如果你希望使用C++的库来进行文件格式转换,你可以考虑使用LibreOffice的UNO API(Universal Network Objects Application Programming Interface)来实现。下面是一个简单示例:
#include <com/sun/star/bridge/XUnoUrlResolver.hpp>
#include <com/sun/star/frame/XComponentLoader.hpp>
#include <com/sun/star/frame/Desktop.hpp>
#include <cppuhelper/bootstrap.hxx>
using namespace com::sun::star::uno;
using namespace com::sun::star::frame;
int main() {
// 初始化UNO运行环境
OUString serviceManagerPath = "/usr/lib/libreoffice/program/fundamentalrc";
OUString unoIniPath = "/usr/lib/libreoffice/program/bootstrap.ini";
std::string unoArgv = "--accept=socket,host=localhost,port=2083;urp;";
std::vector<std::string> argv;
argv.push_back(unoArgv);
css::uno::Reference<css::uno::XComponentContext> xContext = cppu::bootstrap(serviceManagerPath, unoIniPath, argv);
if (!xContext.is()) {
printf("Failed to initialize UNO runtime environment!\n");
return -1;
}
// 获取桌面服务
css::uno::Reference<css::frame::Desktop> xDesktop(xContext->getServiceManager()->createInstanceWithContext("com.sun.star.frame.Desktop", xContext));
if (!xDesktop.is()) {
printf("Failed to get desktop service!\n");
return -1;
}
// 构造输入和输出文件URL
OUString inputUrl = "file:///path/to/input.doc";
OUString outputUrl = "file:///path/to/output.pdf";
// 构造转换选项
css::uno::Sequence<css::beans::PropertyValue> conversionOptions;
// 设置输出格式为PDF
css::beans::PropertyValue outputFormat;
outputFormat.Name = "FilterName";
outputFormat.Value <<= OUString("writer_pdf_Export");
conversionOptions.push_back(outputFormat);
// 调用桌面服务进行文件格式转换
css::uno::Reference<css::frame::XComponentLoader> xComponentLoader(xDesktop, css::uno::UNO_QUERY);
css::uno::Reference<css::frame::XStorable> xStorable(xComponentLoader->loadComponentFromURL(inputUrl, "_blank", 0, conversionOptions));
if (xStorable.is()) {
xStorable->storeToURL(outputUrl, css::uno::Sequence<css::beans::PropertyValue>());
printf("文件转换成功!\n");
} else {
printf("文件转换失败!\n");
return -1;
}
return 0;
}
请确保你已经安装了LibreOffice并设置了正确的头文件和库文件路径。此示例使用了C++ UNO(Universal Network Objects)来与LibreOffice交互,需要相应的头文件和库文件支持。
这只是一个简单的示例代码,如果你需要更复杂的功能或对错误处理有更详细的控制需求,你可能需要进一步完善代码。
