I'll assume this is not a well known issue so some details may help. In particular, is color map shifted through entire image ( r->g for example) or does it change on each line?

I think now that you mention it I may have seen rendered pages from the open source viewer I used have color shifts (uniform color table change that looks like an off-by-one RGB alignment issue). I'm used to seeing this from various sources and wasn't important at the time so I didn't track it down.

[iText-questions] "Unknown Source" is such a bad thing?
After considerable effort, we narrowed down a symptom in a much larger system to this traceback: java.lang.NullPointerException at com.lowagie.text.pdf.SimpleBookmark.bookmarkDepth(Unknown Source) at com.lowagie.text.pdf.SimpleBookmark.getBookmark(Unknown Source) at com.lowagie.tools.concat_pdf.main(Unknown Source) from, in effect, an invocation of java -cp /usr/share/java/itext.jar com.lowagie.tools.concat_pdf L1.pdf O1.pdf This is 1.4.5 of iText. What are my prospects? L1.pdf is a 52-page instance that *looks* OK at a casual glance. It's probable that L1.pdf is the output from HTMLDOC operations. I suspect I can cut L1.pdf down more to probably just a few crucial pages that yield the NullPointerException. I'm open to advice, though: A. Is there any reason to think that someone else is already working on this fault? B. Is there any way I can pre-process L1.pdf or invoke iText differently so that the two get along better? C. Is there someone else who'd like to tackle this?

[iText-questions] Type3Font not displaying correctly with showtext()
I've been working on a simple test case to show "Hello World" on the pdf
document using a custom type3Font. I have defined my own type 3 font using
bitmaps and masked images. When I use Document.add(new Paragraph("Hello
World", Type3Font)), the text shows up just fine. The problem comes when
trying to use the showText("Hello World") when using the type3Font. All it
displays are dots with an error stating "cannot extract the embedded font

iText not support type3Fonts with the showText() method?

Re: [iText-questions] Extract jpeg image color problem
Image is CMYK in the PDF you aren't considering that. In addition, you are not
dealing with the Decode params nor the "Photoshop CMYK Inversion"
implementation note.

Thanks for the reply. The image is RGB (or that's what I think). I'm actually
using C# (itextsharp), but tried java with same result. Please have a look at
the test code snippet:
public void itext()
{
string pdfPath = "c:\\temp\\pdf\\1.pdf";
string outputPath = "c:\\temp\\pdf\\img.";
PdfReader pdfReader = new
PdfReader(pdfPath);
int size = pdfReader.XrefSize;
for (int i = 0; i < size; i++)
{
PdfObject obj =
pdfReader.GetPdfObject(i);
if (obj != null &&
obj.IsStream())
{
PdfDictionary pDic
= (PdfDictionary)obj;
if
(pDic.Contains(PdfName.SUBTYPE) && pDic.Get(PdfName.SUBTYPE).ToString() ==
"/Image")
{
string
filter = pDic.Get(PdfName.FILTER).ToString();
string
width = pDic.Get(PdfName.WIDTH).ToString();
string
height = pDic.Get(PdfName.HEIGHT).ToString();
string
bpp = pDic.Get(PdfName.BITSPERCOMPONENT).ToString();
// TODO

arr;
Bitmap
bmp;

(filter)
{
case "/FlateDecode":
arr =
PdfReader.FlateDecode(PdfReader.GetStreamBytesRaw((PRStream)obj), true);
using (bmp = new Bitmap(Int32.Parse(width),
Int32.Parse(height), PixelFormat.Format24bppRgb))
{
BitmapData bmd = bmp.LockBits(new Rectangle(0, 0,
Int32.Parse(width), Int32.Parse(height)),
ImageLockMode.WriteOnly,
PixelFormat.Format24bppRgb);
Marshal.Copy(arr, 0, bmd.Scan0, arr.Length);
bmp.UnlockBits(bmd);
bmp.Save(outputPath + "png", ImageFormat.Png);
}
break;
case "/DCTDecode":
arr = PdfReader.GetStreamBytesRaw((PRStream)obj);
using (MemoryStream ms = new MemoryStream(arr))
{
using (bmp = new Bitmap(ms))
{

Re: [iText-questions] "Unknown Source" is such a bad thing?
I suggest you try that tool commad with a more recent version of iText. 1.4.5 is a bit long in the tooth. --Mark Storer Senior Software Engineer Cardiff.com #include typedef std::Disclaimer DisCard; -Original Message- From: Cameron Laird [mailto:claird.visipr...@gmail.com] Sent: Wednesday, January 27, 2010 11:26 AM To: Post all your questions about iText here Subject: [iText-questions] "Unknown Source" is such a bad thing? After considerable effort, we narrowed down a symptom in a much larger system to this traceback: java.lang.NullPointerException at com.lowagie.text.pdf.SimpleBookmark.bookmarkDepth(Unknown Source) at com.lowagie.text.pdf.SimpleBookmark.getBookmark(Unknown Source) at com.lowagie.tools.concat_pdf.main(Unknown Source) from, in effect, an invocation of java -cp /usr/share/java/itext.jar com.lowagie.tools.concat_pdf L1.pdf O1.pdf This is 1.4.5 of iText.

I suspect I can cut L1.pdf down more to probably just a few crucial pages that yield the NullPointerException. I'm open to advice, though: A. Is there any reason to think that someone else is already working on this fault? B. Is there any way I can pre-process L1.pdf or invoke iText differently so that the two get along better? C.

[iText-questions] Possible bug in function ComputeOwnerKey (PdfEncryption.cs, PdfEncryption.java)
Hi,
I'm a developer from the PDFCreator team. We are using itext and I think I
found a bug in the function ComputeOwnerKey PdfEncryption.cs,
PdfEncryption.java).
I have created some files with Ghostscript and want to open them with itext.
But if I use encrypted pdfs (EncryptionRevision=3; KeyLength=40) itext can't
open these files and throws an exception "bad user password" though I didn't
set a user password. There is no problem if I use (EncryptionRevision=3;
KeyLength=128). Acrobat and other have no problems opening these files.
So I checked the source and I think I found a bug.
The pdf reference 1.6
(http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf)
said on page 101:
8. (Revision 3 or greater) Do the following 50 times: Take the output from
the previousMD5 hash and pass the first n bytes of the output as input into
a new MD5hash, where n is the number of bytes of the encryption key as
defined by the value of the encryption dictionary’s Length entry.
But in the source you can find these (PdfEncryption.cs):
private byte[] ComputeOwnerKey(byte[] userPad, byte[] ownerPad) {
for (int k = 0; k < 50; ++k)
Array.Copy(DigestComputeHash("MD5", digest), 0, digest, 0, mkey.Length);
First it computes the MD5 and then takes the n bytes and this is not
correct. There is no problem if you use a key length of 128bit. In this case
you use all bytes. But you'll get a problem if the keylength is not 128bit
for example 40bit.
I changed the line:
Array.Copy(DigestComputeHash("MD5", digest), 0, digest, 0, mkey.Length);
to
Array.Copy(DigestComputeHash("MD5", digest, 0, mkey.Length), digest, 16);
.
And now it works for 128bit and 40bit.
Can you check this please.
Best regards,
Frank
Team PDFCreator

Re: [iText-questions] Merge of detached signature
Hello Andreas, im on the same issue here.
When you talk about " store the half-baked pdf on the disk ".
Im trying to do that by making some serialization on the Stamper but nothing
is serializable in ITEXT.
So , im trying to do this way.
[CODE]
// write the current file.
byte[] buf = new byte[8192];
java.io.InputStream s = sap.getRangeStream();
ByteArrayOutputStream ss = new ByteArrayOutputStream();
int read = 0;
while ((read = s.read(buf, 0, buf.length)) > 0) {
ss.write(buf, 0, read);
}
// write SS to the disk.
FileOutputStream fos = new FileOutputStream("blank.in_process");
ss.writeTo(fos);
fos.close();
ss.close();
[/CODE]
But when im trying to read the stamper again to put the signature on :
PdfReader reader = new PdfReader("blank.in_process");
PdfStamper stamper = new PdfStamper(reader,new
FileOutputStream("signedDoc.pdf"));
PdfSignatureAppearance sa = stamper.getSignatureAppearance();
The signature PdfSignatureAppearance is null
I think im missing something here ...
How you procede to store the half-baked pdf on the disk ?
Did i procede the right way ?
Cheer's
Christian Leclerc
Couldn't remember that I ever disagreed with Leonard, but now it's the time
!
Of course it's possible what your describing :
- Build a semi-signed PDF with room for the signature
- Get the hash value
- Store the half-baked PDF on disk
- Sign the hash and create a PKCS7-Signature, somtimes later, somewhere
- Insert the signature into the spare bytes in the PDF
- Ready
Due to wierd legal requirements we had to take this multi-step approach and
it works !
Greetings
Andreas
