Behdad Esfahbod 60fbb36096 [Vertical] GPOS is always done with horizontal origin 2011-05-19 18:46:15 -04:00
Behdad Esfahbod 8b38faeede More vertical
Starting to get there, but not without yet another round of changes.

I think I know wheere to go now.

Behdad Esfahbod 7e2c85de30 [API] Vertical support, take 2
I like this API *much* better.  Implementation still incomplete, but
horizontal works.

Behdad Esfahbod 744970af4d [API] Add support for vertical text
Design not final yet, and in fact I'm going to change it immediately,
but this is an standalone change for itself.

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 a513dbcf73 [API] Change signature of get_contour_point and get_kerning ffuncs
get_contour_point now takes glyph id before point_index.

get_kerning now takes a vector to fill-in.

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 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 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.
