I had a look... the pt size is really 0.24. But the bounding box of the
first font is -1 -11 42 40. So the alleged max height is about 51 x 0.24
= 12,24 units. (1 unit = 1/72 inch)
Nothing else influences this, and the font matrix is the identity matrix.
Have a look at DrawPrintTextLocations.java in the source code download,
this will create a file with the bounds shown. Not the best, but better
than nothing. Showing the exact bounds for type3 fonts is difficult
because it isn't a vector font... even worse, your font has a bug. In
the charprocs of your type3 fonts, the first command should be "d1"
which should be the exact bounding box (and even that is unreliable).
But in your font it isn't, the first command is "q".
Sorry if this is somewhat incomprehensible...
There's also some bug in PDFDebugger that it doesn't display the glyphs.
(But that's just for me)
Re CapHeight, that's another story, as your file doesn't have it.

Not sure how to share on sharehoster, as it appears to be a German site and
I don't speak it. So I dropped a sample file onto my google drive here:
https://drive.google.com/open?id=0B3JXBo1bPbwPbTRYZi0zQTctcTA I had to
modify the pdf slightly to remove customer data. Let me know if you cant
open it for some reason or a better place to share.
Thanks
