Detecting Reversed PostScript Hints

[delve]

Hey Everyone,

I'm stumped. Does anyone here know how to detect reversed postscript hints using Python in FontLab?

Here's what I tried:

Code:

font = fl.font

for index in range(len(fl.font)):
glyph = fl.font[index]
vhw = glyph.vhints.width
if len(vhw) < 0:
print glyph.name, vhw

I find there are two things wrong here (but I don't know how to fix them).
1. FL py reports width as not being an attribute of hhints
2. len(vhw) < 0 returns nothing even when I know those instances are present

Any suggestions would be appreciated.

Thanks,
Delve Withrington

My python slave ;-) knows, but will he answer? Keep in mind that ghost hints have values -20 and -21 for top and bottom ghosts respectively.

Hehe. Let me know if your python slave will tell.

You're right about the ghost hints. I expect those would show up as well, but more specifically I'm trying to tease out those reversed hints left over from legacy font data generated with Fontographer.

Thanks,
D
