I don't have time to analyze this in detail, but, as Lawrence
observed, you *must not* rely on internal implementation details of
FreeType.

In general, FreeType is not suited at all as a library to manipulate
PostScript files.

Regardless of that, the correct way is to extract the 'loca' table
with `FT_Load_Sfnt_Table` and parse the table by yourself.  This is
rather trivial to do, so it shouldn't be much work – and doing so
makes your code future-proof.

I think your life would be a lot easier if you stopped making
assumptions about the internal implementation of FreeType.

No it isn’t.

Hi All,

In file ttpload.c there is a  function tt_face_load_loca and below line filling 
those values.
if ( FT_FRAME_EXTRACT( table_len, face->glyph_locations ) ).
I don't know how to fix this and looking for further information/assistance.

Appreciate all the help!!.

Thanks,
Ankit Jain

Yes, these are consumed by printers.

Do you have to write PostScript files? How are these being consumed? By a 
printer? By another graphics app? There may be a way to avoid PostScript.

The difference might be FT_Long* versus FT_Byte*.

Hi,

I need help in knowing how we are getting different glyph_locations in freetype 
version 2.0.9 and 2.10.0.
I understand both are very different version initially we were using
2.0.9 version and creating the font data for post script(.ps file) we are using 
these location to write the data in post script file as post script has 
limitation in writing the number of bytes and after a certain threshold(65519 
characters) it adds a new line.
The threshold was getting in hit in older version and output was fine but after 
upgrades the locations are not what we were getting in 2.0.9.

Please find attached source code and glyph_location from both the versions. I 
am using arial font for testing.

Appreciate help any other pointers to move further from here.
