This function allows you to adjust the surface of the scan to be horizontal in those cases
where the retina is highly tilted. Click Auto Straighten to automatically correct the image.
The slider controls, number field, and up/down arrows are used to manually correct the
image by adjusting the X and Z axes. Click Reset to Zero to undo your corrections. The reset
buttons (see figure above) located above each field allow you to reset X and Z axes
separately. Figure 8-50 illustrates before and after Auto Straighten has been applied. The
left figure shows a tilted image, and the right figure shows the straightened image.
