问题 I was under the impression that it is now possible to copy AcroFields using PdfCopy. In the release notes for iText 5.4.4.0 this is listed as possible now. However, when I try to do so it appears all the annotations (I think I am using that term correctly, still fairly new to iText...) for the fields are stripped out. It looks like the fields are there (meaning I can see the blue boxes that indicate an editable field), but they are not editable. If I try to bring the PDF up in Acrobat I get a

问题 Using itextsharp I am trying to tile a single (large) page pdf document (called import document) into a new document where this page is split into several DIN A4 pages (called output document). But I want to draw a border around the DIN A4 pages of the output and only add a smaller than A4 size part of the import document. For clarification please see the picture: On the left is the import doc in size A3 which is like two A4 pages side-by-side (black dotted line). This shall be split to A4

问题 I'd like to add a Paragraph of text to pages in 2 columns. I understand that MultiColumnText has been eliminated. I know I can create column 1, write to it, and if there is more text create column 2 and write to it. If there is still more text, go to the next page and repeat. However I always end up with either: a long chunk of text orphaned in the left column. a full left column and partially used right column. How can I format my content in 2 columns while reducing white space, such as

问题 Currently I'm extracting the text of PDF's with the itextsharp tool (in VB.net). I'd like to be independent of other tools / libraries as I can't give them to others along my programm.

So there is an algorithm for extracting text. Long answer: PDF is not a WYSIWYG
