如何更改docxjs中的默认文档边距

const docx = require("docx");

const customMargins = {
  top: docxPgMargin cmToInches(1), // 默认 1 英寸
  bottom: docxPgMargin cmToInches(1),
  left: docxPgMargin cmToInches(1.5), // 可根据需要更改
  right: docxPgMargin cmToInches(1.5),
};

const customPageSize = {
  size: docx.PageSize.A4,
  orientation: docx.Orientation.PORTRAIT,
};

const doc = new docx.Document({
  pagesize: customPageSize,
  margins: customMargins,
});

const paragraph = new docx.Paragraph("Hello World!");
doc.addParagraph(paragraph);

// Save as DOCX
docx.Packer.toBuffer(doc).then((buffer) => {
  fs.writeFileSync("MyDocument.docx", buffer);
});

// Save as PDF
docx.Packer.toBuffer(doc).then((buffer) => {
  const pdf = require("pdfkit");
  const writeStream = fs.createWriteStream("MyDocument.pdf");
  const doc = new pdf();
  doc.pipe(writeStream);
  doc.addPage();
  doc.fontSize(25).text("Hello World!", 0, 0);
  doc.end();
});

function cmToInches(cm) {
  return cm / 2.54;
}
