问题 I'd like to insert a PDF page in another PDF page scaled. I'd like to use iTextSharp for this. I have a vector drawing which can be exported as a single page PDF file.

问题 Summary: How can I reduce the amount of time it takes to convert tifs to pdfs using itextsharp ? Background: I'm converting some fairly large tif's to pdf using C# and itextsharp , and I am getting extremely bad performance. The tif files are approximately 50kb a piece, and some documents have up to 150 seperate tif files (each representing a page).

问题 I have a question about checkbox fields, and consistently figuring out which value to use for a checked state. I have been searching, and shelled out $50 for the iText in Action book and scoured it as well. The book is great, but it didn’t answer this particular question.

My question is: how do I definitively know WHICH of the

问题 How can i set an image to a pdf field in existing pdf file? I'm using the iTextSharp object. Setting the text field is working fine. No problem in it. pdfFormFields.SetField("Firstname", "Mujeeb"); Please help. 回答1: Remove the Text field and replace it with a Pushbutton field of the same size and position.

问题 I’m using Visual Developer 2010, MVC 3, c#.
