Object hierarchy for RGBA

Description:

[ CCode ( copy_function = "g_boxed_copy" , free_function = "g_boxed_free" , type_id = "gdk_rgba_get_type ()" ) ]
public struct RGBA

A `GdkRGBA` is used to represent a color, in a way that is compatible with cairo’s notion of color.

`GdkRGBA` is a convenient way to pass colors around. It’s based on cairo’s way to deal with colors and mirrors its behavior. All values are in the range from 0.0 to 1.0 inclusive. So the color (0.0, 0.0, 0.0, 0.0) represents transparent black and (1.0, 1.0, 1.0, 1.0) is opaque white. Other values will be clamped to this range when drawing.

Methods:

  • public RGBA? copy ()
    Makes a copy of a `GdkRGBA`.
  • public bool equal (RGBA p2)
    Compares two `GdkRGBA` colors.
  • public void free ()
    Frees a `GdkRGBA`.
  • public uint hash ()
    A hash function suitable for using for a hash table that stores `GdkRGBA`s.
  • public bool is_clear ()
    Checks if an this value is transparent.
  • public bool is_opaque ()
    Checks if an this value is opaque.
  • public bool parse (string spec)
    Parses a textual representation of a color.
  • public string 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.
