正确的方法来禁用PDF的提交表单输入

Question

我试图禁用pdf文档的提交表单输入。 我是这样做的： PdfStamper stamper = new PdfStamper(reader, out, '\0', false);

是的，它有效，但我讨厌这个恼人的对话This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document. 当我打开pdf。

如何禁用显示此对话框？ itext版本2.1.7。 试图用chrome和firefox打开（adobe read plugin）。

解决方案： 只需要删除用户权限并启用表单展平。 PdfReader reader = new PdfReader(dao.getFile(id)); reader.removeUsageRights(); PdfStamper stamper = new PdfStamper(reader, out); stamper.setFormFlattening(true);
