Re: Why cannot generate xml metrics file????? bug?
Hi,
Thanks for Rafal Maczewski!
It works!
Can you tell me why should in.readTTFUShort() instead
of in.readTTFShort()??
What is the defference between the 2 methods?

Hi,
There is a small bug in the TTFFile.java that prevents
xml metrics file
generation for some fonts. The patch is included
below. I've checked that
this fixes the problem with mingliu.ttf file (I don't
have the mingliu.ttc
collection).
Hope this helps,
Rafal Maczewski

Hello,
The difference is that readTTFUShort reads unsigned integers, and
readTTFShort reads signed integers. So if the first bit is set, the signed
version of the function will return negative value and the unsigned version
will return positive value above 32767. The difference is important for
large font files where the offsets exceed 32767 bytes.
