This is the code that I am using to insert the imagen in the PDF. This source
code works fine in others PDFs, but not in this one. I do not understand.
public TC2 InsertaImagenTC2(PdfReader reader, String ruta, int paginas) {
TC2 pdf = new TC2();
int i = 0;
PdfContentByte content = null;
if (paginas <= 0) {
System.out.println("Pagina 0 o menor");
return pdf;
}
try {
Image image = Image.getInstance("c:\\firma.jpg");
image.scaleAbsolute(180, 100);
image.setAbsolutePosition(360f, 20f);
PdfStamper stamp = new PdfStamper(reader, new
FileOutputStream(ruta.replace(".pdf", "temp.pdf")));
for (i = 1; i <= paginas; i++) {
content = stamp.getUnderContent(i);
content.addImage(image);
}
stamp.close();
} catch (Exception e) {
e.printStackTrace();
}
pdf.setRuta(ruta.replace(".pdf", "temp.pdf"));
pdf.setTotalpaginas(i);
pdf.setDesde(1);
pdf.setHasta(i);
return pdf;
}
I have tried to do a indirect reference, but I need a PdfObject. I do not know
how to create a PdfObject without using the inheritance.
someOtherDict.put( PdfName.ANOTHER_KEY, myWriter.addToBody( myDict ) ); //
put(PdfName key, PdfObject object)
Regarding to the fail of the ContentStream, it is imposible to solve it because
the generated PDF by Crystal Reports is a mess. I tried to fix it with
PdfContentReaderTool, but it shows a lot of information that I do not
understand.
If I could insert the imagen with the PDF generated by the PDF printer. I would
solved the problem.
Thank you.

Subject: Re: [iText-questions] Reading text from PDF
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?

[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

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
