First of all, I tried to run Acrobat 9.4 pro's PDF Syntax Check on
1.pdf: It FAILED! The error message stated that you had an illegal
content stream. I looked through the content stream and found the
following:
1) Everything is in picas (1/20 of a point), so some of the coordinates
are Quite Large... though none are so large that they should cause a
problem (> 0xFFFF). The original coordinate system crystal reports used
was "y increases from bottom to top", whereas PDF uses "top to bottom".
None of this is all that unusal.
2) The fonts are all custom-encoded subsets without legal subset names.
"Arial+0" and "Arial-Bold+1" instead of the usual "FontName+<six UPPER
CASE characters>" that is the Declared Standard way of doing things.
Again, not a huge deal, but not great.
3) One of the fonts is named "9". I don't think that's a legal resource
name... /9 is a perfectly valid PdfName... I don't see anything about
restricting font names to "valid variable names" as you'd see in C-esque
languages. A bug in the PDF validator perhaps? The PDF renders fine.
The first exception is a failure to read an array in a content stream.
That only happens within "kerned" text (google "kerning" if you'd like
to know more). Between the odd encoding and the kerning, it sounds like
CrystalReports created an illegal content stream. This may well be
what's choking the Pdf Validator.
In the case of the second exception, you're adding something as a direct
object when it should be added as a reference. For Example:
PdfDictionary myDict = new PdfDictionary();
someOtherDict.put( PdfName.SOME_KEY, myDict ); // added directly
someOtherDict.put( PdfName.ANOTHER_KEY, myWriter.addToBody( myDict ) );
// added as a reference
Only PdfWriter.addToBody() returns a PdfIndirectReference, not a
PRIndirectReference... Same concept, but your code will be different.
That's why we need to see it. Could you please post your code to the
list?

Subject: Re: [iText-questions] Reading text from PDF
I tired to solve this problem for myself during a month but I
could not.
The PDF that I have the problem with is called 1.pdf. I hope
that you can solve it.
What I pretend is to read the text of the PDF or directly remove
the regionClip that i think is giving me the problem.
This is the error:
java.lang.NullPointerException

com.itextpdf.text.pdf.PdfContentParser.readArray(PdfContentParser.java:1

I tried skip the error before by generating the PDF in a pdf
print. This works but later i find a diferent error. This error
is caused when i try to close the file after inserting a
picture. "stamper.close();". The PDF that i have the problem with is
called 2.pdf
java.lang.ClassCastException:

From the beginning my intention has been read the PDF and to
insert it a picture that i want.
Thank you.
