如何将图像添加到 itext 5.2.1 中的标题？
As the picture shows, the logo should fill the header.
如图所示，徽标应填充标题。

Try to use it:
尝试使用它：
Image logo = Image.getInstance("/image.gif");
logo.setAlignment(Image.MIDDLE);
logo.scaleAbsoluteHeight(20);
logo.scaleAbsoluteWidth(20);
logo.scalePercent(100);
Chunk chunk = new Chunk(logo, 0, -45);
HeaderFooter header = new HeaderFooter(new Phrase(chunk), false);
header.setAlignment(Element.ALIGN_CENTER);
header.setBorder(Rectangle.NO_BORDER);
document.setHeader(header);
of course object document is: Document document = new Document();
当然对象文档是：Document document = new Document();

You already posted a quite similar questionsome days ago. In my answer to that question, I pointed to this other answer. Instead of adding text to the header table as described there, you can add an Image.
几天前您已经发布了一个非常相似的问题。在我对那个问题的回答中，我指出了另一个答案。您可以添加一个图像，而不是像那里描述的那样向标题表添加文本。
