[gdal-dev] Re: corner coords in tif vs ecw

[kmayall]

Sorry, I've been on hiatus for a while.

ECW Image Header Editor shows the top left coords using values from the
coordinate system (screenshot attached), while the gdalinfo results show the
corner coords in pixels.

So there's likely nothing wrong with my ecw file, just a quirk in the
gdalinfo display?
