Behdad Esfahbod 2d8ebcb9d0 [API] One last font-funcs API change
Now that vertical text works correctly, I'm doing a last round
modification of the font-funcs API to simplify.  Expect no more
changes around here.

Design not final yet, and in fact I'm going to change it immediately,

Behdad Esfahbod 0fd8c2f1be [API] Make get_glyph() callback return a boolean
We need to know whether the glyph exists, so we can fallback to
composing / decomposing.  Assuming that glyph==0 means "doesn't exist"
wouldn't work for applications like Pango that want to use different
"doesn't exist" glyph codes for different characters.  An explicit
return value fixes that.

Behdad Esfahbod da97541988 [API] Allow negative font x_scale/y_scale
I was reconsidering whether y should grow down, since all three/four
times I've used this API I was tricked and got that wrong in my use.
So I was very inclined to make y grow down instead of up.  However,
considering that the font space has y up and it would be very confusing
for callbacks to work against that, I decided that what I really want
is for the user to be able to set y_scale to a negative number to imply
that user-space y grows down.

Changing x_scale/y_scale from unsigned int to int allows that, and I've
made pango to use that instead of negating glyph y_offset later.  hb-ft
however still has y group up.  I *guess* that's how FreeType works?
I'm not sure, FreeType docs don't make this clear...

I'm happy with the resolution :-).

Behdad Esfahbod c57d454acc Rename all private sources and headers to C++ files
So we can liberally use the simple features of C++ that parts of the
codebase is already using.

Behdad Esfahbod 9417c1c0d2 [API] Make hb_face_reference_table() return empty blob instead of NULL
The idea here is that:

  - Like pretty much all other API in harfbuzz, user does not have to
    check for NULL.

  - In any caller code, the case of missing table should be handled
    exactly the same way that a too-short table is handled.  Turning
    a non-existent talbe into a table of size 0 makes the user code
    safer.

Behdad Esfahbod c035812feb [API] Rename hb_face_get_table() to hb_face_reference_table()
That correctly reflects the reference ownership transfer happening.

Behdad Esfahbod af02933739 [API] Remove hb_*_get_reference_count()
This was a bizzare piece of API that I inherited from cairo.  It has
been wrong adding them to cairo in the first place.  Remove them before
someone uses them!

Behdad Esfahbod 19c0eab8cf Add getters for all setter APIs
One in particular is not a straight getter: hb_font_unset_funcs() is
special because of the specific needs of the lifecycle management of
the user_data object.

Behdad Esfahbod 99d9ef785f Write hb_face_create_for_data() in terms of hb_face_create_for_tables()
Fixes lack of head_table initialization in create_for_tables() also.
2010-05-20 15:47:49 +01:00
Behdad Esfahbod 0a4399ca22 Fix scale issues
hb_font_set_scale() now sets the value to be used to represent a unit
pixel.  For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6).  For 10px in 16.16 you would set it to
(10 << 16).  This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.
