我有一個 XFDF 文件包含一些注釋但不包含字段，我想知道它是否能夠使用 PDFBox 將這些注釋導入 PDF 文件我嘗試在 Acrobat Reader DC 中將 XFDF 導入 PDF 并成功顯示導入的注釋。然而，通過在 PDAcroForm 中使用函數 importFDF 顯示注釋并不成功。它只導入字段而不導入注釋。下面是我的樣本 XFDF    <?xml version="1.0" encoding="UTF-8" ?><xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve"><fields /><annots>    <ink page="0" rect="414.755559,308.987191,564.755559,365.356617" color="#000000" flags="print" name="a74a6f8a-4149-d913-6ee6-34ba434bc254" title="annotationTest" subject="Signature" date="D:20190808175939+08'00'" creationdate="D:20190808175827+08'00'">        <inklist>            <gesture>415.23,342.9;415.23,342.9;417.62,345.77;422.4,349.11;441.98,357.24;456.79,361.53;470.17,364.88;471.12,364.88;471.6,362.97;468.74,355.8;464.44,346.25;456.79,333.35;440.07,314.72;432.91,310.9;429.56,309.46;429.09,309.46;427.65,312.81;427.65,316.15;429.09,319.02;432.91,322.36;445.81,324.27;454.41,323.8;463,320.45;472.56,317.11;488.32,315.2;499.31,315.68;505.52,318.06;509.82,320.45;514.12,322.36;514.6,322.36;515.55,322.36;517.94,322.36;526.06,322.36;530.36,322.36;535.14,322.36;539.44,322.36;541.83,322.36;542.78,322.36;543.26,322.36;544.69,322.36;546.6,322.84;548.51,322.84;549.47,322.84;550.42,323.8;552.34,325.23;553.29,325.71;554.25,326.66;554.72,327.14;556.63,328.1;559.98,329.05;564.28,330.48</gesture>        </inklist>    </ink>或推薦的任何其他圖書館？非常感謝。
