Project description
[](https://travis-ci.org/trufont/uharfbuzz)
[](https://ci.appveyor.com/project/trufont/uharfbuzz/branch/master)
## uharfbuzz
Streamlined Cython bindings for the [HarfBuzz][hb] shaping engine.
### Example
```python
import uharfbuzz as hb
import sys
with open(sys.argv[1], 'rb') as fontfile:
fontdata = fontfile.read()
text = sys.argv[2]
face = hb.Face.create(fontdata)
font = hb.Font.create(face)
upem = face.upem
font.scale = (upem, upem)
hb.ot_font_set_funcs(font)
buf = hb.Buffer.create()
buf.add_str(text)
buf.guess_segment_properties()
features = {"kern": True, "liga": True}
hb.shape(font, buf, features)
infos = buf.glyph_infos
positions = buf.glyph_positions
for info, pos in zip(infos, positions):
gid = info.codepoint
cluster = info.cluster
x_advance = pos.x_advance
x_offset = pos.x_offset
y_offset = pos.y_offset
print(f"gid{gid}={cluster}@{x_advance},{x_offset}+{y_offset}")
```
