to_string

Returns a textual specification of this in the form `rgb(r,g,b)` or `rgba(r g,b,a)`, where “r”, “g”, “b” and “a” represent the red, green, blue and alpha values respectively.

“r”, “g”, and “b” are represented as integers in the range 0 to 255, and “a” is represented as a floating point value in the range 0 to 1.

These string forms are string forms that are supported by the CSS3 colors module, and can be parsed by parse.

Note that this string representation may lose some precision, since “r”, “g” and “b” are represented as 8-bit integers. If this is a concern, you should use a different representation.

Parameters:

a RGBA

A newly allocated text string
