Hello,

Is there a standard method for 'upsampling' 8 bit greyscale images to 16 bit
using MacMegaPov?  I know that POV can read 8 bits and write 16 but without
an imtermediate smoothing step the resultant image isn't any smoother.  I
think what I need is a good old fasioned gaussian blur but am unsure how to
accomplish that within MacMegaPov.  Can anyone advise?

Thanks,

Glenn
