new(T, S, ...)

Returns: a new object with type S, a subtype of T
Overrides: object.__new__

fromFloat(src, alpha)

Convert a sequence of floating-point values to from_byte(x*255). Alpha is an optional argument and if present unpremultiply by alpha, convert, and then multiply back.

Returns: float list

toFloat(src, alpha)

Convert a sequence of floating-point values to to_byte(x)/255. Alpha is an optional argument and if present unpremultiply by alpha, convert, and then multiply back.

Returns: float list
