Xpdf

= Description = Xpdf is an open source PDF viewer that includes command-line information extractor and font analyzer utilities. The following utilities are particularly relevant to digital preservation:


 * pdfinfo: prints the contents of the â€˜Infoâ€™ dictionary (plus some other useful information) from a Portable Document Format (PDF) file. 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)


 * pdffonts: lists the fonts used in a Portable Document Format (PDF) file along with various information for each font

The following information is listed for each font:

name the font name, exactly as given in the PDF file (potentially

including a subset prefix)

type the font type

emb â€œyesâ€ if the font is embedded in the PDF file

sub â€œyesâ€ if the font is a subset

uni â€œyesâ€ if there is an explicit â€œToUnicodeâ€ map in the PDF file

(the absence of a ToUnicode map doesnâ€™t necessarily mean that

the text canâ€™t be converted to Unicode)
