When you place an Adobe PDF file, you specify which page you want to import. You also choose how to crop the artwork by selecting a Crop To option:

Bounding Box

Places the PDF page’s bounding box, or the minimum area that encloses the objects on the page, including page marks.

Art

Places the PDF only in the area defined by a rectangle that the author created as placeable artwork (for example, clip art).

Crop

Places the PDF only in the area that is displayed or printed by Adobe Acrobat.

Trim

Identifies the place where the final produced page will be physically cut in the production process, if trim marks are present.

Bleed

Places only the area that represents where all page content should be clipped, if a bleed area is present. This information is useful if the page is being output in a production environment. Note that the printed page may include page marks that fall outside the bleed area.

Media

Places the area that represents the physical paper size of the original PDF document (for example, the dimensions of an A4 sheet of paper), including page marks.
