+# libass 集成到应用hap
+
+本库是在RK3568开发板上基于OpenHarmony3.2 Release版本的镜像验证的，如果是从未使用过RK3568，可以先查看[润和RK3568开发板标准系统快速上手](https://gitee.com/openharmony-sig/knowledge_demo_temp/tree/master/docs/rk3568_helloworld)。
+
+## 开发环境

+- [准备三方库构建环境](../../../tools/README.md#编译环境准备)
+- [准备三方库测试环境](../../../tools/README.md#ci环境准备)
+
+## 编译三方库
+
+- 下载本仓库
+
+  ```shell
+  git clone https://gitee.com/openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+
+- 三方库目录结构
+
+  ```
+  tpc_c_cplusplus/thirdparty/libass  #三方库libass的目录结构如下
+  ├── docs                              #三方库相关文档的文件夹
+  ├── HPKBUILD                          #构建脚本
+  ├── SHA512SUM                         #三方库校验文件
+  ├── README.OpenSource                 #说明三方库源码的下载地址，版本，license等信息
+  ├── README_zh.md   
+  ```
+
+- 将libass拷贝至tools/main目录下
+
+  ```
+  cd tpc_c_cplusplus
+  cp thirdparty/libass tools/main -rf
+  ```
+
+- 在tools目录下编译三方库
+
+  编译环境的搭建参考[准备三方库构建环境](../../../tools/README.md#编译环境准备)
+
+  ```
+  cd tools
+  ./build.sh libass
+  ```
+
+- 三方库头文件及生成的库
+
+  在tools目录下会生成usr目录，该目录下存在已编译完成的32位和64位三方库
+
+  ```
+  libass/arm64-v8a   libass/armeabi-v7a
+  ```
+
+- [测试三方库](#测试三方库)
+
+## 应用中使用三方库
+
+- 在IDE的cpp目录下新增thirdparty目录，将编译生成的库拷贝到该目录下，如下图所示：
+
+  &nbsp;![thirdparty_install_dir](pic/libass_install_dir.png)
+
+- 拷贝动态库到`\\entry\libs\${OHOS_ARCH}\`目录：
+
+  动态库需要在`\\entry\libs\${OHOS_ARCH}\`目录，才能集成到hap包中，所以需要将对应的so文件拷贝到对应CPU架构的目录：
+
+  &nbsp;![thirdparty_install_dir](pic/libass_install_dir2.png)
+
+- 在最外层（cpp目录下）CMakeLists.txt中添加如下语句：
+
+  ```
+  #将三方库加入工程中，libass是对应的三方库名
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/fribidi/${OHOS_ARCH}/lib/libfribidi.so.0)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/harfbuzz/${OHOS_ARCH}/lib/libharfbuzz.so.0)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libass/${OHOS_ARCH}/lib/libass.so.9)
+  #将三方库的头文件加入工程中，libass是对应的三方库名
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/fribidi/${OHOS_ARCH}/include)
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/harfbuzz/${OHOS_ARCH}/include)
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libass/${OHOS_ARCH}/include)
+  ```
+  ![libass_usage](pic/libass_usage.png)
+
+## 测试三方库
+
+三方库的测试使用原库自带的可执行文件来做测试
+
+进入到构建目录,再进入test目录,执行
+```
+# 测试时需要把Unbutu中的usr/share/fonts打包推送到ohos设备中,放在ohos设备同一路径中
+./test testass.png sub1.ass 0.03
+```
