Hi, I finally managed to get the GetColorInterpretation() to return the correct values with gdal1.8.0dev<div>but RasterIO() still gives me CE_Failure. <img src="cid:35F@goomoji.gmail" style="margin-top: 0px; margin-right: 0.2ex; margin-bottom: 0px; margin-left: 0.2ex; vertical-align: middle; " goomoji="35F"></div>
