+# libtiff如何集成到系统Rom
+## 准备源码工程
+本库是基于OpenHarmony-v3.2-Beta1版本，在RK3568开发板上验证的，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)。
+### 准备系统Rom源码
+系统源码获取请参考：[OpenHarmony源码下载](https://gitee.com/openharmony/docs/blob/OpenHarmony-v3.2-Beta2/zh-cn/release-notes/OpenHarmony-v3.2-beta1.md)
+### 增加构建脚本及配置文件
+- 下载本仓库代码
+  ```
+  cd ~
+  git clone git@gitee.com:openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+- 三方库目录结构
+  ```
+  tpc_c_cplusplus/libtiff  #三方库xerces-c的目录结构如下
+  ├── adapted               #存放三方库适配需要的代码文件
+  ├── docs                  #存放三方库相关文档的文件夹
+  ├── BUILD.gn              #构建脚本，支持rom包集成
+  ├── bundle.json           #三方库组件定义文件
+  ├── README.OpenSource     #说明三方库源码的下载地址，版本，license等信息
+  ├── README_zh.md        
+  ```
+- 将三方库拷贝到OpenHarmony源码的third_party目录下
+  ```
+  cp ~/tpc_c_cplusplus/libtiff ~/openharmony/third_party -rf
+  ```
+### 准备三方库源码
+```
+cd ~/openharmony/third_party/libtiff    #进入三方库目录
+git clone https://gitlab.com/libtiff/libtiff.git -b v4.3.0 --depth=1    #下载三方库源码
+```
+## 系统Rom中引入三方库
+准备完三方库代码后，我们需要将三方库加入到编译构建体系中。标准系统编译构建可以参考文档[标准系统编译构建指导](https://gitee.com/openharmony/docs/blob/OpenHarmony-3.2-Beta1/zh-cn/device-dev/subsystems/subsys-build-standard-large.md)
+我们默认三方库是属于OpenHarmony的thirdparty子系统，如果需要自己定义子系统参考文档[如何为三方库组件中添加一个三方库](https://gitee.com/openharmony-sig/knowledge/blob/master/docs/openharmony_getstarted/port_thirdparty/README.md)
+新增需要编译的组件,在OpenHarmony源码的vendor/hihope/rk3568/config.json文件中，新增需要编译的组件，如下代码段所示，在thirdparty子系统下面新增libtiff组件
+
+```
+    {
+      "subsystem": "thirdparty",
+      "components": [
+        {
+          "component": "musl",
+          "features": []
+        },
+        {
+          "component": "libtiff",
+          "features": []
+        }
+      ]
+    }
+
+```
+## 系统Rom中引入三方库测试程序
+如果需要编译测试用例，在OpenHarmony源码的vendor/hihope/rk3568/config.json文件,对应组件的features中打开编译选项，如下
+```
+    {
+      "subsystem": "thirdparty",
+      "components": [
+        {
+          "component": "musl",
+          "features": []
+        },
+        {
+          "component": "libtiff",
+          "features": ["enable_libtiff_test=true"]
+        }
+      ]
+    }
+```
+## 编译工程
+在OpenHarmony源码根目录下
+```
+cd ~/openharmony
+```
+- 选择平台
+  ```
+  hb set    #hb set 命令会列出所有可选平台，这里我们选择rk3568
+  ```
+- 执行编译
+  ```
+  hb build --target-cpu arm      #编译32位系统
+  hb build --target-cpu arm64    #编译64位系统
+  ```
+- 生成文件的路径，可执行文件和库文件都在out/rk3568/thirdparty/libtiff目录下，同时也打包到了镜像中
+## 运行效果
+将编译生成的库和测试文件放到板子上运行，为避免每次将文件推入设备都烧录整个镜像，我们使用hdc_std工具将文件推到开发板上
+- 首先将hdc_std工具编译出来
+  工具编译出来所在路径out/sdk/ohos-sdk/windows/toolchains/hdc_std.exe
+  
+  ```
+  hb set     #源码根目录下使用hb set 选择产品ohos-sdk
+  hb build   #然后编译
+  ```
+- 将工具拷贝到Windows，可以为工具目录配置环境变量，也可以在工具所在目录打开windows命令行
+- 将原生库测试需要的所有文件打包成libtiff.tar,并拷贝到windows下
+- 将文件推送到开发板，在windows命令行进行如下操作
+  ```
+  hdc_std shell mount -oremount,rw /     #修改系统权限为可读写
+  hdc_std file send libtiff.tar /         #将文件包推入开发板
+  hdc_std shell                          #进入开发板
+  tar xvf libtiff.tar                     #解压
+                                         #注意需要将库拷贝到/system/lib 或者/system/lib64目录下
+  ```
+- 运行测试程序
+  测试用例非常多，这里演示其中几个用例，如下图
