Tilman Hausherr commented on PDFBOX-4750:
-
Test was also to see whether we increased code coverage. Sadly it dropped from
46% to 45.6% (maybe because of other commits that balanced things differently).
The code coverage of the class went up to 79.6% from 43.4%.
TODOs:
- use only page 8
- same test for 2.0
- loading of file through pom
- find whether file that has dictionary (isn't covered)
- correct formatting for dictionary (probably unneeded space)

Snapshot available at
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/2.0.19-SNAPSHOT/
I also did a test on the attached file, with this code:
{code}
try (PDDocument doc = PDFParser.load(new File("/PDFBOX-4750.pdf")))
{
PDFRenderer r = new PDFRenderer(doc);
for (int i = 0; i < doc.getNumberOfPages(); ++i)
{
BufferedImage bim1 = r.renderImageWithDPI(i, 96);
ImageIO.write(bim1, "png", new File("/in/PDFBOX-4750-saved.pdf-" +
(i+1) + ".png"));
PDPage page = doc.getPage(i);
PDStream newContent = new PDStream(doc);
try (InputStream is = page.getContents();
OutputStream os =
newContent.createOutputStream(COSName.FLATE_DECODE))
{
PDFStreamParser parser = new PDFStreamParser(is);
parser.parse();
ContentStreamWriter tokenWriter = new ContentStreamWriter(os);
tokenWriter.writeTokens(parser.getTokens());
}
page.setContents(newContent);
}
doc.save(new File("/PDFBOX-4750-saved.pdf"));
}
TestPDFToImage testPDFToImage = new
TestPDFToImage(TestPDFToImage.class.getName());
if (!testPDFToImage.doTestFile(new File("/PDFBOX-4750-saved.pdf"),
"/in", "/out"))
{
fail("Rendering failed or is not identical");
}
{code}
and it succeeded. It also succeeded after the first commit. The following ones
are for clarity and to prevent having too many unneeded spaces in the modified
content stream. You should use the test code above to create your own test. It
creates a first rendering set in the "in" directory and then modifies the file
and then compares the renderings.

Thank you. I'll fix this, also the bug in PDFDebugger, and it will be in the
next release and until then in a snapshot (after comitting).

Yes the /DP segment was by PDFDebugger transformed into spaces - Probably he
can correctly recognize COSNull Element and write it as a empty string in the
result - you can check it in your code. No the null thing is on the page I sent
you.
When I am debugging the content of the Document, I can see the following Java
Objects:
# PDFStreamParser parser = new PDFStreamParser(page);
## loop parser.getTokens()
# One Token is PDFOperator\{BI} - saved in local property op
# COSDictionary dic = op.getImageParameters();
# dic.toString() returns:
COSDictionary\{COSName{Interpolate}:true;COSName\{W}:COSInt\{35};COSName\{H}:COSInt\{26};COSName\{CS}:COSName\{RGB};COSName\{BPC}:COSInt\{8};COSName\{F}:COSArray\{[COSName{A85},
COSName\{DCT}]};COSName\{DP}:COSArray\{[COSNull{}, COSNull{}]};}
I am checking if I can share the whole file with you, but I think it's not
necessary. The method ContentStreamWriter.writeObject should accept COSNull
Object in the same way as the PDFDebugger does.

Uhm, if you can't share the file, then I hope the actual content here isn't
confidential, the text starts with "in der von uns unter" so check whether the
page text is harmless.
The /DP [ ] segment is just three spaces. Could it be that the "null" thing
is in another page? Or check with the hex viewer in PDFDebugger. Or was the
"null" inserted by the software that modified the content stream? Or was
something lost in copy & paste?
This code works fine:
{code}
PDFStreamParser parser = new PDFStreamParser(new
FileInputStream("contentAllOperatorsOfCorruptedPage.txt"));
List tokens = parser.getTokens();
ContentStreamWriter tokenWriter = new ContentStreamWriter(new
ByteArrayOutputStream());
tokenWriter.writeTokens(tokens);

I attached the whole content of corrupted page, extracted from PDFDebugger. At
the end you can see the operator /DP:
/Interpolate true
/W 35
/H 26
/CS /RGB
/BPC 8
/F [ /A85 /DCT ]
/DP [ ]
Unfortunately I can't share the original pdf file.

[jira] [Commented] (PDFBOX-4750) java.io.IOException: Error:Unknown type in content stream:COSNull{}

Tilman Hausherr commented on PDFBOX-4750:
-
Can you share the file? /DP here is an abbreviation for DecodeParms, which can
be an array of dictionaries. It almost makes sense, the filter is an array with
2 elements, A85 and DCT, so DecodeParms if it exists, should have two entries.
And yes, it seems that we should support null.
If you can't share the file, could you share a screenshot of the content
stream? Open it with PDFDebugger and then search the content stream for "/DP"
or "null".

> Project: PDFBox
> Issue Type: Bug
>Affects Versions: 2.0.8, 2.0.18
>Reporter: tomas kochan
>Priority: Major
>
> By removing some optional content for specific document, which is bordered
> with Operator BDC and EMC, we are facing an issue by writing the changed set
> of tokens into PDStream.
> The code looks like:
> PDStream updatedStream = new PDStream(document);
> OutputStream out = updatedStream.getCOSObject().createRawOutputStream();
> ContentStreamWriter tokenWriter = new ContentStreamWriter(out);
> tokenWriter.writeTokens(result);
> out.flush();
> out.close();
> page.setContents(updatedStream);
>
> The following exception occurs at line 'tokenWriter.writeTokens(result);' :
> java.io.IOException: Error:Unknown type in content stream:COSNull{}

> org.apache.pdfbox.pdfwriter.ContentStreamWriter.writeObject(ContentStreamWriter.java:199)

> After the analyze we figured out two issues:
> 1. We assume, the Pdf Document it's self is corrupted, It contains on some
> place operator BI, which is based on the PDF-Reference-V1.7 a begin of inline
> image object. This Operator is not followed by "ID" or "EI" operator.
> Extract from list of Tokens:
> next PDFOperator\{Do}
> next COSFloat\{0.016674607}
> next COSInt\{0}
> next COSInt\{0}
> next COSFloat\{0.061831153}
> next COSFloat\{0.070509767}
> next COSFloat\{-0.302021403}
> next PDFOperator\{cm}
> next PDFOperator\{BI}
> next PDFOperator\{Q}
> next PDFOperator\{Q}
> next COSName\{OC}
> next COSName\{eAkteOptionalContent7}
> next PDFOperator\{BDC}
> Moreover one "DP" Entry in the "BI" operator's COSDictionary contains
> COSArray with COSNull values. However the assumption is, that the COSNull
> values are not forbidden in the Pdf content.
>
> COSDictionary\{COSName{Interpolate}:true;COSName\{W}:COSInt\{35};COSName\{H}:COSInt\{26};COSName\{CS}:COSName\{RGB};COSName\{BPC}:COSInt\{8};COSName\{F}:COSArray\{[COSName{A85},COSName\{DCT}]};COSName\{DP}:COSArray{[COSNull{},COSNull{}]};}
