaled to the most appropriate size proportionally.
**Zoom In:** Enlarge the image.
**Zoom Out:** Reduce the image.
**Lock/Unlock ROI:** When in the locked state, the mouse cannot adjust or move the ROI. When in the unlocked state, the mouse can adjust or move the ROI.
**Show Original Image/Drawings:** Displays the source image input to the current module (erasing drawing information), or displays the image with drawings. Drawings here refer to ROI boxes, extracted lines or circles, measured distances, angle values, etc.

**Show All ROIs/Show Current ROI**
Displays the ROIs of all modules in the current workflow, or toggles to show only the ROI of the selected module.
**Filter ROIs**
This operation is available when showing all ROIs. You can filter the ROIs of the modules you want to display by selection.

Example:

**Retest:** Execute a single test again for the current workflow.
