Harfbuzz 测试程序

Libharfbuzz 严重参考《Harfbuzz-ng API Basic Usage》

#下载源码

wget http://www.freedesktop.org/software/harfbuzz/release/harfbuzz-0.9.10.tar.bz2 || exit 1

#解压

tar xvjf harfbuzz-0.9.10.tar.bz2 && cd harfbuzz-0.9.10/ || exit 1

#配置编译

./configure && make

输入的是ttf字体文件和utf-16。输出Glyphs and Positions.如下：

$ ./src/test ./NotoSansHans-Regular.otf

Opened font file NotoSansHans-Regular.otf: 8364644 bytes long

cluster 0 glyph 0x3276 at (0,0)+(1000,0)

cluster 3 glyph 0x25e5 at (0,0)+(1000,0)

cluster 6 glyph 0x224c at (0,0)+(1000,0)

cluster 9 glyph 0x61f7 at (0,0)+(1000,0)

info->cluster,

info->codepoint,

pos->x_offset,

pos->x_advance,

pos->y_advance

我暂时不太清楚，这些都代表了什么，想像着应该是字的轮廓和位置。类似这样的一个信息：
