Here is a link to a namespace documentation
and example sourcecode that I used in one of my products:
http://www.bsalsa.com/name_space.html
… as for reading images out .. the
easiest is actually to scan the html file for image-tags (don’t forget
css-links, table backgrounds, etc). You will need to do this anyway and replace
those linktags with your own namespace handler url.

Subject: [DUG] The Programmer's
Grail? Streaming Twebbrowser or descendantto DB Blob and back
I am reposting this here, as there are people with expertese who might
not see it in the other placs I have put it.
And I suspect it opens up an area of great usefuleness beyond
Twebbrowser.
I have been looking (as many seem to!) into streaming the content of
Twebbrowser or TembeddedWB into a data base Blob field, seems to be the
grail of this kind of programming!
And generally I want to be able to live re-edit the returned material
in a Twebbrowser window.
Wanting to retain images etc, I have looked at MHT and it seems that it
is possible to use a NameSpace set up to stream them back to the
browser window once in the DB, but I can find no other way than
initally saving to disk to get an MHT out of a browser back to the DB
blob field. I want to avoid using the disk because of the overheads.
So I want to know how I might get a binary representation of the
actual rendering of the HTML in Twebbrowser into a stream and into a
blob and back when wanted. NOT as MHT or HTML! As already rendered
content this stream would be very fast to re-process back into a
Twebbrowser.
It just seems that there must be something like a TCanvas in the
Twebbrowser. But a pure TCanvas may not render the 'data' back into the
browser as edit able material.
** Is there something in how Twebbrowser renders the HTML, a 'binary
layer' that can be streamed back and forward?
** Something that has all the rendered elements and <object> <img>
<etc
..> as binary available for streaming?
Is component streaming an sensible avenue?
i.e. TStream.WriteComponent
