Heh heh :-) I found this in PDXObjectImage.java:
{code}
// assume default values ([0,1]) for the DecodeArray
// TODO DecodeArray == [1,0]
graphics.setComposite(AlphaComposite.DstIn);
{code}
I tried to replace that with the following lines and it works, but I'd like to
hear another opinion because my day job doesn't involve [Porter/Duff
rules|http://ssp.impulsetrain.com/porterduff.html]:
{code}
COSArray decode = getDecode();
if (decode != null && decode.getInt(0) == 1)

The problem is that as long as you insist on using 1.4 we won't know whether
the problem is related to that or to another cause.
Enter java -version to find out what's really running.
Btw it could still be a corrupt file even if you can open it with Adobe, so
please try with different files.
There's also jstack in the jdk bin directory, Google for it on how to get a
thread dump.

[jira] [Commented] (PDFBOX-1994) PDDocument.load(filename.pdf) hangs for pdf files having size

Andreas Lehmkühler commented on PDFBOX-1994:
- the stack trace is explicit, at least one class is missing. You somehow mixed
your environment. This has nothing to do with PDFBox.
- as Tilman already mentioned PDFBox 1.8.x requires Java 1.5. So either your
are not using PDFBox 1.8.x or your are not using a Java 1.4 environment.
- you should asked someone familiar with Launch4J how to configure it correct
to get a working executeable or the even better idea you should think about
using the JDK directly without a jar->exe converter.

yes, add println statements in between . that is why i understand it hangs on
the single line.

Could you add a writeln before and after each pdfbox related call so that you
can tell which one hangs?

If you are using a UNIX style server system run a
kill -3 PROCESS_PID(or -QUIT)
on the server Java process.
This will give you a stack trace of the Java VM at stdout/stderr(?) - may this
is redirected to a log file in your case. So you will see where it hangs. If it
hangs in PDFBox you can provide us with this stack trace.

hi ,
tested with PDDocument doc = PDDocument.loadNonSeq(file , null);
But the same issue , it hangs.
1- tested the pdf file size (it is not zero size)
2- added all permissions to the specified folder / files
3-it is not a corrupt file also.
still i didnt understand where is the exact issue.

Btw the 2nd param of loadnonseq can be null.
It is important to get rid of external factors like that exe packer and then
approach the real problem step by step. Currently your main class cannot be
found.

Looks like you are missing a number of libraries in your jar test case but all
of them do not belong to PDFBox.
It seems to me that in general this is no PDFBox issue but an issue of your
server environment. I would propose adding more test code in your server
version (test first if file is readable etc.; after loading do some logging
before trying to print document, ...) and use PDDocument.loadNonSeq instead of
PDDocument.load.

Hi,
while testing the .jar , getting exception,

Could not find the main class: specgas.MainGas. Program will exit.
---So i cant test the .jar.
- But i am confidant that , this is working fine in local with java 1.4 version.
and other code and corresponding .jar is working fine in server , except
'PDDocument.load' statement.
control is hanging with no error message.
- Can u please provide me any other method for converting the .jar to .exe ?

Re: [GSoC 2014]Optical Character Recognition project - Introduction
Hi John, I looked at processTextPosition method in PDFTextStripper. But I couldn't understand actual process happening inside the method. What should be the input for that method? In my case I have words with bounding box's coordinates. How can I make those data to compatible with the input of processTextPosition method. As well, what is the output of the method?
