PDF object noise inside `font.name`

[SuperCowProducts]

The line font.name = "Type3 (15 0 R)" (instead of font.name = "Type3") stopped my level 2 headings from being generated in this PDF:

Mechanics _ Definition, Examples, Laws, & Facts _ Britannica.pdf

It's probably a bug in the PDF extractor, but as the author said the tool is modular so workarounds are easy: hopefully this helps out others before they wonder what happened to some of their headings...

Here is how I got it working correctly:

pf='Mechanics _ Definition, Examples, Laws, & Facts _ Britannica.pdf'
rm -rf recipe.toml
pdfxmeta -p 3 -a 1 "$pf" 'The origins and foundations of mechanics' >> recipe.toml
pdfxmeta -p 3 -a 2 "$pf" 'History' >> recipe.toml
sed -i -E 's/ \(15 0 R\)//g' recipe.toml
pdftocgen -v < recipe.toml "$pf" > toc 
pdftocio < toc "$pf"

Hmm, actually doing it this way should cause less problems: Nope, The Editors of Encyclopaedia Britannica still appears instead of The origins and foundations of mechanics - I can easily fix that one off with PDF4QT though.

pf='Mechanics _ Definition, Examples, Laws, & Facts _ Britannica.pdf'
rm -rf recipe.toml
pdfxmeta -p 13 -a 1 "$pf" 'Motion of a particle in one dimension' >> recipe.toml
pdfxmeta -p 13 -a 2 "$pf" 'Uniform motion' >> recipe.toml
sed -i -E 's/ \(15 0 R\)//g' recipe.toml
pdftocgen -v < recipe.toml "$pf" > toc 
pdftocio < toc "$pf"
