Hello,
I have a few questions about this method, I am looking to obtain
the table information to find the values for substitution tables so that
I can input the correct value for value when I create a hb_feature_t.
I figured the hb_ot_layout_table_get_feature_tags is the method call
that would work, this method requires hb_face_t.
I am using freetype in this project and I have used freetype to create a
FT_Face, and to save myself the headache I used hb_ft_create_referenced,
and from what I read that should return *hb_face_t, it does but as
incomplete and using GDB to debug the code even if I type cast to
(hb_face_t) still prints incomplete and ptype also returns an incomplete
struct.
I noticed that the struct is defined in hb_face.h as incomplete, and the
full struct is defined in hb-face-private.hh, which does not seem to be
used directly by the header files I included in my program.
After some forcing by recompiling harfbuzz with some changes, I have
been able to extract the tags from the hb_face but this is not a good
solution for me, I am certain I am missing something tiny and would love
some insight.
I have including the following headers hb.h, hb-ft.h and hb-ot.h, the
code is compiling and I have passed into the gcc command -lharfbuzz and
-I/usr/include/harfbuzz, and also double checked that the *.h files are
present in /usr/include/harfbuzz and that libharfbuzz is present in the
lib folder.
thanks
