[gdal-dev] Accessing a 2D array stored in 1D by GDALRasterIO()

Hi, I loaded an image with: GDALRasterIO(hB,GF_Read,0,0,nX,nY,oneDarray,nX,nY,GDT_Float32,0,0); to run some statistics, however, a new requirement is to make stats per land-use, is there a way to get the index of a given pixel in the 1D array from a given set of row & column? Thank you, Yann
