Problems with TTX for Mac

Ramiro Espinoza

Hi there,

I am having problems trying to decompile a TTF font with the mac version of TTX (2.0b1)

Traceback (most recent call last):
File "Titaantje:Users:just:code:fonttools:Tools:ttx", line 11, in ?
File "Titaantje:Users:just:code:fonttools:Lib:fontTools:ttx.py", line 250, in main

fontTools.ttLib.TTLibError: unknown format for OS/2 table: version 3

Any idea? Is it maybe because my TTX version is outdated?

I downloaded the latest version (2.3) at:
http://sourceforge.net/projects/fonttools/files/

Then I read the install.txt inside folder 'documentation'. There it says:

Installation
For Windows and MacOS there are easy-to-use TTX installers. The rest if this
document is meant for people who want to use TTX/FontTools from the source.

Problem is, I can't find the mac installer in any of the folders.

Can anyone give me a hint?

Thanks in advance.

the command-line implementation of version 2.2 is included with AFDKO. I have encountered similar errors when using (the standalone application version of) 2.0b1 but not with 2.2.

ADFKO is available from http://partners.adobe.com/public/developer/opentype/afdko/index.html

Hi there,

I have AFDK installed but for the moment I only use it for hinting. Thanks for the advise, I will try to use it from ADFK.

Cheers. R.

Hi Agisaak,

Can you give me an example on how to run TTX from AFDK? I've been checking the AFDK and I could not find a mention about it.

TIA.

It needs to be invoked from the command-line.

In the terminal, type

/Developer/FDK/Tools/osx/ttx

and you should get a brief description of the options available from the command line. Your simplest way of using it is to follow the above with the path to a file (either an .otf, .ttf, or .ttx file).

(n.b. the above path is what is present on my system -- depending on how you installed FDK and the version, yours might be different, but look for a folder called Tools in your installation. You can simplify the above by including the fdk tools in your PATH variable).

It worked. Thanks!
