Re: How do I analyze a problem PDF?

[Thad Humphries]

No, the document has not been closed prematurely. It's being processed
through the same calls that I use for all my other documents that must
merge a PDF, either ones I create or ones from a repository. In this code

...
File outpath = new File(OUT_DIR, "mergedTwoPdfs.pdf");
document.save(new FileOutputStream(outpath.toString()));
...

when I trace the execution in Eclipse, document's close member is false
immediately before calling document.save().

Something else interesting: When I use PDFMerge to merge the good, 40K PDF
with another document, the output PDF is only 2K larger than the two files
themselves. But when I merge the original 39K PDF, the output is almost 40K
larger than the two files.

The code below will cause the error. The two portions in curly brackets are
(essentially) the merge method in my PrintToPdf class. The stack trace is
the same. The odd PDF is the second one, "moroccan_chicken.pdf".

I can see about a place to post it tomorrow, through a short-term anonymous
FTP at my office. In the meanwhile I'll see if anything from PDFDebugger
makes sense to me. :)


  @Test
  public void testMerge2PdfDocs() throws Exception {
File file0 = new File(this.getClass().getResource("/Bacon and Brussels
Sprout Hash.pdf").toURI());
byte [] buf0 = IOUtils.toByteArray(new FileInputStream(file0));
File file1 = new
File(this.getClass().getResource("/moroccan_chicken.pdf").toURI());
byte [] buf1 = IOUtils.toByteArray(new FileInputStream(file1));
PDDocument document = new PDDocument();
{
  PDFMergerUtility merger = new PDFMergerUtility();
  PDDocument inDoc = PDDocument.load(buf0);
  merger.appendDocument(document, inDoc);
  inDoc.close();
}
{
  PDFMergerUtility merger = new PDFMergerUtility();
  PDDocument inDoc = PDDocument.load(buf1);
  merger.appendDocument(document, inDoc);
  inDoc.close();
}
File outpath = new File(OUT_DIR, "mergedTwoPdfs.pdf");
document.save(new FileOutputStream(outpath.toString()));
document.close();
assert true;
  }

Re: How do I analyze a problem PDF?

[Tilman Hausherr]

The best would be to upload the PDF somewhere, and also post your code.

I analyse PDFs sometimes with NOTEPAD++, sometimes with PDFDebugger, and 
often both. But these help only those who know what to expect.


The text below looks like a COSStream was closed prematurely (did you 
close the source documents too early?). I'd rather suspect a bug in your 
code or in our code.

How do I analyze a problem PDF?

[Thad Humphries]

I have a PDF 1.4 document that opens in different PDF viewers without
warnings, yet there seems to be something odd about it. How might I analyze
it?

If I merge this PDF from the command line with pdfbox-app-2.0.4.jar's
PDFMerger, the output is fine. However anytime I merge it in my own code,
where it is first opened into a byte array, loaded to a document, then call
PDFMergerUtility's appendDocument(destination, source), the
destination PDDocument cannot be saved to disk. This is the only PDF of
several dozen I've tested with this problem. I see nothing odd when I trace
the program in a debugger. It fails only at PDDocument save() (stack trace
below).

If I open the original PDF (39K) in MacOSX Yosemite's Preview and save it,
the saved PDF is now 40K, and it merges just fine in my code. (I believe
this PDF was created about 5 years ago, most likely with the export-to-PDF
action using OpenOffice on Linux. )

I expect that I'll see odd PDFs like this from time to time. (Lord knows
that I've amassed quite a collection of buggy TIFF images over the years.)
With TIFFs I can find out a lot using libtiff's tiffinfo and tiffdump
utilities and a hex editor. Are there any routines in PDFBox that might
help me with PDF files? Are there any other tools, open source or
commercial?

Hi,
I verified the pom and it ended up being a silly thing:

I get what it is supposed...

It was my fault. I just copied the dependencies from

forgot to remove the scope. I am sorry. Thank you all for your help.

That's a nice link.

There is no reason to panic. The apache license is a very friendly 
license. You don't pay anything, and you're not required to publish your 
sources, but you must attribute the work you are using - which any nice 
person would do anyway.

I have written a program that uses pdfbox.

What do I have to do with it so that I legally conform to the apache 2.0

Sorry to bother you with such a naive question its just that legal stuff
always makes me panic.


Read it here:
https://www.apache.org/licenses/LICENSE-2.0
https://en.wikipedia.org/wiki/Apache_License
IMHO it is pretty clear what you have to do. However if reading that makes
you panic, you'll have to hire an attorney :-(

Hi Tilman,

this is what I get:

[JPG, jpg, bmp, BMP, gif, GIF, WBMP, png, PNG, wbmp, jpeg, JPEG]


Then it's really not there... JBIG2 is also missing. I'd suspect some 
problem with your build... try

- do a clean build
- verify that your pom is ok re: syntax
- run the tool both in and outside of your IDE
- have a look what is in your manifest / in your class path, i.e. what 
is really there? Look in the directories. You can look at jar files with 
any zip tool, e.g. 7zip.

- post the fill pom file.

I took the dependencies I put in the pom I showed in my mail.

I am getting the error even when the suggested dependencies are set.


It's very weird, I use the same dependencies and it works.

Please include

|System.out.println(Arrays.toString(ImageIO.getReaderFormatNa‌​mes()));|

in your code at the start, what do you get?
