The ´Info’ dictionary contains the following values:

producer
creation date
modification date

In addition, the following information is printed:

tagged (yes/no)
form (AcroForm / XFA / none)
page count
encrypted flag (yes/no)
print and copy permissions (if encrypted)
page size
file size
linearized (yes/no)
PDF version
metadata (only if requested)

options

Specifies the first page to examine. If multiple pages are requested using the "-f" and "-l" options, the size of each requested page (and, optionally, the bounding boxes for each requested page) are printed. Otherwise, only page one is examined.

-l number

Specifies the last page to examine.

-box

Prints the page box bounding boxes: MediaBox, CropBox, BleedBox, TrimBox, and ArtBox.

Prints document-level metadata. (This is the "Metadata" stream from the PDF file’s Catalog object.)

-enc encoding-name

Sets the encoding to use for text output. This defaults to "UTF-8".
