Description

Please document under which conditions PDFont.getFontDescriptor() may return null and what can be done to calculate the text ascent/descent. Clearly, this should be possible to calculate as the text ends up getting rendered.

Background information:

I have a PDF file (credit card statement, so it cannot be shared easily) that contains an embedded PDType3Font called "C0EX06Q0". When I invoke PDFont.getFontDescriptor() I get null.

I have a screenshot of what it looks like.
