Hi Andreas,
I've commented out the 'do' line, but still cannot get rid of the images.
I've basically opened the document and loaded the resources and then saved
the document. See code below.
This seems to be insufficient. Do I need to parse the PDF stream somehow?
Ups, I guess there was a misunderstanding. My idea won't work if you want to
remove the images permanently. But I have another one, see below

You have to remove all images from the dictionary. I neither test nor compile
that code, but it should make clear how it works.
COSDictionary dictResources = resources.getCOSDictionary();
HashMap<String,PDXObjectImage> images = resources.getImages();
Iterator<String> iter = images.keySet().iterator();
while( iter.hastNext() )
{
dictResources.removeItem(COSName.getPDFName(iter.next()));
}
}
document.save("strippedOfImages.pdf");
}
}
SNIP
We should probably add a removeItem-method to the PDResources class.
