Hi,
the map:read can only read images direct. If you want to get
your images from your db, then you have to create an own
reader (java-component, no xsp) that query your db and write
the image to the reponse-stream direct.
But i see you have the images base64 endcoded, isnt it?
You can now simple create a pipeline like this.
<map:match pattern="*.jpg">
<map:generate type="serverpages" src="my.xsp" />
<!-- your xsp, that get the images from db and make a
svg here-->
<map:serialize type="svg2jpeg"/>
</map:match>
Your XSP should give a SVG-XML-document like:
<svg width="...." height="......">
<image xmlns:xlink="http://www.w3.org/1999/xlink
xlink:href="data:image/png;base64,!!!your base64 string
here !!!"/>
</svg>
Best Regards,
Simon
