Hi Even,
thanks for your quick reply and explanation. I would kindly ask you for more
help, since I'm just trying to adapt this code quickly while still learning
all those concepts...
If I understood you well, those are changes:
hDstDS = GDALCreate(driver, output.c_str(), resX, resY,
4, GDALGetRasterDataType(GDALGetRasterBand(hSrcDS,
1)),
compressOption);
for (int i = 0; i < GDALGetRasterCount(hSrcDS); ++i)
{
GDALRasterBandH hSrcBand = GDALGetRasterBand(hSrcDS, i + 1);
GDALRasterBandH hDstBand = GDALGetRasterBand(hDstDS, i + 1);
GDALColorTableH cTable = GDALGetRasterColorTable(hSrcBand);
GDALSetRasterColorInterpretation(hDstBand,
GDALGetRasterColorInterpretation(hSrcBand));
if (cTable)
{
GDALSetRasterColorTable(hDstBand, cTable);
}
//remove code below????
int success;
double noData = GDALGetRasterNoDataValue(hSrcBand, &success);
if (success)
{
GDALSetRasterNoDataValue(hDstBand, noData);
}
else if (zeroAsTransparent)
{
GDALSetRasterNoDataValue(hDstBand, 0);
}
}
//edit only alpha channel here...if so what do you mean by that, what
methods to use??
Thanks for understanding.
