[Fontforge-devel] Generate fonts from SFDs to TTFs with scripts: with traditional kern table.

Hi,

As $subject. I updated the packaging method of Liberation Fonts which
SRPM of liberation-fonts contain SFDs and it generates TTFs when the
SRPM is built into RPM.

The generation from SFDs to TTFs are done with fontforge scripts that
with simple two lines Open() and Generate(). However, for backward
compatibility I want to include traditional kern table.

I was taught to tick the checkbox 'old style kern' in options window
when I click 'generate font' in fontforge UI. Would this step could be
also implemented in fontforge scripts so I could automate this?

Thank you very much for reading.

Regards, kaio

Could you kindly give me some idea which version of the fontforge
started to support this (fmflags)? I tried on 20090224 but it seems did
not functioning.

FYI, my scripts as follows:

$ cat sfd2ttf.pe
Print( "    ")
Print( "Generating ttf from sfd sources...")
Print( "----------------------------------")
Open($1)
Generate($1:r + ".ttf" ,"fmflags&0x800")
Print( "    ")

It should be:
Generate($1:r + ".ttf", "", 0x800)

The second parameter is "bitmaptype", "fmflags" should be the third and
it isn't a string.
I think "fmflags&0xXXX" in the documentation means you have to sum the
flags together (so, if you want to set 0x800 and 0x200, "fmflags" would
be the some of both.) Since I don't know what these numbers mean, I just
use python interpreter as a calculator (0x800+0x200 is 2560, which will
generate 'kern' and 'TeX' tables).

 Khaled
