itextsharp

问题 This question already has an answer here : “'System.StackOverflowException” in “OnEndPage” event handler (1 answer) Closed 4 years ago . As a continuation to my earlier question I have been trying out the header and footer functions for my PDF. After a little discussion I have changed quite a lot of code on the PdfPageEventHelper class.

问题 I am using the iTextSharp library to sign PDF documents. When I use the standard TSAClientBouncyCastle class to get time stamp from GoDaddy's server ( http://tsa.starfieldtech.com ), the response is an empty stream.

So I wonder what is wrong with my attempt to get a timestamp programmatically using the

问题 Bottom line is I'm using iTextSharp to write out HTML to a PDF -- with an image . Right now, I'm at the latest version of iTextSharp which is 5.5.5.0.

问题 How can I reduce the height of a line break which occurs when a paragraph length is too long for the width of the ColumnText? I've tried the following, as I've seen other questions which answered with this: p.Leading = 0 But this has made no affect. I've also tried increasing the Leading to 100 to see if a larger line break is added, but neither work. SpacingBefore/SpacingAfter doesn't help either: p.SpacingBefore = 0 p.SpacingAfter = 0 How can I reduce this? 回答1: When using a table, you need

问题 I am attempting to rename a checkbox that is subclassed. Let's say the checkbox's name is MyForm.Check1.page0. When I run: reader.AcroField.RenameField("MyForm.Check1.page0", "MyForm.Check1.newName"); The checkbox is renamed just "newName". The subclass information is dropped. I get from the documentation that the subclass cannot be changed, but this was unexpected. According to the documentation: "Renames a field. Only the last part of the name can be renamed. For example, if the original

问题 I know this question has been asked a thousand times, but I am yet to find a straight forward answer. I am relatively new to ITextSharp, so please explain as if you were talking to a toddler.

问题 When I use the alignment of the cell so it works: PdfPCell cell1 = new PdfPCell(new Phrase("Text" , Font)); cell1.HorizontalAlignment = 2; But once the alignment does not work: PdfPCell cell1 = new PdfPCell(); cell1.AddElement(new Phrase("Text 1", Font)); cell1.AddElement(new Phrase("Text 2", Font)); cell1.HorizontalAlignment = 2; The reason? 回答1: You are confusing text mode with composite mode .
