libvips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。

在lycium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
cd lycium ./build.sh libvips -
三方库头文件及生成的库
在lycium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
libjpeg-turbo/arm64-v8a libjpeg-turbo/armeabi-v7a glib/arm64-v8a glib/armeabi-v7a libffi/arm64-v8a libffi/armeabi-v7a pcre2/arm64-v8a pcre2/armeabi-v7a libexpat/arm64-v8a libexpat/armeabi-v7a libpng/arm64-v8a libpng/armeabi-v7a libjpeg-turbo/arm64-v8a libjpeg-turbo/armeabi-v7a zlib/arm64-v8a zlib/armeabi-v7a
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
其中xxx代表的是库名，本库即为libvips。
-
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 target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/pcre2/${OHOS_ARCH}/lib/libpcre2-8.a ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/pcre2/${OHOS_ARCH}/lib/libpcre2-posix.a ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libjpeg-turbo/${OHOS_ARCH}/lib/libturbojpeg.a ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libpng/${OHOS_ARCH}/lib/libpng.a) target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libffi.so.8 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libjpeg.so.62 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libpng16.so.16 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libz.so.1 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libvips-cpp.so.42 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libvips.so.42 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libgio-2.0.so.0 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libglib-2.0.so.0 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libgmodule-2.0.so.0 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libgobject-2.0.so.0 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libgthread-2.0.so.0 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libintl.so.8 ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libexpat.so.1) # 将三方库的头文件加入工程中 target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libvips/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libpng/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libffi/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libjpeg-turbo/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/glib/${OHOS_ARCH}/include/glibconfig.h ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/glib/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/glib/${OHOS_ARCH}/include/glib-2.0 ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libexpat/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/pcre2/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/zlib/${OHOS_ARCH}/include)
测试三方库
三方库的测试使用原库自带的测试用例来做测试，准备三方库测试环境
进入到构建目录执行可执行程序运行测试用例（arm64-v8a-build为构建64位的目录，armeabi-v7a-build为构建32位的目录）
