Add support for updating geotransform and projection info of a ECW file

Reported by: rouault Owned by: rouault
Priority: normal Milestone: 1.9.0
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: ecw
Cc: yjacolin

Description

The NCSEcwEditWriteInfo() API enable us to update in place the geotransform and projection info of an existing ECW file. It is then possible to implement SetProjection?(), SetGeoTransform?(). SetMetadataItem?() can be implement to override directly the values of DATUM, PROJ and UNITS for finer control.
