How to disable save Icon?

Question

We have a legal requirement in our bank that in our intranet site whatever document we show it should have save icon disabled? [thought there are lot if ways we can capture the contents of it even with save icon disabled]
Is there any way of implementing the save icon disabled...I spent almost three hours with no result.... My coding will look like this
int permissions = ~(PdfWriter.AllowPrinting | PdfWriter.AllowCopy | PdfWriter.AllowModifyAnnotations | PdfWriter.AllowFillIn | PdfWriter.AllowAssembly | PdfWriter.AllowModifyContents | PdfWriter.AllowScreenReaders);
PdfEncryptor.encrypt(reader,fos,true,"","",permissions);

Answer 1

I have pasted my code below
We are creating a new pdf and applying permissions for that....
I searched for more than two hours and couldn't find a way to disable save icon in the API we use
com.lowagie.text.pdf.PdfEncryptor;
com.lowagie.text.pdf.PdfReader;
com.lowagie.text.pdf.PdfWriter; [you can paste this in google which will explain this API]
I thought this as a constraint with this API, hence searching for other API's which has this feature...in most of the forums I saw implementing this as not possible....hence thought of checking in Adobe forum where people might suggest some other API...Please let me know whether this feature [if it is really a programmable feature] is available in API's you have used...Thanks Aandi Inston!
byte[] documentBytes = document.getContentBytes(); //which will get the content of a pdf
File newFile = File.createTempFile("tempPdfFile", ".tmp");
FileOutputStream fos = new FileOutputStream(newFile);
reader = new PdfReader(documentBytes);
int permissions = ~(PdfWriter.AllowPrinting | PdfWriter.AllowCopy | PdfWriter.AllowModifyAnnotations | PdfWriter.AllowFillIn | PdfWriter.AllowAssembly | PdfWriter.AllowModifyContents | PdfWriter.AllowScreenReaders);
PdfEncryptor.encrypt(reader,fos,true,"","",permissions);
