Robert Meyer commented on PDFBOX-1646:
--------------------------------------
Ok, these issues can be closed but some of the changes made in this patch are
relevant. Maybe not necessarily for the bounding box but definitely the
getGlyphNameFromCode from SID method. I apologize for not being quicker with
this but I am putting the finishing touches to subsetting Type 1 fonts in FOP
so I am currently unable to return to this at present. You can close both and I
will come back to it and re-submit a patch under a different issue once I have
a better idea of what is required by FOP.
> [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.
