how to edit a PDF file

來源: 於 2004-05-18 12:02:14 [舊帖] [給我悄悄話] 本文已被閱讀：次

can a pdf file be edited? I don't mean to create a pdf file. I download acrobat professional 6.0, but seems it just added three buttons in MS Word to convert Word file to pdf file, and I don't see any function to edit an existing pdf file.

Thanks for any help!
