### Read the Input rasters

# the source raster is of the ASCII format
src = gdal.Open(RasterAPath)
src_Array = src.ReadAsArray()
print("Shape of source raster = " + str(src_Array.shape))

# read destination array
dst = gdal.Open(RasterBPath)
Dst_Array = dst.ReadAsArray()
print("Shape of distnation raster Before matching = " + str(Dst_Array.shape))

### Match the alignment of both rasters
NewRasterB = Raster.MatchRasterAlignment(src, dst)

NewRasterB_array = NewRasterB.ReadAsArray()
print("Shape of distnation  raster after matching = " +
      str(NewRasterB_array.shape))

message = "Error the shape of the result raster does not match the source raster"
assert NewRasterB_array.shape[0] == src_Array.shape[
    0] and NewRasterB_array.shape[1] == src_Array.shape[1], message

### Match the NODataValue

NewRasterB_ND = Raster.MatchNoDataValue(src, NewRasterB)

NoDataValue = NewRasterB_ND.GetRasterBand(1).GetNoDataValue()
