Hi, I finally managed to get the GetColorInterpretation() to return the correct values with gdal1.8.0dev but RasterIO() still gives me CE_Failure. [?]
here's a snippet of the code:
poBand = poDataset->GetRasterBand( bandNum );
int nXSize = poBand->GetXSize();
int nYSize = poBand->GetYSize();
GDALColorInterp colorInterp = poBand->GetColorInterpretation();
GDALColorTable *poColorTable = NULL;
if (colorInterp == GCI_PaletteIndex)
{
poColorTable = poBand->GetColorTable();
}
Scanline = new BYTE [nXSize*nYSize];
<< NULL Scanline checking here >>
CPLErr result = poBand->RasterIO( GF_Read, 0, 0, nXSize, nYSize,
Scanline, nXSize, nYSize, GDT_Byte,
0, 0 );
Thanks in advance :)
