如何在 iText 中将段落与不同的块对齐

Question

我需要帮助来证明以下段落的对齐方式：

Font certifyFont = new Font(Font.TIMES_ROMAN, 16);
Paragraph certifyParagraph = new Paragraph();
certifyParagraph.setAlignment(Element.ALIGN_JUSTIFIED_ALL);

Chunk certifyText = new Chunk("This is to certify that  ", certifyFont);
certifyParagraph.add(certifyText);

Font nameFont = new Font(Font.TIMES_ROMAN, 16, Font.BOLD);
Chunk nameText = new Chunk("NAME ", nameFont);

Font workingFont = new Font(Font.TIMES_ROMAN, 16);
Chunk workingText = new Chunk("has been working in the company since the ", workingFont);

doc.open();
doc.add(certifyText);
doc.add(nameText);
doc.add(workingText);
doc.close();

我尝试将段落对齐为两端对齐、居中和靠右，但对齐方式似乎并未反映在 PDF 文件中。

在您的代码中，您正在创建一个 Paragraph 对象 certifyParagraph 并为其定义对齐方式，但您从未将其添加到文档中。相反，您要添加三个不同的 Chunk 对象，分别命名为 certifyText、nameText 和 workingText.

我已经调整了您的代码，以便将这三个 Chunk 对象添加到 Paragraph 对象，并且将 Paragraph 对象添加到文档而不是单独的（无对齐）块：

Paragraph certifyParagraph = new Paragraph();
certifyParagraph.setAlignment(Element.ALIGN_JUSTIFIED_ALL);

Font certifyFont = new Font(Font.TIMES_ROMAN, 16);
Chunk certifyText = new Chunk("This is to certify that  ", certifyFont);
certifyParagraph.add(certifyText);

Font nameFont = new Font(Font.TIMES_ROMAN, 16, Font.BOLD);
Chunk nameText = new Chunk("NAME ", nameFont);
certifyParagraph.add(nameText);

Font workingFont = new Font(Font.TIMES_ROMAN, 16);
Chunk workingText = new Chunk(" has been working in the company since the ", workingFont);
certifyParagraph.add(workingText);

doc.open();
doc.add(certifyParagraph);
doc.close();
