In case the Tiff was recorded as a received fax image - the reason could

I am getting the exception while reading a tiff using the
TiffImage.getTiffImage method (in code below). If I step through the code in
the debugger (netbeans) I cannot duplicate the failure.

Is this a timing issue? Should I slow the execution down?

I've given a look at what happened inside Itext and i found that the 
instruction that launch exception is:
"System.arraycopy(key, 0, mkey, 0, mkey.length);"
where key is a 20 bytes arrays and mkey.length is 32!

With the other algorithm (ARC4_40, ARC4_128, AES_128) i have no problem!

I attach the pdf that i want to encipher.

I thank you in advance

[iText-questions] ArrayIndexOutOfBoundsException

2010-09-14 Thread Samy 

Hi,

I am using the iText 1.3 jar file to run a Java Agent on Lotus Notes, which
does merge the PDFs.
I have been facing an issue for a while now when I select two or three
documents (which are PDFs) and click on MergeDoc, I get this series of
errors. 

This nature of throwing errors does not happen in a pattern, very sporadic.
9 out 10 times it works fine.



Please take a look at the stacktrace below:

Here is the code I use to merge documents:

AgentContext agentContext = session.getAgentContext();

// getting the configuration profile
Database db = agentContext.getCurrentDatabase();
View confView = db.getView("Configuration");


Document confDoc = confView.getFirstDocument();
DocumentCollection dc = 
agentContext.getUnprocessedDocuments();
Document doc = dc.getFirstDocument();

// final merged pdf file
PdfCopyFields copy = new PdfCopyFields(new
FileOutputStream(confDoc.getItemValueString("temp")+ "MergedDoc.pdf"));

//looping through documents
while (doc != null) {

RichTextItem rtitem = (RichTextItem) 
doc.getFirstItem("Body");

if (rtitem != null) {
EmbeddedObject obj = (EmbeddedObject)
rtitem.getEmbeddedObjects().elementAt(0);

if (obj.getType() ==

// this is to check whether the

// extracting the

No, IMO it should just use the bytes given, not more, not less.

If you look at the PDF document using a text or hex viewer or a dedicated
PDF analysis tool, you'll find the trailer dictionary nearly at the end of
it. In the case of your example document 
http://old.nabble.com/file/p28472754/74AA0C69-01F4-4114-6A2D-81D7E7101480-0-IDS-1-BLP.PDF
74AA0C69-01F4-4114-6A2D-81D7E7101480-0-IDS-1-BLP.PDF :

trailer
<>

The document ID is the entryin square brackets after the /ID name, i.e. (22)
(22). This is wrong. The PDF spec ISO 32000-1:2008 states in 14.4:


File identifiers shall be defined by the optional ID entry in a PDF file's
trailer dictionary (see 7.5.5, "File Trailer"). The ID entry is optional but
should be used. The value of this entry shall be an array of two byte
strings. The first byte string shall be a permanent identifier based on the
contents of the file at the time it was originally created and shall not
change when the file is incrementally updated. The second byte string shall
be a changing identifier based on the file's contents at the time it was
last updated. When a file is first written, both identifiers shall be set to
the same value. If both identifiers match when a file reference is resolved,
it is very likely that the correct and unchanged file has been found. If
only the first identifier matches, a different version of the correct file
has been found.

To help ensure the uniqueness of file identifiers, they should be computed
by means of a message digest algorithm such as MD5 (described in Internet
RFC 1321, The MD5 Message-Digest Algorithm.


At first glance, that ID of yours is wrong as it uses literal strings and
not byte strings. It additionally is likely wrong as a two-character ID
generally does not ensure uniqueness.

On the other hand iText is wrong in assuming a length of exactly 16 bytes in
PdfEncryption.createInfoId() because the MD5 digest is merely an example for
a way to generate something unique enough.

Regards,   Michael.

Thanks, Michael - that is exactly what I needed to know!  I will take this
issue up with Oracle.

I will also see if I can find some work-around to make the file acceptable
to iText.  Maybe I can edit the ID or re-save the file before trying to sign
it, forcing the generation of a new ID?

Re: [iText-questions] ArrayIndexOutOfBoundsException when signing Documaker PDF

2010-05-06 Thread msinatl 

Michael,

Thanks for your response. Please pardon my ignorance, but what is the
document ID and how can I retrieve it?

It seems that PdfEncryption.java has a createDocumentId() method that builds
the document ID from some semi-random elements:

public static byte[] createDocumentId() {
MessageDigest md5;
try {
md5 = MessageDigest.getInstance("MD5");
} catch (Exception e) {
throw new ExceptionConverter(e);
}
long time = System.currentTimeMillis();
long mem = Runtime.getRuntime().freeMemory();
String s = time + "+" + mem + "+" + (seq++);
return md5.digest(s.getBytes());
}

Anyway, here is an example file, generated by Documaker, that I am working
with.

At PdfEncryption.java:401 iText creates the literal representation of a
document ID from a byte[] representation. iText stumbles as the byte[]
parameter is merely 2 bytes long, not 16 as expected. You might want to look
at the ID in your source document.

(Ok, the code of createInfoId might be made more fool-proof by checking the
byte[] parameter, but for valid PDFs the assumptions implicitely made here
are correct.)

If that ID looks ok in your document, please forward that document (or any
other one making that issue reproducible) for inspection.

Regards,   Michael.

[iText-questions] ArrayIndexOutOfBoundsException when signing Documaker PDF

2010-05-05 Thread MSilverboard 
Hi, 

I've got a problem using iText to digitally sign a PDF.  The Groovy script 
below works fine with a test PDF I created in Acrobat Pro 7.0.  But when I 
run it on a PDF produced by my production document system (Oracle 
Documaker), I get this exception: 

java.lang.ArrayIndexOutOfBoundsException: 2 
at 
com.itextpdf.text.pdf.PdfEncryption.createInfoId(PdfEncryption.java:401) 

I'm using iText 5.0.2, JDK 1.6, and Groovy 1.5.6. 

Both PDFs are encrypted before my script begins - with printing and 
signing allowed, but changing of the document prohibited.  The Acrobat 7 
PDF is PDF Version 1.6; the Documaker PDF is PDF Version 1.4.  Both are 
encrypted with 128-bit RC4.  I don't know where to look for any other 
material differences between the two files. 

Does anyone have any thoughts on why iText throws an exception when trying 
to sign the Documaker-generated PDFs?

Your jpeg is broken in the icc profile segment count. I'll add something in 
the code to take care of this.

This jpeg displays correct in a browser.
other jpeg files are working fine.
Is this a program error or is there something wrong with the jpeg.

The culprit is the convertWidth function which formats the floating values to

My solution:
Change the line

or
change

Thanks,
I did a RefactorIt Audit once and the problem you are describing is 
called a 'Dangerous Comparison'. RefactorIt recommends to solve it like 
this:
if(Math.abs(convertWidth(wb) - convertWidth(wt)) < 0.0001) break;
0.0001 is a precision you can chose yourself.
I have changed this one case, but I am aware of the fact that I should 
follow the RefactorIt suggestions in a lot of other cases too. 
Unfortunately the number of suggestions bu RefactorIt is so 
overwhelming, that I don't know where to start...

[iText-questions] ArrayIndexOutOfBoundsException resulting from Table.mergeInsertedTables()

2005-05-10 Thread Peter Hodgkinson 
I've noted that this problem has been discussed in a few threads around here,
and I've spend the past day and a half trying to debug it. Here's the problem /
solution I found.

The problem:
the following block in mergeInsertedTables

 while( ct=convertWidth(wb)) break;

or

change
private static DecimalFormat widthFormat = new DecimalFormat( "0.00");
to
private static DecimalFormat widthFormat = new DecimalFormat( "0.0");

[iText-questions] ArrayIndexOutOfBoundsException

2004-07-17 Thread Victor . Ayzenshtat 

Hi, i'm trying to run your sample code to create nested tables within a PDF document and i get :

java.lang.ArrayIndexOutOfBoundsException: 3
        at com.lowagie.text.Table.mergeInsertedTables(Unknown Source)
        at com.lowagie.text.Table.complete(Unknown Source)
        at com.lowagie.text.Table.insertTable(Unknown Source)
        at com.lowagie.text.Table.addCell(Unknown Source)
        at com.lowagie.text.Table.addCell(Unknown Source)


when the red line (aTable.addCell(tableCell, new Point(1,1));) in the code below executes.  This is the sample code from iText tutorial site.  I tried to create my own nested tables and my code also always fails on that same line.  Why does that happen?  Any help would be appreciated!  I use JDK 1.4x

thanks in advance,
-regards, 

Victor

Hi Paulo,

Thanks for your help.  I converted the JPEG to a PNG and got a better

enough.

Very, very bad choice. The compression artifacts will show up if you try to

This is integer calculation. The bits are packed but a line is padded to
fill the last byte. No byte spans two lines.

You'll need (135+7)/8 * 50 = 850 bytes.

Re: [iText-questions] ArrayIndexOutOfBoundsException when masking an image

2003-07-29 Thread Chris . Rauschuber 

Hi Paulo,

Thanks for the quick response.
The original image is a JPEG.

Why is that formula used?  On the tutorial, an 8 X 8 mask uses 8 bytes, but
would be 15 bytes using the formula below.

So, assuming that I need 888 bytes for a mask with 6750 pixels, how are the
byte values computed?

Thanks for your help,
Chris

The number of bytes must be:

(width+7)/8 * height

What is your original image format before the PlanarImage?

[iText-questions] ArrayIndexOutOfBoundsException when masking an image

2003-07-29 Thread Chris . Rauschuber 
Hello,

I have an image of a signature with height=50 and width=135 that I would
like to insert into a PDF.  I would like to mask it with the signature
itself so that the white background of the image is gone and only the
signature remains.  I've tried using the code below to do this, but I get
the following exception.  Am I constructing the mask correctly?  I assumed
that the number of bytes in the mask should be equal to the ceiling of the
number of pixels divided by 8(844 in this case).  Is this correct?

java.lang.ArrayIndexOutOfBoundsException: 844
at com.lowagie.text.pdf.CCITTG4Encoder.nextState(Unknown Source)

at com.lowagie.text.pdf.CCITTG4Encoder.compress(Unknown Source)
at com.lowagie.text.Image.getInstance(Unknown Source)
at com.lowagie.text.Image.getInstance(Unknown Source)


Here is the code:
 
 PlanarImage planarImage = getPlanarImage(value);
 byte[] mask = createMask(planarImage);
 Image maskImage =
Image.getInstance(
   planarImage.getData().getWidth(),
   planarImage.getData().getHeight(),
   1,
   1,
   mask);

 maskImage.makeMask();
 maskImage.setInvertMask(true);

 image.setAbsolutePosition(pageTokenDefinition.getX(),
pageTokenDefinition.getY());
 image.setImageMask(maskImage);
 pdfTemplate.addImage(image);
 

   private static byte[] createMask(PlanarImage image) {
  double[][] pixels = imageToBandArray(image, 0);
  int width = pixels[0].length;
  int height = pixels.length;
  byte[] mask = new byte[(int)Math.ceil(width * height / 8.0)];
  int maskIndex = 0;
  for (int pixelIndex = 0; pixelIndex < width * height; pixelIndex++) {
 if (pixels[pixelIndex / width][pixelIndex % width] == 0) {
mask[(int)Math.floor(pixelIndex / 8.0)] |= (1 << (7 -
pixelIndex % 8));
 }
  }
  return mask;
   }

   public static double[][] imageToBandArray(PlanarImage image, int band) {
  Raster raster = image.getData();
  int width = raster.getWidth();
  int height = raster.getHeight();
  int bands = raster.getNumBands();
  double[][] bandArray = new double[height][width];
  for (int n = 0; n < height; n++) {
 raster.getSamples(0, n, width, 1, band, bandArray[n]);
  }
  return bandArray;
   }

Re: [iText-questions] ArrayIndexOutOfBoundsException

2002-05-14 Thread Ben Sinclair 

I just tried something new that might shed some light on my problem.

This is what I have been doing:

Create a temp pdf and a real pdf. Write to the temp pdf, close it, then import
it into the real pdf.

Some of these variables are defined outside this method.

When I run this, I get the ArrayIndexOutOfBoundsException.

 tempPdf.close();

 System.out.println("tempPdf length: " + new File("rendertemp.pdf").length());
 try {

  PdfReader reader = new PdfReader("rendertemp.pdf");
  System.out.println("Number of pages: " + reader.getNumberOfPages());

  for (int i = 1; i <= reader.getNumberOfPages(); i++) {
   System.out.println("Adding page " + i);
   PdfImportedPage page = writer.getImportedPage(reader, i);
   PdfContentByte cb = writer.getDirectContent();
   cb.addTemplate(page,0,0); // Add temp pdf to the real pdf
try {
pdf.newPage();
   } catch (Exception e) {
System.err.println("Error starting new page");
   }
  }

 } catch (IOException e) {
  System.err.println("Couldn't open rendertemp.pdf!");
 }



Just for fun I tried to open an existing pdf that I didn't generate myself,
instead of rendertemp.pdf. That worked fine. I then renamed the temp pdf and
tried to append it, and that worked as well. It seems like if I generate my
temp pdf, close it, then import it into my real pdf right away, it doesn't
work.

Is there something more I have to do other than tempPdf.close() before I try
and open it?

I have a hacked version of Xpdf that will do this - report 
all sorts of problems with PDF's that you feed it.  However, you 
should also know that there are PDF's that Xpdf will report as 
"undamaged" that iText can't (currently) handle due to the way the 
PdfReader is structured.

A pdf validator is a most wanted tool but up to now the only way is to
import the pdf into acrobat or gs and see what happens. If the pdf opens ok
in these two readers it may be a problem with iText. In that case send me
the pdf for examination.

Probably the imported pdf is defective or there's some file access error.
This error only depends on the imported pdf.
