问题 Is there any way to make the border of a cell with dotted line (e.g _ _ _ _ _ _ _ _ _ _ _ _) instead of solid line ( e.g ________________ ) in iText-5.0.1???? 回答1: could you rig something like adding new paragraphs with small height and text="---------" PdfPCell Cell = new PdfPCell(new Paragraph("------")); Cell.Height = 0.2f; You can also draw the borders yourself using a PdfPCellEvent. There are different layers to add to. See the API here: http://api.itextpdf.com/com/itextpdf/text/pdf

问题 I have been struggling with this issue for a long time now. I am simply trying to implement a stamping feature using iText7.NET. The issue first arises from transparency.
