> An EPS has only a single BoundingBox but a PDF contains a MediaBox, CropBox, BleedBox, TrimBox and ArtBox.
> For a description, see http://www.prepressure.com/pdf/basics/page-boxes
> For an advertisement, ArtBox is the content of the ad; TrimBox is the size that an application like Scribus should use to place the ad; BleedBox is the size that applications like Scribus should clip to; CropBox is the size for proofing the ad for viewers but is not supposed to be used by applications like Scribus; MediaBox is for complete pages including items that will be physically trimmed from the final product like crop marks, registration marks, slugs, etc.
> Some viewers like "gv" have an option to let you override the displayed area.
> The poppler package has the capability also, for example, pdftops crops to the CropBox by default but has a -nocrop option to use the MediaBox instead.
> On Linux, you can check the values with pdfinfo in the poppler package with the -box option.
