John Hewson commented on PDFBOX-2565:
-------------------------------------
I cleaned up TTFSubsetter and have implemented subsetting for
Type0/CIDFontType2 fonts - i.e. TrueType fonts. The file size of
the"EmbededFonts" example has now been reduced form 217KB to 11KB.
It's worth pointing out the PDFBox's APIs were designed for parsing and
modifying PDFs, but are not ideal for creating PDFs from scratch when the
subsetting of fonts is involved. We always require a PDFont to be valid and
usable: the font embedding procedure therefore occurs twice, once for the
initial full font, and once for the subset. While seemingly wasteful, this
doesn't really add a significant overhead and avoids a drastic upheaval of the
font APIs.

>
> Now that PDFBOX-922 is fixed, we have working TTF embedding. However, the
> entire font is embedded, which is rather large. We already have a
> TTFSubsetter class in FontBox, which is never used, so we should make use of
> it.
