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>
</dependency>
...
Best regards,
Philippe

Objet: Re: "About to return NULL from unhandled branch"
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().
