I’d do the simple thing and output an all 0's one, garbage in, garbage out. A slightly better fix is to use the equivalent font extents from head table, but this particular code has access to the CFF table only and not the rest of the font tables, so that is not easy to pull (CFF table was shoehorned to OpenType, it is a standalone font format and duplicate some data available elsewhere in OpenType and the code here is written on the assumption accessing CFF table is enough, which is generally true). Calculating extents from the glyphs is slow, so I wouldn’t do this. The issue should be reported to the font developers as well. -- You are receiving this mail because: You are the assignee for the bug.
