Itext Problem

sorry to take so long, been a bit busy.

the "|" char is java syntax for bit ORed. so to cobble together different
permissions that you want to negate you might do something like:

pdfPermissions=bitOr(pdfCopy.ALLOWPRINTING,pdfCopy.ALLOWCOPY);
// don't allow any of the pdfPermissions
pdfCopy.setEncryption(pdfCopy.STRENGTH128BITS,"",passwd,bitNot(pdfPermissions));

if there's more than two permissions you need then maybe:

pdfPermissions=bitOr(pdfPermissions,pdfCopy.ALLOWMODIFYCONTENTS);
pdfPermissions=bitOr(pdfPermissions,pdfCopy.ALLOWASSEMBLY);
.
.
.
etc.

I use Coldfusion 7.0.2 with the itext that came with it.
My code (99% based on yours :-) :

if (i EQ 1) {
pdfDocument.init(reader.getPageSizeWithRotation(1));
pdfCopy.init(pdfDocument, newPDF);
// make sure we turn off printing or modifying or ... BEFORE we open the new PDF
passwd = createuuid() ;
pdfCopy.setEncryption( pdfCopy.STRENGTH128BITS, "", passwd, bitNot(pdfCopy.AllowModifyContents)
);

pdfDocument.open();
} // first file in list?

If I replace "bitNot(pdfCopy.AllowModifyContents)" by "pdfCopy.AllowScreenReaders | pdfCopy.AllowCopy | pdfCopy.AllowPrinting". I have the following error : "Invalid token '|' found on line 310 at column 100."

what ver of iText? show your code.

ok it works for me, but just for one parameter a the same tilme.
pdfCopy.setEncryption(pdfCopy.STRENGTH128BITS,"","123456789",bitNot(pdfCopy.AllowModifyContents));

if I repeat this line with different attributes (AllowPrinting...) it's not working

The docs said that it's possible to concatenate multpiles "AllowXXX" using | (pipe) but it does not work !

I want to do the following thing :
no password for reading
a password for editing
without password, you can read & print the PDF, but nothing else (not removing a page, not edit text, ...)

How can I do ?

Has anyone got into a problem generating very large pdf files. Our process kills the jrun once the pdf file generated is larger than 14mb?

Thanks

Thanks Paul....

post enough of your code to see what's going on.

I get the following error

The selected method setEncryption was not found

I'm using a itext 1.4.6.

AllowPrinting is a user permission *field* in PdfWriter. if you have initialized
a PdfWriter class then you can do PdfWriterObjectName.ALLOWPRINTING or simply
javacast on it's value, 2052.

newPDF=pdfStamper.setEncryption('','',javaCast("int",2052),0);

if i can offer some advice, grab a copy of bruno's book if you plan on doing
much w/Itext. very good value.

Hi Paul

I've come up with the following
newPDF=createObject("java","java.io.FileOutputStream").init(expandPath(finalOutPutFile));
pdfStamper=createObject("java","com.lowagie.textNew.pdf.PdfStamper");
newPDF=pdfStamper.setEncryption('','',AllowPrinting,0);

Is that even close? Currently, I get an AllowPrinting is undefined error.

The notes suggest that the command should accept an int and yet the options inlude allowprinting etc..
