如何使用「PDF 表单填写」？How do I use the PDF Forms tool?

在「PDF 表单填写」中，选择或拖入文件，然后点击「填写并导出」按钮即可。加密的 PDF 会提示输入密码（出现「打开密码」栏和「打开」按钮），输入密码并点「打开」后再继续。In the PDF Forms: Choose or drop your files, then click "Fill & export". For an encrypted PDF, the page asks for its password (a Password field and an Open button appear) — enter it, click Open, then continue.

支持哪些控件？Which field types are supported?

文本框（含多行与长度限制）、勾选框（on/off）、单选组、下拉框和列表框（多选用 | 分隔）。签名域和按钮不能用文本填写。选项名不对或域名不存在时会列出全部错误，不会导出半成品。Text fields (including multi-line and length limits), checkboxes (on/off), radio groups, dropdowns and list boxes (separate multiple choices with |). Signature fields and buttons cannot be filled with text. If a field name or option is wrong, every problem is listed and nothing is exported.

“拼合”是什么？What does Flatten do?

把填好的值画进页面并移除表单域，导出的文件看起来一样，但不能再编辑。It draws the filled values into the page and removes the form fields, so the file looks the same but can no longer be edited.

能填中文吗？Can I fill in Chinese text?

可以。值里含中文时会嵌入中文字体子集，保证文本框正常显示。Yes. When a value contains Chinese characters a subset of a Chinese font is embedded so the field displays correctly.
