About comparing files
The Compare feature enables you to view two files at the same time in Smart Review and to compare the differences between the two files. You can also view two revisions of the same file.
Aligning views in Compare mode
When comparing images of different sizes in Compare mode, use the Align Views feature to align a specific point on one image with a specific point on the other image. This is useful when you are comparing two images that are identical except for their page dimensions or positioning on each page—for example, two revisions of the same element.
Rotating a file in Compare mode
When comparing images of different orientations in Compare mode, use the Rotate feature to rotate only one image. This is useful when you are comparing two files that are identical except for their image orientations.
