问题 I'm trying to use iText PDFSweep RegexBasedCleanupStrategy to redact some words from pdf, however I only want to redact the word but not appear in other word, eg.

问题 I am reading specific location from an input pdf file with n number of pages and making a list of the texts on those locations. Then I write a new pdf document and write those strings from the list into a table with cells. I came up with two main problems. I want to have three columns in the table but if my strings in the list were not a multiple of 3 (i.e., the number of columns) then it would leave extra strings and would not print them. For example if I have 4 strings to print then the

问题 I'm beginning the process of updating code written against iText5 to work with iText7. Is there a similar mechanism in iText7 to the FontSelector class, where you would load up fonts and the "Process" action would automatically determine which font to use (and return a formatted pdf "chunk" that could be added to the document)? Here's the code snippet (this is C++, but my "native" language is C#, so feel free to answer with C#). try { doc = gcnew Document(); pdfWriter = PdfWriter::GetInstance

问题 I have been working with itextSharp-5.5.5, (5.5.10 / 5.5.13) Having issue with all version. TypeInfo typeInfo = typeof(PdfPKCS7).GetTypeInfo(); FieldInfo rsaDataField = typeInfo.GetDeclaredField("RSAdata"); Object rsadatafieldcontent = rsaDataField.GetValue(pkcs7); if (rsadatafieldcontent != null && ((byte[])rsadatafieldcontent).Length == 0) { _log.Info("Found zero-length encapsulated content: ignoring"); rsaDataField.SetValue(pkcs7, null); } if (pkcs7.Verifyc()) <------ **HERE return false**

问题 I am using iText library to create a pdf file from given string. But how can i save this document file to external storage ?

问题 I'm generating PDF documents using iText(Sharp). I'm developing the app using Visual Studio 2017. I've added iTestSharp using NuGet and I've experimented with both VB and C# All is fine for the 'high-level' stuff (chapter 1 from the jumpstart tutorial). Now I want to go more low-level using 'page', 'canvas' and 'low-level' drawing commands : chapter 2 from the jumpstart tutorial http://developers.itextpdf.com/content/itext-7-jump-start-tutorial/chapter-2-adding-low-level-content My problem is

问题 I have a piece of code that generates my PDF. I am trying to figure out how to add a footer to every page but I don't know how. I have seen a lot of examples in C# but I can't seem to find out how to exactly add the footer using VB.net (C# skills aren't that great). I believe that the correct way is to use the OnEndPage feature but I have no idea on how to add that in my code at this moment. I am new to this so any help would be great. The code below is what I am using now. Private Sub

问题 I use SAXItexthandler to achieve custom underlining of specified thickness, color & specified Y position using the below code. So basically i have different strings in multiple itext cells in a itext row and the below code helps me to do the underlining for every chunk where every chunk is embedded within a cell and it works perfectly fine. Color c = Color.decode(custom_color); currentChunk.setUnderline(c, thickness, 0.01f, ypos, 0.01f, PdfContentByte.LINE_CAP_BUTT); Now is there a way i can
