> PDFBox should support embedded font types, most prominently the Adobe
> CFF/Type2 (aka Type1C) font type. The desired functionality includes both
> glyph metrics (for PDF text extraction using
> org.apache.pdfbox.util.PDFTextStripper) and glyph painting (for PDF rendering
> using org.apache.pdfbox.pdfviewer.PageDrawer).
> I have implemented the basics of Adobe CFF/Type2 font specification. If the
> other project members find my work substantial, I would like to see it
> incorporated into FontBox/PDFBox projects. Please see the attached patch
> files.
> Design considerations. A PDF FontFile3 stream can be parsed into CFFFont
> objects by class CFFParser. CFFFont contains a map of glyph names to Type2
> charstrings, which can be converted to Type1 charstrings by class
> CharStringConverter and rendered by class CharStringRenderer. Glyph metrics
> is attained by formatting the result as AFM by class AFMFormatter, which
> plugs nicely with existing PDFBox infrastructure. Glyph painting is attained
> by formatting the result as PostScript Type1 font by class
> Type1FontFormatter, which can be loaded via java.awt.Font#createFont(int,
> InputStream).
> The current implementation does not support synthetic CFF fonts nor CID-keyed
> CFF fonts. Also, the conversion of certain Type2 features (stemming, hinting,
> flex) is missing.
