图片标题POI字

Question

我正在尝试使用Apache POI插入图片标题，但我对此没有任何想法。我在用

doc.createParagraph().createRun().addPicture(input, 
Document.PICTURE_TYPE_PNG, "picture.png", 
           Units.pixelToEMU(603), Units.pixelToEMU(226));

插入图片，现在我想为它添加标题，以便能够创建图形表。我试过使用一些样式paragraph.setstyle（“legends”）；但它只改变字体，我不喜欢“header1”（我有模板）。我研究了styles.xml（在我的模板中，我使用word插入图片标题），发现

-<w:style w:type="paragraph" w:styleId="Legenda">
<w:name w:val="caption"/>
<w:basedOn w:val="Normalny"/>
<w:next w:val="Normalny"/>
<w:unhideWhenUsed/>
<w:qFormat/>

所以看起来我只需要将段落w：name w：val设置为“caption”。我说的对吗？我怎么才能够到它？

关于在Word中插入图形表的工作方式，您应该知道的是：

当我们添加标题时，每个标题段都包含一个序列字段{SEQ figure\*ARABIC}。名称“figure”是序列字段的名称。然后，如果要创建一个图形表，word将收集包含这样一个字段的所有段落，以便从这些段落中构建图形表。

到目前为止(ApachePOIVersion3.17)还不提供为图添加标题，也不提供插入或创建图表，至少据我所知是这样。所以我们必须自己使用低级别的CTSimpleField来完成。

  FileOutputStream out = new FileOutputStream("CreateWordTableOfFigures.docx"); 
  document.write(out);
  document.close();
