- On the right pane, in the Info panel, select or clear the Show Trim Size check box to display the PDF Trim box as a black dashed line.
When you select the Show Trim Size option (which only displays page content inside the file's trim box), Smart Review automatically resizes the page to fit the window—for example, if you were previously zoomed in on the page.
When you switch from Single View or Compare View to Spread View, the trim size is automatically displayed. When you switch from Spread View to Single View or Compare View, the Show Trim Size option is cleared by default. When you switch from Single View to Compare View or vice versa, the settings that are in use for the Show Trim Size option are honored. You can then select or clear the Show Trim Size option in the current view, as desired.
