[gdal-dev] How to deal with IIP image via WMS minidriver?

[Even Rouault]

Carlo,

I've just committed in GDAL trunk a IIP mini driver. Requires a IIP server
that supports the JTL extension (which was the case for the 2 online services I tested).
Online doc at http://www.gdal.org/frmt_wms.html will be refreshed in a few hours.

A few demos:

$ gdalinfo "IIP:http://merovingio.c2rmf.cnrs.fr/fcgi-bin/iipsrv.fcgi?FIF=globe.256x256.tif"

$ gdal_translate -of WMS  "IIP:http://merovingio.c2rmf.cnrs.fr/fcgi-bin/iipsrv.fcgi?FIF=globe.256x256.tif" globe.wms
