Struct

ClutterColor

Description [src]

struct ClutterColor {
  guint8 red;
  guint8 green;
  guint8 blue;
  guint8 alpha;
}

A simple type for representing colors.

A ClutterColor is expressed as a 4-tuple of values ranging from zero to 255, one for each color channel plus one for the alpha.

The alpha channel is fully opaque at 255 and fully transparent at 0.

Structure members

red: Red component, between 0 and 255.
green: Green component, between 0 and 255.
blue: Blue component, between 0 and 255.
alpha: Alpha component, between 0 and 255.

Constructors

clutter_color_alloc

Allocates a new, transparent black ClutterColor.

clutter_color_new

Creates a new ClutterColor with the given values.

Functions

clutter_color_from_hls

Converts a color expressed in HLS (hue, luminance and saturation) values into a ClutterColor.

clutter_color_from_pixel

Converts pixel from the packed representation of a four 8 bit channel color to a ClutterColor.

clutter_color_from_string

Parses a string definition of a color, filling the ClutterColor.red, ClutterColor.green, ClutterColor.blue and ClutterColor.alpha fields of color.

Instance methods

clutter_color_copy

Makes a copy of the color structure. The result must be freed using clutter_color_free().

clutter_color_equal

Compares two ClutterColors and checks if they are the same.

clutter_color_free

Frees a color structure created with clutter_color_copy().

clutter_color_hash

Converts a ClutterColor to a hash value.

clutter_color_init

Initializes color with the given values.

clutter_color_interpolate

Interpolates between initial and final ClutterColors using progress.

clutter_color_to_pixel

Converts color into a packed 32 bit integer, containing all the four 8 bit channels used by ClutterColor.

Returns a textual specification of color in the hexadecimal form &num;rrggbbaa, where r, g, b and a are hexadecimal digits representing the red, green, blue and alpha components respectively.
