[postgis-devel] questions about wktraster

   Thanks, it means serialized format needn't consider endian, but in the code: 

when rt_raster_serialize, we just memcpy nodata value to serialized ptr,such as: 
            case PT_16BSI:
            case PT_16BUI:
            {
                uint16_t v = band->nodataval;
                memcpy(ptr, &v, 2); ptr+=2;
                break;
            }

    but when rt_raster_deserialize, we must consider Endian when read nodata value, such as
          case PT_16BSI:
          {
               band->nodataval = read_int16(&ptr, littleEndian);
               break;
          }
   Why?
