Hi Miguel,
I just fixed our wiki...sorry... Try excluding the PDFParser from
the default parser:
<parser class="org.apache.tika.parser.DefaultParser">
<parser-exclude class="org.apache.tika.parser.pdf.PDFParser"/>
</parser>
<parser class="org.apache.tika.parser.pdf.PDFParser">
<params>
<param name="extractInlineImages" type="bool">true</param>
</params>
</parser>
...
What _may_ be happening is that the PDFParser from within the
DefaultParser is being called, and your configured parser is not
working. The other thing that is critical is that you include the
"optional" dependencies that aren't consistent with Apache 2.0:
<dependency>
<groupId>com.levigo.jbig2</groupId>
<artifactId>levigo-jbig2-imageio</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>com.github.jai-imageio</groupId>
<artifactId>jai-imageio-core</artifactId>
<version>1.3.1</version>
</dependency>
<dependency>
<groupId>com.github.jai-imageio</groupId>
<artifactId>jai-imageio-jpeg2000</artifactId>
<version>1.3.0</version>
</dependency>
Let me know how/if this works...
