目前使用的是java aspose-words-23.9-jdk17.jar试用版，能否自动调整文本字号

[SalesDhorde]

我需求是将源文档的内容只要是文本的就将字号调大，最终生成一个新的文档。这种方式是不是逐步遍历这个文档对象模型树,将每个节点序列化后写入输出流。举个例子：我的节点有 图片1:300M 段落1:50M 图片2:300M 段落2:50M 当程序遍历到段落2的时候，内存中是不是只会加载图片1，段落1，图片2的部分基本信息，而不是全部加载微信图片_20230919151702.png (100.8 KB)

@SalesDhorde, 您可以使用 DocumentVisitor 更改字体大小，如下例所示：

InputStream srcStream = new FileInputStream("aa.docx");
OutputStream destStream = new FileOutputStream("ccccc.docx");

Document srcDoc = new Document(srcStream);
srcDoc.accept(new FontChanger(2));
srcDoc.save(destStream, SaveFormat.DOCX);

srcStream.close();
destStream.close();

public static class FontChanger extends DocumentVisitor {
    private double mFontSizeFactor = 1;
    private void changeFont(Font font)
    {
        double newFontSize = font.getSize() * mFontSizeFactor;
        font.setSize(newFontSize);
    }

    public FontChanger(double fontSizefactor)
    {
        mFontSizeFactor = fontSizefactor;
    }

    /// <summary>
    /// Called when a FieldEnd node is encountered in the document.
    /// </summary>
    @Override
    public int visitFieldEnd(FieldEnd fieldEnd)
    {
        //Simply change font name
        changeFont(fieldEnd.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a FieldSeparator node is encountered in the document.
    /// </summary>
    @Override
    public int visitFieldSeparator(FieldSeparator fieldSeparator)
    {
        changeFont(fieldSeparator.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a FieldStart node is encountered in the document.
    /// </summary>
    @Override
    public int visitFieldStart(FieldStart fieldStart)
    {
        changeFont(fieldStart.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a Footnote end is encountered in the document.
    /// </summary>
    @Override
    public int visitFootnoteEnd(Footnote footnote)
    {
        changeFont(footnote.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a FormField node is encountered in the document.
    /// </summary>
    @Override
    public int visitFormField(FormField formField)
    {
        changeFont(formField.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a Paragraph end is encountered in the document.
    /// </summary>
    @Override
    public int visitParagraphEnd(Paragraph paragraph)
    {
        changeFont(paragraph.getParagraphBreakFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a Run node is encountered in the document.
    /// </summary>
    @Override
    public int visitRun(Run run)
    {
        changeFont(run.getFont());
        return VisitorAction.CONTINUE;
    }

    /// <summary>
    /// Called when a SpecialChar is encountered in the document.
    /// </summary>
    @Override
    public int visitSpecialChar(SpecialChar specialChar)
    {
        changeFont(specialChar.getFont());
        return VisitorAction.CONTINUE;
    }
}
