Question

使用以下代码复制带注释的页面时，iText 7.1.0会复制/Popup注释，“原始”和重复之间的唯一区别是，有一个/Parent条目和其他没有。

不幸的是，没有丢失/Parent的那个已在/Annots字典的/Page列表中注册。如何让iText不复制注释或至少注册带有/Parent条目的注释？对奇怪行为的任何解释？

import com.itextpdf.kernel.pdf.*;
import java.io.IOException;

public class CopyPdfTest {
    public static void main(String[] args) throws IOException {
        PdfDocument inputDoc = new PdfDocument(new PdfReader("input.pdf"));
        PdfWriter writer = new PdfWriter("output.pdf");
        writer.setCompressionLevel(0);
        PdfDocument outputDoc = new PdfDocument(writer);

        for (int i = 1; i <= inputDoc.getNumberOfPages(); i++) {
            inputDoc.copyPagesTo(i, i, outputDoc);
        }

        inputDoc.close();
        outputDoc.close();
    }
}

input.pdf
