Subject Re: Patch: self-contained HTML using Data URI
Date Wed, 25 Jun 2014 09:02:55 GMT
Nick, thanks for the reply.

Let me check I understand you right. WordExtractor will continue to create
<img src="embedded:filename.jpg"/>, and call the ImageParser once for every
file name. But the ImageParser will save the image contents somewhere (in
the metadada?) and when XHTMLContentHandler.startElement is called on "img"
by existing WordParser, it will replace the image src with the data URI.

Is that what you meant? If yes - how do I change the configuration to cause
customized content handler and Image Parse to be used instead of the
current ones?

Thank you very much.
