[mapguide-users] MrSID files through GDAL FDO provider

[Martin Morrison]

If the mapguide tries each provider in order to open an image, how much
performance gain is there by only using one raster format and compiling
only that driver?  Or can you specify the order in which the drivers are
polled?

Andy,

I'm not sure what you mean about this.  The GDAL architecture is such
that
each format driver, in order, is offered a file until one determines
that
it belongs to them and the open proceeds.
