PDF font extraction

PDF font extraction used to be a simple thing until 2001. Most PDF files created after 2001 have only partial character sets, but most older PDF files have full type 1 or other font files. Mirko Scholz recommends the use of pdftosrc, part of the PDFTeX package. Alternately, one can use Acrobat3 (*not* higher versions) and output a PostScript file from a PDF file. Inspect the PostScript file to find the fonts, usually located between BeginResource and EndResource lines (or the line with "cleartomark"). You may have to add a header line (example: %!PS-AdobeFont-1.0: AmasisMT (001.003)). The PFA file (in case of type 1) needs to be converted to PFB using t1utils, a free package. Remember that no metrics (AFM, PFM) file can be extracted from a PDF file! Several utilities exist (e.g., Crossfont) that automatically generate a basic PFM file. See also the discussion here.
