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 'Info' 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 "yes" if the font is embedded in the PDF file
sub "yes" if the font is a subset
uni "yes" if there is an explicit "ToUnicode" map in the PDF file
(the absence of a ToUnicode map doesn't necessarily mean that
the text can't be converted to Unicode)
User Experiences
e.g. links to AQuA/SCAPE/Hackathon issues that use the tool
- A fine set of tools. I used pdffonts to help validate my work on dynamic dependencies (see http://arxiv.org/abs/1111.0735).
