同步操作将从 OpenHarmony/third_party_harfbuzz 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。
For the development of HarfBuzz, the Microsoft shaping technology, Uniscribe, as a widely used and tested shaper is used as more-or-less OpenType reference implementation and that specially is important where OpenType specification is or wasn't that clear. For having access to Uniscribe on Linux/macOS these steps are recommended:
You want to follow the 32bit instructions. The 64bit equivalents are included for reference.
Install Wine.
dnf install wine
.Install mingw-w64
compiler.
dnf install mingw32-gcc-c++
dnf install mingw64-gcc-c++
apt install g++-mingw-w64
brew install mingw-w64
If you have drank the meson
koolaid, look at .ci/build-win32.sh
to see how to
invoke meson
now, or just run that script. Otherwise, here's how to use the
old trusty autotools instead:
a) Install dependencies.
dnf install mingw32-glib2 mingw32-cairo mingw32-freetype
dnf install mingw64-glib2 mingw64-cairo mingw64-freetype
b) Configure:
NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild
../mingw-configure.sh i686
../mingw-configure.sh x86_64
Now you can use hb-shape
by (cd win32build/util && wine hb-shape.exe)
but if you like to shape with the Microsoft Uniscribe:
Bring a 32bit version of usp10.dll
for yourself from C:\Windows\SysWOW64\usp10.dll
of your
Windows installation (assuming you have a 64-bit installation, otherwise
C:\Windows\System32\usp10.dll
) that it is not a DirectWrite proxy
(for more info).
Rule of thumb, your usp10.dll
should have a size more than 500kb, otherwise
it is designed to work with DirectWrite which Wine can't work with its original one.
You want a Uniscribe from Windows 7 or older.
Put the DLL in the folder you are going to run the next command,
WINEDLLOVERRIDES="usp10=n" wine hb-shape.exe fontname.ttf -u 0061,0062,0063 --shaper=uniscribe
(0061,0062,0063
means abc
, use test/shaping/hb-unicode-decode to generate ones you need)
