Not specifically for verion QGIS 1.4 from OSGEO4W. I've installed those dlls
long ago for QGIS 1.0.x standalone and never removed them from the system.
In QGIS 1.4 I can open MrSID file with no problems. But opening ecw & jp2
files has problems.

So I copied those 4 dlls to the OSGeo4W\bin folder and, miracle, everything
is working fine:
- opening of ecw and jp2 files does not have problems anymore...
- contour from the raster menu (gdal) does not complain anymore...

Jürgen, you're a star. Many thanks.


Warning for other OSGEO4W users:
On a new installation of OSGEO4W, please copy the 4 dlls from ERMapper SDK
into the OSGEO4W bin folder. Even if the SDK has been previously installed,
OSGEO4W QGIS will not be able to correctly use the installed dlls.

Benoit
