The opacity of the color from 0.0 for completely translucent to 1.0 for opaque
The intensity of the blue channel from 0.0 to 1.0 inclusive
The intensity of the green channel from 0.0 to 1.0 inclusive
The intensity of the red channel from 0.0 to 1.0 inclusive
Frees a #GdkRGBA created with gdk_rgba_copy()
A hash function suitable for using for a hash table that stores #GdkRGBAs.
Parses a textual representation of a color, filling in
the red, green, blue and alpha fields of the rgba #GdkRGBA.
The string can be either one of:
Where “r”, “g”, “b” and “a” are respectively the red, green, blue and alpha color values. In the last two cases, “r”, “g”, and “b” are either integers in the range 0 to 255 or percentage values in the range 0% to 100%, and a is a floating point value in the range 0 to 1.
the string specifying the color
Returns a textual specification of rgba 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 gdk_rgba_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.
A #GdkRGBA is used to represent a (possibly translucent) color, in a way that is compatible with cairo’s notion of color.
