John Hewson commented on PDFBOX-1646:
-------------------------------------
getGlyphNameFromCode doesn't ad d any new functionality that isn't already
provided by Mapping, you can just etrieve the mapping and look up the name .
These can be cached within FOP if you require frequent access to them.
> [PATCH] Add method for retrieving CFF bounding box from CFFFont class with
> slight refactoring and optimization.

> I have added a method to the CFFFont class to retrieve the bounding box for a
> character determined by an SID as well as retrieving a name. I have also
> slightly modified the existing code so that each sid mapping can be retrieved
> now using the SID as the key from a map. From looking around there are
> several examples of where iterative loops are used using the original mapping
> array:
> CFFFontROS.java:165
> CFFParser.java:876
> I haven't changed those locations yet, but they can be made in a separate
> patch which should boost performance.
> There was a small bit of refactoring done as well just because I now retrieve
> a renderer from two locations. These patches are part of adding OTF CFF
> support to Apache FOP.
