Well, the decision whether you are using `full hinting' or not is
given by the load flags used in `FT_Load_Glyph'.  This is *external*
information given by Chrome itself!  FreeType overrides this only for
the very small class of `tricky' fonts which don't display correctly
otherwise; this can be tested with `FT_IS_TRICKY'.

Am I missing something?

The demo programs leave out all error checking for simplicity.  You
have to take care of that by yourself.

I strongly suggest that you get acquainted with (a) compiling and
linking in general, and (b) how to use a debugger like `gdb' or a GUI
front-end to it to identify the source code location where the program
crashed.

However, this mailing list is not the right place to do that, sorry.

I successfully compiled the example in this way:
$gcc example1.c -I/home/parth/anaconda3/include/freetype2
-L/home/parth/anaconda3/lib -lfreetype -lm
But,
when I run $./a.out font sample-text
for checking output it shows Segmentation fault (core dumped).
Please help.

[ft-devel] How to determine if horizontal hinting is happening?

2018-02-15 Thread Adam Goode 
Hi,

I am working on a Chrome bug (crbug.com/740385) related to subpixel
positioning and hinting.

There is currently an issue where glyphs do not get positioned correctly in
all cases, and to solve this problem I need to enable subpixel positioning.

This works, except when horizontal hinting is enabled ("full hinting" in
xft enables this). In this case, letters get smeared badly.

https://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html suggests that
I should do subpixel positioning if I am not hinting horizontally, which
matches with my understanding.

Therefore, I would like to programatically determine if horizontal hinting
is happening and base the subpixel positioning decision on this
information. But I have not been able to figure out how to do this. Is
there a way that avoids needing to know the internals of the engines?


Thanks,

Adam

You are missing an -L flag to specify the directory where libfreetype
is located.
