推荐答案

您不必更改页面事件，而必须更改页面大小.

Instead of using a page event, you have to change the page size.

例如:

Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, new 
FileOutputStream(outPutDirectory + indexID + ".pdf"));
document.open();
// Add some content in portrait
document.setPageSize(PageSize.A4.rotate());
document.newPage();
// Add some content in landscape
document.close();

请注意以下事实:页面大小仅在下一页上改变. setPageSize()和newPage()的顺序很重要.

Be aware of the fact that the page size only changes on the next page. The order of setPageSize() and newPage() is important.
