将PDF/A转换为PDF格式

将PDF/A文档转换为PDF

将PDF/A文档转换为PDF意味着从原始文档中移除PDF/A限制。Document类具有方法’RemovePdfaCompliance’，用于从输入/源文件中移除PDF合规信息。之后Save输入文件。

void ConvertPDFAtoPDF()
{
    std::clog << "PDF/A to PDF convert: Start" << std::endl;
    String _dataDir("C:\\Samples\\Conversion\\");
    String infilename("sample-pdfa.pdf");
    String outfilename("PDFAToPDF_out.pdf");

    auto document = MakeObject<Document>(_dataDir + infilename);

    // Remove PDF/A compliance information
    document->RemovePdfaCompliance();

    // Save updated document
    document->Save(_dataDir + outfilename);
    std::clog << "PDF/A to PDF convert: End" << std::endl;
}

该信息还会在您对文档进行任何更改时删除（例如，添加页面）。在以下示例中，添加页面后输出文档失去了PDF/A合规性。

void ConvertPDFAtoPDFAdvanced()
{
    std::clog << "PDF/A to PDF convert: Start" << std::endl;
    String _dataDir("C:\\Samples\\Conversion\\");
    String infilename("sample-pdfa.pdf");
    String outfilename("PDFAToPDF_out.pdf");

    auto document = MakeObject<Document>(_dataDir + infilename);
    // Adding a new (empty) page removes PDF/A compliance information.

    document->get_Pages()->Add();
    // Save updated document
    document->Save(_dataDir + outfilename);
    std::clog << "PDF/A to PDF convert: End" << std::endl;
}
