I made a Report containing rows and column. When Exported it to word document ([EXternal Dat tab->export section-> more->). All the text data exported except border lines of tabulated data.
Is there any solution to keep intect the borders of table in expored word/rtf document.
I have also tried "activedocument.tables. borders.enable = true " [earlier suggested][1] but no table object found in expored rtf word file. Images- output in pdf format and output in rtf .

I wanted to download an image from the web. But when I 'save image', it opens as a .txt file. I figure this is some type of encoding for the image but I can't find out which.
I want to eventually automate downloading the image for further processing, specifically text recognition. I've tried to convert the .txt using some online base64 encoders/decoders with no success. However, https://convertio.co/ was able to convert the .txt to .gif but I don't know how it did what it did.
I've given a sample of the .txt file. The actual file is much bigger.
The file name beings as such (if it helps):
data:image;base64,R0lGODlhyABGAIMAAPRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNvRDNv///ywAAAAAyABGAAAE+vDB (and it goes on, its very long).

I can see that there are '|' characters in between. May be for separating pixels.

It's seems to be a GIF image encoded as a data URL:
data:image;base64,R0lGODlhyABGAIMAAPRDNvRDNvRDNvR...
This format can be used in HTML and CSS file and is handy because the image data is directly embedded in the HTML/CSS file and does not need to be loaded with a separate request.
The start of the text basically says it's data URL, containing data for an image and the image is encoded using Base 64.
To decode it:
Chop off the start of the text, namely data:image;base64,.
Run the remaining text (R0lGODlhy...) through a Base64 decoder. The result will be binary data.
Save the binary data to a file using a file name with the extension .gif.
Now you have a proper GIF image as a file.
Our project has requirement to generate end report both in PDF and MS-Word Document. We are using iTextSharp to dynamically generate tables and rows in report. Finally we will upload the file to server as PDF and MS-word. Both will be converted to Byte Array/Stream file and saved as PDF and MS-Word Document. In Which,uploaded PDF working as expected, but MS-word getting error and not opening(Attaching the screen shot).
iTextSharp doesn't produce MS Word documents, so this isn't an actual iText question. When I look at your screen shot, I see that you are trying to import a PDF file into Word. Since Word can't interpret PDF syntax, it shows you the syntax of the PDF file:
%PDF-1.4
%âãÏÓ
1 0 obj
<</Type/Font...
I think your question is wrong. You are not using iTextSharp to create a PDF file and an MS Word file. You are using iTextSharp to create a PDF file, and not an MS Word file.
There is no such thing as "Save a PDF as MS Word file" in iTextSharp, and it will be extremely difficult to find another tool that can convert a PDF document to a Word document in an acceptable way. (There are such tools, but the quality is suboptimal for PDFs that weren't made to be converted to another format.)
I use pdftk for filling forms.
and now when I enter
F:\GoogleDisk\projects\comparepdfs>pdftk new/file.pdf
fill_form new/b2bf7150aa9de8b2ef8edd20a5677f7f.fdf output new/temp_b2bf7150aa9de8b2
ef8edd20a5677f7f.pdf
returned
Warning: input PDF is not an acroform, so its fields were not filled.
How fix it or convert PDF to acroform?
I decided it.
Combine files in Acrobat - and it create new pdf.
New pdf is good.
I am using iTextSharp to fill pre-defined fields on an existing PDF document using the folowing syntax:
PdfStamper stamper = new PdfStamper(reader, stream);
stamper.AcroFields.SetField("A","O'Henry");
stamper.FormFlattening = true;
stamper.Close();
Unfortunately, apostrophes (and likely other forms of common punctuation) are not displayed in the output PDF. For instance, in the code above, field "A" displays the text "OHENRY" instead of "O'HENRY".
How do I get the output PDF to display the text including the apostrophes?
Also, please note that I do not have control over creating/modifying the original PDF being filled. I was given the PDF from an external source and will likely be given new versions of the PDF as the form changes.
Thanks!
An easy fix is to replace the single quotes with the ` character.
I found a solution here http://www.nabble.com/Populating-form-fields-with-Unicode-data-td21610346.html.
This solution involves embedding into each field a font that can handle the desired characters.
