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:
|
|
|
|
1. Install Wine from your favorite package manager. On Fedora that's `dnf install wine`.
|
|
|
|
2. And `mingw-w64` compiler.
|
|
With `brew` on macOS, you can have it like `brew install mingw-w64`.
|
|
On Fedora, with `dnf install mingw32-gcc-c++`, or `dnf install mingw64-gcc-c++` for the
|
|
64-bit Windows.
|
|
|
|
3. Install cross-compiled dependency packages. Alternatively see [^1] below.
|
|
On Fedora that would be `dnf install mingw32-glib2 mingw32-cairo mingw32-freetype`
|
|
for 32-bit, or `dnf install mingw64-glib2 mingw64-cairo mingw64-freetype` for 64-bit.
|
|
|
|
5. `NOCONFIGURE=1 ./autogen.sh && mkdir winbuild && cd winbuild`
|
|
|
|
6. Run `../mingw32.sh` for 32-bit build, or `../mingw64.sh` for 64-bit. This configures
|
|
HarfBuzz for cross-compiling. It enables Uniscribe backend as well.
|
|
|
|
7. `make`
|
|
|
|
Now you can use hb-shape using `wine util/hb-shape.exe` but if you like to shape with
|
|
the Microsoft Uniscribe,
|
|
|
|
8. 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](https://en.wikipedia.org/wiki/Uniscribe)).
|
|
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,
|
|
|
|
9. `WINEDLLOVERRIDES="usp10=n" wine util/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)
|
|
|
|
|
|
[^1] Download and put [this](https://drive.google.com/open?id=0B3_fQkxDZZXXbWltRGd5bjVrUDQ)
|
|
in your `~/.local/i686-w64-mingw32`. Then replace all the instances of
|
|
`/home/behdad/.local/i586-mingw32msvc` and `/home/behdad/.local/i686-w64-mingw32`
|
|
with `<$HOME>/.local/i686-w64-mingw32` on that folder.
|
|
(`<$HOME>` replace it with `/home/XXX` or `/Users/XXX` on macOS)
|
|
You shouldn't replace the instances of those inside binary files.
