Combinig PIXEL_SIZE and GRID_TYPE_CELL_SIZE in EXPORT_RASTER

I'm trying to produce a set of tiles 0.5 by 0.5 degrees each and export them to corresponding 256 by 256 pixels PNG files using EXPORT_RASTER command in my script.
I tried to specify PIXEL_SIZE="256,256" GRID_TYPE_CELL_SIZE="0.5,0.5" arguments to EXPORT_RASTER command, but it seems like the resulting PNG files contain correct data, but their size is far from being 256x256 pixels.
Does combination of PIXEL_SIZE and GRID_TYPE_CELL_SIZE arguments of
EXPORT_RASTER command work? Are those arguments mutually exclusive?

    Yes, those are mutually exclusive. Try using SPATIAL_RES=0.001953125 (that is 0.5 / 256) and you should get the cells to be 256x256 in size through the combination of cell size and spatial resolution.

    Let me know if I can be of further assistance.

    Thanks,
