Hi,<br><br>First of all, thanks to everyone who is there helping solving the problems we have.. <br><br>I'm quite new using GDAL and just realized that when I'm reading the data of an image, all I get are nulls.. This is the code I'm using:<br><br> float* rasterData;<br> nXSize = GDALGetRasterBandXSize( hBand );<br><br> rasterData = (float *) CPLMalloc(sizeof(float)*nXSize/2);<br> GDALRasterIO(hBand, GF_Read, 0,0,nXSize,1,rasterData,nXSize,1,GDT_Float32, 0, 0 );<br><br>I got it from an example and thought that everything was working on well.. I have tried with different data types, not only float, but I always get zeros in all positions of rasterData. The image I'm reading is a TIFF image. Any one has an idea of what is happening??<br><br>Thank you very much!<br><br>Aurora.<br><br><br><br /><hr />Nuevo Windows Live, un mundo lleno de posibilidades <a href='http://www.microsoft.com/windows/windowslive/default.aspx' target='_new'>Descúbrelo.</a></body>
