    2929  Why is this method different from ST_SetHeight/ST_SetWidth (which are not in the spec)?

    31 '''ST_SetPixelSize(raster)'''
    32  Set the pixel size (cell size) on the specified raster.
     31'''ST_SetPixelSize(raster, pixelsize)'''
     32 Variant 1: ST_SetPixelSize(raster, xsize, ysize)
     33
     34 Variant 2: ST_SetPixelSize(raster, raster)
     35
     36 Set the pixel size (cell size) on the specified raster. The base method sets the X and Y pixel size to the same value. The first variant sets the pixel sizes to the individually specified x and y sizes.  The second variant sets the pixel size to the pixel size of the 2nd raster parameter.

     38 '''Open Question:'''
     39  Should there be corresponding methods for X/Y sizes?  ST_SetXPixelSize(...) and ST_SetYPixelSize(...)

    3441'''ST_SetNoDataValue(raster, band, value)'''[[BR]]
