Here is a piece of source that calculates the transparency for icons in Python

    ## This code Calculates the mask for the list icon.
    #  Here is the list of parameters and function return values.
    #  All white point are transformed to transparent.
    #  Parameter : self The object pointer.
    #  Parameter : aImg An image object.
    #  Returns : Image mask object.
    def _autoMask( self, aImg ):
        width, height = aImg.size
        mask = Image.new( aImg.size, '1' )
        tran = (255,255,255)
        for y in range( height ):
            line = aImg.getpixel( [( x, y ) for x in range( width )] )
        for x in range( width ):
            if line[x] == tran:
                mask.point( ( x, y ), 0 )
        ## Icon mask for dealing with transparency
        self._iDefaultIconMask = mask
