here's a side project i've been tinkering on in googlecode svn that
may be useful to some.
it's a simple hack on top of OpenLayers (openlayers.org) to provide a
features. It can be used with any image generation program that can
accept &xmin= and &xmax= parameters through the url. -- though i
havent had it working it bioperl as bioperl generates images of
different height depending on the number of tracks.
there's a live example of the code in SVN here:
with images generated by a colleague's modules on first request. those
images are then cached by a simple perl script included in the SVN
repo. all subsequent requests are returned from the cache.
but any implementation need only implement xmin and xmax. all other
parameters will be used for caching but are not required.
if anyone is interested in getting this going with bioperl image
generation--or improving the project in any way, let me know and i'll
tar ball download:
