DOCX to FO with Images

[jcizzle]

Hi,

I've been converting DOCX files to XML-FO using the available code, however none of the images in the original document get converted. There appears to be code to support images, and I've tried with GIF, JPG and PNG.

During conversion I see the following exceptions in the log:

Code: Select all

java.lang.NoSuchMethodException: For extension function, could not find method static org.docx4j.model.images.WordXmlPictureE10.createXslFoImgE10([ExpressionContext,] #UNKNOWN (org.docx4j.openpackaging.packages.WordprocessingMLPackage), #STRING, #NODESET, #UNKNOWN (java.util.HashMap)).
   at org.apache.xalan.extensions.MethodResolver.getMethod(MethodResolver.java:276)

From what I can gather the second input is for the image handler which is of type ConversionImageHandler, but the type it's using is String. From the docx2fo.xslt it wasn't clear where the $imageHandler is being created. Could this be an issue with my classpath, any help on this would be appreciated. If this might be a bug, I'd be happy to look into trying to come up with a fix but would need a push in the right direction where to start looking at why the imageHandler is different to the expected type.

Images (both E10 - which are Word 2003 images, and E20) work for me. So:

- Which version of docx4j are you using? (try the most recent nightly at http://www.docx4java.org/docx4j/ )

- Can you post a short sample docx which exhibits the problem?

I was using docx4j 2.7.1 with the exact same JAR's from http://www.docx4java.org/docx4j/docx4j-2.7.1/ (Including all the other dependency jars), I've been running it in Eclipse. I've just tried with docx4j-nightly-20120212.jar and I still get this. I've created a new test case with a single image in it.

This is the exception that I'm getting with this file:

Code: Select all

Hi, your docx contains:

I expect this test docx will actually work for you (as it does for me). Could you try producing another? If you can only do it with sensitive content, you can email me off list if you like.

Hi Jason, thanks for the response, as it's working for you, but not me I decided to take my test out of Eclipse and run the command manually. Doing this worked, so there must be something wrong with my Eclipse project, I'll investigate!
