iOS PDF parsing Type 1 Fonts metrics
问题 I'm (trying) to write a "PDF to plain text parser" and I'm using pdfKitten as an example. My PDF includes a type1 font included into the "standard 14 fonts". Subsequently the PDF font dictionary does not include keys for "Widths" "FirstChar" "LastChar". I assume, since it is one of the "standard 14 fonts" (actually 2, Courier and Courier-bold), that the iOS framework contains these metrics somewhere. How can I access these metrics? 回答1: The metrics for the standard PDF fonts are usually built
