No, there's no progress callback available for the Open() call. For WMS, the time is essentially spend in waiting for the response to the GetCapabilities(). So even if there was a mechanism, there would be no way to know the percentage of completion before the server sends the size of the answser XML, but once you know it, as it is small, it is almost instantaneously downloaded. > > Regards, > Maksim Sestic > > > > -- > View this message in context: > http://osgeo-org.1803224.n2.nabble.com/C-bindings-setting-up-progress-delegate-for-Gdal-Open-tp7146342p7146342.html > Sent from the GDAL - Dev mailing list archive at Nabble.com. > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev > _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
