today, i'm working with iTextSharp and I'm trying to create a PDF document with a specific structure. For that, I need to insert "blocks" (like a div in HTML) in my PDF document. This blocks have to have a border.
At the moment, i'm using PdfPTable element but I would like know if another block type exists. In my blocks, I will insert Paragraph elements, Table elements, ...
Thanx for your help

Is there a solution to get inline elemnts in a custom content element? I only know thd solution to set the page with the data records in the content element where the inline elements are stored.
But i woult like to create a new content element and then put some inline elements directly in it.
Yes, you can add IRRE items on your content element. You need to create the relation between the content element and the table where the IRRE items are saved and get them via the DatabaseQueryProcessor.
Here you can get inspired on how you can achieve this:

I am stitching a couple of documents together with a requirement that each document should retain its header and footer information in the final document. Using AltChunk instead of raw OpenXml or DocumentBuilder saves a lot of effort with regards to styles, formatting, references, parts, etc.
Unfortunately, after a couple of days I can't seem to get a 100% working version due to a small and frustrating issue and I need some insight.
My code is loosly based on this article
I modify each sub document, prior to appending it (as an AltChunk) to a working document, by moving the last section properties into the last paragraph (in order to retain header and footer references), but Word seems to be adding a blank paragraph to each of these documents as it renders them in the final document. I end up with:
document 1 with correct header and footer
section properties/break
blank paragraph
document 2 with correct header and footer
section properties/break
blank paragraph
etc.
I cant remove the blank paragraphs afterwards, as I ideally don't want to use WAS to render the document first.
It seems as if you cannot have a next-page section break without a following paragraph?
After further investigation, it seems that will not be away around my usage scenario. I would need to place the last section properties in the body element, but due to my way of processing with nested AltChunk, it would not work.
I have changed my approach completely and went back to a more detailed append procedure using OpenXml Power Tools and some LINQ to Xml.
I'm using Document Builder and works perfectly for me!
var sources = new List<OpenXmlPowerTools.Source>();
sources.Add(new OpenXmlPowerTools.Source(new WmlDocument(#tempReportPart1)));
sources.Add(new OpenXmlPowerTools.Source(new WmlDocument(#tempReportPart2)));
var outputPath = #"C:\Users\xpto\Documents\TestFolder\myNewDocument.docx";
DocumentBuilder.BuildDocument(sources, outputPath);
I have the similar empty paragraph issue while importing HTML files.
My solution is,
After inserting HTML AltChunk, I add a GUID place holder. After processing the file, I will open the file again, locate the GUID and check if there is a empty paragraph before it, if so remove the empty paragraph and GUID. it seems work perfectly in my solution.
Hope it helps.
I am using iTextSharp to generate a PDF on the fly. I am using the ColumnText class in text mode using the ColumnText.SetColumns() method to define column boundaries using code like the following:
myColumnText.SetColumns(leftCoords, rightCoords)
myColumnText.AddText(New Chunk("Lorem ipsum..."))
myColumnText.AddText(Chunk.NEWLINE))
myColumnText.AddText(Chunk.NEWLINE))
myColumnText.AddText(New Chunk("Lorem ipsum..."))
myColumnText.AddText(Chunk.NEWLINE))
myColumnText.AddText(Chunk.NEWLINE))
As you can see, I emit a block of text and then two Chunk.NEWLINEs to add whitespace between paragraphs.
I then use ColumnText.Go to emit the content, creating new pages as needed, like so:
While ColumnText.HasMoreText(myColumnText.Go())
myDocument.NewPage()
myColumnText.SetColumns(leftCoords, rightCoords)
End While
The problem I am running into is that depending on the content in the ColumnText object a page break might occur right at the end of a chunk of text but before the Chunk.NEWLINEs, meaning that the content on the next page starts with two Chunk.NEWLINEs rather than at the top of the page.
Is there a way to somehow suppress Chunk.NEWLINEs if they are the first things emitted on a new page? My thought was that if I could somehow see the text that was about to be emitted by ColumnText.Go I could see if I was about to emit a Chunk.NEWLINE and remove it from the content stream or something...
Thanks
I've a template for word. In header and footer I've got logos of my company. The data of word is generating automatically from ERP program (that works great).
I only want to show some table with data on last page. I've tried this this method But it only works for text. When I'm updating the field the table and it's content disappear.
Anyone knows how to apply this method on table? It must to be automatic.
The same method works for block level content such as paragraphs or tables. Simply follow the same steps but instead of typing "Initials" insert your table there. Make sure to use speechmarks in the conditional e.g it should look like this { IF {PAGE} = {NUMPAGES} "" "(table)" }
I have written C# code to save product specifications to a PDF document using iTextSharp, mainly with PdfPTable and Chunks/Paragraphs in the PdfPCells. However, I have been told that the output is unacceptable due to the fact that you can highlight and copy the text from the document and document storage and retrieval server software that they are currently using does not support "Vector" based PDFs. I'm not exactly certain what the difference is between a raster pdf and and vector pdf. Basically, every page of the PDF Document should be an image so that the text can not be highlighted. Is there any way to do this without using the DirectContent? Below is an image, illustrating a portion of the PDF that was created, and how the text can be selected and copied, which is the incorrect functionality.
I would like to avoid directly writing to the canvas, unless there is a way to do this and still have itextsharp handle my formatting and proper paging.
The windows application PDF2R works well, but doesn't seem to offer any programmatic solutions. I have found libraries that stated that they do this sort of conversion, but are several thousand dollars. I'd like to work within my budget and use the itextsharp or something much cheaper than this.
I would suggest you try to generate an image using the System.Drawing class and then insert that into the PDF document.
Call this code on your PdfWriter object:
writer.SetEncryption(PdfWriter.STRENGTH40BITS, null, null, PdfWriter.AllowPrinting);
This won't prevent users from selecting text, but it will prevent them from copying and pasting it. Give it a try.
