I am looking for a #rendering software for huge images with text. This software should

* have a caching system allowing to load only what's in the view box and around it
* allow pan and zoom
* render text as text (html, pdf or SVG objects embedded in the image), allowing to find elements using a text search, or at least to copy some contents on the clipboard.

The closest I have found to this is SVG with a pan and zoom add-on in the browser. Or sozi, older version, with a few hacks.

But these solutions are not realistic if there is no caching system. I haven't found one.

I would really appreciate any #help . This is a technical difficulty that prevents me from completing a university project that I have invested a lot in.
