itextsharp

问题 I'm using itextSharp to export a DataTable to a pdf table. I can export the data to a pdf table using the sample code i have posted below. The DataTable contains close to 21 columns. The first column in the pdf (DataTable) might contain similar values for any number of rows. If the data values in first column for a group of rows is similar, i want to merge the first 3 columns of those rows as one cell. I'm having trouble modifying the code below to achieve this. public iTextSharp.text.Table

问题 I need to extract PDF identifier mentioned in the trailer section of the document. But I am not able to get that value. Eg.

问题 Using c#, I want to see if a specific check box is checkd on a PDF page. The PDF file is not a form one. PDF could be something like: Sample file is here: MDS30ResidentP2.pdf (in this sample file, I want to somehow figure it out that check-box "E" in the question A1000 is checked.

问题 I am using iTextSharp to manipulate PDF documents. I have to make PDF document encrypted and I am able to do it. The only problem that I am getting now is the format of form fields - they got changed. For example: I have text field of ' Integer ' type with format ' 1,234.00 '. Before encrypting the format is what I have set. But after encrypting the PDF the format changes to default i.e. value becomes ' 1234 '. Any suggestion? UPDATE: I am using following code to set password on document:

问题 I'm using iTextSharp to handle pdf files. I'd like to know how I can split a page in half and make 2 different pages from the two pieces. I tried a lot but nothing seems to work right now. First try iTextSharp.text.Rectangle size = new iTextSharp.text.Rectangle(0, pdfReader.GetPageSize(1).Height / 2, pdfReader.GetPageSize(1).Width, 0); Second try iTextSharp.text.Rectangle size = pdfReader.GetPageSizeWithRotation(1); iTextSharp.text.Document document = new iTextSharp.text.Document(size
