gdk.rgba

Module for [RGBA] struct

struct RGBA

Types 1

structRGBA

A [gdk.rgba.RGBA] is used to represent a color, in a way that is compatible with cairo’s notion of color.

[gdk.rgba.RGBA] 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.

Fields

float redThe intensity of the red channel from 0.0 to 1.0 inclusive

float greenThe intensity of the green channel from 0.0 to 1.0 inclusive

float blueThe intensity of the blue channel from 0.0 to 1.0 inclusive

float alphaThe opacity of the color from 0.0 for completely translucent to 1.0 for opaque

void * boxCopy()

gdk.rgba.RGBA copy()Makes a copy of a [gdk.rgba.RGBA].

bool equal(gdk.rgba.RGBA p2)Compares two [gdk.rgba.RGBA] colors.

uint hash()A hash function suitable for using for a hash table that stores [gdk.rgba.RGBA]s. Returns: The hash value for `p`

bool isClear()Checks if an rgba value is transparent.

bool isOpaque()Checks if an rgba value is opaque.

bool parse(string spec)Parses a textual representation of a color.

string toString_()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�...
