Hi,
Doesn't anybody know how to do this, or am I asking some obvious question
that's been asked before.. sorry if that's the case.
I'm trying to find out a way to add some javascript to an existing pdf file
that will open up an alert as well as open up a url in the users browser when
the pdf file is closed.
I have managed to add javascript code using the pdfstamper that opens up an
alert when the file loads. Could someone please send me a code snippet that can
do the same when the file is closed.
Here is my code using stamper to show a javascript alert when the file is
opened.
Dim p As New PdfReader("c:\a.pdf")
Dim s As New PdfStamper(p, New FileStream("c:\b.pdf", FileMode.Create))
s.JavaScript = "app.alert(""Javascript Alert!"");"
s.Close()
I tried extending the PdfPageEventHelper but the onOpenDocument method
uses the pdfwriter and document as arguments, so if I use the writer then
it assumes that its a new document, where as I need the code added to an
existing file.
Thanks

Save it with JAI as a jpeg and use that jpeg in iText.

Hi,
I am using itext to create dynamic web pdf.
For some reason when i add the
Image jpg = Image.getInstance("image.gif");
I get a ExceptionConverter: java.io.IOException: The document has no pages
error.
This works when i save it on a pdf locally, but it doesnt work when I try to do
it dynamically on a web, using bytearrayoutputstream.

It's probably throwing an exception that you are ignoring.

Subject: [iText-questions] How to add Arabic text to a PDF
To: [email protected]
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=us-ascii
How can i add Arabic text to a PDF and have it displayed in the PDF ?.
Currently i am using the following code however, this does not display the
Arabic characters:
BaseFont bf = BaseFont.createFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252,
BaseFont.EMBEDDED);
column.addText(new Phrase(LINE_LEADING, arabicTitleStr , new
Font(bf,FONTSIZE_3)));
column.go();
Can anyone say what else will i need to do for this code to work? I am
following the example from the online Tutorial RightToLeft.java and
SayPeace.java.

Thanks for the response but i found that the problem is the location of the
image.
For some reason is not reading the image when i put the image inside the
workspace(where i have all the source code), but it reads it if i put it
outside of the workspace..
sincerely
geronimo.

Bruno has a great example of this in his SayPeace example in chapter 9
of his book.
Arabic glyphs are written as double byte chars.
Your encoding should be BaseFont.IDENTITY_H, and you should be using a
unicode font.
