Hi Tilman,
please find below the shortest possible code to reproduce the error,
as requested.
The message I get is as follows:
Oct 20, 2014 10:08:45 AM
org.apache.pdfbox.pdmodel.graphics.xobject.PDXObjectImage getColorSpace
INFO: About to return NULL from unhandled branch. filter =
COSName{DCTDecode}
My pom.xml contains the following entries:
<properties>
<pdfbox.version>1.8.7</pdfbox.version>
...
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>${pdfbox.version}</version>

Best regards,
Philippe

If you are sure that you get this error with 1.8.7, then please post the
shortest possible code that reproduces the error.
I just used the PDFToImage or PDFReader commands from the command line
application, which calls PDPage.convertToImage().

Hi,
I downloaded the file at the link you gave me (I assume you don't want
it to become public), and I didn't get the error you mention, I get
many warnings:

The reason are sequences like this in the PDF:
708 388.2756347656 m
708 380.2756347656 l
S
h
/F1 8 Tf
0 0 0 rg
BT
31 381.2756347656 Td
9.52 TL
() Tj
T*
ET
h
h = closepath ("connects the end of a subpath back to its starting
point"). The last "h" doesn't have a starting point.
However the pages are rendered, I tested with 1.8.7, 1.8.6, 1.8.8 and
2.0.
Either you are using a much older version, or you uploaded the wrong
file.

That error is a follow-up error on another error. There was probably
a problem with the DCTDecode filter, i.e. a JPEG in the PDF. Please
upload the PDF somewhere, as you can't attach it here.

Hi,
When I run a Java program that uses the PdfBox 1.8.7 API, the
following message appears several times:
"About to return NULL from unhandled branch. filter =
COSName{DCTDecode}"
Does anyone have any idea what might cause it?
Many thanks.
Cheers,
Philippe
